Its a very complete extension, works very well i dont give 5 stars because it does not integrate with k2 (which i needed for my site) so i had to unistall it, aside of that its a great extension, recommended.
I was looking for a good security tool looked for others but turned out that some where either too expensive or too complicated, i first installed the basic version which helps a lot but the pro version is way better and the price is very acceptable.
It does have a lot of good options but, where do i start? where are the available tags? where do i put them?
There is no documentation on the developer site, searched their forum, nothing.
Seems great but for those who are trying something new, this is not the right choice, just because it lacks good clear documentation for beginners.
