SecurityHeaders.com Alternative: Comprehensive Security Header Scanner
SecurityHeaders.com by Scott Helme is the most recognized HTTP security header scanner online. It provides a quick letter grade for any URL. But if you need deeper analysis, fix recommendations, or want to check additional headers beyond the standard six, Email Armory's Security Headers Analyzer is a strong alternative.
Why Look for a SecurityHeaders.com Alternative?
SecurityHeaders.com does one thing well: it scans HTTP response headers and assigns a grade. However, it checks only 6 headers, does not explain how to fix issues, and offers no additional tools for broader security analysis. Developers and security teams often need more context — what exactly is wrong, how to fix it, and what other security aspects to check alongside headers.

Where SecurityHeaders.com Still Excels
SecurityHeaders.com deserves credit for pioneering HTTP security header awareness. Its simple letter-grade system (A+ through F) is instantly recognizable and widely referenced in security audits. The site loads extremely fast, and Scott Helme's blog provides excellent educational content about each header. For a quick, no-frills grade check, it remains a clean and reliable tool.
