Just-in-time (JIT) access reduces the risk of credential abuse by eliminating always-on privileged access to devices and network-connected assets. Instead of leaving elevated permissions continuously available, JIT grants privileged access only when it’s needed and for a limited period of time. This reduces the pool of standing credentials attackers can steal and use for initial access, privilege escalation, lateral movement, ransomware, or cyber sabotage.
The stakes are significant. Microsoft’s 2025 Digital Defense Report found that access brokers used credential-based attacks in 80% of initial-access cases. IBM’s 2026 Cost of a Data Breach Report found that breaches involving valid account abuse cost an average of $5.07 million and took 243 days to identify and contain. IBM also found that excessive privileges and poor role management increased average breach costs by $177,313.
Reducing standing privileges and limiting reusable credentials directly shrinks this attack surface. JIT access gives organizations a way to tightly govern who receives privileged access, what they can access, and how long that access remains available.

JIT Access and Zero Standing Privilege
Just-in-time access grants users only the privileges they need, only for as long as they need them, eliminating the standing accounts attackers rely on. This is the practical application of Zero Standing Privileges (ZSP): no account carries privileged access by default, closing off a primary ransomware and sabotage entry point.
Instead of leaving accounts active and at risk of being compromised, organizations can use an access control solution to grant a local or remote user the level of access they need to a specific resource for a limited time period. The user must request access and receive authorization, as well as being required to authenticate into the asset itself. To maximize its effectiveness, JIT access must be layered with other protections, such as MFA for remote access, as part of an overall defensible architecture.
By requiring MFA at multiple steps, organizations can ensure that access to critical assets and applications can be granted in ways that are necessary for the organization, without accepting undue risk that those privileges will be compromised by an adversary.

Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC)
Just-in-time access determines when privileged access should be available. RBAC and ABAC help determine what level of access a user or identity should receive.
Role-based access control (RBAC) assigns permissions based on a user’s role, while attribute-based access control (ABAC) can incorporate additional context such as location, recent behavior, device posture, indicators of compromise (IOCs), or other risk signals. This means that even a user with a privileged role does not automatically receive unrestricted access.
Together, RBAC and ABAC allow organizations to tailor both the scope and duration of JIT access based on the identity, task, resource, and surrounding risk context.
Ephemeral Accounts
Some JIT access solutions create ephemeral accounts that exist only for the duration of an approved task. These accounts are provisioned with the required privileges and time limits, then automatically deactivated when the approved access window ends.
Other approaches control access to persistent accounts using safeguards such as password rotation, MFA, and time-bound authorization. In either model, the objective is the same: reduce or eliminate privileged access that remains continuously available.
This supports the goal of Zero Standing Privileges (ZSP), in which privileged access is granted only when needed rather than being permanently assigned to an account.
Zero Trust and the Principle of Least Privilege
JIT access, RBAC, and ABAC work together to put Zero Trust privileged access into practice. Each request for elevated access can be evaluated based on who or what is requesting access, the resource being accessed, the privileges required, and the context surrounding the request.
This directly supports the principle of least privilege: users and non-human identities receive only the minimum level of access required to complete an approved task, and only for as long as that access is needed.
Break-Glass Access: Handling Emergency Exceptions
Break-glass access provides a controlled emergency path to critical systems when following the normal JIT approval process would create an unacceptable delay. Emergency access should still be authenticated, logged, time-bound, and subject to review so that it remains a governed exception rather than a standing bypass.
Privileged Session Management (PSM)
Just-in-time access complements another vital security practice: privileged session management (PSM). With JIT, the organization controls when a user has access. With PSM, the administrator or security team can observe what’s happening during sessions in real time, and terminate or change permission levels on the fly to protect against risk.
PSM is one of the core capabilities to look for in a privileged access management (PAM) solution. The combination of JIT access and PSM is especially valuable in the context of securely bringing in third parties or contractors for specific tasks. When someone from outside your company needs time-limited privileged access for a specific task, the ability to monitor, record, and even terminate the session in progress is an important security control.
Many enterprises rely heavily on third-party service providers, software vendors, contract employees, and other outsiders who want remote access for management and monitoring. Securely enabling vendor remote access is an increasingly urgent security requirement.
How Xage Enables Just-in-Time Privileged Access
Xage helps organizations reduce standing privilege by giving users access to critical resources only when they need it and for only as long as necessary. Organizations can apply just-in-time access across IT, OT, and cloud environments while maintaining granular control over employees, administrators, contractors, vendors, and other privileged users.
Xage combines JIT access with policy-based access controls, multi-layer MFA, and privileged session management. This allows organizations to control which resources users can access and for how long, while maintaining visibility and control throughout privileged sessions. Security teams can monitor activity and terminate sessions when necessary, helping limit the impact of compromised credentials or risky behavior.
Together, these capabilities help organizations enforce least privilege and move toward Zero Standing Privileges without sacrificing the access administrators and third parties need to perform legitimate work. Xage provides a consistent approach to governing privileged access across converged IT, OT, and cloud environments.

Frequently Asked Questions
What is the difference between JIT access and standing privileged accounts?
Standing privileged accounts provide continuous administrative access, even when it isn’t needed. Because they remain active, they are a frequent target for attackers seeking to steal credentials, escalate privileges, and move laterally across an environment.
Just-in-time (JIT) access eliminates these always-on privileges by granting users only the permissions they need for a specific task and only for a limited period of time. Once the approved time expires, privileged access is automatically removed, significantly reducing the attack surface and supporting Zero Standing Privileges (ZSP).
What is break-glass access?
Break-glass access is an emergency access mechanism that allows an authorized user to access a critical system when the normal approval workflow would pose unacceptable operational, safety, or security risks.
In a Zero Trust privileged access model, break-glass should not become a permanent bypass around JIT access. It should still require strong authentication, be limited to the minimum access needed, expire automatically, and generate a complete audit trail for post-incident review. Used properly, break-glass access gives organizations a governed emergency override without reintroducing always-on privileged accounts.
What is Zero Trust privileged access?
Zero Trust privileged access applies the Zero Trust principle of least privilege to administrative access. Rather than assuming privileged users should always be trusted, every request for elevated access must be verified, authorized, and limited to the minimum permissions required.
In practice, Zero Trust privileged access combines just-in-time access with role-based access control (RBAC), attribute-based access control (ABAC), strong authentication, and continuous enforcement. Users receive only the privileges they need, only when they need them, and only for approved resources.
How does JIT access work with privileged session management?
JIT access controls when privileged access is granted, while Privileged Session Management (PSM) controls what happens after access begins.
After a user receives time-limited JIT access, PSM enables security teams to monitor, record, and, if necessary, terminate the session in real time. Together, JIT and PSM reduce standing risk while providing visibility and control over privileged activity, particularly for administrators, contractors, and third-party vendors performing sensitive tasks.
Is JIT access required for Zero Trust compliance?
While no single framework mandates just-in-time access in every environment, JIT is widely recognized as a best practice for implementing Zero Trust and the principle of least privilege.
Organizations can reduce risk by eliminating standing privileged accounts and granting temporary, verified access only when needed. Combined with RBAC, ABAC, MFA, and privileged session management, JIT helps organizations operationalize Zero Trust by minimizing unnecessary privileges and limiting opportunities for credential abuse and lateral movement.
