Security Headers Checker or security scanning?
The checker reads one thing closely on any site: the headers a browser enforces. The scan covers the whole public surface of a site you own, and ends in a report.
Side by side.
| What is compared | Security Headers Checker | Security scanning |
|---|---|---|
| Which sites | Any public website | A site you have verified you own |
| Account | 3 checks a day without one; 60 an hour with a free account | Pro or Business |
| Looks at | Security headers and cookies, read the way a browser enforces them | 30+ checks: headers, HTTPS enforcement, exposed files, technology disclosure, cookies, email and DNS records |
| Grade | A+ to F, from two scores: coverage and effectiveness | A+ to F, from a score out of 100: each failing check takes off points by its severity |
| Fixes | Written for 32 platforms | Every finding explained, with what to do about it |
| What you keep | The result on screen; with a free account, a share link, a PDF and 30 days of history | A branded PDF report with an AI summary |

Choose the Security Headers Checker when
- You want a quick answer about any site's headers.
