A firewall is a security tool that helps protect computers and networks by monitoring and controlling incoming and outgoing traffic based on a defined set of security rules. It is one of the oldest, and still one of the most important, layers of network defense.
Filtering Traffic
At its core, a firewall inspects traffic passing in and out of your network and blocks anything that does not match approved rules — stopping unauthorised access before it reaches your systems.
Segmenting Your Network
Modern firewalls can also segment a network into zones, so that a breach in one part of the business does not automatically expose everything else.
Supporting Remote Work
Firewalls with built-in VPN capability let staff connect securely from anywhere, extending your protected network to wherever your team is working.
Why It Is Not Enough on Its Own
A firewall is essential, but it is one layer among many. Endpoint protection, staff training and monitoring all work alongside it to form a complete security posture.
