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

1 finding rated critical or high. Fix these first.

  1. 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

Bing holds a significant market position as the second largest search engine globally, leveraging Microsoft's extensive technology infrastructure and brand reputation. Its business model is primarily advertising-supported, enhanced by AI capabilities to improve user experience. The website links to multiple Microsoft services and partner domains, indicating a broad ecosystem integration. The target audience is general internet users worldwide, with services tailored to diverse needs including shopping, news, and productivity tools. The site reflects enterprise-level scale and operational sophistication.

Security posture

The website employs robust security measures including HTTPS, implied security headers, and script nonce usage to mitigate common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the provided content. Privacy compliance is evident through GDPR-aligned cookie consent and a detailed privacy policy. However, no explicit incident response or vulnerability disclosure information was found, suggesting an opportunity to enhance transparency in these areas. Overall, the security posture is strong and appropriate for a high-profile technology service.

Recommendations

  1. Publish explicit security and incident response policies to improve transparency.
  2. Maintain continuous monitoring and updating of third-party libraries to prevent vulnerabilities.
  3. Enhance accessibility features to meet or exceed WCAG standards.
  4. Provide clearer contact channels for security incidents and data protection inquiries.
  5. Regularly review and update privacy and cookie policies to reflect evolving regulations.

Technical notes

Notes

The website uses a modern tech stack including HTML5, CSS3, JavaScript, SVG graphics, and AJAX for dynamic content. It is likely hosted on Microsoft Azure infrastructure, ensuring scalability and performance. The site is well-optimized for mobile devices and includes SEO best practices such as meta tags and Open Graph data. No CMS was explicitly detected, suggesting a custom or proprietary platform. Performance is fast with minimal blocking resources. Technical risks are low, but ongoing maintenance is essential to sustain security and performance.
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.
