SOC 1 vs SOC 2

If you're a Compliance Officer or CISO you've encountered the acronyms SOC 1 and SOC 2 and maybe felt that familiar twinge of confusion about which one your organisation actually needs. You're not alone. These reports share similar names, are both issued by certified public accountants, and often come up in the same procurement conversations. Yet they serve very different purposes, target different audiences, and evaluate entirely different sets of controls.

Let's explain the core differences, then dive into what a SOC 2 Type 2 report actually contains, because that's usually what SaaS and tech companies are asked to produce when customers want assurance that their data is safe.

The Core Difference

SOC 1 reports focus on controls relevant to financial reporting. They're designed for service organisations whose systems affect their clients' financial statements (payroll processors, billing platforms, or benefits administration providers). The audience for a SOC 1 report is typically the client's auditor or controller, who needs to assess whether your controls could introduce material misstatements into their financial records.

SOC 2, by contrast, evaluates operational risk management and data protection. It's built on the AICPA's Trust Services Criteria and assesses how well you protect customer data against security, availability, processing integrity, confidentiality, and privacy risks. SOC 2 is the report of choice for SaaS companies, cloud service providers, data centres, and any business that stores or processes sensitive customer information. Your audience here is not auditors but  prospective customers, security teams, and procurement officers who want proof that you handle their data responsibly.

Both SOC 1 and SOC 2 come in Type 1 and Type 2 variants. Type 1 reports assess whether your controls are designed appropriately at a specific point in time. Type 2 reports go further: they test whether those controls operated effectively over a period—typically six to twelve months.

For most SaaS and tech teams, SOC 2 Type 2 is the gold standard. It demonstrates not just that you have the right policies on paper, but that you've been consistently applying them, monitoring them, and remediating issues over time.

A SOC 2 Type 2 report is a comprehensive document that tells the story of your organisation's control environment over a defined period. Here's what it includes:

1. Independent auditor's opinion

This is the auditor's formal attestation. It states whether, in their professional opinion, your system description is fairly presented, your controls are suitably designed, and they operated effectively throughout the observation period. An unqualified ("clean") opinion is what you're aiming for.

2. Management's assertion

Your executive team (typically the CEO or CTO) provides a written statement affirming that the system description is accurate, that controls were in place, and that they operated as designed during the audit period.

3. System description

This narrative describes your services, infrastructure, software, people, procedures, and data flows. It explains what you do, how you do it, and the boundaries of the audit scope (e.g., which products, data centres, or third-party services are included).

4. Trust Services Criteria and Control Objectives

The report maps your controls to the AICPA's Trust Services Criteria:

• Security (mandatory): Protects against unauthorised access—logical and physical.
• Availability (optional): Ensures systems are operational and usable as agreed.
• Processing Integrity (optional): Confirms system processing is complete, valid, accurate, timely, and authorised.
• Confidentiality (optional): Protects information designated as confidential.
• Privacy (optional): Addresses the collection, use, retention, disclosure, and disposal of personal information.

Who needs a SOC 2 report typically determines which criteria to include. Most SaaS organisations pursue Security as a minimum, often adding Availability and Confidentiality based on customer requirements.

5. Tests of controls and results

This is the heart of the Type 2 report. For each control, the auditor describes the tests performed, the sample size, the period covered, and the results. You'll see entries like:

• "We inspected 25 access review logs over the 12-month period and confirmed that quarterly access reviews were performed and documented."
• "We examined firewall change logs and verified that all changes were approved in the ticketing system."

If any controls failed or exceptions were noted, they're documented here along with management's remediation plan.

6. Complementary User Entity Controls (CUECs)

These are controls that you expect your customers to implement. For example, if you provide an application, you might note that customers must enforce strong password policies on their end. CUECs clarify the shared responsibility model.

7. Other information (optional)

Some reports include management responses to exceptions, additional context, or appendices detailing sub-service organisations (third-party vendors) and how their controls were assessed.

A Type 1 report can serve as a milestone or proof-of-concept, but it's increasingly insufficient for enterprise buyers. Type 2 provides the evidence that controls aren't just theoretical but they've been tested in the real world, over time, under normal operating conditions. It's the difference between saying "we have a process" and proving "we follow the process consistently."

Practical Next Steps

If you're preparing for your first SOC 2 Type 2 audit, start with a readiness assessment. Identify control gaps, gather evidence systematically, and choose an observation period that balances speed with credibility.

Understanding the distinction between SOC 1 and SOC 2, and knowing exactly what a Type 2 report delivers, puts you in a much stronger position to navigate compliance requirements, answer customer questions with confidence, and turn assurance into a competitive advantage.
