What Devensys Cybersecurity does

Devensys Cybersecurity is a France-based pure-play cybersecurity services firm founded in 2013 in Montpellier, operating through offices in Lyon, the Paris area (Suresnes), Martinique (Fort-de-France), and New Caledonia (Nouméa). The company is structured as a SASU with Léo Gonzalez and Alexandre Marguerite listed as co-founders, and it markets itself as 100% French-owned and operated with all experts and SOC/CERT teams located in France.

Its service portfolio is organized around three operational pillars: offensive security (Red Team and Pentest, including physical intrusion and social engineering), defensive security (24/7 SOC with a guaranteed intervention time under 30 minutes, plus Managed Cybersecurity Services), and incident/vulnerability operations (CERT/CSIRT response with GTI 2h, and a Vulnerability Operations Center covering scanning, External Attack Surface Management, predictive protection, and open/dark-web monitoring). Adjacent offerings include Identity Management/SSO implementation and system-and-network infrastructure services. The Training & Certification Center, Qualiopi-certified, delivers programs through official partnerships with EC-Council (CEH, CCT), OffSec as a Gold Partner (OSCP), ISC2 (CISSP), and HackTheBox.

Commercially, Devensys sells through direct enterprise field sales, with revenue drawn from project-based security engagements, recurring SOC and CERT retainers, and training/certification sales (per-seat course pricing and annual HackTheBox subscription resale). Named clients on the company site include the Ministère des Armées, OTAN (NATO), Septeo, and Alain A, spanning government, defense, enterprise software, and professional services verticals. The firm does not disclose revenue, has not raised external funding rounds, and lists €2,877,919 in share capital as its principal balance-sheet datapoint.
