When to use Website Security Scanner

Website Security Scanner vs related tools

Website Security Scanner vs Header Checker

A header checker focuses mainly on HTTP response headers. Website Security Scanner gives a broader first-pass view by combining HTTPS, redirects, headers, robots.txt, and sitemap checks. If you want a wider launch or audit snapshot, the scanner is the better first step.

Website Security Scanner vs SSL Checker

SSL Checker is more focused on certificate and HTTPS details. Website Security Scanner looks at broader visible website signals around security and technical setup. If your question is specifically about certificate quality, use the SSL tool. If you want a wider website-level overview, start with this scanner.

Helpful next steps

If the issue looks certificate-related, continue with SSL Checker. If the problem is mainly redirect behavior, use Redirect Checker. If you want to inspect header coverage more closely, open HTTP Header Checker.

Examples

Example

Input

https://example.com

Output

HTTPS: OK
Redirect: OK
Headers: Good
Robots: Found
Sitemap: Found

Useful for a quick launch or health check when the site already follows basic best practices.

Example

Input

https://mysite.com

Output

HTTPS: OK
Redirect: OK
Headers: Missing CSP
Robots: Found
Sitemap: Found

Helpful when a site is live but still missing one or more important security-related headers.

Example

Input

http://example.com

Output

HTTPS: Missing
Redirect: Not forced
Headers: Weak
Robots: Found
Sitemap: Not found

Useful for spotting sites that still allow insecure access or incomplete redirect behavior.

Example

HTTPS: OK
Redirect: OK
Headers: Weak
Robots: Found
Sitemap: Missing

Helpful when reviewing both security basics and crawl-related technical signals together.

Example

Input

http://staging.example

Output

HTTPS: Missing
Redirect: Missing
Headers: Weak
Robots: Not found
Sitemap: Not found

Useful when auditing unfinished deployments, staging environments, or neglected client sites.

Example

Common errors

Invalid URL format

Fix: Enter a full URL and include http:// or https:// before the domain.

Website is unreachable or blocks the request

Fix: Check that the domain is live and accessible, then try again.

HTTPS is enabled but redirects are inconsistent

Fix: Make sure HTTP requests are redirected cleanly to the preferred HTTPS version.

Headers are present but incomplete

Fix: Review which security headers are missing and add them one by one.

Robots or sitemap results are missing

Fix: Check whether robots.txt and sitemap.xml exist at the expected paths and are publicly accessible.

FAQ

What does this website security scanner check?

It checks basic website security and technical signals such as HTTPS, redirects, common security headers, robots.txt, and sitemap availability.

Is this a full vulnerability scanner?

No. It is a lightweight configuration and signal checker, not a deep vulnerability assessment platform.

Can this tool detect missing security headers?

Yes. It helps identify whether key security-related headers appear to be missing or weak.

Why does the tool check robots.txt and sitemap.xml too?

These files are not security controls, but they are useful technical website signals that often matter during launch reviews and technical audits.

Can I use this tool for SEO audits?

Yes. It is useful for technical SEO checks because HTTPS, redirects, robots.txt, and sitemap availability often overlap with audit workflows.

Why does my site show weak headers?

That usually means one or more important headers are missing, incomplete, or not configured consistently.

Does this scanner check malware or deep vulnerabilities?

No. It focuses on common visible website configuration checks rather than deep exploit or malware scanning.

Can I scan client websites with it?

Yes. It works well for quick reviews and first-pass checks before deeper technical analysis.

What should I do after finding issues?

Review each result, fix the configuration on the site or server side, and run the scan again to confirm the improvement.

What is the difference between this tool and a header checker?

A header checker focuses mainly on HTTP headers, while this scanner combines headers with HTTPS, redirect, robots.txt, and sitemap checks in one place.
