They invent tomorrow’s cyber security


HAVEall risky people

Elena Poincet and Laurent Oudot

Do you have to go through the Directorate-General for External Security to fight cybercrime? This is the case with Éléna Poincet (Photo), formerly of the Action department, which in 2010 created the startup Tehtris with Laurent Oudot. Educated at the Technical University of Munich, l’X and Berkeley, he also went through the intelligence services. “Our job is a struggle and we must not give up”, explains Éléna Poincet. Tehtris has developed a platform that wants to neutralize attacks in real time, already used by the Ministry of the Armed Forces and Paris airports. tehtris.com

Protected messages

Thomas Baignères and Matthieu Finiasz

Do you know Olvid? This message, which means “forgotten” in Spanish, was created by Thomas Baignères (Photo), 43 years; it has already attracted 80,000 users. “Every individual, every business must retain full ownership of their data. Expressing themselves in a peaceful manner is for me a fundamental right”, explains this holder of a thesis in cryptography from the Federal Polytechnic School of Lausanne, who got the idea for Olvid with the normal Matthieu Finiasz, holder of a thesis at Inria. Their app has received top-level certification from the National Information Systems Security Agency, which protects critical state infrastructure. This is not the case with WhatsApp, Signal or Telegram. olvid.io

Handling quantum threats

Jean-Charles Faugere and Ludovic Perret

From academic research Jean-Charles Faugère, research director at Inria, and Ludovic Perret (Photo), a teacher-researcher at the Sorbonne, founded a start-up called CryptoNext Security in 2019. Its mission: to address the emergence of quantum threats in cybersecurity. Its weapon: software that combines current cryptography standards and new standards to resist the quantum computer and ward off attacks for decades! cryptonext-security.com

Against the black screen

“It is not normal to have software errors”, Stormen Fabrice Derepas (photo, left). With two former colleagues from the Atomic Energy Commission (CEA-List), Benjamin Monate (photo, right) and Pascal Cuoq, he founded TrustinSoft in 2013. The challenge for these three computer scientists was monumental: creating software to correct computer code and enabling developers to mathematically ensure that there are no errors. trust-in-soft.com

Cross data

Gregoire Germain and Xavier Boreau

From their time in the French navy, the two former officers Grégoire Germain (Photo) and Xavier Boreau claim to have retained the team spirit, transferred to their company HarfangLab. To detect suspicious activity, they not only have a block list as antivirus, but they monitor the behavior of connected devices by analyzing as much data as possible. harfanglab.io

Democratize the use of secure data

Sandrine Murcia, Bruno Grieder, Raphaël Auphan and David Pointcheval

Central Raphaël Auphan founded the sleep specialist firm Zyken, sold to Withings; computer science doctor Bruno Grieder (Photo) founded document exchange specialist Amalto Technologies, while Insa-trained engineer Sandrine Murcia spearheaded European marketing for Google. With Cosmian, they have combined their skills to create a software publisher that allows groups or government institutions to leave their most sensitive data to third parties who can manipulate them without any of the parties being able to reclaim the company’s property. . . The trio is advised by David Pointcheval, CNRS silver winner. cosmian.com
