## Why this matters

Outside ad scripts increase the number of parties executing code while you read a page. Privacy is easier to defend before this information is collected than after it has spread.

## The protection

Shields blocks many third-party ad resources and can replace certain problematic scripts with more private versions.

## Take action

Use Shields as one layer of defense and keep the browser updated. First-party scripts and unblocked resources may still run. Brave reduces common tracking, but a site you sign in to still knows what you do there. Ordinary browsing also reveals your IP address to the destination.
