<p>Stop User Enumeration is a security plugin designed to detect and prevent hackers scanning your site for user login names.</p>
<p>User Enumeration is a type of attack where nefarious parties can probe your website to discover your login name. This is often a pre-cursor to brute-force password attacks. Stop User Enumeration helps block this initial attack and allows you to log IPs launching these attacks to block further attacks in the future.</p>
<p>Tools like WPSCAN are designed for use by ethical hackers and make efforts to find user login names. Ethical hackers ask permission first, this plugin is designed to reduce the tools when used without permission and when used in conjunction with fail2ban can block those attempts at the firewall.</p>
<p>If you are on a VPS or dedicated server, as the attack IP is logged, you can use (optional additional configuration) fail2ban to block the attack directly at your server’s firewall, a very powerful solution for VPS owners to stop brute force attacks as well as DDoS attacks.</p>
<p>If you don’t have access to install fail2ban ( e.g. on a Shared Host ) you can still use this plugin.</p>
<p>The plugin can stop the user id being leaked by the oEmbed API call.</p>
<p>Since WordPress 4.5 user data can also be obtained by API calls without logging in, this is a WordPress feature, but if you don’t need it to get user data, this<br />
plugin will restrict and log that too.</p>
<p>Since WordPress 5.5  sitemaps are generated by core WP  ( wp-sitemap.xml ) which includes a user/author sitemap that exposes the user id.  You can enable / disable this in the plugin settings.</p>

Works as a charm!

Helps secure your site against hacking attacks through detecting  User Enumeration

<p>This plugin checks for common user names that don’t exist in the users table.  If the submitted user name meets settings criteria the IP will be blocked from the site.</p>
<p>The plugin also has the ability to stop author enumeration by bots.</p>
<h4>Recommended Settings</h4>
<p>There are two different ways to protect your site from user name brute force attacks.  The more strict way is to immediately block an IP that attempts to login with a non-existent user name.  This can possibly cause issues with websites that have many users or users that may not login very often and forget their user name.  It’s most useful for one-person websites.</p>
<p>The less strict way is to have a black list of user names that only a bot would try like “admin” and user nicenames that aren’t logins.</p>
<p>The “Stop Enumeration” setting redirects all attempts to ?author={ID} to the home page of your site.  This will stop bots from incrementing through your users and discovering user nicenames.</p>
