What Is SOC 2? A Complete Guide to SOC 2 Compliance
Quick Answer
SOC 2 is a security framework developed by the AICPA that defines criteria for managing customer data based on five Trust Services Criteria: security, availability, processing integrity, confidentiality, and privacy.
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) that evaluates how service organizations manage customer data. Unlike prescriptive frameworks that tell you exactly what to do, SOC 2 is criteria-based — it defines what you need to achieve but gives you flexibility in how you achieve it.
Key Takeaways
- SOC 2 is an attestation (not a certification) — a CPA firm issues an opinion on your controls
- It covers five Trust Services Criteria: Security, Availability, Processing Integrity, Confidentiality, and Privacy
- Only Security (Common Criteria) is mandatory; the other four are optional based on your services
- SOC 2 Type I evaluates control design at a point in time; Type II tests operating effectiveness over 3-12 months
- Most B2B SaaS companies need SOC 2 to close enterprise deals — 85% of enterprise buyers require it
Who Needs SOC 2?
Any company that stores, processes, or transmits customer data should consider SOC 2 compliance. In practice, it's become table stakes for B2B SaaS companies, cloud service providers, managed service providers (MSPs), and data processing firms. If your customers are asking for a SOC 2 report — and they will once you start selling to mid-market or enterprise — you need SOC 2.
- SaaS companies selling to enterprise customers
- Cloud infrastructure and hosting providers
- Managed IT service providers (MSPs/MSSPs)
- Data analytics and processing companies
- Fintech companies handling financial data
- Healthcare technology companies (often alongside HIPAA)
- Any B2B company handling sensitive customer information
The Five Trust Services Criteria
SOC 2 is built around five Trust Services Criteria (TSC). Only Security (Common Criteria) is required for every SOC 2 audit. The other four are optional and should be included based on the services you provide and what your customers expect.
| Criterion | Focus | When to Include |
|---|---|---|
| Security (CC) | Protection against unauthorized access | Always required — foundational to every SOC 2 |
| Availability | System uptime and performance | If you offer SLAs or uptime guarantees |
| Processing Integrity | Data processing is complete and accurate | If you process transactions or critical data |
| Confidentiality | Protection of confidential information | If you handle trade secrets, IP, or NDA-protected data |
| Privacy | Collection, use, and disposal of personal info | If you collect and process personal data (PII) |
SOC 2 Type I vs Type II
There are two types of SOC 2 reports, and the distinction matters significantly for your timeline and credibility. For a deeper comparison, see our guide on SOC 2 Type I vs Type II.
SOC 2 Type I vs Type II
| Feature | Type I | Type II |
|---|---|---|
| What it tests | Control design at a point in time | Control operating effectiveness over time |
| Audit period | Single date (snapshot) | 3-12 months (typically 6-12) |
| Timeline to achieve | 1-3 months | 6-12 months |
| Cost range | $20,000-$60,000 | $30,000-$100,000+ |
| Customer acceptance | Acceptable for early-stage deals | Required by most enterprise buyers |
| Best for | Companies new to SOC 2 | Established companies, enterprise sales |
What Does the SOC 2 Process Look Like?
Typical SOC 2 Journey
Readiness Assessment (Weeks 1-4)
Evaluate your current security posture, identify gaps, and define your audit scope. Many companies engage a compliance automation tool or consultant at this stage.
Gap Remediation (Weeks 4-12)
Implement missing controls, write policies, configure monitoring, and deploy technical safeguards. This is usually the most time-intensive phase.
Type I Audit (Weeks 12-16)
A CPA firm reviews your controls at a single point in time and issues a Type I report. This can serve as an interim milestone while you prepare for Type II.
Observation Period (Months 4-10)
For Type II, your controls must operate effectively over a minimum of 3 months (most auditors prefer 6-12 months).
Type II Audit (Months 10-14)
The auditor tests your controls over the observation period, samples evidence, and issues the final Type II report.
How Much Does SOC 2 Cost?
Total SOC 2 costs vary significantly based on company size, complexity, and whether you use automation tools. For a detailed breakdown, see our guide on SOC 2 compliance costs.

SOC 2 vs Other Frameworks
SOC 2 is often compared to ISO 27001, HIPAA, and other security frameworks. Here's how it stacks up:
| Feature | SOC 2 | ISO 27001 | HIPAA | GDPR |
|---|---|---|---|---|
| Type | Attestation | Certification | Regulation | Regulation |
| Geographic focus | Primarily US | Global | US healthcare | EU/EEA |
| Who enforces it | Market-driven | Certification bodies | HHS/OCR | EU DPAs |
| Mandatory? | No (market-driven) | No (market-driven) | Yes (if applicable) | Yes (if applicable) |
| Audit frequency | Annual | 3-year cycle + surveillance | Risk-based | Ongoing |
| Best for | B2B SaaS | Global enterprises | Healthcare | EU data processing |
Common SOC 2 Myths
⚠️ Myth vs Reality
Myth: SOC 2 is a certification. Reality: It's an attestation — a CPA firm issues an opinion on your controls, not a pass/fail certificate.
Myth: You can fail a SOC 2 audit. Reality: The auditor issues a qualified or adverse opinion, but there's no formal pass/fail. However, a qualified opinion is effectively a failure in the eyes of customers.
Myth: SOC 2 is a one-time thing. Reality: You need to renew annually, and customers typically want a report that's less than 12 months old.
Getting Started with SOC 2
Your First Steps Toward SOC 2 Compliance
Assess your current state
Conduct a readiness assessment or gap analysis to understand where you stand. Many compliance tools offer free assessments.
Choose your Trust Services Criteria
Security (CC) is required. Add Availability, Confidentiality, Processing Integrity, and/or Privacy based on your service and customer requirements.
Select your approach
Decide whether to use a compliance automation platform, hire a consultant, or go DIY. For most companies, automation tools provide the best ROI.
Implement controls and policies
Address gaps identified in your assessment. Write required policies, implement technical controls, and train your team.
Choose an auditor
Select a CPA firm experienced in SOC 2 audits for your industry. Get proposals from 2-3 firms. See our guide on choosing a SOC 2 auditor.
Complete the audit
Start with Type I for quick wins, then progress to Type II for full enterprise credibility.
Is SOC 2 required by law?
No. SOC 2 is market-driven, not a legal requirement. However, it's effectively mandatory for B2B SaaS companies selling to enterprise customers — 85% of enterprise buyers won't sign a contract without a current SOC 2 report.
How long does a SOC 2 report stay valid?
SOC 2 reports don't technically expire, but customers and prospects typically want a report that's less than 12 months old. Most companies renew their SOC 2 annually.
Can I share my SOC 2 report publicly?
SOC 2 reports are restricted-use documents and should only be shared under NDA or with existing/prospective customers. If you want a public-facing report, consider adding a SOC 3 report (which is the same audit but summarized for general distribution).
Do I need SOC 2 if I use AWS or GCP?
Yes. Your cloud provider's SOC 2 report covers their infrastructure controls, but you're responsible for everything you build and configure on top of it — application security, access management, data handling, etc.
What's the difference between SOC 2 and ISO 27001?
SOC 2 is a US-focused attestation about controls; ISO 27001 is an international certification for an Information Security Management System (ISMS). Many global companies pursue both. See our detailed comparison at /learn/soc2/soc2-vs-iso27001.
