ISO 27001 Continuous Improvement: Surveillance Audits and ISMS Maintenance

Achieving ISO 27001 certification is a significant milestone. Maintaining it is a different challenge entirely. The certification body does not hand you a certificate and walk away for three years. ISO 27001 operates on a three-year certification cycle with annual surveillance audits that verify your ISMS continues to operate effectively, adapts to changing risks, and genuinely improves over time.

Many SaaS companies treat certification as a project with a finish line. They invest heavily in building the ISMS, push through the certification audit, celebrate the result, and then gradually let compliance activities fade until the next audit approaches. This approach fails. Surveillance auditors will detect the gaps. Controls that operated effectively during the initial certification period but degraded afterward will generate findings. Management reviews that stopped happening will be noticed. Risk assessments that were not updated will be questioned.

ISO 27001 is fundamentally a management system standard, and management systems require ongoing operation. Clause 10 explicitly requires continual improvement. This guide covers the three-year certification cycle, what surveillance auditors expect, how to run effective management reviews, the metrics that demonstrate your ISMS is functioning, and how to build an improvement culture that keeps your ISMS healthy between audits.

The Three-Year Certification Cycle

ISO 27001 certification follows a predictable three-year cycle. Understanding the structure helps you plan resources, maintain readiness, and avoid surprises.

Year 0: Initial Certification Audit

The initial certification audit is a two-stage process:

Stage 1 (documentation review). The certification body reviews your ISMS documentation: policies, risk assessment, Statement of Applicability, internal audit reports, management review minutes, and procedures. Stage 1 verifies that your ISMS is designed correctly and that you are ready for the Stage 2 audit. Stage 1 typically results in observations — areas where documentation needs strengthening or where the auditor wants to examine specific things in Stage 2.

Stage 2 (implementation audit). The certification body audits your ISMS in operation. They interview personnel, examine evidence of controls operating, verify that processes are being followed, and test that the ISMS is achieving its intended outcomes. Stage 2 can result in nonconformities (major or minor), observations, and opportunities for improvement.

If no major nonconformities are identified (or if identified major nonconformities are resolved within the agreed timeframe), the certification body issues your ISO 27001 certificate. The certificate is valid for three years from the date of the certification decision.

For a complete walkthrough of the certification process, see our ISO 27001 certification checklist.

Year 1: First Surveillance Audit

Approximately 12 months after initial certification, the certification body conducts the first surveillance audit. This is not a full recertification — it is a focused review of specific ISMS areas, chosen by the auditor based on risk and the initial certification findings.

What surveillance auditors examine:

• Follow-up on initial audit findings. If the certification audit identified minor nonconformities or observations, the surveillance auditor will verify that you addressed them. Nonconformities that were supposedly corrected but show evidence of recurrence are a significant concern.
• Internal audit results (Clause 9.2). The auditor will review your internal audit program: were audits conducted on schedule? Were the findings addressed? Is the internal audit program covering the full ISMS scope over time?
• Management review outputs (Clause 9.3). The auditor will review management review minutes to verify that senior management is actively engaged in ISMS oversight. Empty or pro forma management reviews are a common surveillance finding.
• Corrective actions (Clause 10.1). The auditor will examine your corrective action process: are nonconformities being identified, root causes analyzed, and corrective actions implemented and verified?
• Continual improvement evidence (Clause 10). The auditor wants to see that your ISMS is not static. What has improved since the initial certification? Have controls been strengthened? Have new risks been addressed? Have processes been refined based on experience?
• Selected Annex A controls. The auditor will sample specific controls to verify they continue to operate effectively. The controls selected will vary from audit to audit, ensuring full coverage over the three-year cycle.
• Changes since last audit. The auditor will ask about significant changes: new products, new markets, organizational restructuring, technology changes, regulatory changes. They want to understand whether these changes were assessed for their impact on the ISMS and whether the ISMS was updated accordingly.

Surveillance audit duration. Surveillance audits are shorter than certification audits — typically 1-3 days depending on your organization’s size and ISMS scope. However, do not mistake “shorter” for “less rigorous.” Surveillance auditors are experienced professionals who know where to look for degradation.

