A human-sized and independent company

Created in 2008 by a cybersecurity engineer (still working today). AlgoSecure is an IT security company based in Lyon and specialised in information systems security.

Eager to develop around a controlled organic growth, our company has the will to remain at human size : the integration of each person, the interactions and our culture are particularly important to us.

We ensure that we are truly independent of editors and constructors. We do not belong to any group of companies and are not dependent on any partnership. This allows us to offer you objective support and advice, particularly in the area of staff delegation.

Located in the heart of Lyon Part-Dieu, we have offices in Paris, Lille, Grenoble, Toulouse, Strasbourg and Marseille.


Our structure allows us to gain agility, proximity to better meet our clients' needs.
