Proactively identify and present recommendations to optimize IT systems, Microsoft Azure resources, M365 environments, and network security posture. Cybersecurity & Risk Management Contribute to and monitor cybersecurity frameworks, including the NIST CSF, Microsoft 365 security services (Defender for Endpoint, Defender for Office 365, Conditional Access, Intune), and Zero Trust principles. Conduct vulnerability assessments and penetration testing to identify and remediate risks across servers, endpoints, networks, firewalls, and security appliances. Utilize SIEM and XDR tools for threat detection, correlation, and incident response. Implement identity and access management (IAM) best practices, including Entra ID security policies, Conditional Access, and Intune compliance policies.
