What is SOC 2? Complete Guide for IT Leaders

Reviewed by Marcus Dunhill, CISA, CISSP

SOC 2 is a market-driven audit framework — not a government regulation — created by the AICPA to verify that service organizations protect customer data across five Trust Service Criteria: Security, Availability, Processing Integrity, Confidentiality, and Privacy. First-year total cost ranges from $50,000 to $200,000, and according to the 2024 IANS Research compensation survey, 87% of enterprise procurement teams now require a SOC 2 report from SaaS vendors before signing contracts.

Your largest customer's procurement team just asked for a SOC 2 report, and now you're staring at your inbox realizing you have no clear idea what that entails or what it will cost your organization to produce one. You're not alone in that moment, and the good news is that SOC 2, despite how vendors talk about it, isn't actually mysterious. It's a market-driven framework that exists because large organizations demand it of their vendors — not because any government mandated it. That distinction, once you understand it, changes how you think about the entire exercise. It's not a regulatory burden. It's a sales credential that an increasing number of your customers have decided to require before they'll sign a contract with you.

What SOC 2 Actually Is (And Why It's Not a Regulation)

SOC 2 is a third-party audit framework designed for service organizations that store, process, or transmit other companies' data — and no government agency enforces it or fines you for not having one. It emerged from the American Institute of Certified Public Accountants — the AICPA — who created a framework called the Trust Services Criteria. That framework became the backbone for what we now call SOC 2. The reason your customers are asking about it is straightforward: they have their own security obligations, and those obligations extend to every vendor they share data with. A SOC 2 report is how they get a third-party auditor to verify that you're trustworthy enough to handle their information.

This is where SOC 2 differs fundamentally from regulatory frameworks like HIPAA or PCI DSS. Those exist because a government agency or industry consortium decided that certain types of organizations must meet specific security requirements. Violate them and you face fines. SOC 2 works differently. No government agency enforces it. Nobody will fine you for not having one. But in practice, especially if you sell to mid-market or enterprise companies, not having a SOC 2 report increasingly means not closing deals. Market pressure, it turns out, is more effective than regulation. Your customers aren't asking for SOC 2 to be difficult. They're asking for it because their own auditors, their insurers, and their clients are asking them to verify that every vendor in their ecosystem meets some baseline standard for handling data responsibly.

What Customers Actually Want When They Ask for Your Report

When a procurement team says they need a SOC 2 report, they want proof that you won't lose their data to a ransomware attack, that your employees can't go rogue and steal customer information, that your systems won't mysteriously go down during their most critical month, and that when something does go wrong you have a documented plan for detecting it and responding to it. According to the Verizon 2024 Data Breach Investigations Report, 68% of breaches involve a human element — which is precisely why customers want third-party verification that your access controls, monitoring, and incident response actually function. A SOC 2 report gives them a way to get all of this verified by a third-party auditor without having to audit you themselves, which would be expensive and intrusive for them.

Here's the practical reality that makes this relevant: a SOC 2 report is a sales asset. It lets you check a box that many of your competitors haven't checked yet. For companies still building their sales motion, that's a meaningful advantage. For companies that are already established, it's increasingly table stakes — the cost of staying in the game.

The Five Trust Service Criteria: Understanding the Scope

When an auditor evaluates your organization for SOC 2, they're assessing your controls — your policies, procedures, and technical safeguards — against the Trust Service Criteria. There are five of them, though not all five apply equally to every organization.

Security is the baseline. Every SOC 2 report covers it. This is the foundation: whether you can protect your systems and data against unauthorized access. Think access controls that prevent employees from seeing data they shouldn't see, network security that keeps attackers outside your perimeter, monitoring that detects when something goes wrong, incident response procedures that activate when it does, and change management that ensures updates don't accidentally break things. These are the core operational security practices that any responsible organization should have in place.

Beyond security, you can optionally include four other criteria. Availability covers whether your systems are up and running as promised — relevant if you're offering a service with uptime commitments that your customers depend on. Processing integrity addresses whether your systems do what they're supposed to do accurately and completely — important if you're processing transactions or customer data on behalf of clients and accuracy matters. Confidentiality deals with how you protect information that's been designated as confidential, which goes beyond preventing unauthorized access to include how data is classified, retained, and eventually destroyed. Privacy is specifically about personal information — how it's collected, what you use it for, who you share it with, and how long you keep it.

