0–100, higher is better. How it is calculated

The domain recaptcha.net is registered to MarkMonitor Inc., a reputable registrar commonly used by large corporations including Google. The domain has been active since 2007 and uses Google name servers, indicating it is likely owned and operated by Google or its affiliates. However, the website content at the root URL is a standard 404 error page indicating the requested resource is not found. There are no privacy policies, cookie policies, terms of service, contact information, or any business-related content available on this page. Technically, the site is hosted on Google's infrastructure but lacks any detectable technologies or scripts due to the minimal error page content. Security posture cannot be fully assessed due to lack of content and headers. No WAF or security challenge was detected, but the site is effectively inaccessible for meaningful analysis due to the 404 error. The site contains no adult or questionable content and is safe for general audiences.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

7 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Given the domain and registrar information, recaptcha.net is associated with Google's reCAPTCHA service, a widely used anti-bot and security service on the internet. The domain's long registration history and use of Google name servers support its legitimacy. However, the lack of accessible content on the root URL suggests this domain is not intended for direct user interaction or public-facing content but rather for backend or service use. There are no visible business details, contact points, or marketing information on the page analyzed. The domain likely serves a technical or service role within Google's ecosystem rather than a standalone business website.

Security posture

The security posture assessment is limited due to the absence of content and security headers in the provided HTML. The domain uses Google name servers and is registered with a trusted registrar, which are positive indicators. DNSSEC is not enabled, which is a minor security gap. No security policies, incident response contacts, or vulnerability disclosures are published on the site. The lack of HTTPS information and security headers in the data prevents a full security evaluation. Overall, the domain appears legitimate but the website itself does not provide security transparency or user-facing security features.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish privacy and cookie policies on accessible URLs to improve compliance and user trust.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve security posture.
  4. Provide clear contact and incident response information to support security transparency.
  5. Ensure the website content is accessible and does not return 404 errors for intended public URLs.

Technical notes

Notes

The website content is minimal and consists solely of a 404 error page with no scripts, forms, or metadata. The domain uses Google name servers and is registered with MarkMonitor Inc., indicating hosting on Google's infrastructure. No CMS or frameworks are detected. The site appears to have basic mobile optimization due to responsive meta viewport tag but lacks SEO optimization and accessibility features. Performance and technical stack cannot be fully assessed due to lack of content. The domain is likely used for backend service purposes rather than as a public-facing website.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
