LIVE HTTP SECURITY DIAGNOSTICS

Does the visitor’s browser receive
real protection instructions?

Inspect HTTPS, TLS, and the security headers your website actually sends. We analyze the values and show where protection exists and where configuration gaps remain.

Inspect the public response

One URL. Multiple protection layers.

Enter the URL exactly as a visitor opens it. We follow safe redirects, analyze the final response, and test the HTTP-to-HTTPS transition.

The URL is sent to our server for a public request only. We do not access administration areas, private pages, or internal network addresses.

What do we inspect?

Security is more than a green lock.

HTTPS protects transport; response headers tell the browser how to handle content, frames, capabilities, and referrer data.
01

Transport and certificate

TLS validity, hostname match, certificate expiry, and enforced HTTP-to-HTTPS redirection.

02

Content policy

We analyze CSP and flag broad values such as wildcards, unsafe-inline, and unsafe-eval instead of merely checking that a header exists.

03

Browser behavior

HSTS, nosniff, frame embedding protection, referrer policy, and browser feature permissions.

04

Cookies and information exposure

We review Secure, HttpOnly, and SameSite on visible cookies and flag unnecessary technical disclosure.

Scope of the result

Configuration diagnostics—not a penetration test.

The tool reads what a website sends to an ordinary visitor. It does not bypass authentication, scan application vulnerabilities, or send attack payloads. A missing header does not prove compromise, and complete headers do not prove the system is vulnerability-free.

Practical value: Understand the current state, prioritize improvements, and give developers or server administrators actionable detail.

Quick questions

Before changing configuration.

Should every header be added to every website?

No. Headers such as COOP and COEP support specific capabilities and can break external integrations when imposed blindly. The report distinguishes essentials from contextual improvements.

Why is having CSP not enough?

The policy may be overly broad or allow unsafe-inline, unsafe-eval, or unrestricted sources. We analyze the value rather than passing it because the header name exists.

Is SSL expiry the only certificate concern?

No. The certificate must be within its validity period, match the hostname, and present a trusted chain. The tool reports the available evidence.

Is this a substitute for a security review?

No. It is a focused review of HTTPS and public response headers, not a code review, internal configuration audit, access review, or penetration test.
