| 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 Public pages do not publish prices, minimum terms, service credits, MTTD/MTTR or formal MDR SLAs..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. | Tu Empresa Segura SMB pricing (EUR 3.99/month) only available in Spain and Chile. Not offered globally.. Enterprise NextDefense MDR pricing not published. Expect custom quotes with limited negotiation leverage due to sparse public benchmarks.. Primary EDR integration is CrowdStrike. Palo Alto Cortex XDR is supported, but other EDR platforms may have limited or no integration.. Telefonica parent company suffered a data breach in January 2025 (Hellcat ransomware, 2.3GB leaked). Ask about security posture improvements.. DFIR may be a separate retainer depending on tier.

| 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. | Ranked #2 on MSSP Alert Top 250 Global MSSPs (2023). IDC MarketScape 'Major Player' for European MDR (2024). Included in Forrester Wave for European MSS (Q3 2022). Almost no English-language reviews on G2, Gartner Peer Insights, or Reddit. Strong brand in Spain and Latin America, largely unknown in North American MDR market. Parent company Telefonica suffered a data breach in January 2025 (Hellcat ransomware group). |
