LinuxGuard vs Teleport for Linux: what is visible, and what is provable.

Teleport is a modern infrastructure access platform built on short-lived certificates. LinuxGuard is a next-generation, Linux-native PAM that maps and governs what every identity can do on the host — including the local accounts, sudo rules and keys that never touch a proxy. This page compares the two on the axis that decides your Linux exposure.

LinuxGuard is a next-generation, Linux-native privileged access management platform built for the agentic estate. Where a vault or a session broker governs the access it brokers, LinuxGuard maps what every identity can do on every host — human, service account or the accounts AI agents authenticate as — flags every change as it happens, and contains a compromised identity behind an approval gate. It does not vault credentials or record sessions.

LinuxGuard is best for

You need to know what every identity can do on every Linux host today — before, beside or instead of a broker — and to prove it to an auditor.
Your estate carries years of sudo rules, SSH keys and service accounts that nobody has mapped, and automation and AI agents now use those paths faster than any review.
You are evaluating Teleport and want your actual baseline first, or you have deployed it and an audit still found findings in the Linux identity layer it does not see.
You are preparing for NIS2, DORA, SOC 2, PCI DSS or ISO 27001 and need Linux access-control evidence in the form the assessor tests, exported from a live inventory.
You need containment that is one approval away — lock the account, revoke sudo, disable the key, terminate the session — rather than a ticket queue.

Choose Teleport if

You want zero-standing-privilege, certificate-based access for developers to SSH, Kubernetes, databases and web applications behind one access plane.
Your estate is cloud-native and the access pattern is developer-to-infrastructure, where a proxy can sit in front of every session.
You want cryptographic audit trails of who accessed what through the proxy, with a strong developer experience.

Teleport on Linux, as published in our comparison

What it is: Teleport is a modern infrastructure access platform built around short-lived certificates and just-in-time access. Rather than managing standing credentials, Teleport issues cryptographic certificates scoped to specific tasks and contexts, which expire automatically. It supports SSH, Kubernetes, databases, and web applications behind a unified access plane.
What it does well on Linux: Teleport’s approach to Linux SSH access is genuinely progressive. By replacing long-lived SSH keys with short-lived certificates, it eliminates the SSH key sprawl problem for sessions that go through Teleport. Its audit log provides a complete record of who accessed what server, when, and what commands were run. For cloud-native environments with a developer access use case, Teleport is elegant.
What it does not do: Teleport governs access that flows through its proxy. It does not inventory the Linux identity topology that exists outside its control plane — the local accounts, sudo rules, service account memberships, and authorized_keys entries that were there before Teleport was deployed, or that exist on systems not yet enrolled. It does not produce compliance evidence for NIS2 Article 21 or DORA ICT risk management controls that require evidence of your overall access control posture — not just the sessions recorded through a proxy.
Deployment reality: Teleport is primarily designed for developer-to-infrastructure access patterns in cloud-native environments. It is an excellent tool for its intended use case. Retrofitting it across a large, heterogeneous Linux estate — particularly one with legacy systems, embedded Linux, or OT-adjacent infrastructure — is complex and often impractical.

Using Teleport and LinuxGuard together

Teleport and LinuxGuard are not always alternatives. The common mistake is deploying a broker or a vault without first mapping what you have: you end up governing a known subset while the sudoers files, orphaned accounts, shared SSH keys and service-account privilege that existed before the deployment remain your actual exposure.

Map first with LinuxGuard, remediate the worst findings directly, then put Teleport where it adds value, and keep LinuxGuard watching the estate for the paths that open up afterwards. The sequencing is set out in the full Linux PAM comparison.

Frequently Asked Questions

Does LinuxGuard replace Teleport?

No. Teleport governs and records the sessions that go through its proxy and can surface unmanaged keys in that estate; LinuxGuard maps what every identity can do on the host once it is there — sudo rules, local and service accounts, PAM chains, paths to root — however it arrived. They answer different questions and work side by side. The full comparison covers eight platforms.

We already use Teleport. What would LinuxGuard find?

Whatever is on the hosts that never went through the proxy: local accounts, authorized_keys entries that predate Teleport, NOPASSWD sudo rules, service accounts and the reach they have accumulated, and the paths to root those things add up to. The pilot maps all of it in 60 days.

Which should we deploy first?

Map first. Knowing which hosts, accounts and keys exist outside the proxy tells you what Teleport needs to enrol and what needs closing before it does. The pilot gives you that baseline and the compliance evidence at the same time.
