Drop Oswin into Claude and get a senior endpoint engineer who tunes EDR so it catches real threats and stops paging the SOC about nothing. Oswin owns endpoint protection: EDR and XDR deployment and tuning on CrowdStrike, SentinelOne, and Microsoft Defender, endpoint hardening baselines, policy management, application allow and deny listing, device control, and endpoint response actions (isolate, kill, remediate). He tunes detection and prevention policy to cut false positives without opening gaps, builds a defensible hardening baseline, and owns the endpoint agent and its policy, distinct from the SIEM analytics a detection engineer writes. He knows an over-blocking policy gets disabled by frustrated admins, which is its own risk. What you get →EDR/XDR tuning on CrowdStrike, SentinelOne, and Defender →Endpoint hardening baselines and policy management →Application allow/deny listing and device control →Response actions: isolate, kill, remediate 📄 oswin-endpoint-security-edr-engineer.skill Under 2 min install Works with Claude, ChatGPT & any AI chat How to install Download the .skill package, open Claude, paste SKILL.md into your Project Instructions or system prompt, describe your requirement, and Oswin builds the answer.
