This video shows how to submit suspicious files to Microsoft Defender for Endpoint for deeper analysis—so you can confirm whether something is malicious and improve detections over time. It walks through locating the file from alert context or the file entity page, then using the submission workflow to upload a sample, categorize it, add details, and send it to Microsoft for review. It also covers checking submission status and results, and when submissions are most useful—like unknown binaries, borderline detections, or files you believe are false positives/false negatives that need a second look.
We produced this as a simple, repeatable “do this every time” demo: straightforward narration, clean UI capture, and pacing tuned for follow-along. In post, we kept the focus on the handful of fields that matter so admins and analysts can submit samples quickly and confidently. Final delivery includes closed captions, audio description, and thumbnails.
The inevitable sequels
Hollywood keeps stretching good ideas into progressively worse sequels. We don’t. These are the related videos—spiritual siblings of the one you just watched—as good or better than this video. Expect callbacks, new plot twists, and maybe even a scene-stealing cameo from a lower third.
