Security report for lh.com

Deutsche Lufthansa AG · Transportation · Germany

Medium risk. 4 critical or high findings in GDPR outside view and SSL/TLS.

Security score

56/100

Risk levelMedium

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

Deutsche Lufthansa AG operates a comprehensive airline website offering flight booking and travel management services to a global audience. The site reflects Lufthansa's position as a leading international airline with a broad network and premium service offerings. The technical infrastructure leverages modern web technologies including Adobe Helix, Maui Design System, and Akamai CDN, ensuring a responsive and accessible user experience. While the website is rich in content and professionally designed, the SSL certificate is currently invalid, which poses a security risk. Security headers are well implemented, but the absence of a cookie consent mechanism indicates partial privacy compliance. Overall, the site demonstrates a mature digital presence with room for improvement in security and privacy practices.

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

4 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

Lufthansa's website clearly targets air travelers worldwide, providing extensive services from flight booking to additional travel amenities. The business model focuses on transportation and travel services, supported by a strong loyalty program (Miles & More) and partnerships with car rental and hotel providers. The site integrates multiple subsidiaries and partners, reinforcing Lufthansa Group's market position. The presence of comprehensive travel information and customer service links indicates a customer-centric approach. The use of advanced analytics and marketing tools suggests a data-driven strategy to enhance customer engagement and revenue streams.

Security posture

The website employs several security best practices including a robust Content Security Policy, secure and HttpOnly cookies, and multiple security headers. However, the invalid SSL certificate significantly undermines the security posture, potentially exposing users to man-in-the-middle attacks. No critical vulnerabilities or malware indicators were found. The lack of explicit incident response or security policy pages suggests an opportunity to improve transparency and readiness. GDPR compliance is indicated by the privacy policy, but cookie consent mechanisms are missing, which could lead to regulatory scrutiny.

Recommendations

  1. Renew and properly configure the SSL certificate to ensure HTTPS security.
  2. Implement a comprehensive cookie consent banner to comply with GDPR and ePrivacy regulations.
  3. Publish clear security and incident response policies to enhance transparency and trust.
  4. Regularly audit third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enable full HSTS with includeSubDomains and preload to enforce HTTPS across all subdomains.
Technical notes

Notes

The website is built on a modern tech stack with Adobe Helix and Maui Design System, served via Akamai CDN for performance optimization. It uses multiple analytics and marketing tools including Google Analytics, Tealium, and Quantum Metric, indicating advanced user behavior tracking. The site is mobile-optimized and accessible, with good SEO practices evident from meta tags and structured navigation. Performance metrics are moderate, suggesting potential for further optimization. The invalid SSL certificate is a critical technical issue that should be addressed immediately to maintain user trust and security.
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.
