Why these models matter

2.5x faster throughput for packet inspection and traffic handling in high-traffic environments, with multi-gigabit WAN/LAN ports up to 2.5G Ethernet.

AI-powered intrusion prevention, integrated VPN and unified threat management covering antivirus, content filtering and application control in a single device.

Built for SMBs and MSPs

Flexible deployment, scalable licensing and full remote management make these appliances a natural fit for service providers managing multiple client sites.

Existing Kerio customers migrating from the NG510/NG511 will find the transition straightforward and immediately beneficial.

What's coming next

GFI has announced three further models in the same next-generation family: the compact NG120 for branch offices, the mid-range NG320, and the NG720 for high-availability enterprise deployments.

All are available to order through FUSE with immediate availability, EU delivery options and partner discounts.
