How do organisations know whether a new IAM platform is actually reducing risk?

Why This Matters for Security Teams

A new IAM platform is only risk-reducing if it changes the security outcomes that matter: fewer standing privileges, fewer brittle exceptions, and more consistent enforcement across systems that used to be governed by spreadsheets and local workarounds. For non-human identities, that means the platform must improve how secrets, workload identities, and access policies are issued and audited, not just make the admin console easier to use. Guidance in the NIST Cybersecurity Framework 2.0 and NHIMG research on the Top 10 NHI Issues both point to the same operational test: can the organisation prove access is tighter, more consistent, and easier to revoke?

This is where many rollouts get misread. A platform can reduce manual effort while leaving long-lived secrets, weak role design, and inconsistent policy enforcement untouched. In that case, the risk profile has not improved, it has only become more polished. NHIMG’s 2024 Non-Human Identity Security Report found that 88.5% of organisations say their non-human IAM practices lag behind or merely match human IAM, which is a reminder that tooling alone rarely closes the governance gap. In practice, many security teams discover this only after audit findings, privilege creep, or a secret leak has already exposed the weakness.

How It Works in Practice

The practical way to judge a new IAM platform is to compare pre- and post-change control evidence, not product claims. Security teams should look for measurable reductions in custom access exceptions, faster revocation, better certificate hygiene, and more uniform policy decisions across SAP and non-SAP systems. That evidence should include entitlement scope, secret lifetime, approval path, and whether access was granted by rule, by role, or by runtime policy.

For non-human identities, the strongest signal is whether the platform moves access from static assignment toward short-lived, context-aware enforcement. That often means replacing shared credentials with workload identity, issuing JIT credentials for specific tasks, and using policy-as-code so access can be evaluated at request time. Standards such as NIST Cybersecurity Framework 2.0 help teams structure the control objectives, while NHIMG’s Ultimate Guide to NHIs highlights the recurring failure mode: access looks governed, but secrets and privileges remain durable behind the scenes.

• Compare standing privileges before and after migration.
• Count manual exceptions that still require human intervention.
• Review whether credentials expire automatically or are rotated on schedule.
• Check whether the same policy is enforced consistently across platforms and clouds.
• Validate that audit evidence is generated automatically, not reconstructed later.

When those controls work, the platform should reduce the effort needed to grant, review, and revoke access while also lowering the number of identities that can be abused at rest. The 2024 report notes that only 19.6% of security professionals are strongly confident in their organisation’s ability to securely manage non-human workload identities, which makes confidence a weak metric on its own. These controls tend to break down in hybrid estates with embedded legacy jobs and SAP integrations because entitlement inheritance, custom connectors, and shared service accounts are difficult to standardise.

Common Variations and Edge Cases

Tighter governance often increases migration effort and operational friction, so organisations have to balance cleaner control models against business continuity and release velocity. That tradeoff matters most when legacy applications cannot support modern token flows or when third-party tools insist on persistent service accounts.

Best practice is evolving, but current guidance suggests that exceptions should be the thing that shrinks fastest after rollout. If exception volume stays flat, the platform may simply be recreating the old access model in a new wrapper. This is especially common in SAP-heavy environments, where local role design, transport dependencies, and approval routing can hide the real access path unless evidence is normalized across systems. The 2024 ESG Report: Managing Non-Human Identities shows how widespread NHI compromise already is, which reinforces why governance must be verifiable rather than assumed.

The clearest edge case is a platform that centralises identity administration but does not reduce credential lifetime, secret sprawl, or overbroad entitlements. That outcome may improve visibility, but it does not necessarily reduce risk. Organisations should treat that as a monitoring gain, not a security win, until the access model itself becomes simpler to operate and easier to audit.
