SolverGuard Spam Shield is the only free WordPress plugin that protects every entry point of your site — contact forms, comment sections, user registrations, login page, REST API, XML-RPC, and your server itself — with zero shortcodes and zero per-form configuration required.
While most anti-spam plugins protect only one area of your site, SolverGuard deploys 30+ independent protection layers across six major modules. Install it, activate it, and your entire WordPress site is defended immediately.
<blockquote>
“Set it and forget it” protection — works automatically from the moment you activate.”
</blockquote>
<h4>🛡️ MODULE 1: Contact Form 7 Protection</h4>
Six independent spam-fighting layers apply automatically to every CF7 form on your site — no per-form setup needed.
<ul>
<li>🍯 Honeypot — An invisible hidden field is silently injected into every form. Real users never see it or fill it in. Bots that auto-fill every field get caught instantly and blocked.</li>
<li>⏱ Time-Based Check — Bots submit forms in milliseconds; humans take a few seconds to read and fill out a form. This module blocks submissions that arrive suspiciously fast (bots) or from stale, expired sessions, eliminating both automated attacks and session replay attacks.</li>
<li>🚫 IP Blocker — Block individual IP addresses or entire CIDR network ranges (e.g. <code>10.0.0.0/8</code>) from submitting any form on your site. The same block list is automatically shared with comments, login, and registration protection for maximum coverage.</li>
<li>🔤 Keyword Filter — Case-insensitive keyword and phrase matching scans every submitted form field simultaneously. Block spam phrases, competitor names, casino/pharma keywords, or any custom list of prohibited terms.</li>
<li>📈 Rate Limiter — Caps the number of form submissions per IP address within a configurable sliding time window. Stops bots that submit the same form hundreds of times per hour, without ever impacting real users.</li>
<li>🤖 Google reCAPTCHA v3 — Silent, frictionless bot scoring via Google’s reCAPTCHA v3. No annoying checkboxes or image puzzles for real visitors — the score is calculated invisibly in the background and submissions below your threshold are blocked automatically.</li>
</ul>
<h4>💬 MODULE 2: Comment Spam Protection</h4>
Ten layers of dedicated comment spam protection, covering every submission path including Gutenberg and headless REST API setups.
<ul>
<li>🍯 Comment Honeypot — A hidden anti-spam field is injected into every WordPress comment form automatically.</li>
<li>⏱ Comment Time Check — Blocks comments submitted too quickly after page load (bots) or from sessions that expired too long ago.</li>
<li>🚫 IP Blocking — Automatically reuses the shared IP block list — block an IP once, block it everywhere.</li>
<li>📈 Comment Rate Limiter — Separate per-IP rate limiting specifically for comments, independent of form rate limiting.</li>
<li>🔤 Comment Keywords — A global keyword list plus comment-specific blocked phrases. Stop spam before it reaches your moderation queue.</li>
<li>🔗 Link Count Limit — Block comments containing more than a configurable number of hyperlinks — the #1 hallmark of spam comments.</li>
<li>📧 Email Domain Blocking — Block registrations and comments from disposable or known spam email domains. Enter a list of blocked domains and all matching email addresses are automatically rejected.</li>
<li>🤖 User-Agent Filtering — Block comments from known spam bot user-agents. Optionally block requests with no user-agent header at all.</li>
<li>⏳ Hold Comments With Author URL — Automatically sends comments from authors with a URL in their display name to moderation, rather than publishing them instantly.</li>
<li>🌐 REST API Protection — All comment spam checks also apply to submissions made via the WordPress REST API (used by Gutenberg and headless/decoupled WordPress setups).</li>
</ul>
<h4>🔐 MODULE 3: Login & Brute-Force Protection</h4>
Stop hackers from guessing your password with automated brute-force attacks.
