By NHI Mgmt Group Editorial TeamBased on Akeyless: “Akeyless vs. Keeper: Defining the Next Generation of Modern PAM” (November 30, 2025)

TL;DR: Akeyless argues that cloud-native PAM now needs ephemeral credentials, Zero Standing Privilege, and unified secrets handling because vault-centric designs still leave stored secrets and operational fragmentation in place. That architectural split matters because modern identity programmes must govern humans, workloads, and automation through the same access model, not separate legacy controls.


At a glance

What this is: This comparison frames dynamic PAM as a shift away from password-vault models toward ephemeral access, unified secrets handling, and tighter control over standing privilege across humans and machines.

Why it matters: It matters because IAM teams now have to design privileged access for cloud, DevOps, and machine identities without relying on session-only controls that leave underlying secrets and governance gaps intact.

Context

Privileged access management is no longer just about storing passwords and brokering sessions. In cloud-native environments, access needs to work across humans, workloads, automation pipelines, and machine identities that do not fit a vault-first operating model.

The article’s core governance question is whether PAM should keep managing access around stored credentials or move to ephemeral, on-demand issuance with Zero Standing Privilege. That distinction matters for identity programmes trying to reduce secret sprawl, simplify auditability, and support hybrid infrastructure without multiplying control planes.


Key questions

Q: Where does vault-based PAM fail in cloud-native environments?

A: Vault-based PAM fails when privileged access must scale across workloads, automation, and distributed cloud services that need credentials only for a task or session. The control still assumes there is a secret to store, rotate, and broker. In fast-moving environments, that assumption creates overhead and leaves the underlying standing-secret problem unresolved.

Q: Why do standing privileges create a higher access management risk?

A: Standing privileges increase risk because they remain available outside the task that justified them. That widens the window for misuse, makes review less meaningful, and increases the chance that access survives organisational change. The longer privilege persists, the more likely it is to outlive the decision that created it.

Q: What are the signs that a PAM programme is still secret-centric?

A: A PAM programme is still secret-centric when it depends on password rotation, session proxies, API keys, config files, or separate modules to approximate unified control. Another sign is that machine access still requires a stored credential somewhere in the workflow. Those patterns indicate the architecture has not moved to native identity issuance.

Q: How should teams decide between session controls and ephemeral credentials?

A: Use session controls when you need to reduce exposure around human access, but use ephemeral credentials when the workflow must remove persistent trust from the design entirely. Session controls still depend on an underlying secret model. Ephemeral credentials change the access model itself, which is why they fit automation and machine identity better.


Technical breakdown

Why vault-based PAM struggles with ephemeral infrastructure

Traditional PAM assumes privileged access can be mediated through stored credentials, password rotation, and session proxies. That model maps well to long-lived servers and human administrators, but it becomes awkward when workloads scale elastically, cloud services authenticate natively, and automation needs access without a durable secret to store. In this design, the secret remains the control point, so operational complexity grows as the environment becomes more dynamic. The article contrasts that with dynamic credential issuance, where access exists only for the session or task window and is revoked automatically after use.

Practical implication: treat stored secrets as a structural liability when access must be created and destroyed at machine speed.

Zero Standing Privilege changes the control point

Zero Standing Privilege means no persistent privileged credential is left in place waiting to be reused. Instead, access is issued on demand and expires after the task, which reduces the attack window and limits the value of stolen credentials. The important shift is not just shorter-lived accounts, but the removal of standing access as an operating assumption. For IAM and PAM teams, that changes how access is granted, monitored, and audited, because the governance control moves from stored secret management to issuance-time policy enforcement.

Practical implication: design privileged access around issuance-time controls, not post-issuance cleanup.

Machine identity native access vs secrets-for-secrets workflows

The article highlights a second architectural split: whether machines authenticate through native cloud and workload identity, or whether they depend on API keys, config files, and other standing secrets. Native identity approaches tie access to the platform’s own trust fabric, including cloud IAM roles, Kubernetes identities, mTLS, OIDC, and SPIFFE-style workload identity patterns. Secrets-for-secrets workflows preserve compatibility but leave residual credentials behind, which creates governance debt. For teams scaling DevOps and multi-cloud environments, the key question is whether the machine identity model removes the need for stored credentials or merely hides them in another layer.

Practical implication: map every machine access path to the identity primitive it actually uses, then eliminate residual standing secrets where possible.


Threat narrative

Attacker objective: The attacker seeks durable privileged access that can be reused across cloud, DevOps, or machine workflows without reauthentication.

  1. Entry begins when privileged access depends on stored secrets, API keys, or vault-backed credentials that can be reused outside the intended session window.
  2. Escalation occurs when those credentials persist long enough to support automation, cloud administration, or workload access across multiple systems.
  3. Impact follows when standing credentials and fragmented control planes expand the blast radius of compromise and make revocation slower than attacker use.

