| 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. Tesorion does not publish MDR package pricing. |
| 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. | Public pages do not publish response SLAs or named default response actions.. The public MDR page says mitigation is immediate where possible, but does not specify what Tesorion can do without customer approval.. T-CERT incident response is prominent, but buyers should confirm whether IR hours are included in MDR or sold separately.. Tesorion lists broad coverage across domains, so buyers should confirm which monitored sources are included in base MDR. |

| 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. | Tesorion has limited MDR-specific public review volume. The public buyer case rests on Dutch delivery, T-SOC operations, XDR and SOAR correlation, threat intelligence and nearby T-CERT incident response. Buyers should validate pricing, response authority, included source scope and whether T-CERT support is included before signing. |
