A bastion host is often called the secure gateway to your infrastructure. But a single, exposed point of entry is a standing invitation to attackers. Once they know where the bastion host lives, their job is to wait for the right weakness — a leaked key, a missed patch, a careless config. The result: a clean shot past your defenses.
Data breaches involving bastion hosts are not rare. They show up in incident reports, postmortems, and quiet boardroom meetings. The problem is not just the software. It’s the architecture. A bastion host concentrates your risk. One failure and the wrong hands get access to everything it protects.
An alternative to the bastion host model removes the idea of a permanent gateway. No static endpoints. No standing credentials. No host sitting in the open, visible to anyone scanning the network. Instead, connections are brokered just-in-time, with short-lived access that ends the moment it’s no longer needed. This reduces the attack surface from something measurable to something fleeting.
