It’s my top recommendation for security plugins on WordPress sites.It includes all the security features I need.

タイトル通りです。AIOS等の定番プラグインと比べると機能は少ないですが、必要最低限の対策が揃っており設定が非常にわかりやすいので使いやすいです。これだけでは不安という人はBBQ Firewallを併用すると良いです。

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
