Introduction
Preparing for a SOC 2 audit can feel overwhelming, especially for growing companies that are doing it for the first time.
The audit touches security, engineering, operations, HR, IT, vendor management, policies, access control, incident response, and customer trust. It also requires evidence. Not just evidence that controls exist today, but evidence that controls are operating as expected during the audit period.
The biggest mistake companies make is treating SOC 2 preparation as a one time project.
A better approach is to treat SOC 2 readiness as an operating system for trust. That means defining your scope, understanding your controls, collecting evidence over time, assigning ownership, and reviewing gaps before the auditor asks for proof.
This guide walks through the major steps companies should take when preparing for a SOC 2 audit.
What Is a SOC 2 Audit?
A SOC 2 audit is an independent examination of a service organization’s controls related to security, availability, processing integrity, confidentiality, and privacy.
SOC 2 is commonly used by SaaS companies, software vendors, cloud platforms, technology service providers, and other companies that handle customer data or operate systems that customers depend on.
The audit helps customers and stakeholders understand whether the company has appropriate controls in place to protect systems, data, and business operations.
SOC 2 does not work like a simple checklist. The auditor evaluates whether the company’s controls are designed appropriately and, for a Type 2 report, whether those controls operated effectively over a defined period of time.
Step 1: Understand Why You Need SOC 2
Before starting the audit process, clarify why your company needs SOC 2.
Common reasons include:
- Enterprise customers are asking for a SOC 2 report.
- Security questionnaires are slowing down sales.
- Procurement teams require independent assurance.
- Investors or partners want stronger governance.
- The company wants to improve its security posture.
- Leadership wants a repeatable compliance program.
The reason matters because it affects timing, scope, and urgency.
For example, if a major customer requires a SOC 2 Type 2 report before signing, your timeline may be more aggressive. If you are preparing proactively, you may have more time to mature your controls before the audit period begins.
Step 2: Decide Between SOC 2 Type 1 and Type 2
SOC 2 Type 1 and SOC 2 Type 2 reports answer different questions.
A SOC 2 Type 1 report evaluates whether controls are designed appropriately at a specific point in time.
A SOC 2 Type 2 report evaluates whether controls are designed appropriately and operating effectively over a defined period of time.
In simple terms:
SOC 2 Type 1 asks, “Are the controls set up properly?”
SOC 2 Type 2 asks, “Did the controls work over time?”
Many companies start with Type 1 if they need an initial milestone or want an auditor to review control design before moving into a longer Type 2 period.
Other companies go directly to Type 2 if customers require it and the company already has enough evidence to support control operation over time.
Before choosing, ask:
- What are customers asking for?
- How mature are our controls?
- Do we have evidence from the audit period?
- Can we sustain the audit process operationally?
- Are we ready to prove control operation over time?
Step 3: Define the Audit Scope
Scope is one of the most important parts of SOC 2 preparation.
Your scope determines which systems, processes, teams, products, data flows, and trust services categories are included in the audit.
A clear scope helps avoid confusion and reduces unnecessary work.
Common scope questions include:
- Which product or service is being audited?
- Which production systems support that product?
- Which cloud environments are included?
- Which databases store customer data?
- Which teams manage the in-scope systems?
- Which third party vendors support the service?
- Which customer data types are involved?
- Which Trust Services Criteria apply?
- Which locations, tools, and processes are relevant?
Many companies start with security as the core category. Other categories such as availability, confidentiality, processing integrity, or privacy may be added depending on customer expectations, contracts, system responsibilities, and business needs.
Step 4: Document Your Systems and Data Flows
Before you can audit controls, you need to understand the environment.
This usually includes documenting:
- Production systems
- Cloud infrastructure
- Databases
- Internal tools
- Identity providers
- CI/CD pipelines
- Monitoring tools
- Logging systems
- Customer data flows
- Vendor dependencies
- Administrative access paths
This documentation helps auditors understand how your system works and where controls apply.
It also helps your internal team identify risk areas. For example, if customer data flows through several systems, each of those systems may require access controls, monitoring, vendor review, and evidence retention.
Step 5: Identify Your Controls
Controls are the processes, safeguards, and requirements your company uses to manage risk.
Examples include:
- Access to production systems must be approved before being granted.
- Administrative access must be reviewed quarterly.
- Terminated users must be removed from key systems.
- Production code changes must be reviewed before deployment.
- Security incidents must be tracked and resolved.
- Vendors must be reviewed before approval.
- Employees must complete security awareness training.
- Policies must be reviewed and approved annually.
- Backups must be configured and monitored.
- Vulnerabilities must be reviewed and remediated based on severity.
Each control should be written clearly enough that someone can understand what activity is required, who owns it, how often it happens, and what evidence proves it happened.