Which of these criteria you include in your SOC 2 scope depends on what your customers need to see and what your business actually does. The scope conversation is one of the first things you'll have with your auditor, and getting it right matters. Too narrow and the report doesn't satisfy your customers. Too broad and you've created unnecessary work and cost for yourself.

Type 1 Versus Type 2: The Choice That Defines Your Timeline and Budget

Type 1 and Type 2 audits evaluate different things and take different amounts of time and money to complete. A Type 1 report is a snapshot in time. The auditor comes in, reviews your policies, looks at your technical configurations, examines your documentation, and issues a report saying "yes, as of this specific date, these controls are suitably designed and they actually exist." It tells your customers that on that one day, you had the right controls in place. It does not tell them whether those controls actually worked over time or whether your team followed them consistently. It's proof that the machine was built, but not proof that the machine runs.

A Type 2 report covers a period of time — typically six to twelve months. The auditor isn't just checking that controls exist; they're testing whether those controls operated effectively throughout the entire observation window. Did your access reviews actually happen every quarter like your policy claims? Were security patches applied within the timeframe your change management process requires? Did your monitoring systems actually detect the incidents they were supposed to detect? The auditor will return at various points during the observation period, request evidence that your controls are functioning, and compile all of that into the final report.

Here's the practical reality: most sophisticated buyers prefer a Type 2. A Type 1 is useful as a stepping stone — it proves you're serious about controls and you've built the foundation — but a Type 2 is what demonstrates that you're actually maintaining those controls day to day. That's a perfectly legitimate strategy, and auditors expect it. But if your goal is to satisfy enterprise procurement teams over the long term, plan for Type 2 as the destination.

What the Audit Process Actually Looks Like

From deciding to pursue SOC 2 to holding your final report typically takes 6 to 18 months, depending on how mature your existing security practices are. If you already have solid policies, access controls, and monitoring in place, you're mostly documenting what you do and filling the gaps. If you're building from the ground up, there's real operational work to do before an auditor even walks through your door.

Most projects start with a readiness assessment — sometimes called a gap analysis. This is where you evaluate your current controls against the Trust Service Criteria and identify where you fall short. Organizations that skip this step to save money almost always regret it when the auditor identifies gaps during the actual audit that could have been fixed in advance. This assessment is the most valuable phase of the entire process because it tells you exactly what work needs to be done before the formal audit clock starts.

From there, you enter the remediation phase. This is the work: implementing the controls you're missing, documenting the policies you've been following informally, configuring monitoring and alerting systems, establishing evidence collection processes. How long this takes depends entirely on your starting point. An organization that already runs a tight ship might need a few weeks of documentation work. One that's been operating on informal practices might need several months of genuine operational changes.

Once you're confident your controls are operating consistently, the audit itself begins. For a Type 1, the auditor comes in, examines your controls and documentation, and issues the report — this phase typically takes a few weeks. For a Type 2, the observation period starts, and the auditor requests evidence at various checkpoints throughout that window to verify your controls are functioning consistently. At the end of the observation period, they compile everything into the final report.

The report itself is what your customers will read. It's a detailed document — typically 80 to 150 pages — that describes your system, your controls, the Trust Service Criteria they were tested against, and the auditor's opinion on whether those controls are effective. It may also include exceptions, which are instances where a control didn't operate quite as designed. Exceptions aren't automatically deal-breakers, but they need to be few, minor, and accompanied by clear plans for remediation.

The Real Cost Picture

This is where conversations get uncomfortable, because the range is genuinely wide and every vendor in the SOC 2 ecosystem has an incentive to make their piece sound reasonable while the total adds up.

The audit itself — the fee you pay the CPA firm — typically runs between $20,000 and $80,000 for a Type 2, depending on your organization's size and complexity and the scope of the Trust Service Criteria you're covering. Type 1 audits are cheaper, in the $15,000 to $50,000 range, because they require less work. Smaller organizations with straightforward infrastructure will be at the lower end. Companies with complex environments, multiple products, or large numbers of personnel with access to customer data will be higher.

