| Pricing model | Custom quote for Thales Cyber Detection and Response, Managed Security Services, SOC and MDR. Public prices are not published. | Fixed fee per endpoint. No log volume or retention surcharges. No public pricing for any tier. |
| Hidden cost warnings | The current S21sec domain routes to Thales-branded services, so buyers wanting legacy S21sec-specific delivery should confirm contracting entity, SOC location and delivery team.. Public pages do not publish prices, minimum terms, service credits, MTTD/MTTR or formal MDR SLAs.. Thales offers a broad cybersecurity services portfolio; buyers should separate base MDR scope from CTI, DRPS, DFIR, CERT, ICS monitoring and advisory services.. Named endpoint, identity and cloud containment actions are not public and should be confirmed tool by tool.. Data retention, raw log access, offboarding and detection-content export rights are not described publicly. | No public pricing for any tier, requires sales engagement for any estimate. IR is a separate retainer on Core and Enterprise, only Black includes it. US customers may get a different experience since bulk of 350+ specialists are in Europe |

| 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. | Effectively unrateable. No public reviews on G2, PeerSpot, or Gartner Peer Insights. Not in Forrester Wave or Gartner MQ for MDR. No Reddit mentions. Strong Nordic reputation based on vendor claims and partner references (EY, Microsoft MISA), but impossible to validate through independent peer feedback. |
