Firewalls are like the security guards of a network—they monitor and control incoming and outgoing traffic based on predefined security rules. Their main job is to protect your network from unauthorized access, cyberattacks, and data breaches.

VPN stands for Virtual Private Network. It is a technology that allows users to create a secure and encrypted connection over a less secure network, typically the internet. VPNs are commonly used to protect sensitive data, maintain online privacy, and access content that may be restricted based on geographic location
