I use this product on both my own websites and my clients’ sites, and I highly recommend it. It’s lightweight, runs smoothly, and is very effective. Under the hood, it leverages .htaccess, which has proven to be a highly efficient method for blocking attackers and bots. The web-based main console makes it easy to manage an IP blacklist that applies across all your websites—an especially valuable feature if you’re a web admin managing multiple client sites.