Step 6: Assign Control Owners
SOC 2 preparation fails when ownership is unclear.
Every control should have an owner. The owner does not need to do every task personally, but they should be accountable for making sure the control operates and evidence is available.
Common control owners include:
- Engineering
- Security
- IT
- HR
- Operations
- Finance
- Legal
- Compliance
- Executive leadership
For example:
- Engineering may own code review and deployment controls.
- IT may own access provisioning and device management.
- HR may own onboarding, offboarding, and training records.
- Security may own vulnerability management and incident response.
- Operations may own vendor reviews and business continuity records.
- Leadership may own risk management and policy approval.
Clear ownership reduces confusion when evidence is needed.
Step 7: Map Evidence to Controls
Evidence is the proof that controls are operating.
For SOC 2, evidence may include:
- Screenshots
- Tickets
- Logs
- Approvals
- Policies
- Training records
- Access reviews
- Pull request approvals
- Deployment history
- Security alerts
- Vendor reviews
- Incident records
- Cloud configuration exports
- Monitoring reports
- Meeting notes
- Risk assessments
The important part is not just collecting evidence. The important part is mapping evidence to the control it supports.
For example:
- Pull request approvals support change management controls.
- Okta exports support access control reviews.
- Jira tickets support access approvals, incidents, and change history.
- AWS configuration exports support infrastructure and security controls.
- Training completion reports support security awareness controls.
- Vendor SOC 2 reports support vendor management controls.
Evidence should be organized by control, source system, owner, and time period.
Step 8: Review Gaps Before the Audit
A readiness review helps identify gaps before the formal audit begins.
Common gaps include:
- Missing policies
- Incomplete access reviews
- Lack of evidence for approvals
- Unclear control ownership
- Inconsistent ticketing
- Missing vendor reviews
- Untracked exceptions
- Weak offboarding records
- Expired logs
- Informal change management
- Missing incident response testing
- Policies that were written but never acknowledged
The goal of a readiness review is not to punish the team. The goal is to identify what needs to be fixed before evidence is tested.
The earlier you find gaps, the easier they are to address.
Step 9: Build a Policy Set
Policies explain how the company manages security, compliance, risk, and operations.
Common SOC 2 related policies include:
- Information security policy
- Access control policy
- Change management policy
- Incident response policy
- Vendor management policy
- Risk management policy
- Business continuity policy
- Disaster recovery policy
- Acceptable use policy
- Data classification policy
- Encryption policy
- Vulnerability management policy
- Security awareness training policy
Policies should be practical. They should reflect how the company actually operates.
A policy that looks mature on paper but does not match real workflows can create audit problems. If a policy says access reviews happen monthly, but the company only performs them quarterly, the policy and control process are misaligned.
Step 10: Prepare Access Control Evidence
Access control is usually one of the most important areas in SOC 2.
Companies should be ready to show:
- Who has access to key systems
- Who has administrative privileges
- How access is requested
- How access is approved
- When access is granted
- How access is reviewed
- How access is removed
- How terminated users are deprovisioned
- Whether MFA is enabled
- Whether privileged access is limited
Access evidence often comes from identity providers, application admin panels, HR systems, ticketing systems, and access review records.
The best practice is to preserve evidence when the access activity happens, not months later.
Step 11: Prepare Change Management Evidence
For software companies, change management evidence is critical.
Auditors often want to understand how code changes move from development to production.
Companies should be ready to show:
- Code changes are reviewed before deployment.
- Pull requests are approved.
- Changes are linked to tickets or business reasons.
- Testing or validation occurs before release.
- Deployments are tracked.
- Emergency changes are documented.
- Failed deployments or rollbacks are reviewed.
- Production access is controlled.
Useful evidence may include pull request records, code review approvals, deployment logs, CI/CD results, release notes, and Jira tickets.
Step 12: Prepare Security Monitoring Evidence
Security monitoring evidence shows that the company detects, reviews, and responds to risks.
Companies should be ready to show:
- Security tools are active.
- Alerts are reviewed.
- Vulnerabilities are scanned.
- Findings are assigned and tracked.
- Patches are applied based on severity.
- Incidents are documented.
- Monitoring and logging are configured.
- Exceptions are reviewed.
Useful evidence may include vulnerability scan reports, security alert records, patch management tickets, incident tickets, endpoint protection reports, cloud findings, and monitoring dashboards.
Step 13: Prepare Vendor Management Evidence
SOC 2 preparation should include third party vendors that support in-scope systems or handle sensitive data.
Companies should be ready to show:
- A vendor inventory
- Vendor owners
- Vendor risk ratings
- Security reviews
- Contract or approval records
- SOC 2 reports from key vendors
- Data processing agreements when applicable
- Renewal reviews
- Risk acceptance documentation
Vendor evidence helps show that third party risk is being identified and managed.
