This is awesome plugin!
It has all the features I need and is very easy to use.

Awesome!

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

とても良い


This one plugin completes my security measures. Thanks !!

<p>Secure your site’s XML-RPC by removing some methods, instead of disabling totally XML-RPC, which is needed by some plugins (eg. Jetpack) and some mobile apps.</p>
<h4>Features</h4>
<p>Removes the following methods from XML-RPC interface.</p>
<ul>
<li>system.multicall</li>
<li>system.listMethods</li>
<li>system.getCapabilities</li>
<li>pingback.extensions.getPingbacks</li>
<li>pingback.ping</li>
<li>X-Pingback from HTTP headers</li>
</ul>
<p>This is not perfect, but it will help prerventing attacks</p>
<h4>Requirements</h4>
<ul>
<li>WordPress 5.0 or higher.</li>
</ul>
