Are Credit Monitoring services worth it?

Very interesting article:

Having purchased credit monitoring/protection services for the past 24 months — and having been the target of multiple identity theft attempts — I feel somewhat qualified to share my experience with readers. The biggest takeaway for me has been that although these services may alert you when someone opens or attempts to open a new line of credit in your name, most will do little — if anything — to block that activity. My take: If you’re being offered free monitoring, it probably can’t hurt to sign up, but you shouldn’t expect the service to stop identity thieves from ruining your credit.

Normally, I place fraud alerts on my credit file every 90 days, as allowed by law. This step is supposed to require potential creditors to contact you and obtain your permission before opening new lines of credit in your name. You merely need to file a fraud alert (also called a “security alert”) with one of the credit bureaus (Equifax, Experian or Trans Union). Whichever one you file with is required by law to alert the other two bureaus as well.

Most consumers don’t know this (few consumers know the names of the three main credit bureaus), but there is actually a fourth credit bureau that you should alert: Innovis. This bureau follows the same rules as the big three, and you may file a fraud alert with them at this link.

There's a lot more, all good info.
