Networks & Firewalls

We design and implement secure business network infrastructure, using pfSense and OPNsense as enterprise-grade open source firewall solutions. We build segregated zone architectures, site-to-site and client VPNs, traffic management and monitoring systems.

We conduct security audits of existing networks and propose hardening plans. We support SD-WAN transitions, VLAN implementation for separate OT/IT environments, and regulatory compliance (NIS2, GDPR).
