0–100, higher is better. How it is calculated

Detroit Grand Prix, Inc operates the Chevrolet Detroit Grand Prix, an annual motorsport street racing event held in Downtown Detroit. The website serves as a comprehensive platform for ticket sales, event information, news updates, and partnership opportunities, targeting motorsport fans and event attendees. The company holds a strong market position within the motorsport and event promotion sectors, leveraging digital channels and social media to engage its audience. Technically, the website employs modern web technologies including jQuery, Google Tag Manager, Marketo forms, and social media SDKs. It features multimedia content such as videos and social feeds, with good mobile optimization and accessibility. SEO practices are well implemented with appropriate meta tags and structured navigation. From a security perspective, the site uses HTTPS and integrates secure third-party services. However, explicit security headers are not detected, and there is no visible cookie consent mechanism, which are areas for improvement. The absence of WHOIS data limits domain trust assessment but the professional presentation and consistent branding support legitimacy. Overall, the website demonstrates a mature digital presence with strong business credibility but could enhance privacy compliance and security posture to further strengthen trust and regulatory adherence.

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

4 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 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

The Detroit Grand Prix is positioned as a key motorsport event in the United States, attracting a dedicated fan base and corporate sponsors. Its business model centers on event ticket sales, hospitality, and sponsorship partnerships. The website's integration with official merchandise stores and marketing platforms like Marketo indicates a well-developed partnership ecosystem. Growth indicators include active news updates and a mobile app to enhance attendee experience. The company targets motorsport enthusiasts, local communities, and corporate partners, maintaining a medium-sized operational scale with consistent branding and professional content.

Security posture

The website exhibits a good security baseline with HTTPS enforced and no exposed sensitive data in the HTML. Use of reputable third-party analytics and marketing tools is evident. However, the lack of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. There is no published vulnerability disclosure or incident response contact information, which are recommended for transparency and readiness. Privacy compliance is partial, with a privacy policy present but no cookie consent banner detected. Overall, the security posture is solid but could be improved with enhanced headers, explicit consent mechanisms, and published security policies.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to mitigate common web vulnerabilities.
  2. Add a cookie consent banner to comply fully with GDPR and other privacy regulations.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  5. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities and ensure compliance.

Technical notes

Notes

The website uses a modern tech stack with jQuery, Google Tag Manager, Marketo forms, and social media SDKs. It loads multimedia content efficiently with lazy loading and asynchronous scripts. The site is mobile-optimized and accessible, with clear navigation and SEO-friendly meta tags. Performance is moderate, with potential improvements in script optimization and caching. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not evident from the content. Overall, the technical infrastructure supports a professional and engaging user experience but could benefit from performance tuning and enhanced security configurations.
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.
