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

Hamburg Airport operates as a major transportation hub in Germany, providing comprehensive flight information, parking, travel services, and passenger amenities. The website targets travelers and visitors, offering multilingual support and detailed service information. The digital infrastructure leverages modern technologies including Cookiebot for GDPR-compliant consent management, etracker and Meta Pixel for analytics and advertising, and is hosted on Microsoft Azure DNS infrastructure. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though explicit security headers and incident response policies are not publicly visible. The website demonstrates good privacy compliance and professional content quality, supporting a trustworthy user experience. Strategic improvements include publishing terms of service, enhancing security headers, and providing clear contact and security incident response information.

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 strong market position as a regional airport in Germany, focusing on transportation services and passenger experience. The business model centers on airport operations, ancillary services such as parking and retail, and partnerships with travel and advertising platforms. The website integrates multiple third-party services for analytics and marketing, indicating a mature digital marketing ecosystem. Growth indicators include multilingual content and comprehensive service offerings. No parent or subsidiary companies are identified from the data. The partnership ecosystem includes known travel and advertising platforms like Kiwi.com and Meta Platforms. The company maintains consistent branding and trust signals through official domain usage and compliance with GDPR.

Security posture

The website exhibits a moderate to strong security posture with HTTPS enabled and a robust cookie consent framework via Cookiebot. Tracking and advertising scripts are managed with user consent, reflecting compliance with privacy regulations. However, the absence of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement. No explicit security policy or incident response contacts are published, which could hinder rapid response to security incidents. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Overall, the security culture appears compliant but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Publish a dedicated terms of service page to clarify user agreements and legal terms.
  2. Implement and configure security headers including CSP, HSTS, and X-Frame-Options to strengthen defense against common web attacks.
  3. Provide explicit contact information for security incidents and data protection officer details to improve incident response readiness.
  4. Consider publishing a security.txt file to facilitate vulnerability disclosure and improve transparency.
  5. Regularly audit third-party scripts and tracking technologies to ensure ongoing compliance and minimize privacy risks.

Technical notes

Notes

The website uses a modern technology stack including JavaScript frameworks, Cookiebot for consent management, and integrates multiple analytics and advertising pixels. Hosting is managed via Microsoft Azure DNS, indicating reliable infrastructure. Performance is moderate with good mobile optimization and accessibility features. SEO is supported by proper meta tags and multilingual support. The site uses external libraries such as Duet Date Picker and etracker analytics. No CMS was explicitly detected from the provided content. Technical risks include lack of visible security headers and incomplete public documentation of security policies. Opportunities exist to modernize security practices and enhance transparency to users.
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.
