Brussels Airlines · Transportation · Belgium

Medium risk. 5 critical or high findings in Security headers and GDPR outside view.

Security score

59/100

Risk levelMedium

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

Brussels Airlines is an enterprise-level transportation company operating primarily in Belgium and is part of the Lufthansa Group. The website is currently inaccessible due to a Web Application Firewall or security mechanism, resulting in an Access Denied page served by AkamaiGHost. This prevents access to any meaningful content, metadata, or business information on the site. The technical infrastructure includes Akamai CDN and Barracuda Networks for email security, with SPF and DMARC records properly configured. However, the SSL/TLS configuration is severely lacking, with no valid certificate or modern TLS protocols enabled, exposing the site to significant security risks. Security headers are minimal, and no privacy or cookie policies are detectable on the landing page. Overall, the site’s security posture is weak, and the lack of accessible content limits the ability to assess business credibility or compliance. The site is heavily tracked by multiple advertising and analytics services as indicated by the content security policy, but these cannot be verified due to the blocked content.

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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

Brussels Airlines operates in the transportation sector as a subsidiary of the Lufthansa Group, indicating a strong market position within European air travel. The DNS and CSP data suggest partnerships with major travel and advertising platforms such as Amadeus and Google services. The business model likely revolves around passenger air transport and related services. The presence of multiple sister companies within the Lufthansa Group suggests a broad partnership ecosystem. However, the website’s current inaccessibility and lack of public-facing content hinder detailed insights into revenue streams, customer engagement, or growth indicators.

Security posture

The security posture of the website is currently poor due to the absence of a valid SSL certificate and lack of support for modern TLS protocols. Although SPF and DMARC records are properly configured, the site lacks critical security headers beyond Content-Security-Policy. The presence of HttpOnly and Secure flags on cookies is a positive practice. The site is protected by a WAF, likely Akamai, which blocks access and prevents content scraping or analysis. This WAF protection is a double-edged sword: it enhances security but also limits transparency and user access. No incident response or vulnerability disclosure information is publicly available. Overall, the site requires urgent improvements in SSL/TLS deployment, header configuration, and transparency to improve trust and compliance.

Recommendations

  1. Deploy a valid SSL/TLS certificate supporting TLS 1.2 and TLS 1.3 to secure all website traffic.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives.
  3. Expand security headers to include X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and others to harden security.
  4. Publish clear privacy, cookie, and security policies accessible from the homepage to improve compliance and user trust.
  5. Implement and publicize a vulnerability disclosure policy and incident response contact information.
  6. Improve website accessibility and performance once content is unblocked to enhance user experience.
  7. Review and optimize third-party tracking and advertising scripts to balance marketing needs with privacy compliance.
Technical notes

Notes

The website is hosted behind Akamai’s CDN and WAF infrastructure, which currently blocks direct access to the homepage, returning an Access Denied message. DNS records indicate robust email security with Barracuda Networks and proper SPF and DMARC configurations. However, the SSL/TLS configuration is non-existent or invalid, with no supported TLS versions or cipher suites detected. The site uses a complex Content-Security-Policy allowing many third-party domains, indicating extensive use of external scripts and tracking technologies. Performance data is unavailable due to blocked content, but the presence of Akamai suggests potential for good global delivery performance. The lack of accessible HTML content prevents evaluation of CMS, frameworks, or platform technologies. Overall, the technical infrastructure is modern but currently inaccessible, limiting operational transparency.
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.
