mabris.fr) zoominfo.com/c/mabris/513443412MABRIS is a French family-owned industrial contractor based in Saint-Pierre-la-Cour (Mayenne), founded in the 1980s and registered as an SAS in 1999, with a second workshop in Airvault under the OPTEOR banner since 2006. It provides end-to-end services — boilerwork (chaudronnerie), industrial piping, metalwork, and industrial mechanics/maintenance — split ~60% maintenance / 40% design, with an in-house design office using AutoCAD, SolidWorks, and 3D point-cloud scanning. Working B2B-only across 18 departments in western France (zero export), it serves chemical, food, and energy industry clients, and partners with neighboring firm AROM for tungsten-carbide hardfacing (whose facility it acquired in 2022 for €45,000). Led by president Jacques Belaud since 2011, it employs ~26 people and holds MASE safety certification (renewed November 2025). Financially it staged a strong turnaround: revenue grew from €6.37M (2021) to a record €7.97M (2024)

Not assessable
Evidence ladder
Attacker assertion only. Establishes: claim date, group, alleged victim.
Unlocks: incident narrative, operational impact. Still no compliance clock.
Unlocks: discovery date, data types, affected count, compliance clock.
Unlocks: materiality, stated response, full audit trail. Ceiling removed.
No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.
