HTTP Security Headers Checker
Review security-related HTTP response headers from a public URL.
The Elevoire inspection service retrieves only the supplied public website and applies strict network and response limits.
Check live HTTP security headers
The report highlights commonly useful browser security headers and presents returned values for review.
Header presence is not proof that a website is secure, and an inappropriate policy can be ineffective or break legitimate behavior.
How to use the HTTP Security Headers Checker
- Provide the complete value or source material you want to inspect.
- Run the check and review each result or warning.
- Correct the original source and repeat the check before using it.
Practical example
Review the result against the needs of the specific website or account instead of treating a generated value as a complete security review.
What this tool cannot guarantee
A focused browser tool cannot replace layered security controls, current software, monitoring or a professional assessment.
