Your Bastion Host Is the Most Dangerous Server in Your Network

Bastion hosts, traditionally used as hardened gateways for administrative access, can become high-value single points of failure in modern distributed environments, where remote workers, multicloud infrastructure, and varied management protocols complicate their operation. The text cites Microsoft’s 2025 critical Azure Bastion vulnerability as an example of how compromise of such a gateway can expose every reachable backend system, while also highlighting common issues including delayed patching, credential theft, weak identity attribution, difficult high availability, and excessive logging noise. It argues that a zero-trust approach should eliminate publicly accessible SSH endpoints, authenticate sessions to individual users through an identity provider, and enforce narrowly scoped, session-level policies rather than broad network access. Twingate Privileged Access for SSH is presented as an alternative architecture in which a client, outbound-only connector, controller integrated with an existing identity provider, and SSH session gateway provide authenticated, logged access without a public bastion or exposed SSH port. The proposed migration involves gradually routing hosts and users through the new access model, validating policies and logging, then retiring the bastion, while acknowledging that organizations exchange reliance on a bastion host for dependence on Twingate’s connector and controller infrastructure.
