Start with the credentials that can cause the most damage if exposed, usually administrator, service and vendor access accounts. Then extend the same lifecycle model to broader shared credentials so the organisation does not fix only the top of the risk stack while leaving other high-value secrets unmanaged.
How teams should sequence PAM and EPM
Use the access path that creates the largest blast radius first, then push the same control model outward. In practice, that usually means securing administrator, service, vendor and other high-impact credentials before expanding to endpoint privilege workflows, because the fastest way to reduce damage is to remove durable, high-value standing access.
That sequencing avoids a common mistake: treating endpoint elevation as a separate queue when the organisation already has exposed shared credentials, overprivileged admin accounts or remote support paths that can be used to reach the same systems.
Why the order should follow blast radius, not product category
PAM and EPM solve overlapping but not identical problems. PAM is usually the better first move when the main issue is standing privileged access, vaulting, session control, break-glass handling, vendor access or shared administrative credentials. EPM becomes the natural next step when the question shifts to local admin rights, endpoint task elevation, software installation privileges and reducing day-to-day friction without leaving users permanently elevated.
The right order is therefore driven by risk concentration. If one credential can open servers, cloud consoles, remote admin tools or critical business platforms, that credential belongs ahead of broader endpoint privilege work. If endpoint admin rights are the main exposure, EPM can lead, but it should still be tied to lifecycle control so the organisation does not simply move from ad hoc elevation to ad hoc endpoint exceptions.
For teams comparing implementation paths, the most useful first filter is whether the control reduces access to a shared or reusable secret, or only reduces local privilege on a device. Shared secrets and remote admin paths usually deserve earlier attention because they are harder to detect when abused and often provide broader lateral movement potential than a single workstation privilege grant. A useful starting point is the Privileged Access Management Guide, which frames PAM as a lifecycle and session-control problem, not just a vault problem.
How to make the rollout practical without leaving gaps
Teams should map privileged access by account type, not by tool ownership. That means inventorying administrator, service, vendor, emergency and integration accounts first, then deciding which of those need vaulting, rotation, JIT elevation, session brokering or tighter review. EPM can then be layered onto endpoint admin rights, but it should inherit the same discipline around approval, expiry and auditability.
Where endpoint privilege and shared credentials overlap, sequence by the account that can reach the most systems. A vendor support account with broad remote access is usually a higher priority than a local admin right on one machine. A service account that authenticates to multiple production systems is usually a higher priority than a one-off endpoint elevation workflow. The organisation should extend the same lifecycle model across both so the control boundary does not stop at the first tool deployment.
That is why many teams pair PAM with service-account governance early. The Service Account Security Guide is useful here because it treats machine and shared access as an inventory, rotation and governance problem, while the Just-in-Time Access and Zero Standing Privilege Guide shows how to remove durable privilege rather than merely masking it.
What good looks like after the first phase
A sensible first phase produces fewer always-on privileged paths, shorter credential lifetimes and clearer ownership of every elevated account. Once that is in place, EPM should be used to eliminate routine local admin sprawl and replace it with controlled elevation for the cases that truly need it.
Teams should also validate that the rollout does not create a false sense of completion. If PAM covers only interactive administrators while service accounts, break-glass accounts and vendor access remain unmanaged, the risk reduction is partial. If EPM covers endpoints but privileged sessions and shared credentials still exist elsewhere, the organisation has modernised the surface but not the exposure. The practical benchmark is whether the highest-risk access paths have moved from permanent, reusable and broadly reachable to time-bound, monitored and explicitly owned. The Privileged Session Management Guide is a strong companion for the monitoring and brokering side of that benchmark.
Risk and Threat Considerations
The main sequencing risk is assuming PAM and EPM are interchangeable. They are not. If teams start with the wrong layer, they can leave the most dangerous credentials untouched while spending months reducing low-value local privilege. That creates a gap where attackers still have a reusable path into core systems even though the endpoint experience looks improved.
Failure mechanism: Standing admin, service or vendor credentials remain valid while endpoint elevation is being redesigned, so a compromise can still lead to broad access, lateral movement or destructive action through the untouched path.
Impact: The organisation reduces inconvenience before it reduces blast radius, which can leave the most damaging access paths available during the rollout and delay meaningful risk reduction.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 addresses the attack surface, NIST SP 800-53 Rev 5 sets the technical controls, and ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 — Improper Offboarding | Sequencing privileged access depends on lifecycle control for shared admin, vendor and service credentials. |
| NHI-05 — Overprivileged NHI | The question is about prioritising the highest-impact privileged credentials before lower-risk endpoint rights. | |
| NHI-07 — Long-Lived Secrets | PAM-first sequencing often targets durable privileged credentials before local elevation patterns. | |
| Recommendation — Inventory privileged accounts first and remove stale access paths before broadening endpoint elevation controls. Reduce excessive privilege on high-value credentials before expanding control to endpoint admin workflows. Shorten secret lifetime for the most powerful accounts before widening privilege-management coverage. | ||
| NIST SP 800-53 Rev 5 | IA-5 — Authenticator Management | The decision centers on managing privileged credentials, rotation and lifecycle before broader endpoint elevation. |
| AC-6 — Least Privilege | PAM and EPM both implement least privilege, and sequencing should target the largest excess privilege first. | |
| IA-2 — Identification and Authentication (Organizational Users) | Administrator access is explicitly part of the rollout order, so authenticating privileged users is material. | |
| Recommendation — Apply IA-5 to rotate and govern the most powerful credentials first. Use AC-6 to reduce the highest-risk standing access before expanding privilege controls. Strengthen privileged user authentication before extending elevation workflows to more users. | ||
| ISO/IEC 27001:2022 | A.5.15 — Access control | The topic is fundamentally about deciding which privileged access paths to control first. |
| Recommendation — Prioritise access controls around the credentials and roles with the largest blast radius. | ||
Practitioner Guidance
What to prioritise: Start with the credential class that can touch the most critical systems, then move to endpoint admin rights only after those high-impact paths are inventoried and owned. If a single account can affect multiple production systems, it belongs ahead of local workstation elevation.
What to verify: Confirm that the first phase covers service, vendor, emergency and shared admin access, not just interactive user privilege. The control is incomplete if it only changes the endpoint while leaving reusable secrets and remote support access outside the same lifecycle.
Practitioner takeaway: Choose PAM or EPM first by blast radius, not by technology preference, because the fastest risk reduction comes from controlling the access path that can do the most damage if compromised.
