| Community view | Ranked #1 service-based MDR in the 2024 Frost Radar and listed in Gartner's top 40 MDR providers. Praised for OT/ICS coverage and working with existing tools. Very limited practitioner reviews on G2, PeerSpot, or Reddit. Most validation comes from analyst reports rather than user feedback. | 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. |
