Who should own the decision when both PAM and IGA are needed?

Why This Matters for Security Teams

When PAM and IGA both touch the same privileged account, the failure mode is rarely technical first. It is governance ambiguity: one team thinks the other owns approval, review, rotation, or removal. That is exactly how over-entitled service accounts, orphaned credentials, and stale access paths persist long after a business change.

This matters because PAM is usually optimized for privilege enforcement at the point of use, while IGA is optimized for joiner-mover-leaver lifecycle control, certification, and evidence. If ownership is unclear, the controls can exist in parallel but fail in combination. NHI Mgmt Group’s research shows that 97% of NHIs carry excessive privileges, and 71% are not rotated within recommended time frames in the Ultimate Guide to NHIs. That is not a tooling problem alone; it is a decision-rights problem.

Security teams often discover the gap only after a breach review or audit exception, rather than through intentional control design. In practice, many security teams encounter duplicated control ownership only after a privileged account has already outlived the system it was meant to protect.

How It Works in Practice

The cleanest operating model is to make the identity programme accountable for the end-to-end decision, then split execution responsibilities. PAM should own the controls that restrict and broker privileged use, while IGA should own lifecycle governance, access certification, and evidence that access remains justified. That division keeps the control plane coherent without forcing one team to manage every task.

In practice, the identity programme should define the policy and escalation path for any account that is both privileged and governed. Security can own the privileged access standard, including session controls, checkout rules, break-glass handling, and vault requirements. Governance can own entitlement approval, periodic recertification, and removal workflows. The decision should be visible in a RACI or control matrix so no one assumes the other team has handled revocation, rotation, or review.

Current guidance from NIST Cybersecurity Framework 2.0 supports this split by emphasizing governance, access control, and continuous oversight rather than tool-specific ownership. For NHI-heavy environments, that model should extend to service accounts, API keys, and automation identities, not just human users. Where possible, tie privileged account ownership to a named business service or application owner, then require both PAM and IGA controls to reference the same authoritative record.

This approach is reinforced by real incidents such as the BeyondTrust API key breach, where access control and operational handling of secrets became inseparable from governance, and the Schneider Electric credentials breach, which highlights how credential exposure quickly becomes an identity and privilege problem. These controls tend to break down when privileged access is embedded in DevOps pipelines and no single team owns the approval, rotation, and retirement path end to end.

Common Variations and Edge Cases

Tighter segregation of duties often increases coordination overhead, requiring organisations to balance speed against control clarity. That tradeoff becomes sharper when PAM and IGA are both managing the same non-human identity, because service uptime, release velocity, and auditability all compete for the same workflow.

There is no universal standard for this yet, but current practice suggests a few useful patterns. For shared admin accounts, PAM may own day-to-day checkout controls while IGA owns who may be assigned that entitlement and how often it must be recertified. For service accounts, the application owner often becomes the business approver, with the identity programme enforcing the policy and preserving evidence. For emergency access, PAM usually handles the break-glass process, while IGA documents the exception, duration, and post-event review.

The main edge case is when organisations treat PAM as “operational security” and IGA as “compliance only.” That split leaves a gap in revocation and entitlement drift. The better model is one policy owner, two control executors, and one shared source of truth for the identity record. If that source of truth does not exist, ownership disputes will keep reappearing every time a privileged account must be rotated, certified, or retired.
