SOC 2 Compliance Checklist for SaaS Companies

SOC 2 compliance is a multi-phase effort — and the SaaS companies that treat it as a structured project, rather than a scramble before audit season, are the ones that pass cleanly and stay compliant year after year.

This checklist covers the full lifecycle: from initial scoping decisions through audit completion and into ongoing compliance. Each section links to a detailed guide where you can dive deeper into specific topics. Whether you’re pursuing your first SOC 2 report or tightening up for your next audit cycle, use this as your operational roadmap.

If you’re new to SOC 2 entirely, start with our What Is SOC 2? guide for the foundational concepts before working through this checklist.

Phase 1: Scoping and Planning

The decisions you make during scoping define the cost, timeline, and complexity of everything that follows. Get this phase right and the rest of the process becomes dramatically more manageable.

Define Which Trust Service Criteria to Include

Every SOC 2 report must include the Security criterion (also called the Common Criteria). The remaining four — Availability, Processing Integrity, Confidentiality, and Privacy — are optional and should be selected based on your customers’ requirements and the nature of your service.

In practice: Most B2B SaaS companies start with Security and Availability. If your product handles sensitive data with strict access controls, add Confidentiality. If you process personal data at scale and want to demonstrate GDPR alignment, include Privacy.

Don’t include criteria “just in case.” Each additional criterion adds controls, evidence requirements, and audit scope. Include what your customers ask for and what’s genuinely relevant to your service.

Decide Type I or Type II

Type I evaluates your control design at a point in time. Type II evaluates design and operating effectiveness over a period (typically 6-12 months). Enterprise customers strongly prefer Type II because it demonstrates sustained control operation, not just a snapshot.

SaaS example: A Series A startup closing its first enterprise deal might pursue a Type I to unblock the sale, then transition to Type II within the next 12 months. A Series B company with an established customer base should go straight to Type II.

Set Budget and Timeline

SOC 2 costs vary significantly depending on your company size, audit scope, and whether you use a compliance platform or consultants. Auditor fees alone typically range from $20,000 to $80,000 for a Type II engagement. Add tooling, remediation costs, and internal engineering time, and total first-year costs for a mid-stage SaaS company often land between $50,000 and $150,000.

Timeline guidance: A Type I report can be completed in 2-4 months if your foundational controls are in place. A Type II report requires a 6-12 month observation period after controls are implemented, meaning you should start 9-15 months before you need the report in hand.

Select an Auditor

Only a licensed CPA firm can issue a SOC 2 report. Choose a firm with demonstrable SaaS experience — auditors who understand cloud infrastructure, CI/CD pipelines, and infrastructure-as-code will ask relevant questions and won’t waste your team’s time on controls designed for on-premise environments.

What to evaluate:

• Experience auditing SaaS companies of your size and stage
• Familiarity with your tech stack (AWS/GCP/Azure, Kubernetes, etc.)
• Communication style and responsiveness during the engagement
• Pricing transparency — watch for hidden fees around remediation retesting
• References from other SaaS companies they’ve audited

Define the System Boundary

The system boundary defines what’s in scope for your SOC 2 audit. This includes infrastructure, software, people, procedures, and data related to the service you’re evaluating.

In practice: For a typical SaaS application, the system boundary includes your production environment, the CI/CD pipeline that deploys to it, the monitoring and alerting systems, the people who access it, and the policies that govern their behavior. Development and staging environments are usually excluded unless they contain customer data.

Be precise. An overly broad system boundary means more controls, more evidence, and more cost. An overly narrow one means your report won’t cover what customers actually care about.

Phase 2: Risk Assessment and Gap Analysis

Before implementing controls, you need to understand your current state: what risks exist, what controls are already in place, and where the gaps are.

Conduct a Formal Risk Assessment

A SOC 2 risk assessment identifies threats to your system, evaluates their likelihood and impact, and documents how you mitigate them. This isn’t a theoretical exercise — it’s the foundation your controls are built on, and your auditor will review it.

What to assess:

• External threats: unauthorized access attempts, DDoS attacks, supply chain compromises, social engineering
• Internal threats: employee errors, insider threats, misconfigurations, inadequate access controls
• Environmental threats: cloud provider outages, natural disasters affecting availability, third-party service failures
• Compliance threats: regulatory changes, customer contractual requirements, data residency obligations

SaaS example: Your risk assessment identifies that engineers have standing access to production databases containing customer data. The risk: an engineer’s compromised credentials could expose customer data. The mitigation: implement just-in-time access with approval workflows and session logging.

Identify Gaps Against SOC 2 Common Criteria

Map your existing controls against the SOC 2 Common Criteria (the CC-series control points). This gap analysis tells you exactly what you need to build, formalize, or document before the audit.

