OWN-CERT is an inter-company Computer Emergency Response Team (CERT) service created in 2013, initially serving French OIVs (Operators of Vital Importance), CAC40, and SBF120 organizations. In 2021, OWN expanded the service via a subscription model to make it accessible to companies of all sizes, including VSEs, SMEs, and ETIs. The service is structured around two core areas of expertise: **CTI (Cyber Threat Intelligence):** Analysts track and analyze adversary tactics, motivations, malware, and attack infrastructures. Activities include identifying and analyzing online criminal activities, producing sector-specific or customized threat panoramas, distributing contextualized security newsletters, and transforming technical and non-technical (geopolitical, economic, business) information into actionable intelligence. **DFIR (Digital Forensics and Incident Response):** Analysts provide on-demand or on-site support for detecting security events on customer information systems, managing security incidents, performing digital forensics, analyzing malicious code, and issuing recommendations and public newsletters on observed vulnerabilities and TTPs. The team consists of 28 analysts covering Incident Detection & Response, Cybercrime and Investigations, and Advanced Threats. Analysts are multilingual (Russian, Chinese, Arabic, Korean, Ukrainian, Romanian, German, Spanish, English) and include cybersecurity engineers, incident response analysts, geopolitical analysts, cybercrime analysts, lawyers, malware analysts, DevOps, SOC analysts, forensic experts, and data analysts. The team produced 400+ reports/year in 2023.
