Networks & security

The network is the backbone of the whole company. We build it to be fast, separated where it should be, and protected against attacks from outside and inside.

What we deliver

  • firewalls and routers (OPNsense and others) including multiple internet links and failover
  • site-to-site and remote-access VPN (WireGuard, IPsec)
  • network segmentation (VLAN) — separating guests, cameras, servers and office
  • reverse proxy and TLS certificate management (Let’s Encrypt)
  • Wi-Fi for offices and guests
  • email protection — SPF, DKIM, DMARC, filtering and geo-blocking
  • security audits and recommendations

Why do it properly

Most incidents do not start with a sophisticated attack but with an open port, old firmware or a shared password. Regular reviews and a well-configured network are the cheapest protection.

Where AI helps

  • analysis of firewall logs and security events
  • plain-language explanation of suspicious traffic and suggested actions
