SIM swap & call divert

Telecoms data is a valuable tool in preventing social engineering and Account Takeover, adding an additional layer of identity verification to Callsign's watertight solution.

Real-time protection

With Callsign's Telco intelligence, the chips are down for fraudsters. We secure your SMS OTPs and protect against Account Takeover (ATO) with real-time SIM swap timestamps that ensure you're not getting caught out.

Prevent
SS7 attacks

Once a fraudster has a customer’s credentials and has attempted to login to their target’s account, SMS or outbound calling authentication should, in theory, stop them in their tracks. However, fraudsters have found a way to intercept these messages with SS7 being the gateway. Callsign's use of telecoms intelligence can help to prevent these risks.
