How does firewall hardware work?

Firewall hardware inspects incoming traffic and allows or blocks data packets based on pre-configured security policies, user profiles, and business rules. All data moving across networks comprises packets containing header information, communicating the packet's source, type, and destination.

Advanced firewall hardware solutions can go further by enforcing progressive security policies to detect potential malware, zero-day threats, brute force attacks, unauthorized access, and various other security risks.
