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

Aegean Airlines is a prominent Greek airline operating a comprehensive online platform for flight bookings, travel packages, and customer loyalty programs. The website serves a broad international audience with multilingual support and integrates various travel-related services such as car rentals, hotel bookings, and airport transfers. The company holds a strong market position as a member of the Star Alliance, enhancing its credibility and reach. Technically, the website employs a modern tech stack including AngularJS, jQuery, and Sitecore CMS, supported by advanced analytics and marketing tools like Google Analytics, Oracle Infinity, and Hotjar. The site is well-optimized for mobile devices and accessibility, with structured data enhancing SEO performance. From a security perspective, the site enforces HTTPS, implements security headers, and uses secure forms with validation. No critical vulnerabilities or exposed sensitive data were detected. However, minor compliance gaps exist such as the absence of a visible cookie consent mechanism and a dedicated terms of service page. Overall, the website demonstrates a mature digital presence with strong business credibility and security posture. Strategic improvements in privacy compliance and transparency would further enhance trust and regulatory adherence.

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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

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

    • 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

Aegean Airlines operates in the transportation sector, focusing on passenger air travel and related services. Its business model revolves around direct flight sales, loyalty programs, and ancillary travel services. The airline targets both leisure and business travelers, offering competitive flight deals and travel packages. Its membership in Star Alliance provides a competitive advantage through network connectivity and shared benefits. The website's multilingual support and extensive service offerings indicate a strategy aimed at broad market penetration and customer retention. Partnerships with hotel, car rental, and other travel service providers diversify revenue streams and enhance customer convenience.

Security posture

The website exhibits a strong security posture with enforced HTTPS, appropriate security headers, and secure user authentication mechanisms. The absence of exposed sensitive information and use of validated input fields reduce risk of common web vulnerabilities. However, the lack of a published security policy, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and incident management readiness. Compliance with GDPR is indicated by the privacy policy, but cookie consent mechanisms should be enhanced to meet evolving regulatory standards.

Recommendations

  1. Implement a visible and comprehensive cookie consent banner to ensure full GDPR compliance.
  2. Publish a clear and accessible terms of service page outlining user rights and obligations.
  3. Establish and publicize a security.txt file or vulnerability disclosure policy to encourage responsible reporting.
  4. Provide explicit incident response contact information to improve transparency and trust.
  5. Regularly review and update third-party scripts and analytics tools to mitigate potential security risks.

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.
