Website Security Scanner

Inspect HTTPS, TLS certificates, response headers, cookies, redirects, and common website security configuration issues.

Server-side scanTLS inspectionSecurity headers

Scan a public website

Only public websites using standard HTTP or HTTPS ports can be scanned.

External assessment

Review the security controls exposed by a public website

This scanner evaluates browser-visible HTTPS and HTTP security configuration without attempting to exploit vulnerabilities or modify the target system.

Configuration review

Review TLS configuration, certificate chains, redirects, security headers, cookies, and browser protection mechanisms to identify common deployment mistakes and missing hardening controls.

Not a penetration test

Passing configuration checks does not guarantee that an application is secure. Business logic flaws, authentication weaknesses, insecure APIs, and software vulnerabilities require additional security testing.

Guide

About Website Security Scanner

A public website exposes TLS, redirect, header, and cookie configuration to every visitor.

This scanner performs a limited external review of those browser-visible controls without attempting exploitation.

A clean configuration report does not replace secure development, code review, dependency management, or penetration testing.

What the scanner checks

The scan focuses on externally visible web security configuration.

  • HTTPS and redirects
  • TLS certificate details
  • Security headers
  • Cookie attributes
  • Information disclosure
  • Common configuration findings

Security headers

Headers can reduce clickjacking, content injection, MIME confusion, excessive permissions, and privacy leakage.

TLS and certificates

Certificate validity, hostname coverage, chain quality, and HTTPS behavior affect connection security and reliability.

Assessment limitations

The scan does not test authentication, authorization, business logic, source code, dependencies, or internal APIs.

FAQ

Frequently asked questions

Does the scanner exploit the website?

No. It performs a limited configuration review.

What does it check?

HTTPS, certificates, redirects, response headers, cookies, and common public configuration issues.

Does passing mean the site is secure?

No. Many important application risks are outside the scope of this scan.

Why are security headers useful?

They instruct browsers to apply protections and restrictions around content and transport.

Can results differ over time?

Yes. DNS, certificates, CDN behavior, redirects, and deployment configuration can change.

Does the scan contact the target?

Yes. The server performs network requests to inspect the public website.
