Banana Defender – GDPR-Compliant Firewall, Scanner & Virtual Patching for WordPress

Description

Most WordPress security plugins are built for the US market, phone home to external clouds, and drop tracking cookies on your visitors. Banana Defender does none of that.

Install the plugin. Launch the wizard. Done in 2 minutes. Your firewall, malware scanner, login protection, and virtual patching are configured — no cybersecurity degree required. Easy for beginners, fully flexible for pros.

Banana Defender runs entirely on your server. No data leaves your site, no cloud dependency, no AV contract needed. 33,000+ known vulnerabilities are blocked automatically through Virtual Patching — for free. GDPR-compliant and cookie-free from the moment you activate it.

Built in Germany by flexxDEV. Because your website’s security shouldn’t depend on a data center in Virginia.

Why Banana Defender?

• Zero Cloud, Zero Tracking, Zero Cookies — Your data stays on your server. Period. No external connections, no visitor tracking, no cookie banners needed.

• 2-Minute Setup Wizard — Firewall, scanner, login protection — configured, not complicated. Works for site owners and developers alike.

• Made in Germany — Developed by flexxDEV. German engineering for WordPress security.

External Services

This plugin optionally connects to the following external services:

Freemius

When activated, Banana Defender uses the Freemius SDK for license management and optional usage analytics. No data is transmitted without explicit user consent — an opt-in screen is shown after plugin activation.

Vulnerability Database

Banana Defender downloads vulnerability data from the flexxDEV update server to power the virtual patching engine. This connection transmits only the plugin version and WordPress version. No personal or site-identifying data is sent.

• Server: flexx-hosting.de
• flexxDEV Privacy Policy

WordPress.org API

The File Integrity Monitoring feature retrieves checksums from api.wordpress.org to verify WordPress core files. This transmits your WordPress version and locale. No personal data is sent.

• WordPress.org Privacy Policy

Advanced Configuration

WP-CLI Commands

Banana Defender registers WP-CLI commands for server-side management. Useful for locked-out situations, automated deployments, and headless administration.

Command
Description

wp banana-defender status
Show plugin version and module status (enabled/disabled)

wp banana-defender login-url
Display the current custom login URL

wp banana-defender reset-login-url
Disable the custom login URL and restore wp-login.php access

Example — recover from a forgotten custom login URL:

wp banana-defender reset-login-url

wp-config.php Constants

You can override certain Banana Defender behaviors by defining constants in your wp-config.php. Add them before the /* That's all, stop editing! */ line.

Constant
Value
Effect

BANADE_DISABLE_LOGIN_URL
true
Disables the custom login URL feature entirely. wp-login.php becomes accessible again without changing any plugin settings. Use this as an emergency recovery when you forgot your custom login URL and cannot access WP-CLI.

Example — restore login access via wp-config.php:

define( 'BANADE_DISABLE_LOGIN_URL', true );

After regaining access, disable the custom login URL in the plugin settings and remove the constant from wp-config.php.
