If you work at a SaaS company or any B2B organization that handles customer data, you have probably encountered this situation: a prospective customer sends over a security questionnaire, and somewhere on page two, there it is — "Please provide your most recent SOC 2 report."
SOC 2 has become the de facto security standard for technology companies. According to a 2024 survey by Drata, 73% of enterprise buyers require SOC 2 compliance from their vendors before signing a contract. For growing companies, understanding what SOC 2 entails, how the audit process works, and what it takes to get certified is no longer optional knowledge — it is a business necessity.
This guide covers everything you need to know about SOC 2, written for people who are not compliance experts.
What Is SOC 2?
SOC 2 (System and Organization Controls 2) is an auditing framework developed by the American Institute of Certified Public Accountants (AICPA). It evaluates how an organization manages customer data based on five categories called Trust Services Criteria.
Unlike PCI DSS or HIPAA, which are mandated by law or regulation, SOC 2 is voluntary. No government agency requires it. But the market does. Enterprise customers, partners, and procurement teams treat a SOC 2 report as proof that your organization takes data security seriously.
A SOC 2 report is not a certification in the traditional sense — it is an independent auditor's opinion on whether your controls meet the Trust Services Criteria you selected. You do not "pass" or "fail" SOC 2. The auditor issues a report with an opinion that is either unqualified (clean — your controls are effective) or qualified (there are exceptions or deficiencies).
Why SOC 2 Matters for SaaS and B2B Companies
Sales velocity. Without a SOC 2 report, enterprise sales cycles stretch out as prospects conduct their own security assessments. A SOC 2 report replaces that friction with a standardized, auditor-verified document.
Customer trust. A SOC 2 report is not a marketing claim — it is a third-party audit conducted by a licensed CPA firm.
Operational maturity. The process forces organizations to formalize security practices that might otherwise exist informally. Incident response plans, access reviews, change management, and vendor risk assessments all get documented, tested, and monitored.
The Five Trust Services Criteria
SOC 2 is built around five Trust Services Criteria (TSC), sometimes called Trust Services Principles or Trust Services Categories. You do not have to include all five in your audit — Security is the only required criterion, and the others are optional depending on your business model.
1. Security (Required)
Security is the foundation of every SOC 2 audit and the only mandatory criterion. It covers protection against unauthorized access to systems and data. This includes both physical access (data centers, offices) and logical access (authentication, authorization, network security).
Key areas under Security include:
- Access controls — How you manage who can access what, including provisioning, deprovisioning, role-based access, and multi-factor authentication
- Network and infrastructure security — Firewalls, intrusion detection, encryption in transit and at rest, vulnerability management
- Change management — How code and infrastructure changes are reviewed, tested, approved, and deployed
- Incident response — Documented processes for identifying, responding to, and recovering from security events
- Risk assessment — Regular evaluation of threats and vulnerabilities to your environment
2. Availability
The Availability criterion addresses whether your systems are operational and accessible as agreed upon with customers. This is particularly relevant for SaaS companies that provide uptime commitments through service level agreements (SLAs).
Controls in this category typically cover:
- Uptime monitoring and alerting
- Disaster recovery and business continuity planning
- Capacity planning and performance monitoring
- Backup and restoration procedures
- Redundancy and failover mechanisms
If your customers rely on your platform for critical business operations and you make availability commitments, include this criterion.
3. Processing Integrity
Processing Integrity ensures that system processing is complete, valid, accurate, timely, and authorized. This criterion matters most for companies whose products perform calculations, transactions, or data transformations where errors could have material consequences.
Examples include payment processing platforms, financial reporting tools, data analytics products, and any system where customers depend on the accuracy of outputs.
If your product is primarily a collaboration tool or content management system, Processing Integrity may not be relevant to your audit scope.
4. Confidentiality
Confidentiality covers the protection of information designated as confidential — trade secrets, intellectual property, business plans, and financial data. It goes beyond Security to address how confidential information is identified, classified, stored, transmitted, and disposed of. Controls typically include data classification policies, encryption, access restrictions based on classification, secure disposal procedures, and NDAs.
5. Privacy
Privacy applies specifically to personal information — data that can identify an individual. It aligns with the AICPA's Generally Accepted Privacy Principles and covers the full lifecycle: collection, use, retention, disclosure, and disposal. This criterion is relevant if your product collects or processes personal information from end users, covering consent, notice, data minimization, and individual rights — topics that overlap with GDPR and CCPA.
Important distinction: Confidentiality protects information that organizations designate as confidential. Privacy protects information about identifiable individuals. A company could need both, one, or neither depending on the data it handles.