Possible outcomes:

• No findings: The ISMS continues to operate effectively. Certificate maintained.
• Minor nonconformities: Specific requirements of the standard are not fully met, but the issue does not compromise the ISMS’s overall effectiveness. You are given a defined period (typically 90 days) to implement corrective action.
• Major nonconformities: A significant failure to meet a standard requirement, or a situation where the ISMS cannot achieve its intended outcomes. This is serious. If not resolved within the agreed timeframe, the certification body may suspend your certificate.
• Observations and opportunities for improvement: Advisory notes that are not nonconformities but indicate areas where the ISMS could be strengthened. Address these proactively — they often become minor nonconformities in the next audit if ignored.

Year 2: Second Surveillance Audit

The second surveillance audit follows the same structure as the first but examines different areas of the ISMS. Over the three-year cycle, the combination of the initial certification audit and two surveillance audits should cover the full scope of your ISMS.

What changes in Year 2:

• The auditor selects different Annex A controls to test, ensuring breadth of coverage
• The auditor expects to see maturation — your ISMS should be more refined in Year 2 than it was at certification
• If Year 1 surveillance identified observations, the Year 2 auditor will check whether you addressed them
• The auditor may begin discussing recertification planning and any scope changes anticipated for the next cycle

Year 3: Recertification Audit

Before your certificate expires (typically conducted 2-3 months before the expiry date), the certification body conducts a recertification audit. This is essentially a full reassessment of your ISMS — similar in scope to the initial certification audit, though with the benefit of the certification body’s familiarity with your organization.

Recertification audit scope:

• Review of the entire ISMS against all requirements of ISO 27001
• Evaluation of the ISMS’s overall effectiveness over the three-year cycle
• Review of all surveillance audit findings and their resolution
• Assessment of significant changes that occurred during the cycle
• Verification that continual improvement has been demonstrated over three years
• Review of internal audit and management review records for the full cycle

Recertification versus initial certification: Recertification audits are generally shorter than initial certification audits because the certification body already understands your ISMS. However, the standard of evidence is the same, and auditors expect to see a more mature ISMS than was present at initial certification. An ISMS that looks the same in Year 3 as it did in Year 0 has not met the continual improvement requirement.

If the recertification audit is successful, a new three-year certificate is issued and the cycle begins again.

Management Review: Clause 9.3

Management review is the mechanism through which senior management exercises oversight of the ISMS. ISO 27001 Clause 9.3 defines specific inputs the management review must consider and specific outputs it must produce. Surveillance auditors give this clause particular attention because it demonstrates whether leadership is genuinely engaged or merely signing documents.

Required Inputs

The management review must consider the following inputs. Auditors will check that each of these was actually addressed in your management review, not merely listed on an agenda.

Status of actions from previous management reviews. Were the decisions and actions from the last management review actually implemented? Open action items that carry forward from review to review signal that management review is a ceremonial exercise rather than a governance mechanism.

Changes in external and internal issues relevant to the ISMS. What has changed in your operating environment since the last review? New regulations, new business lines, organizational restructuring, significant technology changes, changes in the threat landscape, new customer requirements. The ISMS must respond to these changes, and management review is where the response is decided.

Feedback on the information security performance, including trends in:

• Nonconformities and corrective actions: How many nonconformities were identified? Were root causes addressed? Are there patterns indicating systemic issues?
• Monitoring and measurement results: What do your ISMS metrics show? Are controls operating effectively? Are targets being met?
• Audit results: What did internal audits and the most recent surveillance audit find? Are audit findings being addressed in a timely manner?
• Fulfilment of information security objectives: Are you achieving the objectives you set in your information security policy and risk treatment plan?

Feedback from interested parties. What are customers, regulators, partners, and employees saying about information security? Customer security questionnaire responses, regulatory correspondence, partner audit requests, and employee security feedback all qualify.

Results of risk assessment and status of risk treatment plan. Has the risk landscape changed? Are risk treatment actions on track? Have new risks been identified? Has the effectiveness of existing controls changed? Your risk assessment should be a living document that feeds into every management review.

Opportunities for continual improvement. What improvements have been identified through audits, incidents, metrics analysis, industry benchmarking, or team observations? Management review is where improvement initiatives are approved and resourced.

Required Outputs

The management review must produce decisions and actions related to:

Continual improvement opportunities. Specific improvement initiatives that management approves, with assigned owners and timelines. “We should improve our access review process” is not an output. “Engineering will implement automated access review for production systems by Q2, owned by the Security Lead” is an output.

