OWN Réponse Incident is a professional incident response service offered by OWN, a French cybersecurity company holding ANSSI security visa certification and CERT qualifications (TF-CSIRT, Inter CERT France). The service is available in two engagement models: on-demand and subscription-based. Core service areas include: **Levée de doutes (Doubt Clearance):** Threat assessment tailored to the client's sector, geographic presence, partners, and supply chain. Includes identification of threat actors likely to target the organization and in-depth analysis of their tactics, techniques, and procedures (TTPs). **Live Forensics:** Real-time and post-mortem forensic examination of systems following an incident. Includes an exposure inventory covering the information system, organization, and associated individuals, as well as detection of leaks, operational security flaws, exposed assets, and dark web access sales. **Malware Analysis:** In-depth investigation of malicious software, with risk management associating each finding to a hypothesis, probability of occurrence, and impact evaluation. **Threat Hunting:** Proactive examination of infrastructure to identify current and historical threats. Includes analysis of apparently healthy infrastructure and exhaustive exploration of the threat spectrum using a critical, proactive methodology.
