Your security stack is strong.Linux identity completes it.
Every identity on your Linux estate — human, non-human, containerised, agentic — should be known, governed, and continuously assured. For most organisations, it isn't. LinuxGuard changes that.
Built by practitioners with 20+ years inside Mastercard, UBS, EY, and the UK Government — who saw this blind spot from the inside, and built the tool that fixes it.
Why Linux identity is a dangerous blind spot
Linux is the foundation of the modern enterprise. Yet most organisations have little to no visibility into which identities can do what across their Linux estate — and little to no awareness that this is a critical issue. Existing tooling doesn't cover it. LinuxGuard was built specifically to fix this.
The blind spot
Attackers don't need malware on Linux — they use valid credentials that should have been revoked.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 accumulation problem
Privilege creep accumulates silently between manual reviews — orphaned accounts, NOPASSWD sudo rules, shared SSH keys. Most organisations have no way to detect it until something goes wrong.

The compliance pressure
NIS2 and DORA require demonstrable identity controls and continuous audit trails. Spreadsheet reviews no longer satisfy auditors.

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
Agentless 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.

View CertificationWhy 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.