Need for changes to the ISMS. If the management review identifies that the ISMS needs to change — scope modifications, updated policies, new controls, revised risk appetite — these decisions must be documented and actioned.

Resource needs. If the ISMS requires additional resources — budget, headcount, tools, training — management review is where those needs are identified and approved. An ISMS that is under-resourced will degrade, and management review is the governance mechanism for preventing that.

Making Management Review Effective

Frequency. ISO 27001 requires management review at “planned intervals” but does not prescribe a specific frequency. For most SaaS companies, quarterly management reviews work well — frequent enough to maintain engagement and respond to changes promptly, but not so frequent that they become routine and superficial. At minimum, conduct management review twice per year.

Participants. Management review must involve top management — the individuals with authority and accountability for the ISMS. For SaaS companies, this typically includes the CEO or COO, CTO, CISO or Security Lead, VP of Engineering, and the ISMS Manager or GRC Lead. Having the right people in the room ensures that decisions are made and resources are allocated.

Preparation. The effectiveness of management review depends on the quality of preparation. The ISMS Manager should compile a management review package at least one week before the meeting, including current metrics, risk register updates, audit findings, incident summaries, and proposed improvement initiatives. Management cannot make informed decisions without complete information.

Documentation. Document the management review proceedings: who attended, what was discussed, what was decided, and what actions were assigned. These minutes are primary audit evidence. Auditors will read them carefully and compare them against the Clause 9.3 requirements to verify that all required inputs were considered and that the outputs are substantive.

Continual Improvement: Clause 10

Clause 10 is the heart of ISO 27001’s continuous improvement requirement. It addresses both reactive improvement (fixing things that went wrong) and proactive improvement (making things better even when they are working).

Clause 10.1 — Nonconformity and Corrective Action

When something in your ISMS does not meet a requirement — whether identified through internal audit, surveillance audit, incident analysis, or operational monitoring — it is a nonconformity. Clause 10.1 defines the required response:

React to the nonconformity. Take immediate action to control and correct the nonconformity and deal with its consequences. If a control failed, implement a temporary compensating control while you address the root cause.

Evaluate the need for action to eliminate causes. Determine whether the nonconformity could recur or whether similar nonconformities could occur elsewhere. Root cause analysis is the tool for this evaluation. A control failure caused by a single misconfiguration may require only a targeted fix. A control failure caused by inadequate training, unclear procedures, or architectural weaknesses requires broader corrective action.

Implement corrective action. Based on the root cause analysis, implement changes that address the underlying cause. Corrective actions may include procedure revisions, additional training, control redesign, tool implementation, or organizational changes.

Review the effectiveness of corrective action. After implementing the corrective action, verify that it actually resolved the problem. If the same nonconformity recurs, the corrective action was ineffective and needs to be revisited.

Make changes to the ISMS if necessary. If the nonconformity reveals a systemic issue, update the ISMS itself — policies, procedures, risk assessments, control frameworks, or organizational structures.

Document everything. Maintain records of the nonconformity, root cause analysis, corrective actions taken, and the results of verification. This documentation is essential audit evidence.

Clause 10.2 — Continual Improvement

Beyond fixing nonconformities, Clause 10.2 requires that you continually improve the suitability, adequacy, and effectiveness of the ISMS. This is a proactive obligation — your ISMS should get better over time, not just avoid getting worse.

Sources of improvement opportunities:

• Internal audit findings: Even observations (not just nonconformities) are improvement opportunities
• Surveillance audit observations: Certification body auditors bring external perspective and industry knowledge
• Incident post-mortem action items: Every incident should generate improvements
• Risk assessment updates: Changes in the risk landscape drive control improvements
• Industry benchmarking: Comparing your practices against industry standards and peer organizations
• Technology evolution: New tools and capabilities that can strengthen your ISMS
• Employee feedback: The people operating controls daily often have the best insights into how they could be improved
• Customer and partner feedback: Security questionnaires, audit requests, and customer conversations reveal expectations that your ISMS should meet

Tracking improvements. Maintain a continual improvement register that captures identified opportunities, prioritization, assigned owners, target completion dates, and actual outcomes. This register is audit evidence and provides a clear narrative of how your ISMS has matured over time.

ISMS Metrics and KPIs

Metrics transform ISMS performance from subjective opinion into objective measurement. Clause 9.1 requires monitoring and measurement, and surveillance auditors expect to see meaningful metrics that inform management decisions.

