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. | Requires CrowdStrike Falcon EDR deployment. Cannot use a competing endpoint agent.. MDR is only available bundled with a Stoik insurance policy. No standalone MDR purchase option.. Sold through broker partners only.

| 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. | Almost no English-language reviews. 10,000+ insured companies and 200%+ YoY growth show market traction in continental Europe. Backed by a16z, Munich Re Ventures and Alven (~$78M raised through Series C in Jan 2026). Practitioner sentiment on MDR quality is impossible to gauge from public sources. |
