Firewalls are security measures designed to monitor and control incoming and outgoing network traffic to and from a server. Acting as a barrier between the server and potential threats, firewalls analyse data packets to determine whether they should be allowed or blocked based on predefined security rules.
Firewalls help prevent unauthorised access, protect against malicious attacks, and improve the overall security of a web hosting environment.