Operational Metrics

Access control metrics:

• Time to provision new user access (target: within 24 hours of start date)
• Time to deprovision terminated user access (target: within 24 hours of termination)
• Percentage of users with MFA enabled across all systems (target: 100%)
• Quarterly access review completion rate (target: 100% on schedule)
• Number of excessive privilege findings from access reviews

Vulnerability management metrics:

• Mean time to patch critical vulnerabilities (target: within 72 hours)
• Mean time to patch high vulnerabilities (target: within 30 days)
• Percentage of systems scanned on schedule (target: 100%)
• Number of overdue vulnerabilities by severity
• Vulnerability recurrence rate (same vulnerability reappearing after remediation)

Incident management metrics:

• Number of security events and incidents by severity
• Mean time to detect (MTTD)
• Mean time to respond (MTTR)
• Mean time to contain (MTTC)
• Post-incident action item completion rate
• Incident recurrence rate

Change management metrics:

• Percentage of changes following the defined change management process (target: 100%)
• Emergency change frequency (should be low and trending downward)
• Change-related incidents (changes that caused security events or outages)
• Change rollback rate

Training and awareness metrics:

• Security awareness training completion rate (target: 100% annually)
• Phishing simulation click rate (should trend downward over time)
• Time to complete training for new hires

ISMS Program Metrics

Risk management metrics:

• Number of identified risks by severity
• Percentage of risks with completed treatment plans
• Risk treatment action completion rate
• Number of new risks identified since last review
• Number of risk acceptances approved by management

Audit and compliance metrics:

• Internal audit plan completion rate (target: 100%)
• Number of nonconformities by category and severity
• Corrective action completion rate within defined timelines
• Mean time to resolve nonconformities
• Surveillance audit findings (trending year over year)

Supplier management metrics:

• Percentage of Tier 1 suppliers with current security documentation
• Supplier security assessment completion rate
• Number of supplier security incidents reported
• Overdue supplier reviews

Policy and documentation metrics:

• Percentage of policies reviewed within their review cycle
• Document update turnaround time
• Policy acknowledgment rate

Presenting Metrics in Management Review

Raw metrics are data. Management needs information. Present metrics in context:

• Trends over time. A single measurement is a data point. Three quarters of measurements show a trend. Present trends and explain what is driving them.
• Against targets. Every metric should have a target. Show performance against the target and explain variances.
• With impact analysis. When a metric is off target, explain the impact on information security risk and the actions being taken.
• With resource implications. If improving a metric requires additional resources, present the business case in the management review.

Business Continuity: Controls A.5.29 and A.5.30

ISO 27001:2022 includes two controls related to business continuity that are often examined during surveillance audits because they demonstrate the ISMS’s operational resilience.

A.5.29 — Information Security During Disruption

This control requires that you plan how to maintain information security at an appropriate level during adverse situations — business disruptions, crises, or disasters. Information security controls must not be abandoned during a crisis just because operational pressures increase.

For SaaS companies, this means:

• Your disaster recovery procedures must maintain security controls (access management, encryption, logging) even in failover scenarios
• Business continuity testing must verify that security controls function correctly in recovery environments
• Temporary workarounds implemented during disruptions must be assessed for security impact and removed when normal operations resume
• Incident response procedures must account for scenarios where primary security tools are unavailable

A.5.30 — ICT Readiness for Business Continuity

This control requires that you plan, implement, maintain, and test ICT readiness to ensure business continuity. For SaaS companies, this is directly about your ability to maintain service availability and data integrity when things go wrong.

Key requirements:

• Define recovery time objectives (RTOs) and recovery point objectives (RPOs) for critical systems
• Implement and maintain backup and recovery procedures
• Test recovery procedures regularly (at least annually, more often for critical systems)
• Document test results and any failures or gaps discovered
• Ensure recovery procedures are updated when systems change

SaaS-specific considerations:

• Multi-region failover testing — verify that your application fails over to secondary regions correctly and that security controls are maintained in the failover configuration
• Database recovery testing — verify that backups are restorable and that data integrity is maintained after recovery
• Dependency failure testing — what happens when a critical third-party service becomes unavailable? Verify that your application degrades gracefully and that security controls are not bypassed in degraded mode
• Runbook documentation — maintain step-by-step recovery procedures that can be executed by on-call engineers who may not be the engineers who built the system

Scope Changes and Their Impact

SaaS companies evolve rapidly. New products, new markets, acquisitions, technology migrations, and organizational restructuring can all affect the scope of your ISMS. ISO 27001 requires that scope changes be managed deliberately.

