What is SOC 2 compliance, really?
SOC 2 (System and Organization Controls 2) is an auditing standard created by the American Institute of CPAs (AICPA) that evaluates how well your organization protects customer data. It is not a certification in the traditional sense — what you receive is an attestation report issued by an independent CPA firm confirming that your security controls meet the AICPA's Trust Services Criteria.
The framework is built around five Trust Services Criteria:
- Security — protection against unauthorized access. This is the only mandatory criterion and is required in every SOC 2 report.
- Availability — systems are operational and accessible as committed. Include this if you have uptime SLAs.
- Processing Integrity — data is processed accurately, completely, and on time.
- Confidentiality — sensitive information is protected from unauthorized disclosure.
- Privacy — personal data is collected, used, and retained in line with your privacy policy and applicable regulations.
Most SaaS companies start with Security only, then add Availability and Confidentiality as enterprise customers request them.
Important terminology: You'll hear people say "SOC 2 certified" but this is technically incorrect. SOC 2 is an attestation, not a certification. The distinction matters — a certification implies you passed a fixed bar, while an attestation means an independent auditor evaluated your specific controls and issued an opinion. The practical effect for closing enterprise deals is identical.
Do you actually need SOC 2?
SOC 2 is voluntary — no law requires it. But for B2B SaaS companies, it has become the de facto baseline that enterprise procurement teams expect. Here's a simple framework for deciding:
You almost certainly need SOC 2 if:
- You sell to enterprise or mid-market B2B customers in North America
- You handle sensitive customer data (PII, financial records, health data)
- Prospects are sending you lengthy security questionnaires before signing
- A deal has stalled or been lost because you couldn't provide a compliance report
- You're targeting regulated industries: finance, healthcare, government, or legal
You can probably wait if:
- You're pre-revenue or pre-product with no paying customers yet
- You sell exclusively to consumers (B2C), not businesses
- Your entire customer base is small businesses who've never asked about compliance
The timing trap: The most common mistake founders make is waiting until a major enterprise deal demands SOC 2 before starting. The minimum observation period for Type II is 3 months — a clock that cannot be accelerated regardless of budget. If you start when a deal demands it, you will lose that deal. Start before the demand arrives.
SOC 2 Type I vs Type II: which one first?
This is one of the most common questions — and the answer is almost always: start with Type I, immediately begin your Type II observation period.
SOC 2 Type I is a point-in-time assessment. An auditor evaluates whether your security controls are suitably designed as of a specific date. It can be achieved in as little as 45 days with high security maturity. It tells prospects: "our controls are correctly designed right now." It's useful for unblocking deals while your Type II observation period runs.
SOC 2 Type II evaluates whether those controls operated effectively over an observation period — typically 3 to 12 months. It tells prospects: "our controls have been consistently working over time." Enterprise customers almost universally require Type II. A Type I report alone will satisfy some prospects temporarily but is rarely accepted as a permanent substitute.
The playbook: Complete Type I to unblock immediate deals. Start your Type II observation period on the same day your Type I audit concludes. After 3–12 months, complete your Type II audit. Now you have the report enterprises actually require — and you haven't wasted any time.
The step-by-step SOC 2 process
Here is the exact process, in order. Don't skip steps — the most expensive mistakes in SOC 2 come from engaging an auditor before doing the groundwork.
Run a gap assessment
Before spending a dollar on an auditor, evaluate your current security controls against SOC 2's Trust Services Criteria. A gap assessment tells you exactly which controls are in place, which are partially implemented, and which are missing. This is the single highest-leverage step — it lets you budget accurately, prioritize remediation effort, and avoid discovering critical gaps mid-audit when it's expensive and embarrassing to fix them.
Define your scope
Decide which Trust Services Criteria to include (start with Security; add others based on what customers ask for). Define which systems, people, and processes are in scope. A narrower scope means a faster, cheaper audit — but don't scope so narrowly that customers question the report's relevance to your actual product.
Remediate your gaps
Work through the gaps your assessment identified. This typically involves writing or updating security policies, implementing technical controls (MFA, encryption, access reviews, vulnerability scanning, logging), building an incident response plan, and establishing vendor management processes. This is where most of the time and money goes — and why knowing your gaps upfront matters so much.
Implement evidence collection
SOC 2 auditors don't take your word for it — they want evidence that your controls are working. Set up systems to continuously capture audit evidence: access logs, system configuration screenshots, security training completion records, vulnerability scan results, change management tickets, and vendor assessments. The earlier you start collecting evidence, the longer and more credible your Type II observation period.
Choose your auditor
Only licensed CPA firms can conduct SOC 2 audits. Choose a firm that specializes in SOC 2 (not just any CPA), understands your industry and tech stack, and has experience with companies your size. Ask to meet the actual audit team — not just the sales team. Audit quality varies significantly between firms, and a poor-quality report reflects badly on you regardless of your controls.
Complete the Type I audit
Your auditor reviews your documentation, interviews key personnel, and tests whether your controls are suitably designed. This process typically takes 4–8 weeks. Be responsive to auditor requests — delays in providing evidence are the most common cause of extended timelines. At the end, you receive your Type I report.
Run your Type II observation period
Start immediately after Type I concludes. Your controls must operate consistently for 3–12 months. Keep collecting evidence continuously. Address any findings from the Type I report before your Type II audit begins. The longer your observation period, the more credible your report — but 3–6 months is sufficient for most enterprise customers.
