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

Hamburg.de is the official digital portal for the Free and Hanseatic City of Hamburg, serving as a comprehensive resource for residents, tourists, and businesses. It provides extensive information on government operations, city services, cultural events, tourism, and transportation. The site is well-branded and professionally designed, with a strong emphasis on accessibility and user experience. However, a critical security gap exists due to the absence of a valid SSL certificate, which undermines secure communications and user trust. The technical infrastructure employs modern JavaScript libraries and accessibility tools but lacks performance metrics and modern TLS protocols. Privacy compliance is supported by a comprehensive privacy policy, though cookie consent mechanisms are not evident. Overall, the site is authoritative and trustworthy but requires urgent security improvements to meet modern standards.

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

Hamburg.de operates as a government portal, positioning itself as the primary digital gateway to Hamburg's public administration, cultural offerings, and tourism services. Its business model is non-commercial, focusing on public service delivery and information dissemination. The portal targets a broad audience including local citizens, tourists, and business stakeholders. The site integrates with partner domains such as hamburg.com for English content, hvv.de for public transport, and karriere.hamburg for employment opportunities, indicating a collaborative ecosystem. The presence of extensive navigation and categorized content suggests a mature content strategy aimed at maximizing user engagement and service accessibility. Growth indicators include active event promotion and integration of accessibility features, supporting inclusivity and broad reach.

Security posture

The website demonstrates partial adherence to security best practices through the implementation of several HTTP security headers such as Strict-Transport-Security, Content-Security-Policy, and X-Frame-Options. Cookies are set with Secure and HttpOnly flags, enhancing session security. However, the absence of a valid SSL/TLS certificate and disabled TLS protocols represent a critical vulnerability, exposing users to potential interception and undermining trust. The lack of OCSP stapling and session resumption further impacts security and performance. No evidence of incident response contacts or security policy documentation was found, indicating potential gaps in security governance and incident management readiness. Overall, the security posture is weak due to fundamental HTTPS deficiencies despite some header protections.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols.
  3. Implement OCSP stapling and session resumption to improve security and performance.
  4. Review and enhance security headers, particularly enabling X-XSS-Protection properly.
  5. Introduce a visible cookie consent mechanism to comply with privacy regulations.
  6. Publish a clear security policy and incident response contact information.
  7. Regularly audit third-party scripts and tracking services for vulnerabilities.
  8. Enhance transparency around data retention and user tracking practices.
Technical notes

Notes

The website uses standard web technologies including HTML5, CSS, and JavaScript, with integration of third-party libraries such as ContentFlow SDK and eyeAble for accessibility. The DNS setup uses multiple authoritative name servers under mcs.de, indicating a stable hosting environment. However, the lack of SSL/TLS support is a major technical deficiency. Performance data is unavailable, but the site appears to be mobile-optimized and accessible, with structured navigation and semantic markup. The absence of CMS identification suggests a custom or proprietary content management solution. The site leverages external domains for media, tracking, and accessibility features, which should be monitored for security and privacy compliance. Overall, the technical infrastructure is modern but requires critical security upgrades.
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.
