Hardening the baseline
Secure configuration across the fleet, aligned to CIS where it applies
persona - Security Lead
The engineers who implement your controls
You decide what the posture has to be. We do the Linux work that gets you there: hardening configurations, closing the findings your scanner and your auditor raised, getting unsupported distributions off the estate, and documenting what changed. We are not your detection service. We are the engineering capacity behind your security program.
Findings into fixes
Remediating what your scanner, auditor or pen test surfaced
Unsupported systems
Getting end-of-life distributions off the estate
Evidence for the audit
Documented controls, configuration changes and remediation work
Common challenges
What lands on your desk
The Linux exposures and findings we are usually asked to close.
Security Hardening
SSH policy inconsistencies, outdated packages, audit findings on privileged access, and configuration drift across production fleets.

Compliance & Auditing
Infrastructure aligned with regulated audits, agency security and privacy programs, commercial frameworks where public services touch the private sector, and internal controls that need proof, not narrative alone.
Learn more >
Data Sovereignty
Cross-border cloud footprints, residency requirements, and classification boundaries, where workloads live, who can access them, and how you prove both to auditors and oversight bodies.

Legacy Modernization
Modernizing aging Linux systems without disrupting transaction-processing windows or core banking schedules.
Learn more >
Disaster Recovery
Tested failover, backup integrity, and recovery objectives that hold up under examiner scrutiny.

Regulated Infrastructure
Infrastructure designed to the operational and security standards regulated industries actually need, not just technically capable, but appropriate.

Policy PDFs are not a control plane. You need security you can trust when it is actually tested.
Operational philosophy
How We Help
What we actually deliver
Implementation and evidence, not another assessment.
Reduced Attack Surface
Secure configuration applied across the fleet: SSH, privileged access, permissions, authentication, and only the services you need running.
Findings Actually Closed
Engineering capacity to remediate what your scanner and your auditors raised, rather than another report explaining why it is still open.
Supported Operating Systems
End-of-life distributions upgraded or migrated, so you stop carrying exposure nobody is shipping patches for.
Standards That Hold
Configuration standardized across servers and kept that way, so a hardened baseline does not quietly drift back over a year.
Controls You Can Evidence
Technical controls implemented and documented, with the change record an auditor expects to be shown.
Engineering, Not Another Opinion
We implement what your security program has already decided. We are not a detection service and we do not replace your SOC.
Featured success
Proof, not promises
Real engagements, real outcomes.
