| Hidden cost warnings | Public pages do not publish MDR pricing, contract minimums or service-credit language..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. | The MDR and MXDR pages describe different coverage depth, so buyers should pin down which tier is in the order form.. Microsoft Sentinel data ingestion and retention can materially affect total cost.. Public pages do not publish response SLAs or named default response actions.. UK-onshore and security-cleared delivery may be valuable for regulated buyers but can make pricing less comparable with lower-cost global MDR providers. |

| 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. | Six Degrees has limited MDR-specific community signal. The public buyer case is strongest for UK-onshore delivery, Microsoft security tooling and regulated-sector fit. Treat public claims around containment and response as credible enough for MDR eligibility, but confirm the exact tier, response authority and Microsoft cost model during procurement. |
