A new PAY service is coming from Wordpress, called VAULTPRESS. It is about keeping your blogs/server secure, and may be of interest.
Right now it is into beta testing, but you can apply for a chance to test it. The proposed cost is about $10 a month, but you can find more details HERE.
I’ve signed up for a beta test on one of my adult blogs. Be interesting to see if it gets accepted, and if it works. Supposedly will keep it safe from harmful plugins, themes, and core files, without me lifting a finger.
