Just-In-Time Access Approval with Outbound-Only Connectivity

The request popped up in the console: access needed, approve or deny. No warning. No time to waste.

Just-In-Time Access Approval with outbound-only connectivity is how you take control of that moment. It removes persistent credentials, kills idle permissions, and limits the blast radius if something goes wrong. Every request is temporary. Every session is on-demand. Nothing is left open when not in use.

In a Just-In-Time flow, developers or services request access only when they need it. An approval system—often integrated with chat, ticketing, or custom APIs—validates the request. Once approved, access is granted for a short, fixed period, then revoked automatically. The key is combining it with outbound-only connectivity. This means resources never expose open inbound ports. Agents or connectors initiate all network communication from inside the protected environment, pushing events and logs out, and pulling commands in only when authorized.

Outbound-only connectivity reduces the attack surface to near zero. No public endpoints. No inbound firewall exceptions. Threat actors scanning the network find nothing to target. Combined with Just-In-Time granting, the result is a system that is both hardened and flexible—security without bottlenecks.

Implementing this setup requires an approval workflow, a policy engine, and an outbound connector. The workflow ties to your identity provider for authentication, the policy engine enforces conditional rules, and the connector maintains outbound sessions. You monitor and log every action for audit compliance. Requests expire by default, so stale access disappears automatically.

This approach meets modern compliance requirements for least privilege and zero trust, while staying developer-friendly. There are no VPNs to manage, no static keys to rotate, and no blind spots in monitoring. You know exactly who accessed what, when, and why—and you know they can’t get in again without a new approval.
