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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • 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

Nasdaq holds a dominant position in the financial services sector as a major stock exchange and market data provider. Its business model revolves around providing market access, data services, and technology solutions to institutional and retail investors. The website supports Nasdaq's brand by offering market insights, educational resources, and access to various Nasdaq-related products and services. The presence of partner domains such as Nasdaq Private Market and Nasdaq Data Link indicates a broad ecosystem. The company targets a professional audience including traders, investors, and corporate clients. The site’s content and navigation support Nasdaq’s strategic goals of market leadership and customer engagement.

Security posture

The website employs industry-standard security practices including HTTPS, security headers, and cookie consent frameworks. There is no evidence of exposed sensitive data or vulnerable libraries in the HTML content. However, the absence of a publicly accessible security policy, incident response contact, or vulnerability disclosure program represents a gap in transparency. The extensive use of third-party scripts for advertising and analytics introduces potential risk vectors that should be regularly audited. Overall, the security posture is solid but could be enhanced by publishing formal security documentation and providing direct security contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide direct security contact emails such as security@nasdaq.com or abuse@nasdaq.com.
  4. Regularly review and audit third-party scripts to minimize security risks.
  5. Enhance data protection officer contact visibility to support GDPR compliance.

Advertising is managed via Google AdSense and WSOD, with responsive ad placements. Performance monitoring is implemented using Boomerang. The site is mobile-optimized with responsive design and accessibility features. SEO is supported by comprehensive meta tags, Open Graph, and JSON-LD structured data. Hosting provider details are not explicitly identified in the HTML content. Overall, the technical infrastructure is robust and well-implemented, supporting a high-quality 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.
