Network security devices are hardware or virtual appliances designed to protect computer networks from unauthorized access, data breaches, and cyberattacks. They include firewalls, intrusion prevention systems, VPN gateways, and other tools that safeguard data across network connections. These devices act as barriers between the internal network and potential threats from the outside world.
