| Pricing model | Custom quote. SISA does not publish ProACT 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| Hidden cost warnings | Public pages do not publish MDR pricing, contract minimums or service-credit language.. The service is heavily payment-security oriented, so non-payment buyers should confirm whether use cases fit their environment.. ProACT lists many stack components, including SIEM, EDR, CASB, UEBA, SOAR, threat hunting and dark web monitoring, so buyers should confirm which are included in the base quote.. Response automation is a major part of the pitch, so pre-approved SOAR actions and rollback rules should be documented before go-live.. DFIR and payment forensic services are adjacent SISA services, so buyers should confirm what investigation and response work is included in 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 | No meaningful MDR-specific buyer-review signal was found in major English-language review communities during this pass. The public buyer case rests on SISA's payment-security focus, ProACT Agentic SOC, forensic intelligence, 1,000+ customer claim, 40+ country footprint and PCI forensic-investigation credentials. Buyers should validate pricing, SOC delivery model, response authority and non-payment use cases directly. | 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. |
