Thales offers a broad cybersecurity services portfolio; buyers should separate base MDR scope from CTI, DRPS, DFIR, CERT, ICS monitoring and advisory services..

| Community view | Public Gartner Peer Insights pages show a 5.0 average for Daylight Security as of May 2026, but review volume is still light compared to established MDR vendors. Coverage on G2 and PeerSpot is thin, and Reddit presence is minimal. | 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. |
