About Symbolic Software.
Symbolic Software is an applied cryptography consultancy founded in 2017 by Dr. Nadim Kobeissi in Paris. Our thesis is simple: AI systems can now discover and exploit implementation bugs at scale, which means security has to start at the design level—the protocol architecture, the cryptographic choices, the threat model.
That is the work we have been doing since the beginning. Over 250 security engagements for organizations including 1Password, Mozilla, Zoom, Coinbase, and the Linux Foundation. Peer-reviewed research software used by cryptographers and engineers worldwide. A university course training the next generation of design-level security experts.
We also make puzzle games for Nintendo Switch and Steam.
