You Can’t Secure What You Can’t See

Orphaned accounts, untracked sudo rules, SSH key sprawl — the identity layer on Linux is invisible to your existing security stack. LinuxGuard maps every privilege path so you can eliminate blind spots before attackers exploit them. Our 28-day Linux Identity & Security Audit produces a complete privilege map, risk-ranked findings, and board-ready compliance evidence for NIS2, DORA, SOC 2, and CIS — so you walk away with answers, not just data.

Know every privilege path — See exactly who can sudo to root, which SSH keys grant access, and where service accounts have accumulated excessive permissions
Prove compliance continuously — Generate auditor-ready evidence for NIS2, DORA, SOC 2, CIS, and ISO 27001 from your actual Linux configuration, not spreadsheets
Reclaim wasted infrastructure — Identify over-provisioned servers and idle workloads with eBPF-powered utilization intelligence that quantifies savings in dollars
Reduce risk and spend together — One Linux-native platform that eliminates identity blind spots and right-sizes infrastructure simultaneously

Linux identity audit — fixed scope, fixed fee

Three Pillars. One Platform.

Comprehensive Linux Intelligence

LinuxGuard combines Zero Trust security, compliance automation, and compute efficiency into a unified, Linux-native platform. Built by experts, for Linux teams.

Zero Trust for Linux

Continuous identity visibility and least privilege enforcement

See exactly who can sudo to root on every server — eliminate privilege blind spots in hours, not months
Detect unauthorized SSH key additions and orphaned accounts the moment they appear
Enforce least privilege without disrupting operations — actionable remediation, not just alerts

Compliance Readiness for Linux

Continuous compliance monitoring and audit-ready evidence

Generate auditor-ready evidence for SOC 2, ISO 27001, NIS2, and DORA from actual Linux configuration
Reduce audit preparation from weeks of manual gathering to a single structured export
Prove continuous compliance posture to boards and regulators with historical trend data

Compute Efficiency for Linux

Infrastructure optimization and cost intelligence

Identify 15-35% infrastructure savings by finding over-provisioned servers and idle workloads
Quantify every optimization opportunity in dollars — prioritize by business impact, not guesswork
Right-size infrastructure with eBPF-powered utilization intelligence that sees true resource pressure

Why Linux identity is your most dangerous blind spot

Generalist security tools were built for Windows-first environments — they scan ports and patch CVEs, but they cannot see the Linux-native identity artefacts that attackers exploit first: NOPASSWD sudo rules, shared SSH keys, orphaned service accounts, and PAM configuration drift. Privilege accumulates silently between manual reviews, and most organisations have no way to detect it until something goes wrong. According to CrowdStrike's 2025 report, 79% of attacks on Linux use no malware at all — attackers simply log in with valid credentials that should have been revoked. NIS2 and DORA now require demonstrable identity controls and audit trails, and spreadsheet-based reviews no longer satisfy auditors. Closing this gap requires a Linux-native platform that understands how Linux identity actually works — not a generalised scanner retooled for a different operating system.

Linux Is Different

Your Security Tools Were Never Built for Linux Identity

Your SIEM sees logs. Your EDR watches processes. Your CSPM scans cloud configs. None of them map the identity layer where attackers actually operate on Linux -- the sudo rules, PAM configs, SSH keys, and service accounts that define who can do what.

SIEMs capture authentication events but miss privilege relationships -- they see who logged in, not what they can do
EDR tools monitor runtime behavior but are blind to identity configuration -- orphaned accounts and excessive sudo rules persist undetected
CSPM tools scan cloud IAM but skip OS-level identity -- local users, groups, and SSH keys exist outside their scope
LinuxGuard maps every identity, privilege path, and access relationship across your entire Linux estate

First Audit Findings

What LinuxGuard Discovers in Your First Audit

Every Linux estate we audit reveals the same critical identity risks. These are the four categories that create the most exposure.

Orphaned accounts

Local users with no owner, no login history, and no last authentication -- still active, still capable of escalating.

Excessive sudo privileges

Broad NOPASSWD rules and ALL permissions granted temporarily, never revoked -- bypassing the last authentication checkpoint.

SSH key sprawl

authorized_keys files with unknown public keys, no rotation policy, and shared keys across users and systems.

Privilege creep

Group memberships accumulated over years of role changes, never reviewed, carrying far more access than the role requires.

Expert Services

Implementation & Advisory Support

LinuxGuard is backed by an expert-led Linux Identity & Security Audit service. A fixed-scope, 28-day engagement that maps every identity and privilege path across your Linux estate, identifies the drift that creates real risk, and delivers compliance-ready evidence for boards and auditors. Led by Peter Cummings, with 20+ years of IAM experience at Mastercard, EY, Lonza, and UBS. The audit closes with a least-privilege implementation roadmap and remediation guidance your engineering team can act on immediately — without a lengthy professional services engagement.
