NinjaFirewall: Advanced Protection for WordPress Sites

🔹 Introduction

When it comes to defending your WordPress site against brute-force attacks, backdoors, and obfuscated payloads, NinjaFirewall (WP Edition) stands out as a true Web Application Firewall (WAF). Unlike typical plugins, it sits in front of WordPress—intercepting threats before they even reach your core files.

🔍 What Makes NinjaFirewall Unique?

✅ 1. Pre-WordPress Filtering

• NinjaFirewall hooks into HTTP requests before WordPress loads.
• It scans, sanitizes, and blocks malicious payloads—including encoded shell scripts and backdoors.

✅ 2. Sensei Filtering Engine

• Detects evasion techniques like obfuscated SQL injections, XSS, and RCE attempts.
• Normalizes and transforms incoming data to catch threats that bypass conventional firewalls.

✅ 3. Real-Time File Guard

• Alerts you instantly when a PHP file is modified or created.
• If a hacker uploads a shell or injects a backdoor, NinjaFirewall flags it before execution.

✅ 4. Brute-Force Protection

• Blocks login attempts at wp-login.php and xmlrpc.php before WordPress even sees them.
• Supports server-level logging for integration with Fail2Ban.

✅ 5. Header & Cookie Hardening

• Secures outgoing HTTP headers and cookies to prevent leakage or manipulation.
• Adds a final layer of defense before the response reaches the browser.

🧠 Why It’s Ideal for Forensic-Grade Defense

• Works on Unix-like OS only (Linux, BSD)—perfect for your bare-metal doctrine.
• Compatible with PHP 7.1+ and MySQLi, aligning with your current stack.
• Protects non-WordPress scripts too—great for hybrid setups or CLI tools.
