Security Plugin Development

Custom-Built Plugins to Protect Your System at Its Core

Overview

Your WordPress site is only as secure as its weakest plugin. While many off-the-shelf security plugins offer basic protection, they often come bloated with unnecessary features, slow down your site, or expose your system to new vulnerabilities.

At [Your Company Name], we design and develop bespoke WordPress security plugins tailored specifically to your site’s architecture and threat landscape. From hardening the admin interface to detecting zero-day threats, our plugins deliver deep, surgical protection where generic solutions fall short.

✅ Why Choose a Custom Security Plugin?

• No Bloatware: Only the features you need. No unnecessary code that could slow your site or become an attack vector.

• Built for Your Stack: Our plugins are optimized for your server environment (e.g., NGINX, Apache), CMS configuration, and existing plugin ecosystem.

• Zero-Day Focus: We integrate heuristics and anomaly detection to catch suspicious behavior even before signatures are updated.

• DevSecOps Friendly: CI/CD compatible with built-in logging, alerting, and API integrations for security teams.

🛡️ Core Features

1. Authentication & Access Control Hardening

• Two-Factor Authentication (2FA) via TOTP (Google Authenticator, Authy)

• IP-based login whitelisting/blacklisting

• Automatic admin panel obfuscation (/wp-admin stealth redirect)

• CAPTCHA + honeypot integration for brute-force mitigation

2. File Integrity Monitoring

• Real-time hashing of core WordPress, theme, and plugin files (SHA-256)

• Comparison against WordPress.org checksums API

• Custom alert thresholds (e.g., modified functions.php)

• CLI interface to verify hashes for CI pipelines

3. Firewall & Request Filtering

• Custom Web Application Firewall (WAF) based on OWASP CRS principles

• Rate-limiting for high-frequency endpoints (e.g., /xmlrpc.php)

• SQLi, XSS, and LFI pattern detection using regex + token parsing

• JSON-based ruleset configuration (YAML support optional)

4. Audit Logging & Alerting

• Full audit trail of user logins, file changes, settings updates

• Syslog export support for integration with SIEM tools (e.g., Splunk, Graylog)

• Email and webhook notifications for high-risk events

• Role-based logging filters (e.g., log only admin-level actions)

5. Security Headers & SSL Enforcement

• Automatic injection of security headers:

  • Strict-Transport-Security

  • X-Content-Type-Options

  • X-Frame-Options

  • Content-Security-Policy (CSP with nonce-based rules)

• Force HTTPS with HSTS preload option

• HTTP Public Key Pinning (HPKP) [optional, legacy]

6. Zero-Day Exploit Shield

• Behavior-based detection engine using:

  • Function call tracing (eval, system, exec)

  • File upload fingerprinting

  • Unexpected HTTP verb monitoring (e.g., DELETE, PUT)

• Sandboxed execution logs for suspicious PHP calls

• ML-based anomaly scoring (optional add-on)
