| Community view | Gartner Peer Insights 4.4/5 (21 reviews). NTT DATA (parent group) ranked second by revenue in Gartner Market Share Analysis for Managed Security Services Worldwide 2022. Reviewers praise responsiveness, team continuity, and global reach. Recurring complaints: expensive pricing, alert severity over-classification, and inconsistent analysis quality across SOC regions. Very limited Reddit/community discussion. | 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. |