SOC 2 Type I vs. Type II
SOC 2 comes in two report types, and understanding the difference is critical for planning your compliance timeline.
Type I: Design at a Point in Time
A SOC 2 Type I report evaluates whether your controls are suitably designed as of a specific date. The auditor examines your policies, procedures, and technical configurations and determines whether they are capable of meeting the Trust Services Criteria — but does not test whether they actually worked over time.
Think of Type I as a snapshot. It answers the question: "As of October 15, 2025, did this organization have appropriate controls in place?"
When to pursue Type I:
- You need a SOC 2 report quickly to unblock a sales deal
- You are going through SOC 2 for the first time and want to validate your controls before committing to a longer audit
- Your customers or prospects will accept a Type I report (many will, especially for initial engagements)
Typical timeline: 1-3 months of preparation, followed by a 2-4 week audit.
Type II: Operating Effectiveness Over Time
A SOC 2 Type II report evaluates whether your controls operated effectively over a defined observation period, typically 3-12 months. The auditor does not just check that controls exist — they test evidence that the controls functioned as designed throughout the entire period.
For example, a Type I audit might confirm that you have an access review policy. A Type II audit would verify that access reviews actually happened on schedule during the observation window, with documented evidence for each review.
When to pursue Type II:
- You have already completed a Type I and are ready for the next step
- Your enterprise customers specifically require Type II (many do, especially in financial services and healthcare)
- You want to demonstrate sustained operational security, not just a one-time design review
Typical timeline: The observation period itself is 3-12 months (6 months is common for a first Type II), plus 4-8 weeks for the audit after the observation window closes.
The Typical Progression
Most organizations achieve Type I first, then transition to Type II. The Type I gives you a baseline report to share with customers while you build the operational track record needed for Type II. Some companies skip directly to Type II if they already have mature security practices, but this is the exception.
SOC 1 vs. SOC 2 vs. SOC 3: Understanding the Differences
The SOC framework includes three report types, and they serve different purposes. Confusing them is common.
SOC 1 focuses on controls relevant to financial reporting. If your service affects your customers' financial statements — payroll processing, payment handling, loan servicing — a SOC 1 may be what their auditors need. It is governed by SSAE 18 and primarily supports customers' own financial audits.
SOC 2 focuses on operational controls related to security, availability, processing integrity, confidentiality, and privacy. It is the most relevant report type for SaaS and technology companies.
SOC 3 covers the same criteria as SOC 2 but is designed for general public distribution. Unlike SOC 2 reports (shared only under NDA), SOC 3 reports can be published on your website and shared freely. The trade-off is detail — SOC 3 omits control descriptions and test results. Most organizations pursue SOC 2 and optionally request a SOC 3 from the same audit.
| Feature | SOC 1 | SOC 2 | SOC 3 |
|---|---|---|---|
| Focus | Financial reporting controls | Security and operational controls | Same as SOC 2 |
| Audience | Customer auditors | Customers, prospects (under NDA) | General public |
| Detail level | High | High | Summary only |
| Distribution | Restricted | Restricted | Unrestricted |
| Common for SaaS | Rarely | Almost always | Sometimes (alongside SOC 2) |
The SOC 2 Audit Process
The audit process has four distinct phases. Understanding each one helps you plan resources and set realistic timelines.
Phase 1: Readiness Assessment
Before engaging an auditor, most organizations conduct a readiness assessment — either internally or with a consultant — to evaluate their current state against SOC 2 requirements. This phase identifies gaps between your existing practices and what the audit will require.
A thorough readiness assessment covers:
- Scope definition — Which systems, services, and Trust Services Criteria will be included
- Control mapping — Identifying existing controls and mapping them to SOC 2 requirements
- Gap analysis — Documenting where controls are missing, insufficient, or undocumented
- Remediation plan — Prioritized list of gaps to address with timelines and owners
This phase typically takes 2-4 weeks and is one of the highest-value steps in the process. Skipping it almost always leads to surprises during the audit.
Phase 2: Gap Remediation
With gaps identified, the work begins. Remediation involves implementing missing controls, formalizing existing practices into documented policies, and deploying tools for evidence collection. Common activities include writing security policies, implementing technical controls (endpoint protection, logging, vulnerability scanning), setting up access management processes, establishing change management procedures, and training employees.
This is typically the longest phase, ranging from 1-6 months depending on your starting point. Organizations with existing security programs may need only minor adjustments. Startups building from scratch will need more time.
Phase 3: Audit Period
For Type I, the auditor examines your controls at a specific point in time. For Type II, you need to operate your controls throughout the observation period (typically 3-12 months) while collecting evidence that demonstrates they are working.
