Compass Security Managed Detection and Response (MDR) is a 24/7 security monitoring and incident response service built on Microsoft's cloud-native XDR technologies. The service is designed to detect and respond to threats across endpoints, networks, cloud environments, and mobile devices. The service covers monitoring of devices, user behavior, system behavior, and network interactions. It supports endpoints including laptops, desktops, servers, cloud environments, and mobile devices across major operating systems and cloud providers. The response capability includes endpoint isolation, evidence and artifact collection from endpoints, and deployment of new detection rules. Digital Forensics and Incident Response (DFIR) is an integral component of the offering. The service is deployed within the customer's own Microsoft tenant environment. Rule sets and automations are handed over to the customer and maintained within their tenant subscription. Compass Security centrally manages updates across customers. Customers have direct access to an MDR and DFIR hotline staffed by specialists, without routing through a call center. On-call coverage is available around the clock for both remote and on-site response. The service is structured with contract models tailored to small and mid-sized businesses (SMEs). Micro-businesses can opt for basic endpoint-based tiers, while SMEs can choose bundled subscription packages. The service can be scaled incrementally, starting with a small user group. An annual benchmark is included to assess and improve resilience against cyberattacks. Compass Security's background in penetration testing and red teaming informs the detection strategy.
