How should security teams decide between SOC 1 and SOC 2?

Why This Matters for Security Teams

SOC 1 and SOC 2 are often treated as reporting labels, but the distinction matters operationally when identity systems, service accounts, APIs, and automation can influence customer outcomes. SOC 1 is about controls relevant to financial reporting. SOC 2 is about trust services criteria, which usually maps more directly to security teams managing access, secrets, logging, and third-party integrations.

That difference becomes important in environments where non-human identities are embedded in release pipelines, payment flows, and data-sharing services. NHI Management Group research shows how quickly identity failures can turn into business exposure, including the Ultimate Guide to NHIs finding that 97% of NHIs carry excessive privileges, and the State of Non-Human Identity Security reporting that lack of credential rotation is cited by 45% of organisations as the top cause of NHI-related attacks.

Security teams should therefore ask not only what the assurance report says, but what kind of risk it is intended to evidence. A control set that satisfies a finance stakeholder may still leave gaps in API key governance, workload identity, or monitoring coverage. In practice, many security teams encounter SOC scope confusion only after a customer audit, procurement review, or incident has already exposed the mismatch.

How It Works in Practice

The practical decision starts with the service boundary. If the system or control environment can affect a customer’s financial statements, transaction integrity, or related reporting, SOC 1 is the relevant lens. If the concern is the security posture of the service itself, SOC 2 is usually the better fit. For most security teams, especially those operating identity-heavy platforms, SOC 2 maps more naturally to day-to-day control work.

That is because SOC 2 can capture the controls security teams actually operate: access restriction, secrets handling, logging, change management, vendor oversight, incident response, and data protection. For NHI-heavy environments, this often includes service account lifecycle controls, short-lived credentials, rotation discipline, and monitoring for over-privileged automation. The JetBrains GitHub plugin token exposure is a useful reminder that software supply chain trust can fail through a single exposed token, not just through human misuse.

In operational terms, teams should map control objectives to evidence:

• SOC 1: prove controls over financial processing, calculation logic, and reporting-impacting access.
• SOC 2: prove controls over security, availability, confidentiality, processing integrity, and privacy.
• For NHIs: show secret storage, rotation, least privilege, offboarding, and monitoring evidence.
• For third parties: show how OAuth apps, service integrations, and delegated access are approved and reviewed.

Current guidance suggests using NIST Cybersecurity Framework 2.0 as a control-mapping aid when translating technical evidence into assurance language. These controls tend to break down when teams assume a single attestation covers both financial reporting impact and broader security assurance, because the evidence model and audit objective are not the same.

Common Variations and Edge Cases

Tighter assurance scoping often increases audit effort, evidence collection overhead, and internal coordination, so organisations must balance reporting precision against operational cost. That tradeoff is especially visible when identity controls support both finance workflows and general production security.

Some services need both reports, but for different reasons. A payroll platform may need SOC 1 because access and calculations affect financial statements, while the same platform may also need SOC 2 because it processes sensitive employee data and depends on API keys, admin consoles, and vendor integrations. Likewise, a SaaS control plane may have no direct financial-reporting role yet still require a strong SOC 2 posture because compromised NHIs can create wide blast radius.

There is no universal standard for this yet, but best practice is evolving toward evidence that is specific to the risk being claimed. If the organisation is trying to reassure procurement teams, SOC 2 is usually the clearer artefact. If the organisation is trying to support a finance control narrative, SOC 1 is the stronger fit. When in doubt, scope by impact first, then by audience, and document where identity controls intersect with reporting or data protection obligations.

That approach is most likely to fail in highly integrated environments where a single service account can both change financial records and move sensitive data across systems, because the same control may need to satisfy two very different assurance narratives.
