The M4800 is designed for large enterprises that deploy the firewall as a central data center hub in a hub-and-spoke topology. With 5,000 Branch Office VPN tunnels, two expansion module slots, and 49.6 Gbps firewall throughput, it serves as the security backbone for organizations with extensive distributed networks.

The M4800 has two open expansion module slots. Each slot accepts one of four module types: 4x10G fiber, 8x1G copper, 8x1G fiber, or 2x40G fiber. You can mix module types across the two slots to create a port configuration that matches your specific connectivity requirements.

Yes. The M4800 ships with dual 300W hot-swap power supplies as standard equipment. Both power supplies are active simultaneously, and either can be removed and replaced while the appliance continues to operate, which is critical for data center environments where downtime is unacceptable.

The M4800 supports 5,000 Branch Office VPN tunnels and 10,000 Mobile VPN sessions. This capacity makes it appropriate for large enterprises with dozens or hundreds of remote sites connecting back to a central hub location.

The M5800 delivers significantly more throughput than the M4800: 87 Gbps versus 49.6 Gbps firewall throughput, 11.3 Gbps versus 5.2 Gbps UTM throughput, and 30,800,000 versus 15,000,000 concurrent connections. The M5800 also supports unlimited Branch Office and Mobile VPN tunnels compared to 5,000 and 10,000 on the M4800, and its base spec includes 4x10G SFP+ ports alongside 8x1G.
