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

5 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

    • 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

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 represents a government sector entity focused on providing public information and services. It targets a broad audience including citizens, businesses, and tourists in Hamburg. The business model is service-oriented, funded and operated by the city government. The portal likely generates value through facilitating access to municipal services and information dissemination. The absence of commercial advertising and affiliate programs aligns with its government nature. The partnership ecosystem includes hosting providers and analytics services. Growth indicators are not explicit but the site’s enterprise scale and consistent branding suggest a mature digital presence.

Security posture

The security maturity level is moderate to good. HTTPS is enforced, ensuring encrypted communications. However, the lack of explicit security headers such as Content-Security-Policy, X-Frame-Options, and others reduces defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the analyzed content. There is no visible incident response or vulnerability disclosure information, which is a gap in security culture and transparency. GDPR compliance indicators are weak due to missing privacy and cookie policies. The site employs accessibility tools, indicating attention to inclusive design. Overall, the security posture is adequate for a government portal but could be improved with enhanced policies and headers.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with clear GDPR compliance statements.
  2. Implement a cookie consent mechanism to inform and obtain user consent for tracking.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection.
  4. Provide clear contact information for security incidents and designate a data protection officer publicly.
  5. Introduce a vulnerability disclosure policy and publish a security.txt file to improve transparency and incident response readiness.

Notes

The website uses a modern technology stack with HTML5, CSS3, and JavaScript, including specialized libraries like Shaka Player for media and eyeAble for accessibility. Hosting is managed by mcs.de, a professional hosting provider, as indicated by the nameservers. Performance is moderate with good mobile optimization and accessibility features. SEO is supported by proper meta tags and canonical links. However, no CMS or specific frameworks were detected in the provided snippet. The site uses eTracker for analytics, which is a European tracking service. Technical risks include the absence of explicit security headers and incomplete privacy compliance documentation.
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.
