Cryptosense was founded in 2013 by Graham Steel PhD. He saw a market need for tools that would help people use cryptography in a secure way.

After 15 years as a researcher in Formal Methods and Verification, Graham saw that although it is embedded throughout every company’s applications and infrastructure, cryptography is difficult to deploy effectively. It is often implemented incorrectly and problems are hard to identify by manual checks.

Graham also saw that cryptography failures have a huge impact: catastrophic loss of data, reputational damage and financial loss. In major organizations, fear of cryptography failure blocks necessary digital transformation and migration to public cloud.

Cryptosense was founded to provide a reliable automated solution to this problem. Our product CAP is now used by major financial institutions worldwide.

The company is built on close collaboration with our partners in academia, in particular Dr. Ricardo Foccardi at the University Ca’ Foscari in Venice. Clément Jeanjean joined the management team, after many years experience of running successful startups. We’re also fortunate to have a great group of software developers from all over the world, bringing their enthusiasm and expertise to solve the difficult problem of automating cryptography management.
