| Pricing model | Custom pricing based on deployment complexity, data volume, and coverage scope. Three one-time deployment packages published on their website: Essential ($25K-$50K), Advanced ($50K-$100K), Security Transformation ($75K-$100K). Ongoing managed services pricing not published. | Custom quote for Thales Cyber Detection and Response, Managed Security Services, SOC and MDR. Public prices are not published. |
| Hidden cost warnings | Deployment packages ($25K-$100K) are one-time setup fees on top of ongoing MDR subscription, which is not publicly priced. Google Chronicle SIEM and SOAR licensing costs may be separate from Foresite's managed service fees -- clarify who holds the Chronicle license. Data ingestion costs scale with log volume on Chronicle platform, which can grow unpredictably. Specific response actions available through SOAR playbooks are not publicly documented -- ask exactly what containment actions they can execute. Single SOC site in Kansas means no geographic redundancy or follow-the-sun coverage | 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 Public pages do not publish prices, minimum terms, service credits, MTTD/MTTR or formal MDR SLAs..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. |

Available feedback highlights strong technical support and effective communication. Small provider (~80-96 employees) with regional Kansas focus and heavy Google Cloud positioning means limited visibility outside the Google ecosystem. | 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. |
