How to Compare Free Credit Monitoring Offers

Given the frequency and scale of cyberattacks affecting U.S. companies, it's likely your information has been or will be caught up in a data breach. And as we've seen in the past, companies that have experienced breaches usually offer their customers some sort of free credit monitoring or identity theft protection plan to help deal with the aftermath. If you've been involved in multiple breaches, then you may have received multiple offers for free credit monitoring from different companies which provide the service. But which ones should you sign up for, and how do the different plans compare to one another?

"You need to read what you're actually being offered," said Adam Levin, identity theft expert and chairman and co-founder of Credit.com. "In some of these offers, they're kind of vague, so you need to say, 'What am I actually getting, and how do I sign up for whatever it is?'"

Some people opt into all of the plans they are offered — they may have different coverage periods, and different services are offered by different plans. Others may prefer to keep things simple and choose only one. Regardless of your choice, here are a few things to consider when reviewing your options.

What Data Does the Service Monitor?

Most consumer credit data (in addition to public records and other consumer information) are reported to the three major credit reporting agencies: Equifax, Experian and TransUnion. Some credit monitoring services review what's happening on all three credit reports, and some offer only single-bureau monitoring. Because data varies among agencies, three-bureau monitoring is more valuable.

Monitoring services have several levels of detail, and the more closely your data is analyzed, the more helpful it is likely to be to you.

Some monitoring services review summaries of your credit report, which are known in the industry as "header files."

"It would be the same as looking through the table of contents instead of reading the book," said Michael Bruemmer, vice president of consumer protection for Experian. Experian's ProtectMyID products have been offered by some companies that experienced data breaches, including Target and Premera.

Header file monitoring means a consumer would be notified if there was a change in the number of accounts on the person's credit report, if there have been new inquiries or if debt levels have increased. A credit monitoring service may or may not include checking for changes in all aspects of a report.

"In some cases the monitoring is only looking for maybe new credit openings," Bruemmer said. "It may not look at inquiries, it may not look at public records, it may not look at account takeover actions."
