Infrastructure Hardening

Independent hardening and auditing of the systems that run your business: Cisco and Dell switching and routing, and Windows and RHEL servers, measured against the baselines auditors recognize.

Cisco and Dell switching and routing infrastructure and cabling

Cisco and Dell switching and routing

Switch and router hardening and configuration review across the network.

  • Switching and routing. Configuration hardening for Cisco and Dell switches and routers against the baseline.
  • Segmentation. VLAN, VRF, and access-control review to contain lateral movement.
  • Management plane. AAA, secure protocols, logging, and out-of-band access done right.
  • Remediation plan. Prioritized, low-risk changes sequenced for a change window.
No. 02 · Servers
Reviewing Windows Server and Red Hat Enterprise Linux security configuration

Windows and RHEL server hardening

Server operating-system hardening and audit across the estate.

  • Windows Server. Group Policy, accounts, services, and patch posture hardened to baseline.
  • Red Hat Enterprise Linux. Accounts, SSH, SELinux, auditd, and services hardened and audited.
  • Scan and verify. Microsoft and OpenSCAP-based assessment with findings mapped to fixes.
  • Repeatable. Hardening captured as automation so it holds across rebuilds.
No. 03 · Baselines

Measured against what auditors recognize.

  • CIS Benchmarks v8. The recognized hardening baseline, gap to green.
  • DISA STIGs. Defense-grade hardening where the contract requires it.
  • NIST SP 800-53. Control mapping for regulated environments.
  • Independent review. A second set of eyes, not the team that built it.
  • Source-file deliverables. Findings, configs, and runbooks you own.
  • Automation-ready. Hardening that can be enforced continuously.
