Applying hardware-enforced cryptographic filters to legacy SS7 MAP and Diameter signaling messages.
SS7 signaling was designed in an era of state-owned telecommunications monopolies where all connected parties were trusted. Today, rogue actors purchase access to global SS7 hubs to track target smartphones globally and intercept SMS 2FA codes. TeleHSM inspects incoming SS7 and Diameter traffic, verifying cryptographic partner signatures before allowing routing queries.
TeleHSM enforces SMS Home Routing: incoming mobile-terminated SMS messages are redirected to the home operator's secure gateway, which verifies recipient identity and decrypts message bodies inside hardware enclaves, neutralizing interception on transit links.
