At its initial run, NortonLifeLock says it runs a historical analysis on your details, looking back as far as 2008 to find out if information about you or related to you has been exposed, and then to run continuous checks once you're a paid subscriber to the service. Information can't be erased, and it's not yet known if positive checks for the information could be provided to other services if they are leaked, such as a credit service or banks. However NortonLifeLock says that if your information is detected, you may be advised to do things to remedy the situation, such as changing your password or switching to multi-factor authentication, as well as reviewing financial statements and going to paperless deliveries where available. Norton offers a list of tips on its website, as while it can't remove information about you from dark web sources, the service aims to help you quell any issues before they pop up.
