| Pricing model | Per-user per month, tiered across 3 plans: MDR Auto (automated containment, devices and identity only), MDR Core (24/7 analyst investigation with approval-based containment), MDR Core Premium (fully managed response, proactive hunting, customisable SOAR). Starting price published as 'from £4 per user per month.' | Custom quote. SISA does not publish ProACT MDR package pricing. |
| Hidden cost warnings | Requires existing Microsoft licensing (at minimum Microsoft 365 Business Premium or equivalent Defender licenses). These costs are separate and are not included in CyberOne's fee.. Microsoft Sentinel runs in the customer's tenant, meaning Azure consumption costs for data ingestion are billed by Microsoft separately and can rise meaningfully during high-volume incidents.. Incident Response is a separate purchase. The MDR service handles detection and containment; full IR (forensics, eradication, recovery) requires a separate NCSC-accredited IR retainer.. Network coverage is limited. CyberOne is Microsoft-stack focused; organizations needing network or OT/ICS coverage will find significant gaps.. Threat hunting is Premium tier only. MDR Auto and MDR Core buyers do not receive proactive hunting. | Public pages do not publish MDR pricing, contract minimums or service-credit language..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 | No independent reviews found on G2, PeerSpot, or Gartner Peer Insights. Glassdoor employee reviews (30 reviews, 3.7/5) note a supportive culture but flag limited senior analyst headcount and management maturity. Client testimonials on the CyberOne website are positive but unverifiable. Zero Reddit presence. The company is a credible, CREST and NCSC-accredited Microsoft specialist, but lacks the third-party peer review validation that enterprise buyers typically require. | 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. |
