| Pricing model | Custom quote. Tesorion does not publish MDR package pricing. | Fixed fee per endpoint. No log volume or retention surcharges. No public pricing for any tier. |
| Hidden cost warnings | Public pages do not publish response SLAs or named default response actions..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. | No public pricing for any tier, requires sales engagement for any estimate. IR is a separate retainer on Core and Enterprise, only Black includes it. US customers may get a different experience since bulk of 350+ specialists are in Europe |

| Community view | 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. | Effectively unrateable. No public reviews on G2, PeerSpot, or Gartner Peer Insights. Not in Forrester Wave or Gartner MQ for MDR. No Reddit mentions. Strong Nordic reputation based on vendor claims and partner references (EY, Microsoft MISA), but impossible to validate through independent peer feedback. |
