How it works
Callsign products use deep learning techniques to combine event, threat, and behavioural analytics with multi-factor authentication, securing access to services whilst uniquely ensuring the most frictionless and transparent user experience.
What problem does the company solve
Organisations and their customers demand the utmost in security without any UX compromises. Callsign gives legitimate users just that, offering seamless and secure experiences, whilst keeping the bad actors firmly locked out. Our world-leading solutions help organisations prevent fraud including online scams, account takeover, and threats (e.g. malware and bots).
