What Is SOC 2? A Simple Guide for Businesses

SOC 2 is a type of independent audit that examines how a service company protects customer information. The company receives a report describing what was checked and the auditor's findings. Customers can use that report when deciding whether to trust the company with their data.

The audit is performed by a licensed CPA firm against standards set by the American Institute of Certified Public Accountants (AICPA). SOC 2 isn't a government certification or a pass/fail badge, it's a professional attestation.

A situation this actually solves: a payroll software company wants to sell to a larger business. The buyer asks how employees' salary information is protected. A SOC 2 report helps the buyer assess the provider's security measures. The auditor might examine who can access that information, and how access is removed when an employee leaves.

So, what is SOC 2, in plain terms? Independent proof that a company's security claims hold up, not just a policy document nobody's tested.

Who Asks for a SOC 2 Report, and Why

SOC 2 applies to service organizations that store, process, or transmit customer data. SaaS companies, cloud service providers, data centers, managed IT providers, HR platforms, and similar technology businesses. SOC 2 for SaaS companies in particular has become close to table stakes in enterprise sales. It's rare to get past procurement without one.

It isn't a legal requirement like HIPAA or GDPR, but it's become a commercial one. Large organizations routinely require a current SOC 2 report as part of vendor assessment, and deals are frequently paused until one is provided. Beyond closing deals, preparing for SOC 2 forces a company to document controls, close gaps, and build security habits that hold up over time, not just on the day of the audit.

The Five Areas SOC 2 Can Cover

An auditor evaluates against up to five Trust Services Criteria. Security is the only mandatory one; the rest are included based on what's relevant to the services a company provides.

• Security (mandatory). Protects against unauthorized access, misuse, and breaches. Example: multi-factor authentication on admin accounts.
• Availability. Covers whether systems are accessible as promised. Example: a tested disaster-recovery plan, not just a backup that's never been restored.
• Processing integrity. Covers whether the system processes data completely and accurately. Relevant to payment processors and similar systems where "did this transaction go through correctly" matters.
• Confidentiality. Covers whether data marked confidential stays that way throughout its lifecycle, through encryption and access restrictions.
• Privacy. Covers how personal information is collected, used, retained, and disposed of. Relevant to anyone handling PII or sensitive personal data.

See our full breakdown of the SOC 2 Trust Services Criteria for how each one maps to real controls.

SOC 2 Report Types: Type 1 vs Type 2

Understanding SOC 2 Type 1 vs Type 2 comes down to one question: does the report look at a single date, or a period of time?

A common misconception is that Type 2 always requires a fixed six-month minimum. It doesn't. The AICPA doesn't set a universal minimum reporting period. First-time Type 2 reports are sometimes as short as three months, with the exact period, and what work happens during it, agreed between the company and its auditor. What matters isn't a specific number of months, it's whether the period is long enough for the auditor to actually observe the controls operating.

Most enterprise customers ask for Type 2 specifically because it shows controls working over time, not just existing on paper for one day. Which report you need depends on what your buyers are actually asking for. Some accept Type 1 as an interim step, others want Type 2 from the start.

What's Actually in a SOC 2 Report

SOC 2 report contents aren't a simple pass/fail slip. The report contains several parts: management's assertion (the company's own statement that its controls operate as described), the auditor's opinion on whether that assertion holds up, a description of the system in scope, and the results of the auditor's testing, including any exceptions found.

The auditor's opinion falls into one of four categories:

• Unqualified (full conformity). Controls are suitably designed and, for Type 2, operated effectively. No material exceptions.
• Qualified (partial conformity). One or more exceptions were found, but the overall control environment is still adequate.
• Adverse (non-conformity). Controls are not suitably designed or not operating effectively.
• Disclaimer of opinion (conformity status not determined). The auditor didn't have enough information to reach a conclusion.

A buyer reviewing your report should look at more than just the headline opinion. The system description and any noted exceptions tell them what was actually tested and what, if anything, needs follow-up. SOC 2 reports are confidential and typically shared under NDA or through a secure portal, not published publicly.

How a SOC 2 Audit Works

Only a CPA firm licensed by a U.S. state board of accountancy, independent of your organization, can issue a valid report. An auditor who also built your controls can't sign off on them. See our top SOC 2 auditors if you're choosing one.

The process itself, briefly:

1. Scoping. Deciding which systems and which of the five criteria apply.
2. Readiness assessment (optional, recommended). Checking controls against the criteria before the real audit, so gaps get fixed while they're still cheap to fix.
3. The observation period (Type 2 only). Controls run and get evidenced over the agreed period.
4. Examination. The auditor tests controls through document review, interviews, and technical checks.
5. Reporting. The report is issued, typically a few weeks to two months after the period ends.
6. Annual renewal. Most companies repeat this yearly, since reports are time-bound.

Here's a SOC 2 audit example with real records, not just a category list:

For the full walkthrough, including report-section detail and what happens after you receive your report, see our SOC 2 audit process guide. Before the audit itself, most teams work through a SOC 2 readiness checklist covering access, HR, infrastructure, change management, and vendor management.

What Affects the Time and Cost

How much does SOC 2 cost? There's no single number, but here are the ranges that matter. Audit fees typically range from $5,000 to $50,000, and total compliance cost, including readiness work, remediation, tooling, and internal time, typically lands between $10,000 and $100,000 for a first Type 2 certification, based on company size. These are broad ranges; the actual number depends heavily on scope, how mature your controls already are, and which auditor you choose.

Timeline-wise, a Type 1 audit usually takes two to three months end to end. A first Type 2 audit is typically closer to nine to twelve months once you count the observation period, though this varies with the period length agreed with your auditor.

How SOC 2 Compares to SOC 1, SOC 3, and ISO 27001

SOC 1 vs SOC 2 vs SOC 3. All three come from the AICPA, but answer different questions. SOC 1 covers controls relevant to a customer's financial reporting. SOC 2 covers the security-related criteria above and is shared under NDA. SOC 3 covers the same ground as SOC 2 but is a summarized, public-facing version anyone can read. If SOC 1 might be relevant to your business, see our SOC 1 vs SOC 2 comparison.

SOC 2 vs ISO 27001. SOC 2 is a U.S.-issued attestation, most recognized in North American procurement. ISO 27001 is an international certification, more widely recognized in Europe and Asia Pacific, built around implementing a full Information Security Management System against 93 reference controls (the standard was revised down from 114 controls in 2022). The two overlap significantly, which is why many companies pursue both rather than duplicating the work twice. See our full SOC 2 vs ISO 27001 comparison.
