Who Are We?
What we do
We discover and prevent financial fraud based on forged documents, manipulated transactions and stolen or synthetic identities.
Our first company, Cognitive Security, was sold to Cisco in 2013. It provided the foundation for what is now Cisco’s Cognitive Threat Analytics (CTA) platform which protects some 25 million users in Fortune 1000 companies.