Common gaps SaaS companies discover:

• Policies exist informally but aren’t documented
• Access reviews happen ad hoc but aren’t scheduled and logged
• Incident response procedures exist in someone’s head but not in a runbook
• Vendor risk assessments are done during onboarding but never revisited
• Change management exists in pull request workflows but isn’t formally documented as a control

Prioritize Remediation Based on Risk Level

Not all gaps carry equal weight. Prioritize based on risk level (from your risk assessment) and audit criticality (whether the gap would result in a qualified opinion).

In practice: A missing information security policy is a critical gap — it underpins multiple control areas and your auditor will flag it immediately. A missing annual review of your acceptable use policy is important but lower priority. Build a remediation plan with owners, deadlines, and status tracking.

Phase 3: Policies and Controls

This is where compliance moves from planning to implementation. Your policies define what you commit to do. Your controls are the mechanisms that enforce those commitments.

Draft Required Policies

SOC 2 requires documented policies across multiple domains. Your auditor will review these policies, test whether your team follows them, and evaluate whether they’re appropriately reviewed and updated.

Core policies you’ll need:

• Information Security Policy
• Access Control Policy
• Change Management Policy
• Incident Response Policy
• Risk Assessment Policy
• Vendor Management Policy
• Data Classification and Handling Policy
• Business Continuity and Disaster Recovery Policy
• Acceptable Use Policy
• Human Resources Security Policy (covering onboarding, offboarding, background checks)

What makes a good policy: It should be specific enough to be actionable, realistic enough to be followed, and reviewed at least annually. Policies that say “we use industry best practices” are useless — state what you actually do.

Read our detailed guide: SOC 2 Policies and Procedures Guide

Implement Security Controls Aligned with Common Criteria

Controls are the operational mechanisms that enforce your policies. For SOC 2, these controls need to map back to the Common Criteria and any additional Trust Service Criteria you’ve included.

Key control areas for SaaS companies:

• Logical access controls: SSO with MFA for all production systems, role-based access, quarterly access reviews, automated deprovisioning on termination
• Network security: Firewall rules, network segmentation, intrusion detection/prevention, DDoS protection, VPN or zero-trust access for internal tools
• Change management: Pull request reviews, automated testing in CI/CD, deployment approval workflows, rollback procedures
• Data protection: Encryption at rest (AES-256) and in transit (TLS 1.2+), key management, data classification, secure deletion
• Monitoring and alerting: Centralized logging, SIEM or log aggregation, alerting on security events, log retention for the audit period

Set Up a Vendor Management Program

Your SOC 2 scope doesn’t end at your company’s boundary. Third-party services that process, store, or transmit data in scope for your report need to be assessed and monitored.

What to document for each vendor:

• What data they access or process
• Their SOC 2 report status (or equivalent security certifications)
• Contractual data protection terms
• Results of your risk assessment of the vendor
• Review cadence and last review date

SaaS example: Your application uses Stripe for payments, AWS for infrastructure, Datadog for monitoring, and Slack for internal communications. Stripe, AWS, and Datadog are in scope because they process or have access to customer data. Slack is likely out of scope unless it’s used to transmit customer data.

Establish Incident Response Procedures

Your incident response capability is one of the most scrutinized areas in a SOC 2 audit. Auditors want to see a documented plan, defined roles, clear escalation paths, and evidence that you’ve tested the plan.

Your incident response plan should cover:

• Incident classification and severity levels
• Detection and alerting mechanisms
• Response team roles and contact information
• Containment, eradication, and recovery procedures
• Communication protocols (internal, customer-facing, regulatory)
• Post-incident review process
• Evidence preservation requirements

In practice: When a security alert fires at 2 AM, your on-call engineer should know exactly where the runbook lives, who to escalate to, what decisions they’re authorized to make, and how to document their actions. If your incident response plan only works during business hours, it doesn’t work.

Phase 4: Evidence Collection and Monitoring

Controls without evidence are controls your auditor can’t verify. This phase is about proving — systematically and continuously — that your controls are operating as designed.

Set Up Evidence Collection Processes

SOC 2 auditors need evidence that your controls operated effectively throughout the audit period (for Type II). This means you need to collect and retain evidence continuously, not gather it retroactively.

Evidence types your auditor will request:

• Configuration evidence: Screenshots or exports showing system configurations (MFA enabled, encryption settings, firewall rules, access control lists)
• Process evidence: Records of access reviews, change approvals, incident responses, vendor assessments
• Automated evidence: Logs from SIEM, cloud provider audit trails, CI/CD pipeline records, deployment logs
• Human evidence: Training completion records, policy acknowledgments, background check confirmations

SaaS example: Your auditor asks for evidence that all production changes go through code review. Instead of scrambling to pull GitHub PR data, your compliance platform automatically captures pull request metadata — reviewer, approval timestamp, merge timestamp — and stores it as audit-ready evidence.

Read our detailed guide: SOC 2 Evidence Collection Guide

Implement Continuous Monitoring

Continuous monitoring means your controls are being validated on an ongoing basis — not just during audit prep. This catches control failures early and gives you time to remediate before the auditor arrives.