<ul>
<li>🔒 Login Rate Limiting — After a configurable number of failed login attempts from the same IP, further attempts are blocked for a configurable lockout period. Stops dictionary attacks and credential-stuffing bots cold.</li>
<li>⏱ Configurable Lockout — Set exactly how many failed attempts trigger a lockout, and how many minutes the lockout lasts. Default: 5 attempts, 15-minute lockout.</li>
<li>📋 Full Audit Logging — Every blocked login attempt is logged with the IP address, timestamp, and the reason for the block, so you can see exactly what threats your site faces.</li>
</ul>
<h4>👤 MODULE 4: Registration Spam Protection</h4>
Block fake accounts and spam bot registrations before they are ever created in your database.
<ul>
<li>🍯 Registration Honeypot — A hidden field traps bots that auto-fill every registration field.</li>
<li>⏱ Registration Time Check — Blocks registrations submitted impossibly fast or from expired form sessions.</li>
<li>📧 Email Domain Blocking — Block registrations from specific disposable email domains. Subdomain matching included — blocking <code>spammail.com</code> also blocks <code>user@sub.spammail.com</code>.</li>
<li>🔤 Username & Email Keyword Filter — Blocks registrations with prohibited words in the username or email address.</li>
<li>📈 Registration Rate Limiter — Limits the number of registration attempts per IP in a configurable period.</li>
<li>🌐 REST API & XML-RPC Coverage — Protection applies to ALL registration paths: the standard form, the WordPress REST API, and direct <code>wp_insert_user()</code> calls. Fake accounts are blocked before they are ever written to the database, which also prevents WordPress from sending notification emails for blocked registrations.</li>
</ul>
<h4>🤖 MODULE 5: Advanced Bot Protection</h4>
A dedicated bot-detection engine that runs before WordPress even fully loads — blocking malicious traffic at the earliest possible moment.
<ul>
<li>🕵️ Known Bad Bot Blacklist — 30+ built-in user-agent signatures covering scrapers (AhrefsBot, SemrushBot, MJ12bot), vulnerability scanners (Nikto, sqlmap, WPScan, Acunetix, Nessus), DDoS tools (Slowloris, LOIC), AI crawlers, and spam bots. Fully customizable with your own additional signatures.</li>
<li>🚫 Empty User-Agent Blocking — Blocks all requests with no User-Agent header — a near-universal sign of automated attack traffic.</li>
<li>🔍 Fake Googlebot / Bingbot Detection — Real Googlebots come from specific Google-owned IP ranges with verifiable reverse DNS. This module performs a live reverse DNS lookup to verify any request claiming to be Googlebot or Bingbot, and blocks fakes that don’t pass verification. Protects your server resources from being wasted on impersonators.</li>
<li>⚠️ Suspicious URL Pattern Blocking — Blocks probes for sensitive files and attack patterns including:
<ul>
<li><code>/wp-config.php</code>, <code>/.env</code>, <code>/.git/</code>, <code>/.htaccess</code> access attempts</li>
<li>Web shell uploads (<code>shell.php</code>, <code>c99.php</code>, <code>r57.php</code>)</li>
<li>Directory traversal attacks (<code>../../</code>)</li>
<li>SQL injection in URLs (<code>UNION SELECT</code>, <code>DROP TABLE</code>)</li>
<li>XML/XXE injection attempts</li>
<li>phpMyAdmin and database tool probes</li>
<li>WordPress scanner paths (<code>/wp-content/uploads/*.php</code>)</li>
</ul>
</li>
<li>🌊 Request Flood Protection — Sitewide per-IP rate limiting that blocks any IP sending excessive requests within a configurable time window. Stops DDoS and scraping attacks that would otherwise overload your server.</li>
<li>🔒 HTTP Method Filter — Blocks unnecessary and dangerous HTTP methods such as TRACE and CONNECT that are used by certain attack tools.</li>
<li>🛡️ Security Headers — Automatically adds five HTTP security headers to every response:
<ul>
<li><code>X-Content-Type-Options: nosniff</code></li>
<li><code>X-Frame-Options: SAMEORIGIN</code></li>
<li><code>X-XSS-Protection: 1; mode=block</code></li>
<li><code>Referrer-Policy: strict-origin-when-cross-origin</code></li>
<li><code>Permissions-Policy: geolocation=(), microphone=(), camera=()</code></li>
</ul>
</li>
<li>🎭 Hide WordPress Version — Removes the WordPress version number from page source, RSS feeds, script/style URLs, and HTTP headers — making version-specific exploit scanning much harder.</li>
<li>👤 Block Author Enumeration — Blocks the <code>?author=1</code> URL trick that attackers use to discover your WordPress usernames before launching targeted brute-force attacks.</li>
<li>✏️ Custom Bot Signatures & URL Patterns — Add your own custom bot user-agent signatures and URL regex patterns directly from the admin panel.</li>
</ul>
<h4>⚙️ MODULE 6: General WordPress-Wide Protection</h4>
Site-wide hardening that protects your WordPress installation at the infrastructure level.
