Last year the data breach at Equifax compromised the records of over 140 million people. In the wake of the breach, Equifax offered consumers a year of free credit monitoring. This offer, which has also been made by other breached companies, helps people whose data may have been stolen take action against identity thieves who try to open fraudulent credit accounts. But what should you do once the free year of monitoring has passed? If your data was exposed in the Equifax hack or any other data breach, it’s still vulnerable and could be used to steal your identity at any time.

Three steps you could potentially take to protect yourself are credit freezes, credit locks, and credit alerts. Each has its pros and cons.

A credit freeze is a valuable tool for protecting your credit in case of a data breach. If you put a freeze on your credit report, a credit agency is prohibited from disclosing the report to anyone. Without the ability to check a credit report, lenders won’t extend credit to anyone attempting to open an account in your name.
