LifeLock is more expensive than some other identity-protection services. Costs can add up quickly if you want to add another adult or children. The service also auto-renews, which can be a convenience — or a nuisance. If you're on a tight budget, consider using free ID theft prevention services to make yourself less of a target.

For its high cost, LifeLock offers disappointingly little. It reserves tri-bureau credit monitoring for its most expensive plan, Ultimate Plus. Additionally, LifeLock offers no cybersecurity features despite being operated by a digital security company. Despite its shortcomings, there are a few things to like about LifeLock.
