A Session Border Controller (SBC) is a critical security and traffic management tool for VoIP networks. It sits at the edge of your communication system, monitoring and managing voice sessions to ensure secure and reliable connections. From protecting against SIP-based threats like DoS attacks and toll fraud to ensuring seamless interoperability between different VoIP platforms, an SBC plays a key role in optimizing performance and safeguarding communication infrastructure. Whether for enterprises or service providers, deploying an SBC is essential for maintaining VoIP call quality, security, and regulatory compliance.