NHI Mgmt Group analysis

Vault-centric PAM creates governance debt the moment infrastructure becomes dynamic. A model built around stored credentials can still work for predictable human administration, but it becomes brittle when access is ephemeral, distributed, and automation-driven. The result is not just more tooling, but more places where policy, audit, and revocation have to be reconciled. Practitioners should treat vault dependency as a governance constraint, not just an architecture preference.

Zero Standing Privilege is now the more durable control objective for cloud-era privileged access. The critical issue is not whether passwords are rotated, but whether privileged access exists when it is not actively needed. That reframes PAM from secret retention to access issuance and revocation, which is a better fit for cloud-native operations and machine-heavy estates. The practical conclusion is that standing access should be the exception, not the operating baseline.

Ephemeral credential trust debt: every time a team keeps a temporary secret model tied to an underlying stored credential, it carries hidden governance debt. The access may look short-lived at the session layer, but the durable trust anchor still exists underneath. That is why session-only controls can reduce exposure without fully changing the identity model. Practitioners need to identify where temporary access still depends on persistent secret storage.

Machine identity has become a first-class PAM design issue, not a DevOps edge case. When workloads authenticate through cloud roles, service accounts, or workload identity frameworks, privileged access governance has to cover non-human actors directly. If those flows are layered on top of API keys or config files, the estate still contains standing secrets even if the interface looks modern. Teams should align PAM architecture to the actual identity primitive, not the deployment convenience.

The PAM market is splitting between vault modernization and identity-native access orchestration. That split matters because it changes what buyers should evaluate: session brokering alone no longer answers the governance problem when secrets, keys, and certificates are managed alongside workload identity. The field is moving toward consolidated control planes that can govern access, secrets, encryption, and lifecycle together. Practitioners should reassess whether their current PAM architecture can support that convergence.

What this signals

Ephemeral access is becoming the governance breakpoint. Once privileged workflows are expected to start and finish inside a short task window, access review alone is no longer enough because there may be no durable entitlement left to certify. That pushes programmes toward issuance-time policy, native workload identity, and faster revocation paths.

Standing-secret reduction is now a practical PAM objective, not a theoretical ideal. When a large share of identity-related breaches still involve privileged access paths, teams should focus on where secrets are stored, how they are inherited across automation, and which workflows can move to short-lived credentials without breaking operations.


For practitioners

  • Map every privileged access path to its identity primitive Inventory whether each pathway uses human login, service account, workload identity, API keys, or vault-issued credentials. Then separate paths that still depend on persistent secrets from those that can move to native identity or ephemeral issuance.
  • Eliminate standing credentials in high-frequency automation Target DevOps pipelines, cloud administration, and machine-to-machine access first, because these are the paths most likely to reuse secrets. Replace durable secrets with short-lived access where the workflow genuinely supports it.
  • Rework PAM policy around issuance time Set policy so privileged access is granted only when the task begins and is revoked automatically when the task ends. Audit for any process that still assumes a credential can wait to be reviewed later.
  • Consolidate secrets, keys, and certificate governance Use one governance model for secrets management, encryption keys, and certificate lifecycle controls so that audit, revocation, and ownership do not fragment across separate modules or teams.
  • Test whether session controls still leave residual trust Challenge every session-layer design with one question: does it still depend on a stored secret somewhere underneath? If the answer is yes, the control reduces exposure but does not remove the standing trust problem.

Key takeaways

  • Dynamic PAM changes the control problem from session brokering to access issuance, which matters most when humans, workloads, and automation share the same environment.
  • Stored secrets and vault fragmentation remain the weak point in cloud-native privileged access, especially where machine identities and automation scale faster than manual governance.
  • The strongest programme response is to remove standing privilege where possible and align PAM policy to native identity, short-lived credentials, and unified governance.

Key terms

  • Zero Standing Privilege: A control model in which an identity does not keep persistent access unless it is actively needed. For NHIs, this means credentials and permissions are issued for a narrow task and then removed. It reduces the time window and reuse value of stolen access.
  • Ephemeral Credentials: Ephemeral credentials are short-lived access artefacts issued for a limited task or session. They reduce the window for abuse, but they only improve security when paired with strong scope limits, telemetry, and automatic revocation at task completion.
  • Machine Identity: The digital identity of a machine, device, or workload, such as a server, container, or VM, used to authenticate it within a network. Sometimes used interchangeably with NHI, though NHI is the broader category.
  • Standing Secret: A standing secret is a long-lived credential that remains valid until it is manually replaced or revoked. In practice, it expands attack exposure because the secret can outlive the service change process, especially when ownership and usage tracking are incomplete.
