JIT-Native vs. PAM-with-JIT

Before you evaluate vendors, you need to answer the architecture question. JIT-native platforms — Britive, Apono, StrongDM, Teleport — were built to eliminate standing credentials through ephemeral provisioning. PAM-with-JIT platforms — CyberArk, BeyondTrust, Delinea — were built for credential management and session brokering, then added JIT workflow layers on top. Both claim zero standing privilege. They achieve it differently, and the right choice depends on what your environment can support.

What each architecture requires

JIT-native ephemeral provisioning requires an infrastructure that can absorb ephemeral IAM semantics. AWS IAM, Azure RBAC, GCP IAM, and Kubernetes RBAC can all accept time-limited role grants or certificate-based credentials that expire. A cloud-native JIT platform provisions an IAM entity directly in the cloud control plane, then deletes it on expiration. The security property is categorical: the credential does not exist outside the session window.

This model works where the infrastructure participates in modern IAM. It does not work for a 15-year-old Oracle database running on-premises that authenticates with a static password file, an Active Directory workload that does not support ephemeral role grants, or industrial infrastructure that has no concept of time-limited API tokens. For those targets, the vault-centric model is the only viable architecture that provides any JIT capability at all.

Vault-centric PAM with JIT requires a vault that can reach all the targets in scope, a proxy that can broker sessions through that vault, and administrative overhead to manage the vault as a persistent system. The JIT property comes from time-limiting session checkouts and automating credential rotation, not from eliminating the credential's existence. A vaulted password still exists; it is just not checked out continuously. If the vault is compromised, or the vault proxy is available but the session timer is mismanaged, the standing credential remains reachable.

The vault-centric model covers the targets that JIT-native cannot: legacy on-premises databases, AD-authenticated servers, industrial systems, and any target that does not participate in cloud IAM. That coverage argument is the vault's strongest case.

Detailed comparison

Dimension	JIT-Native (Britive / Apono / StrongDM)	PAM-with-JIT (CyberArk / BeyondTrust / Delinea)
Security Properties
Credential existence	Credential does not exist outside the session window	Credential exists in vault; session checkout is time-limited
Zero standing privilege (cloud)	Structural — IAM entity is created and deleted per session	Workflow-enforced — vault checkout window limits exposure duration
Vault compromise risk	No central vault to compromise for cloud targets	Central vault is an attack target; vault security is a primary operational concern
Coverage
Cloud IAM (AWS/Azure/GCP)	Native; ephemeral provisioning directly in cloud control plane	Available via API integrations; not the native model
On-premises databases and servers	Limited or absent (StrongDM via proxy is the exception)	Core coverage; vault-proxy model designed for on-premises targets
Active Directory workloads	Limited; requires AD integration layer	Deep AD integration; strongest for AD-centric enterprises
Legacy infrastructure	Generally incompatible with ephemeral token model	Vault proxy can reach targets that do not support modern IAM
Deployment and Operations
Time-to-value	Faster for cloud-native environments; no vault infrastructure to stand up	Significant deployment effort; professional services typically required
Ongoing operational overhead	Lower; no vault to maintain, rotate, and manage	Higher; vault management is an ongoing operational function
Session recording and audit	Varies by platform; StrongDM proxy provides full recording	Session recording is typically native and comprehensive in mature PAM deployments
Hybrid estate coverage	Partial; cloud covered, on-premises requires a second tool or workaround	Designed for hybrid; one platform for both cloud and on-premises

When each wins

JIT-native wins when

Primary infrastructure is cloud-native (AWS, Azure, GCP) and participates in modern IAM
Zero standing privilege for cloud workloads is the primary security goal
No legacy on-premises infrastructure that requires vault-proxy coverage
Deployment simplicity and faster time-to-value are requirements
The operational overhead of running a persistent vault is unwanted
Developer experience and low-friction JIT workflows are priorities

PAM-with-JIT wins when

Hybrid estate with on-premises databases, servers, and AD workloads that cannot support ephemeral tokens
Compliance requirements mandate centralized session recording for all privileged access
Existing PAM investment creates migration cost that outweighs architectural preference
Legacy infrastructure is a primary target and cannot be excluded from JIT scope
Vendor remote access management is a priority use case

The hybrid estate reality

Most large enterprises land in the middle: significant cloud workloads that can support ephemeral JIT, and significant on-premises and legacy infrastructure that cannot. Working out what that means in practice, what replacement actually costs, when an overlay on existing PAM makes more sense than a rip-and-replace, and how to map your environment before a sales cycle starts, is covered in full in PAM Replacement vs. JIT Overlay.

Finding

The architecture question precedes the vendor question. Buyers who have not answered "what infrastructure do we actually need JIT for, and can that infrastructure support ephemeral token provisioning" before evaluating vendor features are evaluating the wrong thing. Map the environment first. The architecture decision follows from the environment. The vendor decision follows from the architecture.
