Firewall Technologies
overall review score: 4.3
⭐⭐⭐⭐⭐
score is between 0 and 5
Firewall technologies are security systems designed to monitor, filter, and control incoming and outgoing network traffic based on predefined security rules. They serve as a barrier between trusted internal networks and untrusted external networks, such as the internet, to prevent unauthorized access and cyber threats. Firewalls can be hardware-based, software-based, or a combination of both, and they are essential components of modern cybersecurity strategies.
