Bastion hosts promised secure entry points to private infrastructure. In practice, they became choke points—slowing deployments, complicating debugging, and adding one more credential to protect. SSH keys expire. VPNs drop. People wait for access they should already have. The result: less time shipping, more time managing gates.
A better way exists. Modern infrastructure access does not require a static bastion host sitting in the middle of your network. Remote computing has changed. Cloud-native systems can deliver strong authentication, granular permissions, and audit trails without relying on a single exposed server. An alternative should reduce complexity, not replace it with a different bottleneck.
The core problems with bastion hosts are predictable. They introduce central dependencies. They rely on manual provisioning. They require constant patching. They are blind to the context of the user request. If your stack spans multiple regions, accounts, or cloud providers, the brittleness multiplies. Bastion host alternatives use ephemeral access, identity-aware proxies, and automated policy enforcement to connect people to what they need—without maintaining a constant, reachable target on the internet.
