-Zdeněk knew the company’s VPN setup had to evolve. The team had experimented with WireGuard in the past, but out of the box, it lacked key features like true MFA enforcement and centralized user management. Prusa already utilises FortiGate router which can be at additional cost extended to handle MFA (with ef. FortiToken) for VPN, but the support is limited to IPsec and SSL VPN protocols (soon to be discontinued) which lack robustness and speed that WireGuard delivers.

 Zdeněk ruled out most SaaS VPNs like Tailscale, Firezone or Netbird platforms early in the process. While Firezone is in theory self-hosted, in practice they don't offer documentation or support.
