Boost Your Business with EIS's IT Services

 A firewall in a computer network provides security at the perimeter by monitoring incoming and outgoing data packets in network traffic for malware and anomalies. A firewall filters traffic as it attempts to enter and exit your network as opposed to antivirus software that scans devices and storage systems on the network for threats that have penetrated your defenses. 

A firewall is designed to follow a predefined set of security rules to determine what to allow on your network and what to block.

Depending on where it is deployed and its purpose, a firewall can be delivered as a hardware appliance, as software, or software as a service (SaaS). There are five main types of firewalls depending upon their operational method:

1. stateless or packet filtering firewall
2. stateful inspection firewall
3. circuit-level gateway
4. application-level gateway
5. next-generation firewall (NGFW)

Fortinet FortiGate NGFWs combine the protection of the five types of firewalls with the advanced security capabilities . They can be deployed as software or hardware and can scale to any location: remote office, branch, campus, data center, and cloud.

FortiGates are the only NGFWs with unified management for hybrid mesh firewalls and consistent security across complex, hybrid environments.
