Frequently asked questions
Which firewall platforms does NetworkOverIT support?
pfSense, OPNsense, Cisco ASA/FTD, WatchGuard, MikroTik and Huawei. We design multi-site firewall architectures with HA pairs, VLAN segmentation, VPN tunnels (OpenVPN, IPsec, WireGuard) and IDS/IPS.
What is a firewall migration?
A firewall migration replaces an existing firewall with a new one without service interruption. NetworkOverIT has migrated pfSense to Cisco Secure Firewall in multi-site environments with zero-downtime cutover.
How long does a firewall migration take?
It depends on complexity. A single site takes 1-2 weeks (design, implementation, testing). A multi-site deployment with 5+ sites in HA configuration takes 2-3 months.
