Use the power of the cloud and a global CDN to restrict access to your login page.
CloudGuard brings global and cloud driven protection to your login page. Using Cloudflare’s free Geolocation service, this super lightweight plugin restricts access to your login page, allowing access to only your chosen countries. This means that any login attempts from the rest of the world will be automatically blocked.
Additionally, this plugin tracks any unauthorized login attempts and displays them on a <a href="https://wordpress.org/plugins/cloudguard/screenshots/" rel="ugc">world map</a> in your dashboard.
<h3>Main Features</h3>
<ul>
<li>Protect your login page globally.</li>
<li>Reduce server load.</li>
<li>Country based IP ranges constantly updated by Cloudflare.</li>
<li>Monitor login attempts via your dashboard.</li>
<li>Block access to the login page or redirect to a URL.</li>
</ul>
<h3>Why Cloudflare’s Geolocation?</h3>
There are other plugins which can restrict your login page by geographic location. However, these plugins use your server to detect the IP and compare this to a geographic location. This adds extra overhead to your site, takes up space on your server, and requires frequent updates to keep the IP list relevant.
CloudGuard is different. Since we leverage Cloudflare’s geolocation service, your server simply has to read the data, rather than compute and store it locally. Cloudflare does the grunt work, leaving your site safe, secure and optimized.
Note: This plugin requires that you have an account (including the free option) on <a href="https://www.cloudflare.com" rel="nofollow ugc">Cloudflare</a> with <a href="https://support.cloudflare.com/hc/en-us/articles/200168236-What-does-Cloudflare-IP-Geolocation-do-" rel="nofollow ugc">Geolocation</a> enabled.

CloudGuard

I consider it essential. You can do the same thing with Firewall Rules in Cloudflare this is highly visible in Wordpress' dashboard unlike Cloudflare's stats.

Love this plugin

WP-Memory-Usage is a lightweight but powerful WordPress plugin that monitors and displays memory usage directly in your WordPress admin area. 
It is essential for site administrators and developers who need to keep an eye on memory consumption, identify bottlenecks, and act before users are affected.
What the plugin shows:
In the admin footer (every admin page): 
* Current memory usage vs. WordPress limit (with percentage) 
* Current memory usage vs. PHP limit (with percentage) 
* Server IP address and server name 
* PHP version
In the Dashboard widget (“Memory Overview”): 
* PHP version, architecture (32/64 bit), max execution time 
* WordPress memory limit (WP_MEMORY_LIMIT), WordPress admin limit (WP_MAX_MEMORY_LIMIT), PHP memory limit 
* Current peak memory usage with a visual progress bar (colour-coded: green / orange / red) 
* Latest digest status summary (warn / danger / critical badges) 
* Link to the Threshold Alerts settings page
Settings & Monitor — Tabs (since 2.0.0):
<ul>
<li>Settings — thresholds, logging options, email alerts, log rotation</li>
<li>History — latest logged requests with full context (URL, type, user, memory)</li>
<li>Digest — aggregated summaries of past log intervals; browse, merge, and delete digest files</li>
<li>️Actions — practical guidance on what to do when you receive a memory alert</li>
<li>Diagnose (new in 2.1.0) — full PHP/WordPress configuration snapshot with a ready-to-paste AI prompt for analysis</li>
<li>Memory Thresholds — current limits, threshold assessment, and recommendations</li>
<li>Check Installation — verifies that the plugin can run correctly on your server</li>
</ul>
<h3>Why Use WP-Memory-Usage?</h3>
Excessive memory usage leads to slower sites, HTTP 500 errors, and failed background jobs (cron, imports, backups). WP-Memory-Usage gives you the information you need to act before users are affected — without overwhelming you with notifications.
<h3>Features</h3>
<ul>
<li>Real-time memory display in the dashboard widget and every admin page footer</li>
<li>Colour-coded progress bar (green / orange / red) for instant status recognition</li>
<li>Three alert levels: Warning, Danger, Critical — each configurable as a percentage of the effective memory limit</li>
<li>Flexible logging: Ajax, REST, Admin, Cron, favicon requests — log only what matters</li>
<li>Email alerts with configurable recipient</li>
<li>History tab: recent requests with full context (URL, type, admin screen, REST route, AJAX action, user)</li>
<li>Digest tab: aggregated interval reports — browse, merge, and delete digest files</li>
<li>Actions tab: plain-language guidance on resolving memory alerts, no developer skills required</li>
<li>Diagnose tab (new in 2.1.0): full configuration snapshot + one-click AI prompt (English, copy & paste ready)</li>
<li>Memory Thresholds tab: shows effective limits, threshold gaps, and concrete recommendations</li>
<li>Check Installation tab: verifies log directory, WP-Cron, PHP functions, disk space, and email setup</li>
<li>Admin bar indicator: quick status badge visible on every admin page</li>
<li>Multisite compatible</li>
<li>Clean uninstall: removes all options, cron jobs, database-tables and log files on deletion</li>
</ul>
