Why do SaaS companies pursue SOC 2 even though it is not a legal requirement?

Why This Matters for Security Teams

SOC 2 is not a law, but for SaaS vendors it often functions like a market-access control. Buyers use it to compare providers, legal teams use it to reduce contract risk, and security teams use it to demonstrate that controls are not just aspirational. That matters because the real hurdle is rarely whether a company can pass an audit once; it is whether it can sustain control operation across engineering, support, cloud, and vendor workflows.

Current guidance suggests that SOC 2 becomes most valuable when an organisation must show repeatable control design and evidence, not just a policy set. The framework maps naturally to common expectations around access control, change management, incident handling, and monitoring, which is why it keeps appearing in procurement conversations even without being legally mandated. The ENISA Threat Landscape reinforces why buyers care about demonstrable control maturity: supply chain exposure, credential abuse, and operational failures continue to drive real business risk.

In practice, many security teams encounter SOC 2 only after a large customer asks for it during procurement, rather than through intentional control maturity planning.

How It Works in Practice

SOC 2 is built around the Trust Services Criteria, so SaaS companies pursue it to show that controls over security, availability, confidentiality, processing integrity, and privacy are operating in a consistent way. The audit itself does not certify that a company is breach-proof. It verifies that the company has defined controls, collected evidence, and operated them over a period of time.

For cloud-first SaaS firms, that usually means evidence from IAM, logging, change management, endpoint protection, backup processes, vendor oversight, and incident response. A strong program starts before the audit by closing obvious gaps such as shared admin accounts, undocumented production access, weak joiner-mover-leaver workflows, and missing review evidence. The control set often overlaps with security baselines already described by NIST Cybersecurity Framework, which is one reason SOC 2 can be operationally useful even when customers never ask for the report directly.

In practice, the process usually involves:

• Defining the scope of systems and services covered by the audit
• Assigning owners for each control so evidence is repeatable, not ad hoc
• Collecting logs, tickets, approvals, and review records across the audit period
• Testing whether access approvals, monitoring, and response actions actually happened
• Documenting exceptions and remediation so buyers can assess risk honestly

Many SaaS companies also use SOC 2 to reduce repeated questionnaires by pointing to one auditable control narrative instead of rebuilding the same answer for every prospect. Where identity is involved, the practical emphasis is on privileged access, authentication, and review of non-human credentials such as service accounts and API keys, because those controls often drive audit findings and customer concern. These controls tend to break down in fast-growing SaaS environments where engineering teams ship changes continuously but evidence collection is still manual and fragmented across multiple systems.

Common Variations and Edge Cases

Tighter audit readiness often increases operational overhead, requiring organisations to balance sales enablement against the cost of evidence collection and control maintenance. That tradeoff becomes sharper for startups, multi-product platforms, and companies using outsourced development or distributed cloud environments.

Best practice is evolving around how far SOC 2 should extend into software supply chain controls, AI-enabled features, and non-human identity governance. There is no universal standard for this yet, but buyers increasingly expect more than basic policy statements. For example, a SaaS company with agentic workflows or AI-assisted automation may need to show how tool access, secret handling, and human approval boundaries are governed, even if those details sit outside the narrowest reading of traditional audit scope. Where those systems affect customer data or service availability, the controls also intersect with broader resilience expectations reflected in ENISA Threat Landscape analysis and modern supply chain risk thinking.

SOC 2 is also not equally valuable in every market. Some buyers care more about ISO alignment, sector-specific regulations, or deeper technical due diligence, while some smaller customers only want a simple assurance story. The practical decision is less about chasing a badge and more about whether the report helps the company win trust, shorten procurement, and prove that its controls can survive scrutiny when scale, regulation, or incident response pressure increases.
