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. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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

SWISS holds a strong market position as a premium airline within the transportation sector, targeting general travelers worldwide. Its business model centers on passenger air transport, supplemented by ancillary services such as baggage handling, seat reservations, upgrades, and partner offers including hotels and rental cars. The company benefits from its affiliation with Lufthansa Group and Star Alliance, enhancing its global reach and service offerings. The website reflects a mature digital presence with strategic partnerships and affiliate programs, indicating a robust ecosystem and growth orientation.

Security posture

The website exhibits a mature security posture with enforced HTTPS, secure OAuth2-based login flows, and session management. Security headers are likely implemented, and no sensitive data is exposed in the HTML content. However, the absence of publicly available security policies, incident response procedures, or vulnerability disclosure programs suggests room for improvement in transparency and readiness. The site complies with GDPR and includes cookie consent mechanisms, supporting data protection best practices. No critical vulnerabilities or security issues were detected during analysis.

Recommendations

  1. Publish a dedicated security policy and incident response information to enhance transparency and user trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Enhance contact information with explicit security and abuse contact channels.
  4. Regularly audit third-party scripts and tracking technologies to minimize privacy risks.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website is built on a modern technology stack including JavaScript frameworks, Adobe Helix RUM for real user monitoring, and Tealium for tag management. It uses a modular design system (Maui Design System) and is likely powered by a robust CMS such as Adobe Experience Manager. Hosting on Akamai CDN ensures high availability and performance. The site is mobile-optimized and accessible, with good SEO practices evident in meta tags and structured data. Technical risks are minimal, but continuous monitoring of third-party dependencies and performance metrics is recommended to sustain operational excellence.
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.
