Now Facebook users, 50 million, got hacked. I don't know how you feel about all this hacking, but I feel like it will never end. It's one thing to have a "toy" we use hacked, something much more serious when it's a financial provider we use. If you didn't already, you need to check your credit once each year from each of the three major credit reporting firms (Experian, TransUnion and Equifax). So yes, that equals three checks per year.
Hiring a third party company, i.e., LifeLock, will not guarantee your identity or funds will never be stolen. What a firm like LifeLock will do is identify the fraudulent activity quickly and provide recovery services.
