This role involves mentoring and guiding SOC analysts, conducting proactive threat hunting, and collaborating with various internal teams to ensure a robust security posture. The MS Defender will also be responsible for fine-tuning security alerts, maintaining incident response playbooks, executing containment and remediation actions, and integrating threat intelligence to stay ahead of emerging threats. This position offers an excellent opportunity for security professionals eager to work in a dynamic environment focused on cutting-edge cybersecurity practices.

Executing containment and remediation actions via Microsoft Intune and Defender features, such as device isolation and investigation package collection, is a key part of the role. Additionally, the MS Defender will work closely with internal stakeholders through Microsoft Security Center and Compliance Center to ensure coordinated security efforts.
