Bell Integration - Managed Detection and Response (MDR) Service

Bell's Managed Detection and Response (MDR) service provides 24x7 security monitoring, threat detection, investigation and response across your Microsoft security estate. Combining Microsoft Sentinel, Microsoft Defender XDR, advanced automation and expert UK based SOC analysts, the service helps organisations rapidly identify and contain cyber threats before they impact business operations.

The service continuously collects and correlates telemetry from cloud services, endpoints, identities, infrastructure and security platforms to deliver comprehensive visibility across your environment. Security events are enriched through advanced analytics, threat intelligence and automation to improve detection accuracy, reduce false positives and accelerate response times. Bell's MDR service combines automated threat detection with human-led investigation and threat hunting. When a confirmed threat is identified, response actions can be executed in accordance with an agreed response protocol, helping to minimise business impact while maintaining customer control over response decisions.

Our service also supports the monitoring, detection and investigation of security events across environments hosted on AWS. The service can ingest and analyse telemetry from a range of AWS services.
