What should organisations do when insurers ask for evidence of strong identity governance?

What insurers are really asking for when they request identity governance evidence

Underwriters are usually not looking for a raw export of every control event. They want a defensible view of how identities are governed, who can access what, how privilege is limited, and whether review and revocation actually happen in practice. Evidence should therefore be packaged as a control story, backed by a few concrete artefacts that show operating discipline rather than volume.

A useful package usually starts with the basics of IAM and IGA, because insurers want to see that identity lifecycle, entitlement management, and access governance are operating as a system rather than as isolated checks. NHI management can matter here too, since many environments now include service accounts, workload identities, and other machine-held access paths that IAM and IGA Basics and the NHI Lifecycle Management Guide both frame as governance and lifecycle problems, not just credential administration.

For insurers, the strongest signal is usually consistency. If authentication, access review, segregation of duties, and offboarding are all documented in one place, the underwriter can see that the organisation knows where privilege lives and how it is removed. That is also why many teams lean on Ultimate Guide to NHIs, Regulatory and Audit Perspectives when they need to explain control design in a way that maps to audit and renewal conversations.

Good evidence is usually selective. A short policy excerpt, a sample access review, a role or entitlement report, and proof of remediation are often more persuasive than a broad control catalogue. If the organisation can also show ownership of roles and a repeatable review process, the evidence becomes easier to assess and much harder to dismiss as paper compliance. That is the practical value of Access Reviews and Certification Guide and Role Mining and Role Design Guide as supporting references.

Insurers also care about whether governance reaches the identities that can do the most damage. A mature response distinguishes between ordinary user access, privileged access, and machine access, then shows that each is governed to an appropriate standard. A well-prepared evidence pack should make that distinction obvious rather than assuming the underwriter will infer it from generic policy language. Human vs Non-Human Identity is useful here because it reinforces why governance evidence must cover both people and systems.

Zero trust alignment helps when it is tied to observable controls, such as conditional access, least privilege, session oversight, and segmentation of critical systems. The key is to show that the organisation is not relying on trust in static network location or broad standing privilege. That is a stronger insurance narrative than saying “we follow zero trust principles” without proof.

Risk and Threat Considerations

Weak identity governance increases the likelihood that an insurer will assume hidden exposure exists, even if no incident has occurred. The main concern is not just control failure, but uncontrolled privilege accumulation, stale access, and weak offboarding, all of which can widen loss potential and make underwriting terms less favourable.

Failure mechanism: Missing or fragmented evidence often signals that access reviews are inconsistent, privileged accounts are not tightly monitored, or machine-held access is not included in the governance process. In practice, that creates a gap between written policy and actual access state, which is exactly where excessive exposure tends to accumulate.

Impact: The organisation can face tougher questions, slower renewals, exclusions, higher premiums, or demands for remediation before coverage is agreed. In more serious cases, weak governance evidence can also mask conditions that would make compromise easier to spread or harder to contain.

One point insurers often test indirectly is whether the organisation can detect and remove access fast enough after a role change, incident, or termination. If the answer depends on manual chase-up, the risk is not just administrative delay, it is lingering authority that can be abused before it is revoked.

Practitioner Guidance

What to prioritise: Build the evidence pack around the controls that most directly answer an underwriter’s loss question, not around the controls the security team finds easiest to export. The best artefacts usually show who has access, why they have it, how often it is reviewed, and what happens when access is no longer justified.

What to verify: Before sending anything, verify that the evidence covers current-state privilege, recent review activity, revocation workflow, and the systems that matter most to business continuity. If a report is stale, incomplete, or limited to one identity population, it will weaken the story rather than strengthen it.

Common mistake: Do not send raw logs or screenshots without interpretation. Insurers need a concise narrative that connects control design to operating practice, and they need enough structure to understand which controls are preventive, detective, and corrective.

Practitioner takeaway: Treat insurance evidence as a governance pack, not a compliance dump, and make sure it proves that access is actively managed across the full identity estate, including privileged and machine access.
