Network & Security Services

Security is no longer a perimeter firewall and a password policy. Ransomware, supply-chain attacks, and AI-era data exfiltration target every size of organization, and the answer is layered, inspectable, open-source security you actually control. eRacks designs, deploys, and hardens that infrastructure, backed by our affiliated security company, Security Architects Inc.

What we do:

• Zero-trust network design: segment and verify everything (zero trust means no device or user is trusted by default), from flat legacy networks to segmented, least-privilege architectures.
• Open-source firewalls and VPN: OPNsense and pfSense firewalls, WireGuard VPN (the modern, fast, auditable tunnel), nftables policies, no black-box appliances and no per-seat license treadmill.
• Detection and monitoring: Suricata and Zeek intrusion detection (IDS, watching traffic for attack patterns), Wazuh security monitoring and log analysis (open-source SIEM), with alerts your team can actually act on.
• Hardening and patch discipline: servers and desktops hardened to CIS benchmarks (the industry-standard secure-configuration baselines), automated patching, MFA and single sign-on with open-source Keycloak.
• Ransomware resilience: immutable and offline backups, tested restores, and a recovery plan written down before you need it.
• Air-gapped and egress-controlled networks: for regulated data and private AI, we build networks where nothing leaves the building - the same discipline behind our AI Provisioning air-gap deployments.

Deliverables include:

• A written security review: findings ranked by risk, each with a concrete remediation
• Deployed and configured open-source security infrastructure (firewalls, VPN, IDS, monitoring)
• Hardened system baselines with the settings documented
• A ransomware recovery plan with tested restores
• A live handoff session with your team, plus 30 days of follow-up email questions

Part of the eRacks services family: start with an Open Source Assessment, move platforms with Linux Migration, build with AI Agentic Engineering & Software Development, and deploy private AI with AI Provisioning & Setup. For deeper security engagements and security products, see Security Architects Inc products and services.

Every engagement starts with a half-day scoping session (default below), credited toward the project if you proceed. Prefer to start smaller? Choose the one-hour discovery call. Larger environments step up to full-day, one-week, or one-month engagements, and bigger programs are quoted to your scope.
