  • Support threat-hunting operations by implementing security controls and countermeasures across both on-premises and cloud assets.
  • Manage the complete lifecycle of endpoint security tools, ensuring seamless operation and integration within a hybrid architecture.
  • Remove or manage local administrative rights on endpoints to reduce the attack surface.
  • Ensure the health and compliance of all managed devices, remediating any that are out of compliance.
  • Collaborate with IT, Cloud, and other security teams to streamline endpoint management and improve automation across the hybrid estate.
