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 LLC operates g.co as a strategic URL shortening service to enhance user trust and brand consistency across its vast ecosystem of products. The service supports Google's business model by simplifying access to Google services and reinforcing brand recognition. The domain's registration and technical setup reflect Google's enterprise-grade standards. While the site itself is minimal, it integrates with Google's broader digital ecosystem, including analytics and policy frameworks. The lack of direct contact information on this page aligns with its role as a utility rather than a customer-facing service. Google's market position as a technology leader is reinforced by the domain's legitimacy and consistent branding.

Security posture

The security posture of g.co is strong, benefiting from Google's enterprise infrastructure. HTTPS is enforced, and domain status flags prevent unauthorized domain modifications. However, DNSSEC is not enabled, which could be improved to protect against DNS spoofing. No explicit security headers were detected in the HTML content, suggesting an opportunity to enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were found. The use of Google Analytics indicates moderate user tracking, balanced by comprehensive privacy policies. Incident response and security policy details are not directly available on this page but are likely covered under Google's broader corporate policies.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing attacks.
  2. Implement explicit security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance web security.
  3. Consider adding visible security or incident response contact information to improve transparency.
  4. Maintain and regularly audit third-party scripts like Google Analytics to ensure no vulnerabilities are introduced.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website uses a lightweight, minimal HTML structure with Google-hosted CSS and fonts, ensuring fast load times and good mobile optimization. Google Analytics is used for tracking user interactions. The domain is hosted on Google's infrastructure with Google name servers, providing robust hosting and DNS reliability. No CMS or third-party frameworks were detected, indicating a custom-built static or server-rendered page. Performance is fast, but accessibility and SEO optimizations are basic. The lack of DNSSEC and security headers represents minor technical debt. Overall, the technical implementation is solid, leveraging Google's infrastructure and best practices for a simple informational page.
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.
