Security score

Risk levelMedium

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

The domain recaptcha.net is owned and operated by Google LLC, providing the reCAPTCHA service which is widely used for bot detection and spam prevention on websites. However, the current content at the provided URL is a 404 error page indicating the requested resource is not found. This limits the ability to analyze the website's content, policies, and security posture directly from this page. The domain registration data confirms legitimacy and consistency with Google's ownership and long-standing presence since 2007. The technical infrastructure is hosted by Google with Google name servers, but no additional technical or security details are available from the page content. Security posture cannot be fully assessed due to lack of accessible content and security headers. Overall, the site is safe with no adult or questionable content, but the lack of accessible content results in a very low AI score and limited insights.

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

reCAPTCHA is a key Google service in the technology sector, providing CAPTCHA and bot mitigation solutions to website owners and developers globally. The business model revolves around offering security tools integrated into websites to prevent automated abuse. The domain's registration and hosting by Google reinforce its market position as a leading provider in this niche. However, the analyzed URL does not provide direct business or contact information, limiting visibility into operational details or partnerships. The service targets a broad audience of web developers and enterprises needing security against bots and spam. The domain age and registrar data support a mature and credible business presence.

Security posture

Due to the 404 error page and minimal content, no security headers or policies are detectable on this URL. The domain is hosted by Google, which typically enforces strong security practices, but no direct evidence is available here. No incident response contacts, vulnerability disclosures, or security frameworks are presented on the page. The lack of HTTPS or security header information in the provided data limits the security score. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture assessment is limited and scores low due to lack of accessible security information.

Recommendations

  1. Ensure the main website or service pages are accessible and not returning 404 errors to provide users with relevant content and policies.
  2. Publish clear privacy, cookie, and terms of service policies accessible from the domain to improve compliance and user trust.
  3. Implement and expose security headers and incident response contact information on the website to enhance security posture and transparency.
  4. Add contact information including emails and phone numbers for support and security incident reporting.
  5. Regularly audit website content and links to prevent broken pages and improve user experience.

Technical notes

Notes

The website content is minimal and consists solely of a 404 error page with basic HTML and inline CSS referencing Google-hosted images. No JavaScript libraries, frameworks, or CMS are detected. The domain is hosted on Google infrastructure with Google name servers, indicating a robust hosting environment. However, the lack of accessible content and metadata limits SEO, accessibility, and performance assessments. No analytics or tracking scripts are present on this page. The technical implementation appears minimal and placeholder in nature, likely indicating a misconfigured or missing resource rather than a fully developed site.
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.
