A SOC 2 project becomes much easier when the team treats it as a sequence of operating decisions instead of a pile of auditor requests. This SOC 2 compliance checklist is designed for SaaS companies that need a practical path from “a customer asked for our report” to audit readiness without turning founders and engineers into full-time compliance staff.
SOC 2, short for System and Organization Controls 2, is an attestation framework used by service organizations. It uses the AICPA Trust Services Criteria, which require Security and may also include Availability, Confidentiality, Processing Integrity, and Privacy depending on the audit scope.
The checklist below focuses on the work that has to happen inside the company: scoping, security controls, control design, implementation, evidence collection, readiness assessment, the SOC 2 audit, and ongoing maintenance.
1. Decide What You Are Trying to Prove
Start with the customer requirement. Do they need a SOC 2 report now? Will a SOC 2 Type 1 report satisfy an immediate procurement gate, or are they expecting SOC 2 Type 2? Which product, infrastructure, people, and processes need to be in the audit scope?
Security is the required Trust Services Criteria category for SOC 2. Availability, confidentiality, processing integrity, and privacy may be added when they are relevant to customer commitments or the service being examined. Do not add criteria simply because they sound impressive; broader scope creates more control activities and evidence work.
Document the system boundary, the services included, third-party vendors that matter, major data flows, and any commitments you make to users. This becomes the basis for the control environment and the system description in the final SOC 2 report.
2. Run a Gap Assessment Before the Auditor Does
A readiness assessment compares your current program to the controls you need. A gap assessment or gap analysis should be specific enough to produce an implementation backlog, not a generic score.
Common gaps for SaaS startups include weak access management, incomplete offboarding, missing security awareness training, inconsistent change management, unclear incident response, insufficient audit logs, and policies that describe controls the company does not actually perform.
For technical areas, inspect the real environment. Check MFA, privileged access, logging, backup settings, data encryption, vulnerability management, endpoint controls, and alerting. For governance areas, check whether required reviews occur and whether evidence exists.
3. Build Controls Around How the Company Actually Works
SOC 2 controls should be executable. If a policy says every production change is reviewed, make sure the development workflow actually requires review. If the policy says access reviews occur quarterly, assign an owner and calendar the review.
Your control set will likely cover:
- Access controls and access management: SSO, MFA, privileged access, joiner-mover-leaver processes, and periodic reviews.
- Change management: code review, testing, deployment approval, and separation of duties where appropriate.
- Risk management: a documented risk assessment, treatment decisions, and risk mitigation work.
- Incident response: an incident response plan, roles, communication paths, and a tabletop or test.
- Business continuity and disaster recovery: backups, restoration testing, a disaster recovery plan, and recovery expectations.
- Data security: data classification, encryption, retention, and secure handling.
- Monitoring: security alerts, audit logs, exceptions, and continuous monitoring where useful.
- People controls: background checks where appropriate, onboarding, policy acknowledgments, and security awareness training.
- Vendor controls: due diligence and monitoring for important third-party vendors.
Policy templates can save time, but they are not a substitute for designing controls that match the business.
4. Choose the Right Tooling Without Confusing the Tool With the Program
A compliance automation platform such as Vanta or Drata can connect to cloud, identity, code, endpoint, and HR systems to surface evidence and control status. In GRC workflows, automation is useful for repetitive collection and reminders.
But the platform cannot own the program. Someone still needs to decide whether a failed test is a real gap, update the control, coordinate remediation, and explain exceptions to the SOC 2 auditor.
Use the tool to reduce manual evidence collection, not to avoid control ownership.
5. Prepare Evidence Before the Observation Period
Evidence should show both that the control exists and, for a Type 2 report, that it operated over the audit period. Build an evidence matrix that lists each control, owner, frequency, source, reviewer, and expected artifact.
Examples include:
- screenshots or exports showing MFA and access settings;
- completed quarterly access reviews;
- change tickets and pull-request approvals;
- vulnerability scan and remediation records;
- incident response tabletop results;
- training completion records;
- vendor review records;
- risk register entries and approvals;
- backup and disaster recovery test results.
A strong evidence process also records failures. A clean audit trail is better than hiding a control exception and discovering it late.
6. Complete SOC 2 Readiness Before You Start the Audit
SOC 2 readiness is the point where the controls are designed, implemented, and capable of producing evidence. For a SOC 2 Type 1, the CPA firm examines the design of controls at a point in time. For a SOC 2 Type 2, the examiner also evaluates operating effectiveness over a period.
The labels Type 1 and Type 2 are commonly used in conversation, while the reports themselves are SOC 2 Type 1 and SOC 2 Type 2. A Type 2 report is usually more persuasive to enterprise buyers because it includes operating evidence over the observation period.
Before the audit begins, review every control against the applicable common criteria and points of focus in the current AICPA Trust Services Criteria. Confirm evidence sources, owners, and any open remediation.
7. Select a Qualified SOC 2 Auditor
A SOC 2 examination is performed by an independent CPA firm. Ask about the auditor’s SaaS experience, scope assumptions, communication model, audit timeline, and how they handle exceptions.
Do not treat the auditor as your implementation consultant. The auditor’s job is to evaluate the system and controls. Your internal team or compliance partner should own readiness, evidence, and remediation before evidence goes to the auditor.
This separation protects audit independence and avoids the “mystery auditor” problem where a company does not understand who is issuing its report or what the audit actually covers.
8. Manage the Audit Like a Project
During the SOC 2 audit, keep requests in one queue. Track who owns each response, what evidence was provided, questions from the auditor, and any follow-up.
For a Type 2 report, the observation period matters. Controls need to operate consistently throughout the period. A review that should happen quarterly but never occurs can create an exception even if everything else looks good.
If a control fails, document the facts, assess impact, remediate promptly, and preserve the audit trail. One issue does not automatically mean the entire report fails, but unmanaged issues create unnecessary risk.
9. Know Which Tasks Cannot Be Delegated
Even with an embedded compliance partner, a few items require company participation. Leaders may need to approve policies and risk decisions. Control owners may need to confirm business context. Engineering may need to authorize environment changes. People Operations may need to confirm workforce records. Management may need to participate in incident response or disaster recovery exercises.
The goal is to keep those tasks narrow. SCI’s model is designed around doing the implementation, coordination, evidence work, and audit preparation so the client team does not become the compliance project manager.
10. Maintain the Program After the SOC 2 Report Arrives
SOC 2 compliance is not a one-time project. Controls must continue to operate if you want the next Type 2 report to be straightforward.
Keep the evidence cadence running. Continue access reviews, risk assessment updates, vendor reviews, training, security testing, incident response exercises, and disaster recovery work. Monitor data breaches, system changes, and new regulatory requirements that could alter scope.
If the company also pursues ISO 27001, HIPAA, GDPR, or PCI DSS, reuse controls where the requirements overlap instead of building parallel programs.
A SOC 2 compliance checklist should reduce uncertainty, not create busywork. If the checklist is still consuming hundreds of internal hours, the problem is usually ownership rather than the framework itself. SCI’s Embedded Compliance service is built for SaaS teams that want the controls, evidence, engineering work, and audit coordination handled as an operating function instead of another project on the CTO’s backlog.
