Network Security Tools FAQ
Common questions about Network Security tools, selection guides, pricing, and comparisons.
Traditional firewalls filter traffic based on ports, protocols, and IP addresses. Next-generation firewalls (NGFWs) add application awareness (identifying apps regardless of port), integrated intrusion prevention (IPS), SSL/TLS inspection, user identity awareness, and threat intelligence feeds. NGFWs can block specific application features while allowing the app itself.
NDR (Network Detection and Response) uses machine learning and behavioral analysis to detect threats in network traffic, including encrypted traffic analysis. Traditional IDS (Intrusion Detection Systems) rely primarily on signature matching against known attack patterns. NDR catches novel attacks and lateral movement that signature-based IDS would miss, and adds automated response capabilities.
Yes. Zero trust reduces reliance on network perimeter security, but network security tools remain essential for: detecting lateral movement, monitoring east-west traffic, protecting legacy systems that cannot support zero trust agents, DDoS mitigation, and providing visibility into encrypted traffic. Zero trust and network security are complementary, not replacements for each other.
