| Pricing model | Per-user per-month pricing. Two tiers: Monitored (baseline Defender coverage, monthly reports) and Managed (extended functionality, automated threat responses, Teams-based monthly reviews). Contracts typically 12-36 months. Also available as committed annual contract with retrospective monthly management charge based on device count. | 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 retainer delivered through UK-based partners.. Automated containment triggers on critical alerts, but broader remediation is your team's responsibility. Budget for internal staff to act on SOC guidance.. Minimum spend threshold exists but is not publicly disclosed. Ask for it before engaging.. OT/ICS and advanced cloud coverage may be priced as additional modules beyond base MDR.. Managed tier costs more than Monitored, with significantly different automation and analyst involvement. Clarify which tier is being quoted. | Public pages do not publish MDR pricing, contract minimums or service-credit language..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 | NPS score of 88+ (vendor-reported, industry average 34) suggests high customer satisfaction among existing clients. However, virtually no public reviews on G2, Gartner, or Reddit exist, making independent validation impossible. Customers appear to value SC clearance and UK/government compliance focus. Small enough provider that community discussion is minimal. | 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. |
