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 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

  3. 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

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

Corendon Airlines operates in the transportation sector with a focus on air travel and holiday packages. Their business model centers on direct online sales of flight tickets and ancillary services, supported by a strong digital presence and multi-language, multi-currency support. The company leverages partnerships for extended services such as student discounts and mobile app platforms. Their market positioning is reinforced by multiple awards and certifications, indicating competitive advantages in service quality and environmental performance. The target audience includes budget-conscious travelers and holidaymakers in Europe and Turkey. The company shows growth indicators through extensive route offerings and digital marketing investments. The partnership ecosystem includes B2B agent portals and affiliate programs, enhancing distribution channels.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, use of Google reCAPTCHA to prevent automated abuse, and integration of security-aware script loading practices. However, the absence of several recommended security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. No visible vulnerabilities or exposed sensitive data were detected in the HTML content. The site uses secure forms with validation and includes privacy and cookie policies indicating GDPR compliance. Incident response and dedicated security policies are not explicitly found, which could be enhanced to improve readiness. Overall, the security posture is good but could benefit from additional hardening and transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and trust.
  3. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  4. Enhance user privacy controls and provide clear data retention policies to strengthen GDPR compliance.
  5. Conduct periodic security assessments and penetration testing to identify and remediate potential risks.

Technical notes

Notes

The website uses a modern technology stack including JavaScript frameworks and libraries such as jQuery, Select2, and Slick Carousel, supported by Google Tag Manager and various marketing and analytics tools. The site is mobile-optimized with responsive design and accessible navigation. Performance is moderate, with some lazy loading and preloading techniques employed. The CMS or hosting provider is not explicitly identified. The site uses multiple external domains for analytics, marketing, and content delivery, which are well-integrated. Technical debt appears low, but improvements in security headers and performance optimization could be considered to enhance robustness and speed.
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.
