Continuous Threat Exposure Management (CTEM) : Leading the design and operationalization of a CTEM program that provides continuous visibility into the organizations cyber exposure. This includes threat exposure analysis attack path analysis validation of remediation through testing and risk-based prioritization to ensure critical issues are addressed first.. The resource will strengthen coordination between CTEM SOC and vulnerability management workflows ensuring that exposure findings translate into actionable improvements in monitoring detection and response.
