About this plugin
Shakvaro Shield is a comprehensive WordPress security plugin designed to protect your site against the most common and advanced threats. It combines a Web Application Firewall (WAF), brute force protection, Two-Factor Authentication, file integrity monitoring, and a full suite of hardening checks into a single, well-organized package. Whether you run a personal blog or a high-traffic business site, Shakvaro Shield gives you enterprise-grade security without the complexity.
At the heart of Shakvaro Shield is a Web Application Firewall that loads via an auto-installed mu-plugin, allowing it to inspect and block malicious requests before WordPress and other plugins even begin to load. The firewall ships with six built-in rules covering SQL injection, cross-site scripting (XSS), directory traversal, file inclusion, and other common attack vectors.
Alongside the WAF, Shakvaro Shield performs 15 security hardening checks and calculates an A-F health score so you can see your site’s security posture at a glance. Each check includes a one-click fix or clear remediation instructions, making it easy to bring your score up to an A.
Login security is where Shakvaro Shield truly shines. Brute force protection uses progressive lockouts that increase in duration with each failed attempt, effectively neutralizing automated attacks. Two-Factor Authentication supports any TOTP-compatible authenticator app and generates single-use backup codes so users are never locked out.
php entirely, enforce password strength policies, and add CAPTCHA verification using reCAPTCHA v3, Cloudflare Turnstile, or a lightweight math-based fallback that requires no external service.
Shakvaro Shield is built for performance. The entire plugin is under 1 MB, uses PSR-4 autoloading so classes are only loaded when needed, and adds zero JavaScript or CSS to your site’s frontend. org checksums, alerting you to unauthorized changes.
Every security-relevant action is recorded in a searchable activity log with over 30 event types, and email notifications use intelligent throttling and optional daily digests so you stay informed without inbox overload. A guided setup wizard walks you through initial configuration in under two minutes.
