| Pricing model | Custom pricing based on endpoints, coverage scope, and service tier. Three tiers: Security Essentials (SMB vCISO + identity protection bundle), MDR + MSSP CORE (detection + IR retainer), MDR + MSSP MAX (full managed SOC + vulnerability management + email security). | Custom quote. SISA does not publish ProACT MDR package pricing. |
| Hidden cost warnings | Requires existing SIEM or purchase of SIEM platform (Rapid7, Tenable, Microsoft Sentinel). Technology-agnostic model means you need to own the underlying security tools. OT/ICS coverage requires separate Claroty, Dragos, or SCADAfence licensing. Third-party estimates (Getlatka) suggest ~$55K average deal size, which is mid-market territory, not SMB-friendly except for the Security Essentials tier. No published pricing on the website makes cost comparison difficult before engaging sales. Identity threat protection and vCISO are only in the Security Essentials tier (separate from MDR), not in CORE or MAX | Public pages do not publish MDR pricing, contract minimums or service-credit language..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. |

Awards show vendor credibility but tell you nothing about day-to-day service quality from a buyer's perspective. | 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. |
