WatchGuard Firebox M5850
High-performance firewall with 58 Gbps firewall throughput and unlimited VPN tunnels

Overview:

Consistent Security Performance for High Traffic Environments

The Firebox M5850 is purpose-built for organizations running larger sites, campus networks, and distributed enterprise environments where encrypted traffic and application density constantly pressure the firewall. Positioned at the core of the Firebox High Rackmount family, the M5850 delivers higher sustained security throughput and session capacity than entry-level high rackmount models, enabling consistent protection even during peak usage. With native high speed interfaces and redundant hardware standards, it provides a stable foundation for growing networks without forcing architectural compromises.

Specifications:

¹ Throughput rates are determined using multiple flows through multiple ports and will vary depending on the environment and configuration. Max firewall throughput tested via direct connection using 1518-byte UDP frames based on RFC 2544 methodology. All testing performed on Fireware version 2025.1.
² UTM throughput is measured using HTTP traffic with AV, IPS, and Application Control enabled, and does not account for all security services available on the appliance.