When Scope Changes Are Needed

New products or services. If you launch a new product that processes customer data differently from your existing products, it may need to be included in the ISMS scope. Assess whether existing controls cover the new product or whether new controls are needed.

Geographic expansion. Entering new markets — particularly markets with specific regulatory requirements (GDPR for EU, LGPD for Brazil, PIPL for China) — may require scope adjustments to address new legal and regulatory obligations.

Technology changes. Migrating from one cloud provider to another, adopting a new architecture (microservices, serverless), or implementing new development frameworks all affect the technical scope of your ISMS.

Organizational changes. Acquisitions, mergers, and restructuring change the organizational context of your ISMS. Acquired entities may need to be integrated into the ISMS scope or may operate under a separate ISMS.

Customer requirements. Enterprise customers may require that specific systems or processes be within your ISMS scope as a condition of doing business.

Managing Scope Changes

Assess the impact. Before making a scope change, assess its impact on every element of your ISMS: risk assessment, Statement of Applicability, controls, policies, procedures, and audit plan.

Update documentation. Revise your ISMS scope statement, risk assessment, Statement of Applicability, and any affected policies and procedures. The Statement of Applicability must be updated to reflect any new controls required by the scope change.

Notify your certification body. Significant scope changes must be communicated to your certification body. They will determine whether the change requires an additional audit or can be assessed during the next scheduled surveillance audit. Failing to notify the certification body of material scope changes can jeopardize your certification.

Implement new controls. If the scope change requires new controls, implement them with the same rigor as your initial ISMS implementation: document the controls, assign ownership, define monitoring procedures, and collect evidence of operating effectiveness.

Test through internal audit. Use your internal audit program to verify that scope changes have been properly implemented and that new controls are operating effectively before the certification body examines them.

Common Reasons Companies Lose Certification

Understanding why companies lose ISO 27001 certification helps you avoid the same pitfalls.

Failure to conduct surveillance audits. If you do not schedule and complete surveillance audits within the required timeframe (typically within 12 months of the previous audit, with some flexibility), your certification body will suspend your certificate. Suspension becomes withdrawal if the audit is not completed within a defined period.

Unresolved major nonconformities. When a surveillance audit identifies a major nonconformity, you are given a defined period (typically 90 days) to implement corrective action. If you fail to resolve the nonconformity within that period, the certification body may suspend or withdraw your certificate.

Management disengagement. When management reviews stop happening, or when they become pro forma exercises without substantive discussion or actionable outputs, the ISMS loses its governance mechanism. Auditors detect this quickly — empty management review minutes with no decisions and no action items are a clear indicator.

Risk assessment stagnation. An ISMS whose risk assessment has not been updated since initial certification is not meeting the standard’s requirements. Risks change as your business evolves, as the threat landscape shifts, and as new vulnerabilities are discovered. A static risk assessment means your controls may no longer address your actual risks.

Internal audit program failure. If internal audits are not being conducted on schedule, or if internal audit findings are not being addressed, the self-assessment mechanism of the ISMS has broken down. Auditors rely on your internal audit program as evidence that you are monitoring your own compliance. Without it, they have less confidence in the ISMS’s overall effectiveness.

Control degradation without detection. Controls that were operating effectively at certification may degrade over time: access reviews that stop happening, vulnerability scanning that gets disabled during a migration and never re-enabled, change management procedures that are bypassed during emergencies and never restored. Without monitoring and measurement (Clause 9.1), this degradation goes undetected until the next audit.

Scope changes without ISMS updates. Launching a new product, migrating to a new cloud provider, or acquiring another company without updating the ISMS creates gaps between what the ISMS covers and what it should cover. Auditors will identify these gaps.

Budget cuts to the security program. Economic pressure sometimes leads to cuts in security staffing, tooling, or training budgets. If these cuts compromise the ISMS’s ability to operate effectively, the result is control failures that auditors will find.

Building an Improvement Culture

Continuous improvement is not just a clause in a standard — it is a cultural characteristic of organizations that maintain robust information security over time.