During the observation period for Type II, you should be:
- Conducting access reviews on schedule
- Completing vulnerability scans and remediating findings
- Processing change requests through your defined workflow
- Documenting and resolving security incidents
- Performing vendor risk assessments
- Running and testing backups
- Collecting evidence for all of the above
Phase 4: Audit and Report
The formal audit involves the CPA firm reviewing your controls, testing evidence, and issuing their report. The auditor provides a PBC (Prepared by Client) evidence list, conducts walkthroughs with key personnel, samples evidence from throughout the observation period (for Type II), drafts the report, and gives you an opportunity to respond to any identified exceptions.
The audit phase typically takes 4-8 weeks from evidence submission to final report.
Choosing Which Trust Services Criteria to Include
Selecting the right criteria is a strategic decision. Including too few may not satisfy customer requirements. Including too many increases scope, cost, and audit risk.
Start with your customers. Review security questionnaires you have received. If most focus on data security and uptime, Security and Availability are your priorities. If customers ask about data privacy or processing accuracy, consider Privacy or Processing Integrity.
Consider your product. A SaaS platform with 99.9% uptime SLAs should include Availability. A data analytics company should consider Processing Integrity. A platform handling consumer personal data should consider Privacy.
Think about future requirements. If you plan to move upmarket into regulated industries, those sectors often expect broader coverage. Starting with Security alone and adding criteria in subsequent audit cycles is a common approach.
For most B2B SaaS companies, Security plus Availability covers the majority of customer requirements.
Common Controls and Evidence Required
Understanding what auditors look for helps you prepare efficiently. These control categories appear in virtually every SOC 2 audit:
Access Management — User provisioning/deprovisioning procedures, quarterly access reviews, MFA enforcement, role-based access control, and unique user accounts (no shared credentials).
Change Management — Code review and approval workflows, deployment documentation, separation of duties between development and production, and change request records.
Risk Assessment — Annual risk assessment documentation, a risk register with threats and treatment plans, and board or management review of findings.
Security Operations — Centralized logging with 90+ day retention, intrusion detection alerts, vulnerability scanning results with remediation timelines, and endpoint protection records.
Incident Response — A documented incident response plan, evidence of tabletop exercises, incident logs showing detection through resolution, and post-incident reviews.
Vendor Management — Vendor inventory with risk classifications, due diligence records, vendor SOC 2 reports on file, and contractual security requirements.
Human Resources — Background checks, security awareness training records, signed acceptable use agreements, and onboarding/offboarding checklists.
Business Continuity — DR and business continuity plans, annual DR testing evidence, backup restoration testing, and documented recovery objectives.
How Long SOC 2 Takes and What It Typically Costs
Timeline Expectations
The total timeline from decision to report depends on your starting point:
Organizations with existing security programs (formal policies, centralized logging, access management already in place): 3-6 months to a Type I report, 6-12 months to a Type II report.
Organizations building from scratch (limited documentation, informal security practices): 6-12 months to a Type I report, 12-18 months to a Type II report.
These are general ranges. Companies using compliance automation platforms (Vanta, Drata, Secureframe, Sprinto, and others) often shorten the remediation phase significantly because these tools automate evidence collection and continuous monitoring.
Cost Components
SOC 2 costs fall into several categories, and total investment varies widely based on company size, complexity, and existing infrastructure.
Audit fees: CPA firms typically charge between $20,000 and $80,000 for a SOC 2 audit, depending on scope, company size, and the number of Trust Services Criteria included. Type II audits cost more than Type I due to the extended observation period and additional testing. Large, complex organizations may see fees exceed $100,000.
Compliance automation platforms: Most companies now use a compliance platform to streamline evidence collection and control monitoring. These typically cost $10,000-$50,000 per year depending on company size and features.
Remediation costs: The hardest category to estimate. It might include new security tools, infrastructure changes, consultant fees, and internal staff time. For a startup with limited existing controls, $50,000-$150,000 in the first year is not unusual.
Ongoing costs: SOC 2 is not a one-time event. Annual audits, tool subscriptions, and staff time for continuous compliance typically cost $50,000-$150,000 per year.
Total first-year investment for a mid-sized SaaS company typically ranges from $80,000 to $250,000. Subsequent years are lower because the heavy remediation lift is done.
Continuous Compliance vs. Point-in-Time Audits
One of the biggest shifts in SOC 2 has been the move from point-in-time compliance to continuous monitoring.
Historically, many organizations treated SOC 2 as an annual project. Controls would drift throughout the year, and teams would scramble before the audit window to fix issues and collect evidence. This approach is stressful, error-prone, and increasingly inadequate as auditors look for consistent evidence across the entire observation period.
