Bastion hosts were supposed to prevent that. For decades they stood as the gatekeepers to production. They logged commands, tracked sessions, and claimed to keep the bad actors out. But the truth is that bastion hosts are brittle, slow to maintain, and blind to the full picture of what happens inside a session. Traditional bastion logging captures commands, not context. It tells you what was typed but not what was seen. It cannot replay the session in detail. And every bastion host is yet another piece of infrastructure to patch, monitor, and harden.
Session replay has changed the equation. Modern session replay captures every keystroke, every command, every terminal output—exactly as it unfolded. It creates a verifiable, searchable, video-like record you can review anytime. It’s more than logging. It’s visibility without compromise. A true replacement for bastion hosts doesn’t just lock the door. It shows you what happens after someone walks through it.
Replacing a bastion host with session replay technology removes an entire class of risk. There are no long-lived SSH keys to leak. No server to expose from a public subnet. Access can be ephemeral, tied to identity, and revoked instantly. Session replay gives full accountability for every action, making audits straightforward. It also aligns with security frameworks like SOC 2, ISO 27001, and HIPAA.
