Network & Security

Network infrastructure and security are areas where transparency is more than a nice-to-have; it is a necessity. When your firewall rules, VPN configurations, and DNS resolution depend on proprietary appliances and closed software, you are trusting a vendor’s assurances instead of verifying the behaviour yourself. Open-source networking tools give you full visibility into how your network operates and how it is protected.

We advise on the design and architecture of open-source network infrastructure: WireGuard for fast, modern VPN connectivity; nftables or PF for firewall management; BIND or Unbound for DNS; and open routing solutions for more complex topologies. These tools are widely deployed, actively maintained, and trusted in environments where security is non-negotiable.

Network design decisions have long-lasting consequences. How you segment your network, where you place your firewalls, how you handle DNS resolution, and how remote access is structured: these choices define your security posture for years. We help you think through these decisions with an emphasis on simplicity and auditability. Overly complex network architectures tend to develop blind spots, and blind spots are where security incidents start.

We also address the operational aspects: how firewall rules are documented and reviewed, how VPN access is provisioned and revoked, how DNS changes are tracked, and how the overall network posture is monitored. The result is a network architecture that your team can understand, maintain, and defend without relying on a vendor’s black box.
