What is Cisco Firewall?

Cisco Firewalls are network security devices that monitor and control incoming and outgoing network traffic based on pre-defined security rules. They are commonly used to protect networks from unauthorized access, malware, and other cyber threats by creating a barrier between trusted internal networks and untrusted external networks like the internet. Cisco offers a range of firewalls, including hardware and software-based solutions, suitable for small businesses to large enterprises.
