| Pricing model | Per-user per month, tiered across 3 plans: MDR Auto (automated containment, devices and identity only), MDR Core (24/7 analyst investigation with approval-based containment), MDR Core Premium (fully managed response, proactive hunting, customisable SOAR). Starting price published as 'from £4 per user per month.' | Custom quote for Thales Cyber Detection and Response, Managed Security Services, SOC and MDR. Public prices are not published. |
| Hidden cost warnings | Requires existing Microsoft licensing (at minimum Microsoft 365 Business Premium or equivalent Defender licenses). These costs are separate and are not included in CyberOne's fee.. Microsoft Sentinel runs in the customer's tenant, meaning Azure consumption costs for data ingestion are billed by Microsoft separately and can rise meaningfully during high-volume incidents.. Incident Response is a separate purchase. The MDR service handles detection and containment; full IR (forensics, eradication, recovery) requires a separate NCSC-accredited IR retainer.. Network coverage is limited. CyberOne is Microsoft-stack focused; organizations needing network or OT/ICS coverage will find significant gaps.. Threat hunting is Premium tier only. MDR Auto and MDR Core buyers do not receive proactive hunting. | 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 Public pages do not publish prices, minimum terms, service credits, MTTD/MTTR or formal MDR SLAs..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. |

| Community view | No independent reviews found on G2, PeerSpot, or Gartner Peer Insights. Glassdoor employee reviews (30 reviews, 3.7/5) note a supportive culture but flag limited senior analyst headcount and management maturity. Client testimonials on the CyberOne website are positive but unverifiable. Zero Reddit presence. The company is a credible, CREST and NCSC-accredited Microsoft specialist, but lacks the third-party peer review validation that enterprise buyers typically require. | 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. |
