Brave browser includes a built-in safety check by which you can check if your browser is updated, the add-ons are safe and safe browsing settings are enabled.
Here is how to access and use it:
Open Brave browser and open the Privacy settings:
Scroll down to the bottom and from the Safety check section, click on Check now.
This safety check tool will perform a series of checks and determine if the browser is updated, the installed add-ons are safe and if safe browsing is on.
If you are using third-party privacy and network add-ons, then the safe browsing could be off indicating that it is controlled by an external add-on. You can also click on these results to open related settings.
Happy and safe browsing.
