No problem with compatibility. No slow page loads. Easy to install and configure. Does a great job protecting my site. The biggest plus is the support. I ran into a log in problem and sent a support ticket for help. Less than 24 hours later, Paul responded. His solution was perfectly accurate. What impressed me was the fact that this was a holiday weekend and still Paul felt I was important enough to help right away. Thanx Paul. I highly recommend this product.
