Identity-First Security Platform

Three Pillars of Linux Intelligence

LinuxGuard delivers identity-first security for Linux through three integrated value pillars: zero trust for Linux, automated compliance, and compute efficiency. Every capability is Linux-native, built by experts who understand your infrastructure.

Zero Trust for Linux

Eliminate privilege drift and identity-based threats with continuous monitoring of users, groups, sudo rules, and SSH keys across your entire Linux infrastructure. Know who can do what, everywhere.

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

Identity & Privilege Mapping
Complete visibility into users, groups, sudo rules, and SSH keys across every Linux server. Know who can do what, everywhere.
Privilege Drift Detection
Spot dangerous sudo rule changes and forgotten elevated access before attackers exploit them. Continuous monitoring replaces periodic audits.
Service Account Governance
Track non-human identities across your Linux estate. Identify over-privileged service accounts and API keys that bypass governance.
SSH Key Management
Inventory all SSH keys, identify orphaned credentials, and detect unauthorized key additions. Eliminate the access backdoors auditors miss.
PAM Configuration Monitoring
Real-time visibility into PAM module changes. Detect authentication bypasses and policy violations as they happen.
Least Privilege Enforcement
Automated identification of excessive privileges with actionable remediation. Build zero trust without manual access reviews.

Compliance Readiness for Linux

Automate compliance validation across CIS Benchmarks, NIST 800-53, PCI DSS, HIPAA, SOC 2, ISO 27001, NIS2, and DORA. Transform quarterly audit prep from months to minutes with continuous evidence collection.

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

CIS Benchmark Validation
Automated validation against CIS Benchmarks for Linux. Continuous compliance replaces manual quarterly audits.
Multi-Framework Coverage
Single-pane compliance across NIST 800-53, PCI DSS, HIPAA, SOC 2, ISO 27001, NIS2, and DORA. Map controls once, report everywhere.
Configuration Baseline Drift
Real-time detection of deviations from approved baselines. Know within seconds when servers drift from compliance.
Audit Evidence Collection
Automated evidence gathering for compliance audits. Export audit-ready reports without manual spreadsheet work.
Compliance Trending & History
Track compliance posture over time. Demonstrate continuous improvement to auditors with historical data and trend analysis.
Remediation Guidance
Actionable fix recommendations for every compliance gap. Cut remediation time with step-by-step guidance aligned to your Linux distribution.

Compute Efficiency for Linux

Reclaim 15-35% of infrastructure spend by identifying over-provisioned servers, idle workloads, and resource waste. Linux-native PSI monitoring reveals true resource contention with dollar-value impact analysis.

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

Efficiency Scoring Engine
0-100 score per server based on CPU pressure, memory utilization, and disk I/O. Quantify waste and rightsizing opportunities at a glance.
Rightsizing Recommendations
Automated instance rightsizing suggestions with cost impact analysis. Identify over-provisioned servers draining your budget.
Idle Workload Detection
Find zombie processes, unused containers, and idle VMs consuming resources. Reclaim capacity without impacting active workloads.
Storage Growth Intelligence
Track directory-level growth velocity. Predict storage needs and identify log bloat before it triggers incidents.
CPU Pressure Analysis
Linux-native PSI (Pressure Stall Information) monitoring. Understand true resource contention, not just utilization averages.
Cost Impact Quantification
Dollar-value estimates for every efficiency finding. Prioritize optimizations by business impact, not just technical metrics.
Linux Is Different

Why Generic Tools Miss What Matters on Linux

Enterprise security stacks are built for Windows Active Directory and cloud IAM. Linux identity lives in /etc/passwd, sudoers files, PAM modules, and authorized_keys -- a completely different plane that generic tools cannot see.

  • Privileged access management tools focus on session recording, not Linux-native privilege mapping
  • Vulnerability scanners find CVEs but miss dangerous sudo configurations and privilege escalation paths
  • Cloud security posture tools audit IAM policies but ignore the OS-level identity layer underneath
  • LinuxGuard is purpose-built for the Linux identity plane -- sudo, PAM, SSH, users, groups, and service accounts

Compliance Framework Alignment

Our methodology aligns with industry-recognized security frameworks to ensure your identity infrastructure meets regulatory requirements.

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.
