You will be monitoring device health, capacity, and telemetry fidelity to ensure consistent, forensically sound data capture. You will be managing PCAP retention strategies, indexing policies, and storage allocation across distributed deployments. You will be aligning Endace visibility architecture with Zero Trust telemetry requirements and continuous verification workflows.

You will ensure packet capture and telemetry support identity-aware network segmentation and policy enforcement. You will support the development of traffic baselines, segmentation decisions, and enforcement models using Endace data. You will automate deployment, configuration, and sustainment workflows using Ansible, Terraform, or scripting.