Leadership Commitment

Continuous improvement starts with leadership. When senior management actively participates in management reviews, asks substantive questions about security metrics, approves improvement initiatives with real budgets, and holds people accountable for corrective actions, the organization takes improvement seriously. When management treats the ISMS as a compliance checkbox, the rest of the organization follows suit.

Practical leadership actions:

• Attend every management review and engage with the content
• Ask about the status of improvement initiatives and corrective actions
• Allocate budget for security improvements identified through audits and incident reviews
• Recognize teams and individuals who identify improvement opportunities
• Include information security performance in organizational performance metrics

Embedding Improvement in Daily Operations

Continuous improvement should not be a separate activity bolted onto your operations. It should be embedded in your existing workflows.

Retrospectives that include security. If your engineering teams run sprint retrospectives, include information security as a topic. Were there any security-related issues during the sprint? Are there controls that are slowing the team down unnecessarily? Are there security improvements the team has been wanting to make?

Blameless incident reviews. When incidents occur, conduct blameless post-mortems that focus on systemic improvements rather than individual fault. Teams that feel safe reporting security issues and honest about what went wrong produce far better improvement insights than teams operating under fear of blame.

Security champions. Designate security champions within each engineering team. These individuals serve as the bridge between the security team and their product team, identify security improvement opportunities specific to their domain, and promote security-conscious development practices.

Automation as improvement. Many ISMS improvements can be implemented through automation: automated access reviews, automated vulnerability scanning, automated compliance monitoring, automated evidence collection. Each automation reduces manual effort, improves consistency, and frees up human attention for higher-value security work.

Measuring Improvement

To demonstrate that your ISMS is genuinely improving, track improvement indicators over time:

• Nonconformity trends: Are the number and severity of nonconformities decreasing over time?
• Corrective action timeliness: Are corrective actions being completed faster?
• Incident trends: Are incident frequency and severity decreasing? Is detection getting faster?
• Audit findings: Are surveillance audit findings decreasing year over year?
• Metric performance: Are your ISMS KPIs trending toward their targets?
• Control maturity: Are controls becoming more automated, more reliable, and more effective?

Present these improvement trends in management review to demonstrate that the ISMS is meeting its Clause 10.2 obligation. Certification body auditors will specifically look for evidence of improvement between surveillance audits.

Preparing for Surveillance Audits: A Practical Checklist

Use this checklist to ensure readiness for each surveillance audit:

90 days before the audit:

• Confirm the audit date with your certification body
• Review all findings from the previous audit and verify that corrective actions are complete and effective
• Ensure the internal audit program is on schedule and that recent internal audit reports are finalized
• Schedule a management review if one has not been conducted within the last quarter

60 days before the audit:

• Compile your ISMS metrics and ensure they are current
• Review the risk register and verify it has been updated to reflect current risks
• Verify that all policies and procedures have been reviewed within their review cycles
• Check that all Tier 1 supplier security documentation is current (see supplier management)
• Review recent incident records and verify that post-incident actions are complete

30 days before the audit:

• Conduct a pre-audit self-assessment against the clauses and controls the auditor is likely to examine
• Prepare evidence packages for key control areas
• Brief key personnel who may be interviewed by the auditor
• Ensure that the management review minutes demonstrate substantive discussion and actionable outputs
• Verify that your continual improvement register shows concrete improvements since the last audit

Audit week:

• Have your ISMS documentation readily accessible (not scattered across multiple systems)
• Ensure that the ISMS Manager or GRC Lead is available throughout the audit
• Have subject matter experts on standby for the control areas being examined
• Prepare a quiet, equipped room for the auditor with access to necessary systems and documents
• Conduct a brief team alignment meeting to confirm everyone understands their role during the audit

Linking Continuous Improvement to SOC 2

If your organization maintains both ISO 27001 and SOC 2 compliance, your continuous improvement activities serve both frameworks. SOC 2’s continuous monitoring expectations align closely with ISO 27001’s measurement and improvement requirements. Specifically:

• ISO 27001 management review outputs can serve as evidence for SOC 2 management assertion requirements
• ISO 27001 internal audit findings can inform SOC 2 control monitoring activities
• ISO 27001 corrective action tracking provides evidence for SOC 2 remediation and improvement
• ISMS metrics and KPIs can be reported in both ISO 27001 management reviews and SOC 2 audit evidence

Maintaining a unified improvement program that serves both frameworks reduces duplication of effort and provides a more comprehensive view of your security posture.