<ul>
<li>📡 XML-RPC Protection — Fully disable XML-RPC (a common DDoS amplification vector), or choose the surgical option: disable only the pingback methods while leaving the rest of XML-RPC available for legitimate use (e.g. mobile apps).</li>
<li>🔗 REST API Rate Limiting — Rate-limit unauthenticated REST API requests per IP to prevent API abuse by bots and scrapers.</li>
<li>🚫 REST API User Enumeration Block — Automatically blocks unauthenticated access to the <code>/wp/v2/users</code> REST endpoint, which attackers use to harvest all WordPress usernames on your site.</li>
<li>🏓 Trackback & Pingback Spam Blocking — Block all incoming trackback and pingback requests sitewide. Also removes the <code>X-Pingback</code> HTTP header and the pingback URL from your blog info to hide the endpoint from probes.</li>
<li>🔗 Comment Author URL Hold — Automatically sends any comment to moderation when the author’s display name contains a URL — a common spam technique.</li>
</ul>
<h4>📊 Spam Log & Reporting</h4>
<ul>
<li>Full Audit Log — Every blocked request is logged with the IP address, user-agent, submission data, block reason, and timestamp. Available under Anti-Spam Protection → Spam Log.</li>
<li>Filter by Module — Quickly find blocked entries by protection module (honeypot, rate limiter, bot protection, login, registration, etc.).</li>
<li>Automatic Log Cleanup — Set a log retention period in days and old entries are automatically purged. Keep your database clean without manual work.</li>
<li>One-Click Log Clear — Clear all log entries instantly from the admin panel.</li>
</ul>

What data is sent and when? 
When reCAPTCHA is enabled, the visitor’s reCAPTCHA response token and IP address are sent to Google’s servers at the time of a form submission.
No data is sent to Google if the reCAPTCHA module is disabled.

5 Star Plugins (Rob)

Cloud Maestro brings centralized Cloudflare Web Application Firewall (WAF) controls directly into WordPress.
Why would I use a plugin when I can create rules in Cloudflare? 
If you manage multiple Cloudflare-connected sites, Cloud Maestro is a productivity tool that helps oversee several domains from a central dashboard using WordPress. If you only manage one domain in Cloudflare, you wouldn’t benefit from this plugin.
It’s useful for someone managing: 
– Their own sites and client sites 
– Multiple businesses 
– Separate Cloudflare accounts
People like using Cloud Maestro because configuring security rules one domain at a time is inefficient and error-prone. It allows you to configure WAF rules once and deploy them consistently across all domains in your Cloudflare account — instantly.
The free version supports one Cloudflare account with multiple domains.
An optional premium version is available for managing unlimited domains across multiple Cloudflare accounts at once.

<li>Multi-Account Management – Centrally manage unlimited domains across all your Cloudflare accounts</li>
</ul>
<h3>📋 Important Information</h3>
Rule Replacement: This plugin replaces existing custom WAF rules on targeted domains. Make sure to back up any custom rules you want to keep.
Compatibility: Works with Cloudflare Free, Pro, and Business plans. Not compatible with Enterprise plans managed by hosting providers.
Service Monitoring: These rules might challenge some monitoring or uptime services. Check Cloudflare’s Events log if services stop connecting, and add exceptions as needed.