Step 14: Prepare Training and Policy Evidence
Auditors may ask whether employees are trained on security expectations and whether policies are communicated.
Companies should be ready to show:
- Security training assignments
- Training completion reports
- Employee acknowledgement records
- Policy approval dates
- Policy review history
- New hire onboarding records
- Confidentiality agreements
- Acceptable use acknowledgements
This evidence shows that security and compliance expectations are not only written down, but communicated to the workforce.
Step 15: Prepare Incident Response Evidence
Even if the company did not have a major incident, it should still be ready to show an incident response process.
Evidence may include:
- Incident response policy
- Incident severity definitions
- Incident ticket examples
- Escalation procedures
- Postmortem templates
- Tabletop exercise records
- Remediation records
- Communication plans
- Lessons learned documentation
The goal is to show that the company has a defined process for identifying, escalating, resolving, and learning from incidents.
Step 16: Organize Evidence by Audit Period
For SOC 2 Type 2, timing matters.
Evidence should support the full audit period. If the audit period is six months, the company needs evidence from across those six months.
For example:
- Access reviews should align with the required review cadence.
- Code review evidence should show activity throughout the period.
- Security monitoring evidence should show ongoing review.
- Vendor evidence should reflect relevant review dates.
- Policy evidence should show approval and acknowledgement timing.
- Incidents and exceptions should be tracked when they occur.
A strong evidence program makes it easy to filter records by date range, control, system, and owner.
Step 17: Avoid Common SOC 2 Preparation Mistakes
Many SOC 2 issues come from predictable mistakes.
Waiting Too Long
If preparation starts only when the auditor asks for evidence, the team may discover missing records too late.
Over-Relying on Screenshots
Screenshots can be useful, but they often lack context. Stronger evidence includes timestamps, owners, approvals, logs, tickets, and source system history.
Writing Policies That Do Not Match Reality
Policies should describe real operating practices. If the company cannot follow the policy, the policy should be revised or the process should be improved.
Leaving Engineering Out Until the End
Engineering often owns key evidence for code review, deployments, infrastructure, monitoring, and access. Involving engineering early reduces audit friction.
Not Tracking Exceptions
Exceptions are not automatically failures. However, they need to be documented, reviewed, and resolved.
Not Mapping Evidence to Controls
A folder of files is not the same as an audit ready evidence system. Evidence should be tied to controls, time periods, systems, and owners.
Step 18: Move From Audit Prep to Continuous Readiness
The best SOC 2 preparation strategy is to stop treating compliance as a last minute event.
Audit readiness should become part of normal operations.
That means:
- Collecting evidence as work happens
- Reviewing access on schedule
- Preserving code review and deployment history
- Tracking vendor reviews
- Maintaining policies
- Reviewing security findings
- Documenting incidents
- Mapping evidence to controls
- Keeping control owners accountable
This turns SOC 2 from a scramble into a manageable process.

Final Thoughts
Preparing for a SOC 2 audit is not just about passing an audit. It is about building a repeatable trust program.
The companies that prepare well do not wait until the auditor arrives. They define scope early, assign owners, document controls, collect evidence over time, review gaps, and make compliance part of normal business operations.
SOC 2 preparation becomes much easier when the company can answer one simple question:
Can we prove our controls worked during the audit period?
If the answer is yes, the audit process becomes far more manageable.
FAQ
How long does it take to prepare for a SOC 2 audit?
The timeline depends on the company’s size, scope, control maturity, evidence quality, and whether it is pursuing Type 1 or Type 2. Companies with mature controls and organized evidence can usually move faster than companies starting from scratch.
What should we do first when preparing for SOC 2?
Start by defining the audit scope, identifying the systems involved, selecting the relevant Trust Services Criteria, and documenting the controls that apply to your environment.
What evidence is needed for a SOC 2 audit?
Common evidence includes access reviews, approval tickets, pull request approvals, deployment logs, policies, training records, vendor reviews, incident records, vulnerability scans, cloud configuration exports, and monitoring records.
Do we need SOC 2 Type 1 before SOC 2 Type 2?
Not always. Some companies start with Type 1 as an initial milestone, while others go directly to Type 2 if their controls are already operating and they have evidence across the audit period.
Who should own SOC 2 preparation?
SOC 2 preparation usually needs a central owner, often security, compliance, operations, or leadership. However, evidence ownership is cross-functional and may include engineering, IT, HR, finance, legal, and operations.
What is the biggest SOC 2 preparation mistake?
The biggest mistake is waiting until audit time to collect evidence. Evidence is strongest when it is captured close to the activity and organized continuously throughout the audit period.
