How should organisations reduce access risk when privileged accounts are still managed with manual recertification processes?

Organisations should replace manual privilege recertifications with consistent, policy-based reviews that are tied to ownership, business need, and expiry. Manual processes are slow, easy to miss, and often leave access active after it is no longer justified. A stronger approach combines least privilege, regular attestation, and revocation workflows so privileged access is always current and defensible.

Why This Matters for Security Teams

Manual recertification looks controlled on paper, but for privileged access it often turns into a periodic checkbox exercise that lags behind real business need. When reviewers are working from stale spreadsheets, unclear ownership, or vague role labels, excessive access stays active long after it should have been removed. That gap is especially dangerous for privileged accounts because one missed approval can preserve broad administrative reach across infrastructure, cloud, and production systems.

NHI Management Group has repeatedly shown that identity sprawl and weak lifecycle control are common failure points in modern enterprises, including the Ultimate Guide to NHIs and the Top 10 NHI Issues. The same pattern applies to privileged human access: if recertification is manual, ownership is ambiguous, and revocation is delayed, the process documents risk instead of reducing it. Current guidance from NIST Cybersecurity Framework 2.0 and OWASP Non-Human Identity Top 10 both reinforce the need for continuous governance, not occasional approval cycles.

In practice, many security teams discover privilege creep only after an audit finding, an access review exception, or an incident has already confirmed the gap.

How It Works in Practice

Reducing access risk starts by replacing ad hoc review packets with policy-based access governance that is tied to an owner, a business justification, and an expiry date. Reviews should not ask only, “Should this person still have access?” They should also ask, “What system, task, or ticket requires it, and when does that need end?” That shift makes revocation a normal outcome of the process instead of an exception. NIST SP 800-53 Rev 5 Security and Privacy Controls supports this direction through access enforcement, accountability, and review discipline.

For privileged access, the practical model is:

• Assign a named business owner and technical owner for each privileged account.
• Set explicit expiry or review cadence based on risk, not calendar convenience.
• Require evidence of ongoing need, such as a ticket, project, or operational role.
• Remove access automatically when the approver does not respond or the need is no longer valid.
• Track exceptions separately so recurring access does not become permanent by default.

The strongest programmes also reduce dependence on standing privilege by pairing recertification with NHI lifecycle management practices such as rotation, revocation, and offboarding. That matters because privileged accounts and service identities often overlap operationally, and the same weak control patterns appear in both. NHI Management Group research notes that 71% of NHIs are not rotated within recommended time frames, and only 20% have formal offboarding and revocation processes, which shows how easily access persists when lifecycle ownership is unclear.

These controls tend to break down in distributed environments with many application owners and no authoritative inventory, because reviewers cannot reliably tell what is still needed, what is duplicated, and what is already abandoned.

Common Variations and Edge Cases

Tighter recertification often increases operational overhead, so organisations must balance assurance against reviewer fatigue and service disruption. A monthly full review for every privileged account can create noise and encourage rubber-stamping, while a risk-based schedule with automated expiry can improve both speed and quality. Best practice is evolving, but current guidance suggests that high-risk administrative access should be reviewed more often than low-risk break-glass access, and that temporary elevation should be treated differently from persistent entitlements.

There are also edge cases where manual review is still unavoidable. Shared emergency accounts, legacy platforms without API support, and regulated environments with formal sign-off requirements may require human attestation. Even then, the review should be narrower: validate owner, usage, and expiry rather than re-approving broad standing access. For environments with secrets embedded in scripts or CI/CD systems, recertification alone is not enough. Access may be technically approved but operationally unsafe if the credential is copied, reused, or never rotated.

For a broader control perspective, the Regulatory and Audit Perspectives section of the Ultimate Guide to NHIs is useful because it links lifecycle discipline to evidence and accountability. Organisations should treat recertification as one control in a larger privilege-minimisation programme, not as proof that access is genuinely under control.

Manual recertification is least effective where privilege changes quickly, where ownership is shared across teams, and where revocation is not automated at the end of the review cycle.
