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

Hamburger Verkehrsverbund (HVV) operates as the regional public transportation authority for Hamburg and its surrounding areas, providing comprehensive services including timetable information, ticket sales, and customer support. The website serves as a digital portal for users to access travel information, purchase tickets, and stay informed about service updates. The business model focuses on facilitating public transit usage through digital tools and physical service points, targeting residents and visitors in the Hamburg metropolitan region. HVV maintains a strong market position as a key transportation provider in Germany, supported by consistent branding and a professional online presence. Technically, the website employs a variety of modern JavaScript libraries and frameworks to deliver a responsive and interactive user experience. While the site demonstrates good mobile optimization, accessibility, and SEO practices, performance metrics indicate slower load times, suggesting room for optimization. The CMS appears custom-built, and hosting details are not explicitly disclosed. The site integrates tracking via etracker, with a privacy-conscious cookie consent mechanism. From a security perspective, HVV implements several important HTTP security headers and secure cookie attributes. However, the absence of a valid SSL/TLS certificate and disabled TLS protocols represent critical vulnerabilities, severely impacting the security posture. DNS security features like DNSSEC and CAA are not enabled, further exposing the domain to potential DNS-based attacks. No explicit security or incident response policies are publicly available, and no vulnerability disclosure or security.txt files were found. Overall, HVV's website is functional and professionally presented but requires urgent improvements in SSL/TLS deployment and DNS security to protect user data and maintain trust. Strategic enhancements in security policies and incident response transparency would further strengthen the organization's digital resilience.

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.

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

HVV holds a dominant position in the Hamburg public transportation sector, offering a broad range of services from ticketing to mobility management. Its business model leverages digital platforms to enhance customer engagement and streamline operations. The presence of an online shop and integration with mobile apps indicates diversified revenue streams and a focus on customer convenience. Partnerships with related domains and use of multiple social media channels support brand visibility and customer outreach. The organization targets a wide demographic including daily commuters, students, and special groups such as refugees and corporate clients. Growth indicators include active promotion of new services and events, as well as continuous updates to service information. The ecosystem includes external partners for email security and reporting, reflecting a mature operational environment.

Security posture

HVV demonstrates awareness of security best practices through the use of multiple HTTP security headers and secure cookie settings. However, the lack of a valid SSL certificate and disabled TLS protocols constitute a critical security gap, exposing users to risks such as data interception and man-in-the-middle attacks. The absence of DNSSEC and CAA records further weakens domain security. No public-facing security policies or incident response contacts were identified, indicating potential gaps in transparency and preparedness. The use of etracker for analytics is privacy-conscious with cookie consent, but the overall security posture is undermined by fundamental SSL/TLS deficiencies. Immediate remediation of certificate issues and enhancement of DNS security are essential to elevate the security maturity.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS and protect user data.
  2. Enable modern TLS protocols (TLS 1.2 or TLS 1.3) and configure OCSP stapling and session resumption for improved security and performance.
  3. Implement DNSSEC and CAA records to enhance DNS integrity and certificate issuance control.
  4. Publish clear security policies and incident response procedures, including dedicated contact channels for security issues.
  5. Conduct regular security audits and vulnerability assessments to identify and mitigate risks proactively.
Technical notes

Notes

The website uses a rich set of JavaScript libraries including jQuery UI, GSAP for animations, ScrollMagic for scroll-based effects, Moment.js for date handling, and various UI enhancement plugins like bLazy for lazy loading and Masonry for layout. The site is mobile-optimized and accessible, with good SEO metadata and Open Graph tags. However, performance data indicates slow loading, possibly due to heavy scripts or unoptimized resources. The CMS appears custom or proprietary, with no common CMS signatures detected. Hosting provider details are not explicit, and DNS configuration lacks advanced security features. The absence of valid SSL/TLS certificates is a major technical risk. Overall, the technical infrastructure supports a modern user experience but requires improvements in security and performance optimization.
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.
