5G slice security: production-ready

The challenge

A tier-1 telco faced two distinct telco-specific security challenges: SS7 fraud (legacy signalling) and 5G network-slice isolation (new architecture). Both required protocol-layer security expertise.

What we built

SS7 firewalling with anomaly detection. 5G slice security including isolation enforcement + threat detection at the slice layer. Telco-specific SOC playbooks. Integration with industry threat intelligence (3GPP, GSMA).
