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.

This plugin is updated periodically, our limited support is free, we are available for your feedback (bugs, compatibility issues or recommendations for next updates). We are usually fast :-D.
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.

How do I get an A+ / A grade for security headers with the plugin?
To earn an A+ / A grade, your site must issue all HTTP response headers that we check. This indicates a high level of commitment to improving the security of your visitors. Your site must also support HTTPS with a valid SSL certificate. This ensures that your visitors’ data is protected from attackers.
What are the recommended headers?
Web security headers are important for protecting sensitive data and user privacy. Setting security headers correctly can help prevent man-in-the-middle attacks and ensure data privacy.
Recommended security headers include:
Make sure to check your headers before and after plugin installation. https://securityheaders.com/
Can the Sentinel Headers Unlimited Extension create slowdowns?
The Sentinel Headers Unlimited Extension is designed to be fast, secure, and not affect the SEO or speed of your website.
What is HSTS (Strict Transport Security)?
HSTS is a security measure that tells web browsers to only connect to websites using HTTPS, instead of HTTP. This ensures that all communication between the browser and the website is encrypted and secure. HSTS is important because it helps protect against man-in-the-middle attacks and other types of attacks that could compromise user data.
Check before and after using Preload HSTS
Preload HSTS is a great tool that can help improve your website’s security. However, it is important to check your website before and after using Preload HSTS to make sure that everything is working as expected. If you’re not familiar with Preload HSTS, it’s a tool that allows you to tell browsers to only connect to your site using HTTPS. This means that if someone tries to access your site using HTTP, they’ll be automatically redirected to the HTTPS version. Google officially compiles this list and it is used by Chrome, Firefox, Opera, Safari, IE11 and Edge. You can forward your site to the official HSTS preload directory. (‘https://hstspreload.org/’)
how to use HTTP Strict Transport Security (HSTS)
If you want to use Preload HSTS for your site, there are a few requirements before you can activate it.
- Have a valid SSL certificate. You can’t do any of this anyway without it.
- You must redirect all HTTP traffic to HTTPS (recommended via permanent 301 redirects). This means that your site should be HTTPS only.
- You need to serve all subdomains in HTTPS as well. If you have subdomains, you will need an SSL certificate.
The HSTS header on your base domain (for example: example.com) is already configured you just need to activate the plug-in.
If you want to check the HSTS status of your site, you can do so here: https://hstspreload.org/

Disable FLoC, Google’s advertising technology
FLoC is a mega tracker that monitors user activity on all sites, stores the information in the browser, and then uses machine learning to place users into cohorts with similar interests. This way, advertisers can target groups of people with similar interests. Plus, according to Google’s own testing, FLoC achieves at least 95% more conversions than cookies.
Who is disabling FLoC by Google?
Scott Helme reported that as of May 3, already 967 of the first 1 million domains had disabled FLoC’s interest-cohort in their Permissions-Policy header. That list included some big sites like The Guardian and IKEA.
How to use and configure Report URI service with the plugin?
Setting up Report URI, we have implemented the service to find out what is happening on your site.
To use Report Uri you just need to register on the website: report-uri.com, once registered the account (verified the confirmation email and activated the two factors) you can go from the side menu and click the “SETUP”, at this point you are the following procedure.
You can customize the custom domain name for Report URI directly in the plugin section “Sentinel”.
- once you enter the “Setup” page, in the custom subdomain box enter the domain name (example: yourdomain.com will be yourdomain.report-uri.com) and save;
- once inserted the domain name in the box “Your report-uri value” select at the item “Policy Disposition” Report-Only.
- now from the menu click the item “CSP” and “Reports” here you will see if there are value that are reported on the website.
- once you enter the “Filters” page, in the Sites for which to collect reports box enter your domain name (example: yourdomain.com) and save;
We have used Uri reports because it allows 10’000 monthly reports and it is a free service but above all it is professional.
Important: if you use some external services that are not present on our CSP list please write us an email at support@tentacleplugins[dot]com
