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

Hamburger Verkehrsverbund (hvv) operates as the primary public transportation network for Hamburg and its surrounding areas, providing comprehensive services including timetable information, ticket sales, and mobility consulting. The website serves as a digital portal for users to access schedules, purchase tickets, and stay informed about service updates. The platform targets public transit users in the Hamburg region and positions itself as a leading transportation provider with a strong regional presence. Technically, the website employs a modern JavaScript stack with libraries such as jQuery UI, GSAP, and Moment.js to enhance user experience and performance. It features responsive design and accessibility considerations, including keyboard navigation and ARIA roles. The site integrates tracking via etracker for analytics while maintaining GDPR compliance through cookie consent mechanisms and a detailed privacy policy. From a security perspective, the site enforces HTTPS and uses CSRF tokens in forms, indicating attention to secure data handling. However, explicit security headers and a published security policy or vulnerability disclosure are absent, representing areas for improvement. No signs of WAF or blocking mechanisms were detected, allowing full content access. Overall, the website demonstrates a solid balance of usability, compliance, and security suitable for a public transportation entity. Strategic enhancements in security transparency and incident response readiness would further strengthen its posture.

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

3 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

    • 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

  2. 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 hvv website reflects a well-established public transportation authority with a clear focus on serving the Hamburg metropolitan area. Its business model revolves around providing transit services and ticketing solutions, supported by digital tools such as an online shop and mobile apps. The presence of specialized offerings like job tickets, climate tickets, and mobility budgets indicates a diversified service portfolio targeting various customer segments including students, employees, and socially disadvantaged groups. The company leverages partnerships with multiple transit operators and maintains active engagement through social media channels. Growth indicators include digital transformation efforts such as the hvv switch app and open data initiatives. The website's structured navigation and comprehensive content support a strong market position and customer trust.

Security posture

The website exhibits a mature security posture with mandatory HTTPS encryption and secure form handling via CSRF tokens. The presence of cookie consent and privacy policy aligns with GDPR requirements, reflecting compliance awareness. However, the absence of explicit security headers (e.g., Content Security Policy, HSTS) and lack of publicly available security or incident response policies limit transparency and preparedness. No vulnerability disclosure or security.txt file was found, which could hinder coordinated vulnerability reporting. The use of third-party analytics (etracker) is managed with cookie blocking options, mitigating privacy risks. Overall, the security measures are adequate for the site's purpose but could be enhanced by adopting additional best practices and publishing security governance documents.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan accessible from the website.
  2. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to strengthen protection against common web attacks.
  3. Establish a vulnerability disclosure program and provide a security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit third-party scripts and tracking services to minimize privacy risks and ensure compliance with evolving regulations.
  5. Enhance contact information visibility by including verified company emails and phone numbers for customer and security communications.

Technical notes

Notes

The website is built using a modern front-end technology stack with extensive use of JavaScript libraries for UI animations, date/time handling, and lazy loading of images to optimize performance. The presence of ARIA roles and keyboard navigable elements indicates good accessibility practices. The site is mobile-optimized with responsive design and supports multiple languages. Performance is moderate, with room for improvement in load times possibly due to multiple external scripts. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed, but the domain uses third-party DNS providers. Overall, the technical infrastructure supports a robust 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.
