SiteDove Free is a powerful tool for beefing up the security of your website at NO COST. It includes a unique Burglar Alarm that shows you when changes are made to files on your site. If you're not sure who made those changes, you will want to investigate to see if your site has been hacked.
In this way, SiteDove Free acts as an early warning system that can detect malicious attacks long before search engines and your readers encounter them.
SiteDove Premium includes a more powerful version of the Burglar Alarm, plus many more valuable features to keep your sites secure against hackers.
