Data retention, raw log access, offboarding and detection-content export rights are not described publicly. | Platform license ($179.99-$229.99/endpoint/year) is required before MDR, significant prerequisite cost.

| Community view | The current public evidence is strong for Thales-branded global SOC, MDR, CTI, DFIR and critical-infrastructure detection and response, but weak for S21sec as a standalone public MDR brand. Buyers should validate current delivery model, SOC location, response authority, pricing and whether the contract is with Thales/S21sec in the relevant country. | PeerSpot: Vigilance 8.6/10 but MDR market share declined 7.0% to 3.7% YoY (Feb 2026). G2: Vigilance Respond listing exists, 4.7/5 company rating. Gartner: Customers' Choice 2025 for XDR (97% recommend). MITRE Managed Services: 100% detection, best signal-to-noise ratio. Platform technology highly praised but MDR service gets mixed feedback, with support quality and false positive tuning as top complaints in 2026. |
