| Pricing model | Custom pricing based on environment size, coverage areas, and Microsoft licensing footprint. Offered via Azure Marketplace as managed service. Pricing model not publicly disclosed. | Custom quote. SISA does not publish ProACT MDR package pricing. |
| Hidden cost warnings | Incident response is NOT included in base MDR, it is a separate 24/7 service. Requires Microsoft Sentinel and Defender XDR licensing (customer cost). OT/ICS coverage requires specialist engagement beyond standard MDR. UK/Europe focus, US expansion underway but limited North American SOC presence historically. I-Tracing merger (May 2025) introduces integration risks during transition period | Public pages do not publish MDR pricing, contract minimums or service-credit language..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. |

| Community view | Limited public reviews due to CNI/government client base where testimonials are restricted. Published case studies from Northern Gas Networks and Manchester Airport Group praise technical depth and organized delivery. No G2/Gartner Peer Insights presence and zero Reddit mentions suggest limited visibility outside UK CNI and public sector markets. Hard to assess independently. | 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. |
