Remove all traffic for a specific user agent

Question

Is there a way to exclude, from all properties and all views of Google Analytics, the visitors with a specific user agent?

Note: it's not for spam/bot prevention (I already checked the feature Admin > View settings > Bot filtering > Exclude all hits from known bots and spiders), it's to remove a part of own traffic. I can't use IP filtering because my IP changes all the time, and I use many devices (mobile/desktop/laptop). I also can't use cookies, because often I want to test my website as a random non-logged user. I didn't find anything even after exploring deeply the Analytics UI. Maybe this requires API ?

In the first step you have to get the User Agent into Google Analytics. You can do this with the Tag Manager, by creating a custom Javascipt. This can return the User Agent and you can send it to GA with a custom Dimension or a Event. (It´s also possible to do this without the GTM).

1. Log in to the Tag Manager and navigate to Variables
2. Now we have to add a Javascript Variable. The User Agent is stored in the navigator.userAgent property

3. Now we have to push this data into the Google Analytics Account. We could do this with a custom Dimension or a Event. In this example we take a Event. As Action we send the Page Path - you don´t have to do this, but maybe it´s helpfull later for some reports. As a Trigger we define "All Pages" so the event is fired with every pageview. The User Agent we send as a Event Label.

If you have this information in GA you can add a filter on Account Level (for alle Views and Propertys). Filter Type = Custom > Select the Event or Dimension > Type the User Agent to exclude.

We can see the User Agent of the Users visited our site now in GA Behavior > Events > Top Events > Search for the Event Category (namend in Tag Manager (in our case "User Agent"))

In the last step we exclude the User Agent from all our Propertys and Views. Admin > All Filters (In the Account column) > "+ Add Filter" > Filter Type = Custom > Exclude > Select "Event Label" in the Dropdown > specify the User Agent to ignore

Select the Views, there this User Agent should be ignored > DONE
