| Pricing model | Custom pricing based on environment size, coverage areas, and platform integrations. No public pricing information available. | 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 service from the Critical Insight division, likely priced separately.. OT/ICS coverage requires the NetWitness partnership (announced Feb 2026) and is not part of standard MDR. Pricing and maturity of this offering are unknown.. Roll-up strategy means the service you buy today may have been three different companies 13 months ago. Ask about integration status between Datashield, Netsurion, and Critical Insight operations.. Zero public pricing. No way to benchmark costs before a sales conversation.. Single US SOC in Scottsdale, AZ. No follow-the-sun coverage, which may affect overnight response quality. | Public pages do not publish MDR pricing, contract minimums or service-credit language..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 | Gartner Peer Insights 4.9/5 (25 reviews in Managed Security Services, 6 in MDR), but very small sample size. Virtually no Reddit or G2 discussion. Glassdoor 2.9/5 (25 employee reviews) with only 39% recommending and 22% positive business outlook. Compensation rated 3.3/5, down 17% year-over-year. The Gartner rating looks good on paper but the tiny review count and lack of independent practitioner discussion make it hard to assess real-world performance. | 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. |
