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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. 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.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

FlixBus Italia holds a significant market position as a major player in affordable intercity bus travel, targeting a broad audience of travelers within Italy and Europe. Its business model centers on providing extensive route coverage, user-friendly digital booking platforms, and value-added services like onboard Wi-Fi and real-time tracking. The company leverages partnerships and subsidiaries to expand its service offerings and geographic reach. The presence of comprehensive privacy and cookie policies, along with active social media engagement, supports customer trust and brand loyalty. The lack of direct contact information on the homepage suggests reliance on dedicated support portals for customer service. FlixBus's sustainability initiatives and corporate governance disclosures further enhance its market credibility.

Security posture

The website exhibits a strong security posture with enforced HTTPS, robust security headers, and no visible exposure of sensitive data. Use of modern monitoring tools like Datadog RUM indicates active performance and security monitoring. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program limits transparency in security governance. No critical vulnerabilities or suspicious scripts were detected in the analysis. The site follows best practices for secure session management and data protection, aligning with GDPR compliance. Recommendations include publishing explicit security and incident response information and establishing a formal vulnerability disclosure channel to enhance security maturity and stakeholder confidence.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Provide clear incident response contact details to facilitate reporting and handling of security incidents.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Add data protection officer contact information to comply fully with GDPR transparency requirements.
  5. Regularly review and audit third-party scripts and integrations to mitigate potential security risks.

Technical notes

Notes

The website is built on Drupal CMS and employs a modern tech stack including JavaScript frameworks, CSS, and HTML5 standards. It integrates third-party services such as Datadog for real user monitoring and Adjust for mobile app attribution and marketing analytics. The site uses CDN services for content delivery, ensuring fast load times and global availability. Mobile optimization is excellent, with responsive design and adaptive images. Accessibility features are implemented to a good standard, supporting diverse user needs. SEO is well addressed through meta tags, structured data (JSON-LD), and hreflang attributes for multilingual support. The technical infrastructure supports a robust and scalable user experience with minimal technical debt observed.
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.
