Every request for access turns into a ticket. Each ticket turns into a wait. And every wait adds friction to teams who should be shipping, not begging for credentials. Bastion hosts were built for another era — static networks, fixed perimeters, and always-on sessions that stay open far too long. They guard entry but also bottleneck it.
There is another way. Just-in-time access replaces the always-on gate with ephemeral, time-bound permissions. Instead of managing and patching a bastion box, you generate secure access only when it’s needed. No VPN switch. No permanent SSH keys. No lingering ports.
With just-in-time access, authorization is not a one-time decision. It is dynamic. A request is approved, short-lived credentials are issued, and they expire automatically. Attack surface drops. Audit logs stay clean. Least privilege stops being theory and becomes the default.
