– Text Recognition: Warped text characters requiring human recognition
Both are effective against automated bots while remaining accessible to humans.

– Multiple provider support with automatic fallback 
– Self-hosted option for complete independence 
– Advanced rate limiting built-in 
– Modern, user-friendly admin interface 
– Regular updates and active development 
– Clean, well-documented code
<h3>Privacy & Data Collection</h3>
What Data Does This Plugin Collect?
SecureGate Captcha Lite is designed with privacy as a core principle:
Stored Locally (in your WordPress database as transients): 
* Anonymized IP addresses (last octet removed) 
* Timestamp of verification attempts 
* Success/failure status of CAPTCHA verifications 
* Failed attempt counters for rate limiting
NOT Stored: 
* User emails or usernames 
* Personal identifying information 
* Browser fingerprints 
* Tracking cookies (plugin-side) 
* Permanent user profiles
External Service Data: 
When Cloudflare Turnstile is enabled, user browser data is sent to Cloudflare for bot detection. Please review <a href="https://www.cloudflare.com/privacypolicy/" rel="nofollow ugc">Cloudflare’s Privacy Policy</a> for details.
When using the Built-in CAPTCHA, NO external services are contacted.
Data Retention: 
All logs are stored as WordPress transients and automatically deleted after 7 days. Administrators can disable logging entirely in settings.
Right to Erasure: 
No personal data is collected that would require manual erasure requests under GDPR.

Guardify is a powerful WordPress firewall plugin designed to protect your website from a wide range of threats, including brute force attacks, SQL injections, malicious bots, and unauthorized access attempts. With an intuitive dashboard, detailed statistics, and advanced settings, Guardify empowers you to secure your site effortlessly.
<h3>🔐 Key Features:</h3>
<ul>
<li>
Advanced Web Application Firewall (WAF) 
Intercepts and filters all incoming traffic before it reaches WordPress. Blocks SQL injection, XSS, RFI, LFI, and other attack vectors.
</li>
<li>
Brute Force Attack Protection 
Blocks repeated login attempts by limiting login frequency and analyzing IP reputation.
</li>
<li>
2-Factor Authentication (2FA) 
Adds an extra layer of login security for admin users, using time-based one-time passwords (TOTP).
</li>
<li>
Real-Time Activity Logs 
Track login attempts, blocked IPs, suspicious requests, and system actions with detailed logs. View statistics by day, week, or month.
</li>
<li>
Custom IP Whitelisting & Blacklisting 
Control access to your site by adding IPs or IP ranges to allow or deny lists. Includes temporary blocking for failed login attempts.
</li>
<li>
GeoIP Blocking 
Block or allow access from specific countries using the MaxMind GeoIP2 database integration.
</li>
<li>
Bot Access Control 
Detect and manage access from known bots, scrapers, and fake crawlers. Option to block non-human traffic.
</li>
<li>
Anti-PHP Injection & File Access Blocking 
Prevents direct access to PHP files in sensitive directories such as <code>/wp-includes/</code> and <code>/wp-content/uploads/</code>.
</li>
<li>
Block Plugin and Theme Installation 
Restrict installation of new plugins and themes via the WordPress dashboard — even by administrators. This helps prevent unauthorized or accidental installation of insecure components. Manual installation via FTP remains possible.
</li>
<li>
Block Theme Editor 
Disable access to the Theme Editor (<code>/wp-admin/theme-editor.php</code>) to prevent direct file editing. This minimizes the risk of malicious code injection or unintentional file corruption.
</li>
<li>
Forbidden Comment Words Filter 
Automatically mark comments as spam if they contain forbidden words or patterns (e.g., <code>http</code>, <code>viagra</code>, <code>casino</code>, <code>porn</code>). Helps drastically reduce comment spam by detecting common keywords and links.
</li>
<li>
Auto Block IPs in .htaccess 
When enabled, IPs that exceed the rate limit are automatically added to the <code>.htaccess</code> file for permanent blocking. This server-level block prevents any further requests. Use with care, as shared or corporate IPs may be affected.
</li>
<li>
Email Notifications 
Stay informed with email alerts about critical security events, such as admin login attempts or IP bans.
</li>
<li>
Customizable Firewall Rules 
Advanced users can fine-tune rules with regex filters, HTTP method checks, user-agent filters, and more.

<li>
User-Friendly Admin Interface 
Guardify features a modern and intuitive UI built using native WordPress design language.
</li>
<li>
Clean Uninstall 
Automatically cleans up all data, logs, and settings when uninstalled—leaving your database clean.
