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

8 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

      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

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

FlixBus Sverige holds a strong market position as a large-scale transportation provider with extensive European coverage. Their business model focuses on direct-to-consumer online sales via website and app, supplemented by physical sales points. The company leverages partnerships across multiple country-specific domains to localize services. Growth indicators include continuous network expansion and digital innovation. The company maintains a strong social media presence and brand consistency, enhancing customer trust and engagement. Revenue streams primarily derive from ticket sales and ancillary services such as airport shuttles. The company operates in the transportation sector with a focus on sustainability and affordability.

Security posture

The website exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and use of a consent management platform. No critical vulnerabilities or exposed sensitive data were detected. However, the lack of publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. GDPR compliance is well addressed through privacy and cookie policies. The site’s use of third-party analytics and advertising scripts is managed with user consent. Incident response readiness and security culture indicators are not explicitly visible, suggesting room for improvement in transparency and communication.

Recommendations

  1. Publish a dedicated security policy page detailing security practices and compliance.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance visibility of customer support contact information including phone and email.
  5. Regularly review and audit third-party scripts and dependencies for security vulnerabilities.

Technical notes

Notes

The website is built using React and Drupal CMS, served via Amazon Cloudfront CDN, ensuring good performance and scalability. It uses modern JavaScript libraries and frameworks, with asynchronous loading of analytics and marketing scripts to optimize load times. The site is mobile-optimized with responsive design and accessibility features such as ARIA labels and keyboard navigation support. SEO is supported by proper meta tags, Open Graph data, and structured JSON-LD schema. Technical risks are minimal, though continuous monitoring of third-party scripts is advised to mitigate potential vulnerabilities.
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.
