Network Security

Firewalls are vital network security tools that regulate incoming and outgoing traffic based on predefined rules, creating a barrier between trusted internal networks and untrusted external sources like the internet. Next-generation firewalls (NGFWs) add application layer filtering for nuanced traffic control, often integrating with cloud services. They include intrusion detection and prevention systems (IDPS) to identify and respond to potential threats. Firewalls also support Virtual Private Network (VPN) technologies for secure internet communication, crucial for remote access. As a cybersecurity cornerstone, firewalls protect network resources and data by serving as the initial defense against unauthorized access and cyber threats.
