The firewalls that once protected businesses are no longer adequate against today's cyber threats. With AI-driven attacks and encrypted malware on the rise, organizations need more advanced visibility and control across their networks.
Next-generation firewalls (NGFWs) address this gap by inspecting traffic at a deeper level, analyzing the actual data within packets to detect and block modern threats. They combine capabilities intrusion detection and prevention, SSL traffic inspection, and application-aware controls into a single platform, creating a critical layer of modern cybersecurity.
