All Free Features 
The Sentinel Headers Unlimited version includes all the free features.
Sentinel Headers Unlimited Extension is based on OWASP CSRF to protect your wordpress site. Using OWASP CSRF, once the plugin is installed, it will provide full CSRF mitigation without having to call a method to use nonce on the output. The site will be secure despite having other vulnerable plugins (CSRF).
HTTP security headers are a critical part of your website’s security. After automatic implementation with Sentinel Headers Unlimited Extension , they protect you from the most notorious types of attacks your site might encounter. These headers protect against XSS, code injection, clickjacking, etc.
We have implemented FLoC (Federated Learning of Cohorts), using best practices. First, using Sentinel Headers Unlimited Extension prevents the browser from including your site in the “cohort calculation” on FLoC (Federated Learning of Cohorts). This means that nothing can call document.interestCohort() to get the FLoC ID of the currently used client. Obviously, this does nothing outside of your currently visited site and does not “disable” FLoC on the client beyond that scope.
Even though FLoC is still fairly new and not yet widely supported, as programmers we think that privacy protection elements are important, so we choose to give you the feature of being opt out of FLoC! We’ve created a special “automatic blocking of FLoC” feature, trying to always offer the best tool with privacy protection and cyber security as main targets and focus.
Analyze your site before and after using *Sentinel Headers Unlimited Extension * security headers are self-configured according to HTTP Security Headers and HTTP Strict Transport Security / HSTS best practices.

<h3>0.0.03</h3>
We don’t want to tell you what to do, but here’s the thing: I went over the version of the Sentinel Headers Unlimited Extension 2022 plugin and started with a really crazy, spacey update; if you updated the plugin last time, you saw that when I propose to do it, I don’t just say it. Well, with this version 1.0.03 I have added, corrected, rewritten and tested a lot of code (improving and implementing some really crazy programmer stuff) and everything works like a charm. Do we agree? Tap “update” and I’ll give you the best, fastest, most awesome plugin around with the best updates in the world. Now I am already planning the next updates 😀 I hope you pigeonhole the new features and have fun.
