SBCs and WAFs exposed as security cousins: because exposing anything to the internet means stacking firewalls like a paranoid founder's wet dream, cue SafeLine

A recent analysis highlights the importance of Session Border Controllers (SBCs) and Web Application Firewalls (WAFs) in protecting real-time communications and web applications from security threats. SBCs, commonly used in VoIP and SIP networks, enforce protocol rules, track sessions, and prevent abuse, while WAFs defend HTTP-based applications and APIs from attacks such as SQL injection and cross-site scripting. Although they operate in different domains, both technologies share a similar design philosophy, aiming to understand protocol intent and normalize behavior at the boundary. The integration of SBCs and WAFs, such as SafeLine WAF, provides a more resilient architecture, reducing the attack surface and protecting critical systems. As real-time communication platforms increasingly expose web interfaces, the web layer becomes a primary attack vector, making WAFs essential. By combining SBCs and WAFs, organizations can ensure comprehensive security, protecting both real-time communication and web layers from evolving threats.
