| Hidden cost warnings | Requires Microsoft licensing (E3/E5 or standalone Defender licenses) as a prerequisite. These costs are separate and can be significant.. Microsoft Sentinel consumption costs are usage-based and billed separately by Microsoft. Data ingestion charges can spike unpredictably.. Identity coverage (ITDR) and data security (Clarity Data) are separate services at lower tiers. AWS and GCP coverage only available in Clarity Protect (top tier) | Public pages do not publish response SLAs or named default response actions..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 | Named in the Gartner Market Guide for MDR as Representative Vendor (2024, 2025). Microsoft Security MSSP of the Year 2025. First UK Microsoft Verified MXDR provider. Very limited independent review data: no ratings on G2, PeerSpot, or Gartner Peer Insights with sufficient reviews. Zero Reddit presence. | 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. |
