CAPSO

CAPSO, also known as CAPSO digital service, is an organisation based in France that delivers digital services to its clients. The organisation’s involvement in the ransomware attack on the municipality of Saint‑Martin‑lez‑Tatinghem on 21 June 2023 demonstrates its role in responding to cybersecurity incidents. During that event CAPSO took immediate containment actions such as isolating affected machines and disconnecting internet access. CAPSO collaborated with cybersecurity and law‑enforcement agencies to investigate the breach and restore secure access to preserved data. The organisation also helped issue public advisories about possible fraudulent use of compromised information.

CAPSO’s headquarters are located in France. The organisation’s digital service offering is reflected in its alias and the nature of its response to the cyber incident. While the exact size, revenue, or client base of the organisation is not disclosed in the available sources, its role in the 2023 ransomware response demonstrates a specialised capability in incident containment and coordination with authorities. No information about parent companies, subsidiaries, or ownership structure is provided in the material. Consequently, the profile focuses on the confirmed facts regarding the organisation’s service focus, geographic base, and demonstrated incident‑response activity.
