Linux Identity Security: know who can do what, right now
Years of sudo rules, SSH keys and service accounts have built paths to root across your Linux estate that nobody has mapped. Automation and AI agents now find and use them faster than any review. LinuxGuard maps every one and flags every change as it happens.
Built by practitioners with 20+ years inside Mastercard, EY, UBS, Lonza, and UK Government agencies — who saw this blind spot from the inside, and built the tool that fixes it.
The unmapped Linux identity layer
Linux is the foundation of the modern enterprise. Most organisations already sense that Linux identity isn't fully covered — they're right. Here's what's actually happening below the layer your existing tools inspect.
247
orphaned accounts discovered in a 412-server estate
The accumulation problem
The teams that catch privilege creep early detect it continuously — orphaned accounts, NOPASSWD sudo rules, shared SSH keys — instead of finding out when something goes wrong. None of it was created by an attacker or an agent. It is what years of deployments, migrations and emergency fixes leave behind.

of modern enterprise attacks use no malware
Beneath SIEM, EDR and cloud IAM
Attackers don't need malware on Linux — they use valid credentials that should have been revoked. SIEM, EDR, and CSPM tools miss Linux-native identity artefacts entirely.

The compliance pressure
Teams that map Linux identity controls now arrive at audit cycles ready — rather than building the evidence after the fact. NIS2 and DORA require demonstrable controls; LinuxGuard generates them continuously.

From First Discovery to Continuous Assurance
LinuxGuard holds the full picture and the smallest detail — giving your team the clarity to act with nothing in your Linux estate left unaccounted for.
- 1
Discovery
Fast scan of every user, group, SSH key, sudo rule, PAM config, and service account across your Linux fleet.
- 2
Identity Inventory
A complete, structured identity map — every account, every privilege path, every access relationship — built automatically.
- 3
Risk Prioritisation
Findings scored and ranked so your team knows exactly which gaps to close first — no alert fatigue, no guesswork.
- 4
Continuous Assurance
Drift detection runs continuously — every new account, changed permission, or SSH key addition is flagged before it becomes a risk.

Why LinuxGuard
Your SIEM, EDR, and cloud tools weren't built for Linux identity
Generalist security platforms watch the network, the endpoint, and the cloud — but not the artefacts that decide who can actually do what on a Linux host. Sudo rules, SSH keys, PAM chains, and orphaned service accounts live below the layer SIEM, EDR, and CSPM tools inspect — exactly where privilege drift accumulates and attackers move once they have valid credentials.
LinuxGuard was built for that layer from the ground up, not adapted from a Windows-first agent or cloud-first scanner. It maps every privilege path from the filesystem, audit logs, and PAM configuration on each host, then flags drift the moment it appears.
Network traffic, endpoint processes, and cloud configuration — the perimeter and the workload, but not the identity artefacts on the Linux host itself.
NOPASSWD sudo entries, shared and stale SSH keys, PAM chain changes, and service accounts that outlived the workload they were created for.
A continuous, host-level identity map — every privilege path enumerated, every drift event flagged, every account accounted for across your estate.
Know your Linux estate completely.
Every identity, every privilege, every connection — known, governed, and continuously assured. Request a Founding Pilot, or explore the platform first.