Complete the Type II audit and maintain
Your auditor tests the operating effectiveness of controls over the observation period. This is more intensive than Type I — they're looking at evidence across the full period, not just a snapshot. Once complete, you have your Type II report. Plan to repeat the audit annually to keep the report current; most enterprise customers expect a report dated within the last 12 months.

Realistic SOC 2 timelines
Here is an honest breakdown of how long each phase takes, based on typical experience across companies of different maturity levels.
Gap assessment & scoping — 2 to 4 weeks
Running a gap assessment, defining scope, and building a remediation plan. Using a tool like Gap Assessment compresses this significantly — you can have your initial readiness score in under an hour.
Can start todayRemediation — 1 to 4 months
Implementing missing controls, writing policies, setting up evidence collection tooling. The range depends entirely on how many gaps you have. Companies with strong security maturity can compress this to 4–6 weeks. Starting from scratch may take 3–4 months.
Biggest variableType I audit — 4 to 8 weeks
Working with your auditor through fieldwork, walkthroughs, and the report drafting process. Having clean, organized evidence ready before the audit starts is the biggest factor in compressing this phase.
Unblocks dealsType II observation period — 3 to 12 months
The one phase that cannot be accelerated. Most companies run a 6-month observation period for their first Type II — it's credible enough for enterprise customers while getting you the report faster than a full year.
Cannot be rushedType II audit — 4 to 8 weeks
Similar timeline to Type I, but more evidence to review across the observation period. Companies with good evidence collection systems in place move through this phase faster.
Full enterprise credentialTotal time from standing start to Type II report: 9 to 18 months. Companies with strong existing security programs can hit the lower end. The most impactful thing you can do to compress this timeline is start your gap assessment today and begin remediation immediately — every week of delay adds directly to your total time.
What SOC 2 actually costs
SOC 2 costs vary widely based on your organization's size, complexity, and current security maturity. Here is a realistic breakdown for a typical early-stage to Series A SaaS company:
| Cost Category | Typical Range (Year 1) | Notes |
|---|---|---|
| Audit fees (Type I) | $10,000 – $25,000 | Varies by firm, company size, and scope |
| Audit fees (Type II) | $15,000 – $40,000 | Higher than Type I due to longer fieldwork |
| Compliance tooling | $5,000 – $20,000/yr | Automation platforms like Vanta, Drata, Secureframe |
| Readiness / consulting | $0 – $30,000 | Optional — tools reduce or eliminate this cost |
| Internal team time | 100 – 300 hours | Engineering, security, HR, and legal involvement |
| Total (Year 1) | $30,000 – $100,000 | Includes both Type I and Type II |
| Ongoing (Year 2+) | $20,000 – $50,000/yr | Annual Type II renewal + tooling |
The biggest driver of cost is how many gaps you need to remediate before your audit. A company with strong existing security controls might spend $30,000 total in year one. A company starting from scratch with minimal security documentation could spend $100,000+.
This is exactly why a thorough gap assessment before engaging an auditor is so valuable — it lets you understand your remediation cost before committing to an audit firm and timeline.
Cost reduction lever: Compliance automation platforms (Vanta, Drata, Secureframe, Sprinto) can reduce internal team time by 60–80% and eliminate most readiness consulting costs. For companies without a dedicated security team, the platform cost pays for itself in hours saved during the audit.
Common mistakes that delay the audit
After working with hundreds of companies through compliance assessments, these are the patterns that consistently add months and cost to the process:
- Skipping the gap assessment and going straight to an auditor. Discovering gaps during a paid audit engagement is expensive and embarrassing. Always assess before engaging.
- Scoping too broadly on the first audit. Including all five Trust Services Criteria when only Security is needed adds cost and time with minimal benefit. Add criteria as customers request them.
- Not starting evidence collection early enough. For Type II, evidence must span the full observation period. Starting evidence collection after you've already decided to pursue Type II means your observation period starts later.
- Choosing a generalist CPA firm. SOC 2 requires auditors who understand SaaS architecture, cloud environments, and modern DevOps. A traditional accounting firm without this expertise will slow down fieldwork and produce a lower-quality report.
- Treating it as a project, not a program. Controls that lapse between audits are flagged in your Type II report. SOC 2 requires consistent operation of controls year-round — not a sprint to audit-ready followed by a period of neglect.
- Underestimating vendor management. Your auditor will ask about third-party vendor risk. Many companies don't have a vendor inventory or assessment process in place, which adds unexpected work during fieldwork.
Where to start today
The single most valuable thing you can do right now — before choosing an auditor, before buying a compliance platform, before writing a single policy — is understand exactly where you stand.
A gap assessment maps your current security controls against SOC 2's Trust Services Criteria and tells you:
- Your current readiness score as a percentage
- Which control domains are fully present, partially implemented, or missing
- A prioritized list of exactly what needs to be fixed before you're audit-ready
- A realistic timeline and budget estimate based on your specific gaps
Without this information, you're guessing at timelines and costs. With it, you can make a fully informed decision about when to engage an auditor, how much remediation work to do yourself versus outsourcing, and whether to pursue SOC 2 alongside ISO 27001 to maximize the return on your compliance investment.
