Netwrix Auditor allows you to apply tags when creating an alert. With alerts, you can distinguish one alert from another, create groups of similar alerts, etc.
The Tags page contains a complete list of alerts that were ever created in the product. To review the tag set and remove those that are no longer relevant, navigate to Settings → Tags.
Currently, you cannot assign or create tags on this page. To apply tags to an alert, navigate to alert settings and locate the Apply tags section on the General tab.
