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

5 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 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Google operates g.co as a utility service to provide trusted short URLs for its vast ecosystem of products and services. This supports Google's broader business model of delivering technology services and advertising solutions. The domain's long history and ownership by Google LLC reinforce its market leadership and credibility. The service targets general internet users and partners who require reliable short links to Google resources. Google's competitive advantage lies in its brand recognition, technological infrastructure, and extensive product portfolio. The simplicity of the g.co page reflects its role as a trust anchor rather than a commercial site. Google's ecosystem partnerships and global reach underpin its sustained growth and market dominance.

Security posture

The security posture of the g.co site is robust, benefiting from Google's enterprise-grade infrastructure and HTTPS enforcement. The absence of forms or user inputs minimizes attack vectors. No security headers were detected in the provided HTML, suggesting room for improvement in defense-in-depth. There are no visible vulnerabilities or exposed sensitive data. Privacy policies and terms are linked, supporting compliance. Incident response and security contact information are not explicitly provided on this page, which could be enhanced for transparency. Overall, the site reflects a mature security culture consistent with a major technology enterprise, though minor enhancements could further strengthen its posture.

Recommendations

  1. Add explicit security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Implement a visible cookie consent mechanism to comply with GDPR and other privacy regulations.
  3. Publish clear security and incident response policies or contact channels on the site to improve transparency and user trust.
  4. Enhance accessibility features to improve usability for all users, including those with disabilities.
  5. Regularly audit third-party scripts like Google Analytics to ensure they comply with privacy standards and minimize user tracking.

Technical notes

Notes

The website uses a minimalistic technical stack primarily consisting of JavaScript, Google Analytics, and Google Fonts. It is hosted on Google's infrastructure with HTTPS enabled, ensuring secure and fast delivery. The HTML is valid and well-structured but lacks advanced SEO and accessibility features. There are no CMS or frameworks detected, reflecting the site's simple informational nature. Performance is fast due to minimal content and efficient hosting. The site could benefit from modern security headers and enhanced mobile optimization. Overall, the technical implementation is solid for the site's purpose but could be modernized for improved compliance and user experience.
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.
