WordSentinel

The WordSentinel plugin by Nexsol Technologies Sàrl enhances your WordPress website’s security by automatically applying and managing HTTP security headers — including Content Security Policy (CSP) — while providing live security analysis powered by Mozilla Observatory.

Unlike simple header managers, WordSentinel actively helps you understand, measure, and improve your site’s protection.
It provides clear dashboards, actionable insights, and real-time grading so you can reinforce your headers with confidence — no deep technical knowledge required.

What WordSentinel Does

WordSentinel helps protect your WordPress website against common web vulnerabilities such as:
– Cross-Site Scripting (XSS)
– Clickjacking attacks
– Content injection and mixed content issues
– Insecure resource loading (scripts, iframes, styles)

It does so by implementing a complete and configurable set of browser-level security headers, giving you granular control over each directive.

In addition, it connects securely to Mozilla Observatory to scan your site and assign a security grade (A+ to F), helping you benchmark your configuration and understand what needs improvement.
