Fortinet FortiGate FG-91G Network Security/Firewall Appliance

The Fortinet FG-91G is a network security and SD-WAN appliance that gives growing businesses a single point of control for protection, performance, and connectivity. It works as a next-generation firewall that inspects traffic in real time, blocks malware before it reaches users, and enforces zero-trust policies across every connection.

Inside, the FortiASIC SP5 processor accelerates deep inspection so security does not slow the network. Ten built-in ports support speeds up to 10 Gb, letting you segment voice, data, and guest traffic without adding extra switches. A 120 GB solid-state drive stores logs locally and helps the system act on security events without delay.

Remote and hybrid teams stay protected through the appliance’s integrated VPN, which supports up to 2 500 concurrent connections. Whether staff are working from a branch office, a home office, or while travelling, their sessions remain encrypted with standards such as SHA-256 and TLS 1.3.

Deployment is straightforward. The compact chassis rests neatly on a desk or shelf, and an optional redundant power supply adds resilience for sites that cannot afford downtime. Centralised management through FortiGate Cloud or on-premises tools makes it easy for IT teams to push policies, monitor bandwidth, and run reports across multiple locations.

Each unit includes one year of FortiCare Premium support, giving administrators direct access to firmware updates and expert assistance whenever questions arise.
