Consult a Microsoft threat expert for more insights on a potentially compromised device, or already compromised devices.

Microsoft Threat Experts are engaged directly from within the Microsoft Defender portal for timely and accurate response. Experts provide insights on a potentially compromised device and help you understand complex threats and targeted attack notifications. They can also provide information about the alerts or a threat intelligence context that you see on your portal dashboard.

See Consult a Microsoft Threat Expert for details. The Action center provides information on actions that were taken on a device or file. You can view the following details:. Cyber security investigations are typically triggered by an alert.

Alerts are related to one or more observed files that are often new or unknown. Selecting a file takes you to the file view where you can see the file's metadata. To enrich the data related to the file, you can submit the file for deep analysis. The Deep analysis feature executes a file in a secure, fully instrumented cloud environment. Deep analysis results show the file's activities, observed behaviors, and associated artifacts, such as dropped files, registry modifications, and communication with IPs.

Deep analysis currently supports extensive analysis of portable executable PE files including. Deep analysis of a file takes several minutes. Once the file analysis is complete, the Deep Analysis tab will update to display a summary and the date and time of the latest available results. The deep analysis summary includes a list of observed behaviors , some of which can indicate malicious activity, and observables , including contacted IPs and files created on the disk.

If nothing was found, these sections will display a brief message. Results of deep analysis are matched against threat intelligence and any matches will generate appropriate alerts.

Use the deep analysis feature to investigate the details of any file, usually during an investigation of an alert or for any other reason where you suspect malicious behavior. This feature is available within the Deep analysis tab, on the file's profile page. Submit for deep analysis is enabled when the file is available in the Defender for Endpoint backend sample collection, or if it was observed on a Windows 10 device that supports submitting to deep analysis.

You can also submit a sample through the Microsoft Security Center Portal if the file wasn't observed on a Windows 10 device or Windows 11 , and wait for Submit for deep analysis button to become available. Due to backend processing flows in the Microsoft Security Center Portal, there could be up to 10 minutes of latency between file submission and availability of the deep analysis feature in Defender for Endpoint.

A progress bar is displayed and provides information on the different stages of the analysis. You can then view the report when the analysis is done. Depending on device availability, sample collection time can vary. There is a 3-hour timeout for sample collection.

The collection will fail and the operation will abort if there is no online Windows 10 device or Windows 11 reporting at that time. You can re-submit files for deep analysis to get fresh data on the file. View the provided deep analysis report to see more in-depth insights on the file you submitted. This feature is available in the file view context. Select the Deep analysis tab.

If there are any previous reports, the report summary will appear in this tab. If you come across a problem when trying to submit a file, try each of the following troubleshooting steps.
