Start by separating authentication needs from governance needs. If SSO, MFA, or federation still work, keep the IdP and add a governance layer that automates joiner mover leaver workflows, access certifications, and segregation of duties. This avoids a disruptive platform swap when the real problem is lifecycle control, not login. Use the evaluation to confirm audit evidence, revocation speed, and directory coverage.
Why This Matters for Security Teams
The evaluation mistake is assuming a sign-in problem when the real exposure sits in governance. If authentication still works, replacing an IdP can create migration risk without fixing the control gap that auditors, incident responders, and platform owners actually care about: who can get access, for how long, and whether it is removed fast enough when roles change. NHI Management Group’s Ultimate Guide to NHIs notes that only 20% of organisations have formal processes for offboarding and revoking API keys, which is a governance failure, not a login failure.
That distinction matters because identity governance controls joiner mover leaver workflows, access reviews, segregation of duties, and evidence collection across directories and applications. In contrast, an IdP primarily handles authentication, federation, and session control. Security teams that conflate the two often overbuy an SSO replacement while leaving excessive privileges, delayed revocation, and weak audit trails untouched. The NIST Cybersecurity Framework 2.0 treats identity and access management as an ongoing governance function, not just a sign-in service. In practice, many security teams discover the gap only after a failed access review or a slow offboarding event has already exposed the weakness.
How It Works in Practice
A practical evaluation starts by separating control planes. First, confirm whether the current IdP still satisfies authentication, federation, and conditional access requirements. If it does, keep it in place and assess a governance layer that can orchestrate entitlements across SaaS, cloud, directories, and privileged systems. NHI Management Group’s Lifecycle Processes for Managing NHIs emphasizes that lifecycle coverage is central when identities outnumber human users and change faster than manual reviews can keep up.
The shortlist should be judged on operational outcomes, not branding. Look for:
- Joiner mover leaver automation that updates entitlements from HR, ITSM, or directory events.
- Access certification campaigns that produce review evidence, approver history, and exception tracking.
- Segregation of duties checks that detect conflicting entitlements before they reach production.
- Revocation workflows that can remove access across primary directories, downstream apps, and privileged platforms.
- Directory and connector coverage broad enough to reflect how the enterprise actually stores identity data.
For control language, anchor the evaluation in NIST SP 800-53 Rev 5 Security and Privacy Controls, especially access enforcement, account management, and audit evidence. Security teams should also validate whether the tool can prove revocation speed with logs rather than promises, because auditors will ask for timestamps, not intent. In practice, the best alternative is often a governance layer that integrates with the existing IdP instead of replacing it, because the hard part is policy execution across many systems, not the login screen. These controls tend to break down when access is created outside the main directory, such as in local admin accounts, legacy apps, or CI/CD service connections, because the governance tool cannot see what the enterprise does not connect.
Common Variations and Edge Cases
Tighter governance often increases administrative overhead, so organisations have to balance review depth against business speed. That tradeoff becomes sharper in hybrid environments, where cloud apps, on-prem directories, and privileged access workflows do not share a clean identity model. Current guidance suggests that the most effective programs do not force every entitlement into one product category; instead, they define which controls belong to the IdP, which belong to governance, and which require PAM or workflow automation.
There is no universal standard for this yet, but best practice is evolving toward measurable outcomes: time to revoke, percentage of applications covered, quality of certification evidence, and completeness of directory coverage. The Top 10 NHI Issues highlights why this matters when access sprawl extends beyond human users, because entitlement drift and stale access usually originate in the same weak lifecycle processes. Teams should be cautious about any platform that claims to solve sign-in and governance equally well without showing how it handles access reviews, deprovisioning, and exceptions across multiple systems. In highly regulated estates, the practical answer is often a layered model: keep the IdP, add governance, and use dedicated privileged controls where the risk justifies it.
