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

10 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

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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';…

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

Bulgaria Air operates in the transportation sector as Bulgaria's national airline, leveraging partnerships with insurance (Armeec), car rental (Sixt), and banking (Central Cooperative Bank) to enhance customer offerings. The business model centers on passenger air travel with additional revenue streams from loyalty programs and ancillary services. The company targets a broad customer base including leisure and business travelers. The website content and structure indicate a well-established brand with consistent messaging and strong trust signals. Growth indicators include active promotions, seasonal route announcements, and engagement in cultural sponsorships. The partnership ecosystem supports a comprehensive travel experience, reinforcing market competitiveness.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, secure form submissions, and no visible exposure of sensitive data. Tracking and marketing scripts are loaded asynchronously to minimize performance impact. However, the absence of explicit Content-Security-Policy and X-Frame-Options headers suggests room for improvement in mitigating clickjacking and cross-site scripting risks. No vulnerability disclosures or incident response contacts are published, which could be enhanced to improve transparency and readiness. Overall, the security measures align with industry standards for airline websites, supporting customer trust and data protection.

Recommendations

  1. Implement Content-Security-Policy and X-Frame-Options HTTP headers to strengthen security against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to enhance transparency and preparedness.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Enhance accessibility features to improve compliance with WCAG standards.
  5. Consider adding data retention policies and clearer privacy notices regarding analytics and tracking.

Technical notes

Notes

The website uses a combination of jQuery, Select2, Flatpickr, Owl Carousel, and OneSignal SDK for push notifications, integrated with Google Tag Manager and Facebook Pixel for analytics and marketing. The HTML is well-structured with meta tags for SEO and social sharing (Open Graph, Twitter Cards, JSON-LD). Mobile optimization is good with responsive design and viewport settings. Performance is moderate, with asynchronous loading of scripts. No CMS is explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The site could benefit from enhanced security headers and improved accessibility compliance to reduce technical debt and future-proof the platform.
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.
