January Security Tip: Scan Your Websites for Vulnerabilities

60% of website breaches involve vulnerabilities for which a patch was available but not applied. This means having software with known vulnerabilities installed on your site gives hackers the blueprints they need to take over your site.

Every day, it gets harder and harder to keep track of every disclosed WordPress vulnerability. You have to compare that list to the versions of plugins and themes you have installed on your site… and make sure you’re constantly updating.

To solve this problem, the iThemes Security Pro plugin just rolled out a better way to protect your sites against software vulnerabilities, the number one culprit of hacked and compromised WordPress sites.

The new, improved WordPress Security Site Scan powered by iThemes performs automatic checks for known website vulnerabilities and, if a patch is available, iThemes Security Pro will automatically apply the fix for you … so you don’t have to. Whew. that’s some peace of mind.
