Bastionhost is a cloud-native privileged access management (PAM) service that centralizes control, auditing, and governance of operations and maintenance (O&M) access to your servers and other assets.

What Bastionhost does

  • Control who can access what — Grant and revoke access to servers and assets from a single location, without distributing SSH keys or opening inbound firewall ports.

  • Record every session — Capture real-time video recordings of all O&M sessions and play them back for compliance reviews.

  • Audit all activity — Maintain a tamper-proof session audit trail that tracks every command and operation.

  • Require approval for sensitive operations — Route high-risk access requests through an approval workflow before a session starts.

  • Store credentials securely — Use credential hosting to manage and inject SSH and Remote Desktop Protocol (RDP) credentials without exposing them to operators.

  • Enforce multi-factor authentication (MFA) — Add a second layer of identity verification at session initiation.

Who should use Bastionhost

  • Security administrators who need to enforce least-privilege access policies, eliminate standing credentials, and satisfy compliance requirements.

  • O&M administrators who manage day-to-day access to servers and assets, and need a single place to grant, revoke, and monitor permissions across teams.

  • Auditors who review session recordings and audit logs to investigate incidents or demonstrate compliance without needing direct system access.

  • IT compliance officers who require documented evidence of who accessed which asset, when, and what they did — with session-level granularity.

How it works

Bastionhost mediates every O&M session through a controlled access plane:

  1. Authentication — The operator logs on to Bastionhost using their account credentials, with MFA enforced if configured.

  2. Authorization — Bastionhost checks the operator's permissions against the configured policies and, for sensitive assets, triggers an approval workflow.

  3. Connection — After authorization is granted, Bastionhost establishes the session to the target asset using stored credentials. The operator never sees the underlying SSH key or RDP password.

  4. Recording and monitoring — Bastionhost records the session in real time and streams it to monitoring consoles so administrators can observe live sessions.

  5. Audit — After the session ends, the full session audit record — including real-time video recording and command logs — is available for review and playback.
