MDR service providers leverage security technologies, including SIEM, EDR, and network analytics, to collect and analyze security data. They also employ skilled security analysts who analyze alerts, investigate potential threats, and provide incident response guidance to organizations. MDR services are designed to enhance an organization's security posture by augmenting internal capabilities with external expertise and resources.
