We are all R&D researchers who specialize in areas such as vulnerability research, exploit development, engineering or cryptography.

We offer tailor-made training classes for our customers : iOS, android, browsers, cryptography and more.

We like to be involved with the community and contribute to security events.
In 2025, we’re already sponsoring Hexacon, OffensiveCon, Pass-The-Salt, STHack, BreizhCTF, THCon and DistrictCon.

At Epsilon, we like hard problems and can help our customers with difficult low-level tasks. We have expertise in security, low-level engineering and cryptography.

Because we believe in helping youth.
We also started with CTF and wargames!
