For years, teams have relied on bastion hosts as the single guarded doorway to their infrastructure. They created friction, slowed deployments, and demanded constant maintenance. That pattern made sense once. It doesn’t fit the pace or security needs of continuous integration today. The rise of modern development means every delay compounds, every manual approval adds drag, and every layer that isn’t automated becomes a vulnerability.
A bastion host replacement for continuous integration is not just an upgrade in tools—it’s a change in architecture. Instead of central choke points, you get secure, ephemeral access that spins up on demand and shuts down instantly when the job completes. The attack surface is smaller because there’s nothing to keep online. Secrets are managed automatically. Access is scoped to the job and the moment it runs. Zero standing credentials. No idle servers.
In high-speed CI pipelines, bastion hosts act like permanent fixtures in a world that rewards the temporary. They assume static infrastructure, but most pipelines now touch dynamic environments—containers, serverless stacks, ephemeral VMs—that live for minutes. Replacing bastion hosts with ephemeral, policy-driven gateways means every build, test, and deploy can work against production-grade targets without punching permanent holes in the network.
