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 operates within the technology sector as an essential service under Microsoft Corporation. Its business model is primarily advertising-supported, leveraging Microsoft Advertising and integrated marketing tools like Microsoft Rewards. The platform targets a broad audience of internet users worldwide, providing search and discovery services. Bing's ecosystem includes partnerships with MSN, Microsoft 365, and Outlook, enhancing user engagement and cross-service integration. The site’s content and navigation reflect a focus on delivering relevant, timely information and multimedia content. Bing's market position as a major search engine is supported by its enterprise backing and continuous innovation in AI and search technologies.

Security posture

The website exhibits a strong security posture with enforced HTTPS, implied use of Content Security Policy, and secure handling of user inputs in search forms. No security headers were explicitly listed in the HTML but are likely present given Microsoft's standards. No vulnerabilities or exposed sensitive data were detected in the content. Privacy compliance is evident through cookie consent banners and links to comprehensive privacy policies. However, no explicit incident response or security policy pages were found, which is common for large consumer-facing platforms that centralize such information elsewhere. Overall, Bing maintains a secure environment suitable for its scale and user base.

Recommendations

  1. Publish or link to a dedicated security policy and incident response page for transparency.
  2. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  3. Enhance accessibility features to meet or exceed WCAG standards.
  4. Provide clearer contact information for security and privacy inquiries.
  5. Maintain and update privacy and cookie consent mechanisms to align with evolving regulations.

Technical notes

Notes

Bing’s technical infrastructure is modern and robust, utilizing advanced JavaScript, SVG graphics, and asynchronous loading techniques to optimize user experience. The site is hosted on Microsoft Azure or equivalent Microsoft infrastructure, ensuring scalability and reliability. Performance is fast with responsive design for mobile devices. SEO and accessibility are well implemented, with proper meta tags and ARIA roles. The site uses Microsoft Clarity for analytics and Microsoft Advertising for monetization. No CMS was detected, likely due to custom Microsoft-built platform. Overall, the technical implementation supports a high-quality, enterprise-grade web service.
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.
