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

The website 'DB Bus Challenge' is an interactive online game designed to engage users by simulating bus transportation challenges, likely related to Deutsche Bahn's bus services in Germany. The site targets a general audience interested in public transportation and casual gaming. The business model appears promotional, aiming to increase engagement and brand awareness rather than direct sales. The website is relatively small in scale with basic content and moderate branding consistency. Technically, the site uses a JavaScript-based frontend with RequireJS and jQuery, implementing device detection and responsive design for mobile optimization. Performance is moderate with basic SEO and accessibility features. No CMS or backend technologies are evident from the HTML content. Hosting details are limited but DNS servers indicate a standard hosting environment. From a security perspective, the site uses HTTPS but lacks visible security headers and formal privacy or cookie policies, which are critical for GDPR compliance given the European audience. No contact or incident response information is provided, limiting transparency and trust. No vulnerabilities or exposed sensitive data were detected in the static content. Overall security posture is average but could be improved with standard best practices. The overall risk is moderate with no critical issues detected. Strategic recommendations include adding privacy and cookie policies, improving security headers, providing clear contact and incident response information, and enhancing SEO and accessibility. These improvements would increase user trust, compliance, and security maturity.

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.

Priority findings

10 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

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 website serves as a promotional platform for a game themed around public transportation, likely linked to Deutsche Bahn's bus services. Its market positioning is niche, focusing on engagement rather than direct commercial transactions. The business model leverages gamification to enhance brand interaction. Target customers are general users interested in transportation and casual gaming. There is no evidence of revenue streams beyond promotional engagement. The partnership ecosystem is not visible from the site. Growth indicators and strategic operations are not disclosed. Competitive advantages include brand association with Deutsche Bahn and a unique interactive experience. However, lack of detailed business information and contact data limits transparency. The site is likely a small-scale project or campaign rather than a standalone business entity.

Security posture

The current security maturity level is basic. The site uses HTTPS, which is mandatory, but lacks important security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options. No privacy or cookie policies are present, indicating compliance gaps with GDPR. No incident response or security contact information is provided, reducing readiness for security events. No vulnerabilities or exposed sensitive data were found in the static content, but the absence of security best practices and policies is a concern. Data protection practices appear minimal, with no evidence of user data collection forms or tracking scripts. The security culture is not evident from the site. Overall, the site should implement standard security headers, privacy policies, and incident response contacts to improve its security posture and compliance.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to ensure GDPR compliance.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Provide clear contact information including security incident response channels to improve transparency and readiness.
  4. Enhance SEO and accessibility features to improve user experience and search engine ranking.
  5. Regularly audit and update third-party libraries and scripts to avoid vulnerabilities and maintain performance.

Technical notes

Notes

The website uses a JavaScript-heavy frontend architecture with RequireJS for module loading and jQuery for DOM manipulation. Device detection scripts enable responsive design and tailored user experience across desktop, tablet, and mobile devices. The site loads CSS and JS resources with versioning parameters to manage caching. No backend or CMS technologies are detectable from the HTML content. Hosting provider details are not disclosed, but DNS name servers indicate a standard hosting environment. Performance is moderate with asynchronous script loading. SEO metadata is minimal but includes Open Graph tags for social sharing. Accessibility features are basic, with no ARIA roles or landmarks detected. There is room for modernization by adopting more semantic HTML, improving accessibility, and enhancing SEO metadata.
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.
