A bastion host once felt like the clean, simple answer to secure remote access. One hardened server, one entry point, all requests funneled through it. But today, the cracks show. Static IP whitelists. Manual key rotation. Latency from a single choke point. Scaling it means wrestling with complexity, and the moment you need granular, temporary, or user‑specific access, you start building brittle tooling on top.
Many teams tighten security with GPG encryption layered on top of SSH, thinking it will plug the gaps. But adding GPG to a bastion host workflow often amplifies friction. Keys pile up. Revocations lag. Onboarding turns into a ritual of command‑line incantations and documentation archaeology. Meanwhile, every extra step drags down the pace of development and increases the surface for human error.
A modern alternative ditches the bastion host entirely. You centralize authentication, not traffic. Users get secure, ephemeral credentials tied to their identity. Access is just‑in‑time, logged, and auditable by default. GPG encryption can be integrated at the edge, where it belongs, without the bottleneck of a static choke point in the middle of the network. The infrastructure stays hidden from the public internet, and your attack surface shrinks to almost nothing.