What to monitor continuously:

• Access control effectiveness (are terminated employees actually deprovisioned?)
• Configuration drift (did someone disable MFA on a service account?)
• Vulnerability management (are critical patches applied within your SLA?)
• Availability metrics (are you meeting your uptime commitments?)
• Change management adherence (are all production changes going through the defined process?)

Read our implementation guide: SOC 2 Continuous Monitoring Guide

Conduct Internal Readiness Assessment

Before engaging your auditor, run an internal readiness assessment. Walk through each control, verify that evidence exists, and identify any remaining gaps.

In practice: Assign a control owner for each SOC 2 control. Have each owner verify that their control is operating, evidence is being collected, and documentation is current. Any gaps discovered now are gaps you can fix before the audit clock starts.

Phase 5: The Audit

The audit itself is a structured engagement with your CPA firm. Preparation determines whether it’s a smooth process or a stressful scramble.

Prepare for the Audit Process

Your auditor will begin with a planning phase — understanding your system, reviewing your system description, and identifying the controls they’ll test. Come prepared with a clean, organized evidence repository and designated points of contact for each control area.

Preparation checklist:

• System description document (describing your service, infrastructure, and control environment)
• Complete list of controls mapped to SOC 2 criteria
• Evidence repository organized by control
• Designated contacts for each control domain
• Calendar availability for auditor walkthroughs

Support Auditor Walkthroughs and Testing

During the audit, the auditor will test your controls through a combination of inquiry (asking your team how things work), observation (watching processes in action), inspection (reviewing evidence and documentation), and reperformance (re-executing a control to verify it works).

SaaS example: The auditor tests your access control by selecting a sample of terminated employees and verifying their access was revoked within the timeframe specified in your policy. They’ll check Active Directory, AWS IAM, GitHub, and any other systems where those employees had access.

Address Any Findings

If the auditor identifies control deficiencies, you’ll have an opportunity to discuss them. Minor issues may be noted as observations in the report without affecting the opinion. Significant deficiencies or material weaknesses can result in a qualified opinion — which defeats the purpose of the report.

In practice: If the auditor finds that 2 out of 25 sampled access reviews were completed late, that’s likely an observation. If they find that 15 out of 25 were never completed, that’s a significant deficiency. The difference between these outcomes is the rigor of your ongoing compliance program.

Receive Your SOC 2 Report

The final deliverable is a SOC 2 report containing the auditor’s opinion, your system description, a description of your controls, the results of the auditor’s testing, and any noted exceptions. This report is what you share with customers and prospects under NDA.

Phase 6: Ongoing Compliance

A SOC 2 report has a shelf life. Enterprise customers expect current reports, and your controls need to operate continuously — not just during the audit window.

Maintain Continuous Monitoring

The controls you implemented for the audit need to keep running. Monitoring dashboards, automated evidence collection, and regular reviews should operate as part of your normal operations, not as audit-season activities.

Annual Re-Certification

Type II reports are typically issued annually. Your audit period should cover the 12 months since your last report, with no gaps. Start planning each audit cycle 2-3 months before the observation period ends to ensure smooth transitions.

Timeline tip: If your first Type II report covers January through June, your next report should cover July through June of the following year. Gaps between observation periods raise questions from customers reviewing your report.

Handle Changes

SaaS companies change constantly — new vendors, new infrastructure, new team members, new features. Each change can affect your SOC 2 control environment.

Changes that require reassessment:

• Adding a new third-party vendor that processes in-scope data
• Migrating to a new cloud provider or region
• Significant changes to your application architecture
• Organizational changes (acquisitions, restructuring, key personnel departures)
• New regulatory requirements from customers or markets
• Expanding into verticals with specific compliance needs (healthcare, finance)

Build a lightweight change assessment process: when a material change occurs, evaluate its impact on your SOC 2 controls and update your documentation accordingly. Your auditor will ask about significant changes during the next audit, and having documented assessments shows maturity.

Common Mistakes SaaS Teams Make

Starting too late. The number one mistake is beginning SOC 2 preparation 3 months before you need the report. A Type II report requires a 6-12 month observation period. Factor in 2-4 months of preparation before that period starts. If a customer needs your SOC 2 report next year, start now.

Treating compliance as the security team’s problem. SOC 2 touches engineering (change management, access controls, code review), HR (onboarding, offboarding, background checks), and operations (vendor management, business continuity). Every team that operates a control is responsible for that control.

Collecting evidence manually. Spending 40 hours pulling screenshots and exporting logs before each audit is a sign your evidence collection isn’t automated. Invest in tooling that captures evidence continuously — it pays for itself in the first audit cycle.

Writing policies nobody follows. Auditors test whether your team actually follows documented policies. A 30-page Information Security Policy that no engineer has read is worse than a 3-page policy that reflects what your team actually does. Write policies that describe real practices, then enforce them.

Ignoring vendor compliance. If a critical vendor doesn’t have their own SOC 2 report, your auditor will want to see how you assessed and manage that risk. “We trust them because they’re a big company” isn’t a risk assessment.
