| Pricing model | Custom quote. SISA does not publish ProACT MDR package pricing. | Per-endpoint/per-device/per-user subscription. Monthly or annual billing options. |
| Hidden cost warnings | Public pages do not publish MDR pricing, contract minimums or service-credit language..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. | Platform lock-in: requires WithSecure Elements EDR, cannot use competing EDR. Modular pricing: full coverage across identity, cloud, SaaS, and exposure management adds cost beyond base MDR. Ownership transition: being taken private by CVC/Siilasmaa, managed services ARR declined 22% in H1 2025 |
