When does PAM create more risk than it reduces?

Why This Matters for Security Teams

PAM is meant to reduce exposure by narrowing who can reach privileged systems, but it can become a risk amplifier when the operating model is too brittle for day-to-day use. If administrators bypass the platform, keep break-glass paths open, or rely on manual approval chains, the organisation ends up with fragmented privilege control rather than true reduction. That is especially dangerous in environments where service accounts, automation, and APIs already outnumber human administrators.

NHIMG’s Ultimate Guide to NHIs notes that 97% of NHIs carry excessive privileges, which is exactly the kind of condition PAM is supposed to correct. But control design only works if it is consistently adopted across interactive admins, machine identities, and emergency workflows. The NIST Cybersecurity Framework 2.0 also makes clear that governance has to be repeatable, measurable, and embedded in operations, not dependent on heroic manual enforcement. In practice, many security teams encounter PAM failure only after exception sprawl has already created unmonitored privileged paths.

How It Works in Practice

PAM reduces risk when it enforces least privilege, time-bounded elevation, session recording, and credential checkout in a way that users can actually follow. It increases risk when it introduces friction so high that teams create alternate admin accounts, share credentials informally, or leave long-lived access in place to keep systems running. The core question is not whether PAM exists, but whether it is the primary path for privilege or merely a control layer people work around.

For human operators, strong PAM typically includes just-in-time elevation, approval workflows for sensitive tasks, and automatic revocation after use. For non-human identities, the design is different: access should be driven by workload identity, task context, and short-lived secrets rather than standing privilege. That is why NHIMG’s Top 10 NHI Issues consistently places excess privilege and weak rotation among the highest-risk patterns. Where possible, organisations should pair PAM with vaulting, rotation, and policy-based session controls so that privileged actions are provable, time-limited, and attributable.

• Use PAM for privileged humans, but do not force machine automation through the same manual approval path.
• Issue short-lived credentials per task instead of keeping standing admin rights open.
• Record and review privileged sessions, especially where production access can alter data or secrets.
• Measure exception volume, because recurring overrides usually signal that the control design is misaligned with operations.

These controls tend to break down in CI/CD-heavy environments and 24/7 production operations because urgent changes push teams toward shared break-glass access and unreconciled exceptions.

Common Variations and Edge Cases

Tighter PAM often increases operational overhead, requiring organisations to balance stronger privilege controls against uptime, release speed, and support responsiveness. That tradeoff is real, and there is no universal standard for this yet, especially in hybrid estates where legacy systems cannot easily support modern vaulting or time-bound elevation.

One common edge case is emergency access. Break-glass accounts are sometimes necessary, but they should be rare, heavily monitored, and rotated immediately after use. Another is third-party administration, where contractors or vendors need bounded access to production systems. If PAM policies are too rigid, those users will seek unsanctioned access paths. If they are too loose, the organisation effectively normalises standing privilege.

Current guidance suggests that the safest PAM programs treat exceptions as design defects, not operational conveniences. That means reviewing where people bypass the platform, where admins keep local root access, and where service accounts still rely on static credentials. For broader NHI governance, the problem often becomes visible first in credential sprawl and failed offboarding, not in the PAM console itself. NHIMG’s Ultimate Guide to NHIs — Why NHI Security Matters Now shows why the attack surface keeps expanding when privileged access is not continuously governed.
