How to Check a Website's Headers and Safety Score

Network & Domain · Step-by-step guide · 5 steps · 2 min read

When you open a website, it sends hidden notes called headers. Some of them keep visitors safe. This tool shows the headers and scores the safety ones.

Open the HTTP Headers Checker

In the pictures, orange letters like A show where to look. Each step tells you its letter.

Step 1: Type the web address

Type a full address like https://example.com into URL to check. See A in the picture.

Step 2: Choose the method

HEAD is quick. Use GET if a site acts differently with HEAD. Keep Follow redirects on to see every jump. See B in the picture.

Step 3: Press Check Headers

The result loads in a moment. See C in the picture.

Step 4: Read the safety score

The score card grades the safety headers, like HSTS and CSP. See D in the picture.

Step 5: Look at each item

Each header shows if it is there and what it does. So you know what to fix. The full list is below. See E in the picture.

Tips and questions

What is HSTS?

It tells browsers to always use the safe HTTPS version of your site.

What is CSP?

It tells the browser which scripts and images are allowed. It is a strong guard against harmful code.

Why is the result different from my browser?

The check runs on a server, not in your browser. Logins and location can change what a site sends.

Privacy

The address you type goes to the Wivrix server, which fetches the headers. We do not keep results.
