GDMME recommended actions
GDMME recommendations · automatically organised from explicit products and source signals, without individual human analysis. Confirm applicability against vendor guidance and your environment.
- Locate Microsoft Edge deployments, running versions and service owners in your inventory or management console; compare them with the vendor applicability criteria. A named product does not mean every deployment is affected.
- For Microsoft Edge, confirm that updates are applied through central management or device checks. When the vendor requires it, reopen the browser/application or restart the device, then verify the running version rather than merely the downloaded update.
- Review company browser policies and installed extensions for Microsoft Edge, keeping approved items only. Do not lower protections for suspicious installation prompts; send the URL and screenshot to IT for verification.
