At a basic level, LifeLock is an identity theft monitoring service. LifeLock surveys and inspects locations, platforms, and services where your identity-related information (like Social Security number, credit card information, or driver’s license number) is stored. LifeLock will alert you to any suspicious behavior or indications that your information has been stolen.
Signing up for a LifeLock package does not guarantee that your identity won’t be stolen—the company is simply a watchdog for red flags.
