HSTS preload checker
My HSTS Preload Checker is a tool that helps you check if your website meets the requirements for HSTS (HTTP Strict Transport Security) preloading. By enabling HSTS preloading, you indicate to browsers that your site should always load over HTTPS, which improves the security of your website.
What is HSTS Preloading?
HSTS Preloading is a mechanism by which a Web site is included in a preloading list used by browsers to force Web sites to always load over HTTPS, even on the first connection. Adding your site to the preloading list improves security and protects your site from attacks such as man-in-the-middle attacks.
Why use an HSTS Preload Checker?
- Make sure your website is set up correctly to enforce HTTPS for all visitors from the first visit.
- Avoid configuration errors that could prevent your website from being added to the HSTS preload list.
- Ensure your website meets the strict requirements set by browsers for HSTS preloading.
- Immediately verify that your domain is correctly configured and ready for preloading.
What does this tool check for?
- HSTS header: Checks if your site contains the correct HSTS header and it is set correctly (including “preload” and “includeSubDomains” parameters).
- Max-age parameter: Verifies that the
max-age-value is set to at least 1 year (31536000 seconds). - HTTPS implementation: Verifies that your site loads completely over HTTPS with no redirects or errors.
- Preload status: Looks at whether your domain is already in the HSTS preload list or ready to be added.
How does the HSTS Preload Checker work?
- Enter your domain: Type or paste your domain name that you want to check for HSTS preload compatibility.
- Automatic check: The tool checks if your website meets the requirements for HSTS preloading.
- Receive Results: Get a detailed report on your domain’s HSTS configuration, including recommendations for adjustments.
With my HSTS Preload Checker, you can easily check if your website meets the requirements for inclusion in the HSTS preload list. By ensuring that your site meets the preloading criteria, you’ll better protect your visitors from security risks and improve the reliability of your website.
