Firewall

A firewall is an essential network security device that monitors and filters incoming and outgoing traffic, based on a set of predefined security rules.

It acts as a barrier between a secure internal network and another unsecured network, such as the Internet. It helps decide whether or not specific traffic can pass through, protecting systems and data from online threats.

A firewall secures your information system via :

• Access control or websites/applications/protocols, such as social networks, adult content, illegal content or video platforms that reduce your bandwidth
• Internal/external traffic monitoring
• Implementing safety rules
• Restricted access

It will also enable you to apply Quality of Service (QOS) rules, guaranteeing a minimum throughput for critical applications by allocating them a guaranteed, reserved percentage of your throughput.

By filtering unauthorized traffic and preventing intrusions, the firewall is the first line of defense. It is an indispensable security element in today's digital world.
