Our High-Performing Core Network
Fully virtualizable on VMware, K8S, Docker and OpenStack containers
Security Edge Protection Proxy(SEPP)
SEPP (Security Edge Protection Proxy) is a key element in 5G core networks, enabling secure and trusted communication across operator boundaries. It plays a vital role in supporting 5G roaming and inter-PLMN interoperability by safeguarding control-plane signaling between networks.
Positioned at the edge of the operator’s core network, SEPP filters, mediates, and protects signaling messages exchanged with partner operators. Through the standardized N32 interface, SEPP applies encryption, integrity protection, and policy enforcement to ensure signaling confidentiality and trust.
