Some price sensitivity for SMBs and occasional SOC response delays on non-emergency tickets. | 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. |
