Re: PCI, verified..hacker safe?
This is why I like Comodo SSL certificates so much, the cert image is displayed in the lower right of every page on the site, scrolling along with the window. The customer sees the image every time. And, unlike the "hacker-safe" programs (which are highly scrutinized by the security community), SSL actually works.
On another note, it is not hard to do a little delving into security exploits to run against your own site. That is really all these hacker-safe programs do anyway. Many scripts exist for this - anybody with some experience in Linux/*BSD or related OS's can do it.
Make regular site and database backups!
