Maintain and enhance operational security documents such as incident procedures, playbooks, standard operating guidance, and response runbooks.

Prepare recurring security reports and metrics covering incidents, threat trends, vulnerabilities, and operational performance.

Support audit requests, compliance reviews, eDiscovery efforts, and third-party security assessments as part of ongoing governance activities.

Partner with security, infrastructure, and support teams on daily operations, tabletop exercises, and continuous improvements informed by incident findings.

Strong knowledge of securing Microsoft 365, cloud services, identity platforms, and endpoint environments.
Hands-on background with identity and access management, access governance, and privileged access controls.

Experience with vulnerability management practices, remediation coordination, and endpoint compliance monitoring.
Familiarity with tools such as CrowdStrike Falcon, Microsoft Sentinel, Okta, Microsoft Entra ID, or comparable security platforms.
