This plugin has become one of my favorite plugins, it protects my website from malicious users, and the development team provides support very quickly! Thanks!
長年、SiteGuardを使っていましたが、たまにログインできなくなってプラグインをサーバーから削除とかしたりだったので、こちらのプラグインを使い始めました。
設定画面もわかりやすく、作動も安定していて、ログイン試行履歴とかも見れます（結構不正ログインされようとしているのがわかって楽しい）、随時他のサイトのセキュリティプラグインもこちらに切り替えていこうと思っています。感謝感謝
ログイン関係にとどまらず、WordPress全体としてのセキュリティプラグインへの進化を期待します。
This plugin does its job well and clean. Another thing I Love bout this plugin is the lightness. Keep up da good work guys!
This is awesome plugin!
It has all the features I need and is very easy to use.
I was able to change the login URL with Nginx.
すばらしいプラグインです。
