There’s a lot of WordPress security plugins with many many options and pages to setup. And that is fine if you know what to do. 
But most of the times, you don’t need so much or simply you’re not sure about what to set or not.
This plugin adds some extra security to your WordPress with only one click. No options page, just activate it!
<h4>Features</h4>
Like many other security plugins SAR One Click Security adds well known .htaccess rules, but only the ones probed to be safe to use in almost any type of site (including WooCommerce stores), to protect your WordPress from common attacks. This allows you to have a safer WordPress without worries about what protection you should be using.
<ul>
<li>Turn off ServerSignature directive, that may leak information about your web server.</li>
<li>Turn off directory listing, avoiding bad configured hostings to leak your files.</li>
<li>Blocks public access (from web) to following files that may leak information about your WordPress install: .htaccess, license.txt, readme.html, wp-config.php, wp-config-sample.php, install.php</li>
<li>Blocks access to wp-login.php to dummy bots trying to register in WordPress sites that have registration disabled.</li>
<li>Blocks requests looking for timthumb.php, reducing server load caused by bots trying to find it. (*)</li>
<li>Blocks TRACE and TRACK request methods, preventing XST attacks.</li>
<li>Blocks direct posting to wp-comments-post.php (most spammers do this) and access with blank User Agent, reducing spam comments a lot and also server load.</li>
<li>Blocks direct access to PHP files in wp-content directory (this includes subdirectories like plugins or themes). Protecting you from a huge number of 0day exploits.</li>
<li>Blocks direct POST to wp-login.php and access with blank User Agent, preventing most brute-force attacks and reducing server load.</li>
<li>Blocks access to .txt files under any plugin/theme directory to prevent scans for installed plugins/themes.</li>
<li>Blocks any query string trying to get a copy of the wp-config.php file.</li>
<li>Blocks gf_page=upload query string argument, this was deprecated in Gravity Forms on May 2015, if your copy of Gravity Forms still uses it, update now!</li>
<li>Removes version information from page headers. This includes not only the page header (html or xhtml) but also feed headers (rss, rss2, atom, rdf) and opml comments. Only the version number is removed, not the entire generator information. </li>
</ul>
(*) If your theme uses TimThumb, you can disable that blocking rule, check FAQ before installing the plugin to see how.
<h4>Requirements</h4>
<ul>
<li>WordPress 3.9.2 or higher. (Works with WordPress network/multisite installation).</li>
<li>Apache 2.4.x web server</li>
</ul>
It has been tested in many servers including large providers like HostGator, Godaddy and 1&1 with optimal results, and it will work fine in any decent hosting service (that allows you to set options from .htaccess files).
Anyway, if you get any problem after activating the plugin, check FAQ for instructions on how to manually uninstall it.
If you’re not sure of which server is your hosting company using or if they allow to use custom .htaccess rules, I would recommend you to contact with your host support before installing the plugin.
<h4>Usage</h4>
To apply above mentioned security rules simply install and activate the plugin, no options page, no user setup!
If you need to remove the security rules for some reason, simply deactivate the plugin. If you want to add them again, activate the plugin again, that easy 😉
And remember, if your theme uses TimThumb, check FAQ before installing the plugin.

NETSENSAI Shield offers a range of security features, including:
Changing the login URL to reduce brute force attack risks.
Disabling the REST API (WP API JSON) for non-logged-in users.
Disabling XML-RPC to prevent unauthorized access.
Disabling the WordPress file editor to avoid accidental or malicious changes.
Disabling Application Passwords to block unauthorized API access.
Applying advanced HTTP security headers (e.g., HSTS, X-Frame-Options, Content-Security-Policy).
Integration with W3 Total Cache:
Permanently disable .htaccess writes by W3TC
Runtime disabling of Page Cache UI
One-time full cache flush on first admin page load
Automatic cache flush on Secure Options save
Physical cleanup and permanent disable via the W3TC API
Suppression of Site Health REST API availability notices for non-logged-in users (removes false Site Health errors while maintaining full API blocking).
In addition, the plugin provides helpful user feedback:
Email notifications when the login URL changes – sends a localized HTML email (Polish or English) with your old and new login links, change date and the plugin logo, so you remember to update your bookmarks.
Admin popup when disabling the WP API JSON – displays a friendly modal warning that disabling the REST API may break plugins like WooCommerce or contact forms. The popup includes a purchase link to upgrade to the PRO version if you need this feature without losing functionality.
Scoped styling – the custom colour for the “Save changes” button is now limited to the Secure Options page, so other admin pages keep the default WordPress look.
Promotional banner assistant – notifies administrators of summer discount codes and NETSENSAI Shield PRO features.
The free version provides both core and advanced Level 3 security functionalities. A PRO version offers extended support, additional features, and automatic protection enhancements.
