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. 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

      SSL Certificate Expires Soon

      SSL certificate expires in 10 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates
    • 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

Hamburg Airport holds a significant market position as a regional airport serving Hamburg and surrounding regions. Its business model revolves around airport operations, passenger facilitation, and ancillary services such as parking and retail. The website reflects a mature digital presence with integration of multiple third-party services for analytics and marketing, indicating a focus on data-driven customer engagement. Partnerships with companies like Kiwi.com and bookingkit.net suggest a collaborative ecosystem for travel and booking services. The absence of explicit business contact details on the homepage may indicate a focus on direct passenger service rather than B2B interactions. The airport's branding is consistent and content quality is good, supporting its reputation as a reliable transportation entity.

Security posture

The website demonstrates a solid security posture with HTTPS enabled and use of a reputable cookie consent management platform (Cookiebot) ensuring GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of visible security policy documentation and incident response contact information represents a gap in transparency and readiness communication. The presence of multiple third-party scripts necessitates ongoing monitoring for vulnerabilities. Security headers were not explicitly detected in the provided data, suggesting room for improvement in HTTP header security hardening. Overall, the site is secure but could enhance its security maturity by publishing formal policies and improving header configurations.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  3. Implement and enforce security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Regularly audit and update third-party scripts to mitigate risks from external dependencies.
  5. Consider publishing a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built using modern JavaScript libraries and frameworks, including Cookiebot for consent management and Duet Date Picker for UI components. Analytics and marketing integrations include Etracker, Google Analytics, Facebook Pixel, and The Trade Desk, indicating a comprehensive approach to user behavior tracking and advertising. Hosting on Microsoft Azure DNS suggests reliable and scalable infrastructure. Performance is moderate with good mobile optimization and accessibility features. SEO is supported by proper meta tags and Open Graph data. There is no explicit CMS detected from the provided data. The technical implementation is robust but could benefit from enhanced security header configurations and potential CMS identification for better content management insights.
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.