Continuous compliance means your controls are monitored every day, not just during audit season. Compliance automation platforms make this practical by integrating with your cloud infrastructure, identity provider, version control, and HR tools to automatically collect evidence and flag control failures in real time.
The benefits are substantial:
- Fewer audit exceptions — control gaps are caught and fixed immediately, not discovered months later
- Lower audit costs — evidence is organized and readily available, reducing auditor time
- Reduced staff burden — manual evidence collection is replaced by automated monitoring
- Better actual security — vulnerabilities and misconfigurations are caught quickly, not just documented
For Type II audits, continuous compliance is particularly important. The auditor samples evidence throughout the observation period. If your access reviews were consistent for ten months but missed in months three and four, those gaps will appear in the report.
Common Mistakes That Delay SOC 2 Certification
Having seen many organizations go through the SOC 2 process, certain patterns consistently cause delays. Avoiding these mistakes can save months.
1. Scoping Too Broadly
Including all five Trust Services Criteria in your first audit when customers only require Security and Availability multiplies the work without proportional business benefit. Start narrow and expand in future audit cycles.
2. Writing Policies You Cannot Follow
Policies that describe practices your organization does not actually follow create audit exceptions. If your policy says monthly access reviews but you can only do quarterly, write the policy for quarterly. Honest, achievable policies that you follow consistently are better than aspirational ones you violate.
3. Underestimating Evidence Collection
Many organizations implement controls but fail to collect evidence that those controls are operating. An access review that happens but is not documented did not happen from the auditor's perspective. Build evidence collection into every control from the start.
4. Ignoring Vendor Management
Your SOC 2 scope includes third-party services your systems depend on. Auditors expect you to have assessed those vendors' security posture. At minimum, maintain a vendor inventory, collect their SOC 2 reports, and review them annually.
5. Treating It as an IT-Only Project
SOC 2 touches HR, legal, management, and operations. Treating it as something the engineering team handles alone leads to gaps in non-technical control areas.
6. Delaying the Readiness Assessment
Companies that skip the readiness assessment and go straight to the audit often discover significant gaps that force a pause. A readiness assessment costs far less than a delayed audit.
7. Not Assigning a Dedicated Owner
SOC 2 projects without a single accountable owner tend to stall. This does not have to be a full-time role, but someone needs to own it.
8. Choosing the Wrong Auditor
Not all CPA firms have the same experience with technology companies. Choose an auditor who understands cloud-native architectures, CI/CD pipelines, and infrastructure-as-code.
Using SOC 2 as a Competitive Advantage
Beyond risk reduction, SOC 2 creates tangible business advantages:
Accelerating sales cycles. A SOC 2 report replaces weeks of back-and-forth security questionnaires with a single, standardized document. Sales teams can share it proactively, removing security as an objection before it surfaces.
Enabling upmarket expansion. Financial services, healthcare, and government customers often will not evaluate vendors without SOC 2. Compliance opens these segments entirely.
Reducing customer security assessments. Without SOC 2, every customer conducts their own security evaluation. With it, you provide a standardized report that satisfies most requirements, reducing operational burden on your team.
Strengthening partnerships. Technology partnerships, reseller agreements, and marketplace listings (AWS Marketplace, Azure Marketplace) increasingly require SOC 2.
Building internal security culture. The discipline of SOC 2 creates lasting improvements in how your organization handles security. Employees become more security-conscious, processes become more reliable, and incident response becomes faster. These improvements compound over time, reducing actual risk — not just compliance risk.
Key Takeaways
SOC 2 is not just a checkbox — it is a structured approach to demonstrating that your organization manages customer data responsibly. Here is what to remember:
- Start with Security, the only required Trust Services Criterion, and add others based on customer requirements and business model
- Pursue Type I first if you need a report quickly, then transition to Type II for long-term credibility
- Invest in a readiness assessment before engaging an auditor to avoid costly surprises
- Write policies you can actually follow — auditors test operational reality, not aspirational documents
- Adopt continuous compliance practices rather than treating SOC 2 as an annual scramble
- Assign a dedicated owner to drive the project across engineering, HR, legal, and management
- Budget realistically — first-year costs typically range from $80,000 to $250,000 for mid-sized SaaS companies
- Choose an auditor with experience in your industry and technology stack
SOC 2 requires real investment, but for B2B and SaaS companies, it pays dividends in customer trust, sales velocity, and operational maturity. The organizations that treat it as a business enabler rather than a compliance burden are the ones that get the most value from the process.
