With HardyPress you can hide your WordPress installation from the bad guys and publish a static site for the rest of the world to see. HardyPress will create static copies of all of the pages from your WordPress installation, leaving no attack surface for malicious users!
Your WordPress installation only runs when an editor enters the Admin area to make some changes. For the rest of the time, your WordPress simply doesn’t exist. No PHP, no MySql, nothing that can break. You don’t even need to keep your installation updated if you don’t want to.
Your WordPress lives in a separate random-generated sub-domain and even if your hidden domain is leaked, your installation can be seamlessly protected by HTTP basic-auth.
