Turn Linux fleet drift into an actionable remediation roadmap

For platform leads and IT operations accountable for uptime, managing a production Linux fleet is a battle against configuration drift. You need to know not just that a system is failing, but exactly why, how to fix it, and how to prove it is healthy again. This SRE audit provides that technical baseline.

Evidence-backed reliability for strategic planning

This audit is designed for organizations in the strategic planning phase—those managing their own budgets to build resilience or meet regulatory requirements. It is a defined-scope project that delivers a single, browsable report: a one-page executive verdict followed by a severity-ranked risk register.

Unlike generic scanners that bury you in noise, our findings are anchored to your own system. Every claim in the report is backed by verbatim lines of output from your host. This ensures that when the report says a service is failing or a configuration is insecure, your engineers can verify it instantly.

Compliance evidence for NIS2 and the CRA

While this audit is not a formal certification, it provides the technical evidence required to demonstrate compliance with major EU frameworks.

NIS2: Under Directive (EU) 2022/2555, the audit supports Article 21(2) risk-management measures by identifying active anomalies (failed services, OOM kills, abnormal log patterns) and assessing basic cyber hygiene (firewall rules, SSH hardening, and patch status).
Cyber Resilience Act (CRA): Under Regulation (EU) 2024/2847, for manufacturers of products with digital elements, the audit provides evidence toward Annex I requirements by identifying insecure defaults and ensuring security updates are available and applied to the underlying host infrastructure.
EU AI Act: Under Regulation (EU) 2024/1689, the audit assists in maintaining the integrity of the infrastructure hosting AI models by monitoring system stability and resource limits.

By using a fixed catalogue of checks across more than a dozen subsystems, we ensure that your compliance posture is measured consistently over time.

A non-intrusive, read-only process

We understand that production stability is the priority. The audit is a state-collecting, read-only engagement that changes no configuration, no service, and no data.

We use standard diagnostic tools—such as systemctl, ss, journalctl, iostat, and smartctl—to collect the current state of your system. The only write operation performed is the creation of a transient temporary file for disk-speed probing, which is deleted immediately. The audit runs unprivileged under your control, ensuring it clears even the strictest change-advisory boards.

Each subsystem is audited thoroughly, including:

System services and processes: Identifying failed units and resource hogs.
Authentication and access: Checking SSH, PAM, and sudo configurations.
Network and Firewall: Verifying listening ports and nftables/iptables rulesets.
TLS and Certificates: Checking for certificate expiry across web, mail, and proxy paths.
Storage and Kernel: Monitoring disk health, SMART status, and kernel error logs.

Note that while we check certificate expiry, we do not manage your PKI infrastructure. We recommend a quarterly re-audit cadence to catch the drift that occurs between snapshots.

Stop triaging noise and start fixing what matters. We provide the commands to apply a fix, the commands to verify it, and the path to roll it back if it fails.