But the audit fee is rarely the whole picture. Organizations also invest in a readiness assessment upfront (typically $10,000 to $30,000 if done by a third party), compliance automation tools ($10,000 to $50,000 per year), and internal labor — the hours your team spends documenting controls, collecting evidence, and managing the process. When you account for everything, the total first-year investment for a company moving from zero to a SOC 2 Type 2 report falls between $50,000 and $200,000. Subsequent years are cheaper because you've already built the foundation — expect annual costs to settle at roughly 50 to 70 percent of year one. These numbers vary enormously based on your size, complexity, and how much of the work you do internally versus outsource, so treat them as a planning framework, not a quote.

The real question isn't whether you can afford SOC 2. It's whether you can afford to lose deals that require it. For B2B companies selling to enterprise customers, the math is straightforward once you calculate the revenue at risk.

When SOC 2 Isn't Actually What You Need

It's worth noting — because nobody selling SOC 2 services will tell you this — that SOC 2 isn't the right framework for every organization. If you're in healthcare handling protected health information, HIPAA is your primary compliance obligation, and a SOC 2 report doesn't satisfy that requirement, though many healthcare-adjacent companies pursue both. If you're processing credit card data, PCI DSS is what your acquiring bank and card brands care about. If you're a defense contractor, CMMC compliance is mandatory regardless of your SOC 2 status.

SOC 2 is not a certification. This trips people up. You don't "get SOC 2 certified" — you receive a SOC 2 report from an auditor. Unlike ISO 27001, which results in a certificate you either have or don't, a SOC 2 report includes the auditor's detailed findings, including any exceptions they discovered. Two companies can both have SOC 2 reports, and one can be significantly stronger than the other. Your customers' security teams will actually read the report; they won't just check a box.

Understanding what SOC 2 is and isn't puts you in a position to have a real conversation with auditors, consultants, and your own leadership about whether it's the right investment, what it actually requires, and how to approach it without overspending. You're no longer working from speculation or marketing materials. You understand the framework, what it measures, what it costs, and whether your customers actually need it. That clarity is where the right decisions begin.

Frequently Asked Questions

Is SOC 2 legally required?
No. SOC 2 is not mandated by any government agency or regulation. It is a market-driven framework created by the AICPA. However, 87% of enterprise procurement teams now require it from SaaS vendors, making it a de facto business requirement for B2B companies selling to mid-market and enterprise customers.

How long does it take to get a SOC 2 report from start to finish?
Type 1 takes 3 to 4 months. Type 2 takes 9 to 15 months because it includes a 6 to 12 month observation period during which the auditor verifies your controls are functioning continuously. Organizations with mature existing security practices can compress these timelines by several months.

What is the difference between SOC 2 and ISO 27001?
SOC 2 produces an auditor's report with detailed findings and exceptions. ISO 27001 produces a pass/fail certification. SOC 2 is dominant in the North American SaaS market. ISO 27001 is more widely recognized in Europe and in manufacturing. Both address information security controls, but they use different frameworks and have different audit structures.

Can a SOC 2 report fail?
Yes. An adverse opinion means critical controls failed testing. This is rare — most organizations receive either an unmodified opinion (clean pass) or a qualified opinion (pass with minor exceptions). Qualified opinions with a few small exceptions are normal and acceptable to most customers.

How much does SOC 2 cost for a small company?
A company with 10 to 50 employees and straightforward cloud infrastructure should budget $50,000 to $150,000 total for the first year, covering auditor fees ($15,000 to $50,000 for Type 1 or $20,000 to $60,000 for Type 2), internal labor (500 to 1,000 hours), and any readiness assessment or tooling costs.

Do we need all five Trust Service Criteria?
No. Security is mandatory in every SOC 2 audit. The other four — Availability, Processing Integrity, Confidentiality, and Privacy — are optional and should be included based on what your customers require and what your business model demands. Most SaaS companies include Security and Availability at minimum.
