Clientless and agentless, for every system you run.
Teleport is a broad identity platform built on short-lived certificates and agents. GSR Access Gateway is a self-hosted gateway that needs nothing on your systems and nothing on users' devices, including Telnet systems.
Where Teleport is strong
a broad resource range (Kubernetes, databases, cloud consoles, web apps, MCP), a certificate-based model without static passwords, BPF session recording on Linux, a Cloud option, and a large community [T1][T8].
| Teleport | GSR Access Gateway | |
|---|---|---|
| Software on Linux servers | Teleport SSH Service by default; agentless OpenSSH mode loses session sharing and BPF recording [T4] | None. Standard SSH |
| Linux desktops | Linux Desktop Service runs on the host [T12] | None: RDP (e.g. xrdp) |
| Telnet | Not documented [T1] | Yes |
| SSO in the free edition | Community: GitHub SSO only [T1] | OIDC, SAML and LDAP/AD in every deployment |
| Session sharing | Enterprise only (observer/peer/moderator) [T1][T10] | Included |
| Ending sessions with a message | Locks, with optional message (Enterprise) [T11] | Terminate with required reason (included) |
| Command blocking | Not documented; BPF recording "does not provide a secure environment on its own" [T8] | Block or alert on terminals |
| Legacy encodings / RTL | Not documented | 50 encodings, right-to-left display |
| Credentials | Short-lived certificates, no password vault [T5] | Encrypted vault with rotation, or your external vault; one-time credentials for ephemeral environments |
| Licensing | Enterprise by sales. Community binaries free only under 100 employees and US$10M revenue [T1] | Annual subscription by blocks of systems |
