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

3 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 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

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

The company operates as a small-sized online travel agency targeting European travelers interested in self-drive tours. Their business model centers on direct online bookings combined with personalized itinerary planning. Rebel Travel leverages partnerships with insurance and car rental providers and maintains affiliations such as SGR to enhance trust. The website content and structure support a clear market positioning as a specialist in autorondreizen, with offerings spanning multiple European countries and travel themes like wellness, cycling, and culture. The presence of social proof via Trustpilot and active social media channels further strengthens their market credibility. Growth potential lies in expanding digital marketing and enhancing compliance to meet evolving privacy regulations.

Security posture

The website demonstrates a mature security posture with HTTPS enabled and multiple security headers implemented, reducing common web vulnerabilities. No exposed sensitive data or vulnerable libraries were detected in the provided content. However, the lack of a published security policy or incident response contact limits transparency and preparedness from a compliance perspective. The absence of a vulnerability disclosure policy or security.txt file suggests an opportunity to formalize security communication channels. Overall, the security measures are adequate for the business scale but could be enhanced to align with best practices and regulatory expectations.

Recommendations

  1. Implement a visible cookie consent banner to ensure compliance with EU cookie laws and enhance user transparency.
  2. Publish a dedicated security policy and incident response contact information to improve trust and regulatory compliance.
  3. Develop and publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  4. Enhance website accessibility features to meet WCAG standards and improve user inclusivity.
  5. Regularly review and update third-party scripts and dependencies to mitigate potential security risks.

  1. Website is professionally designed and well-structured for travel services.
  2. Clear contact information and multiple communication channels provided.
  3. Use of modern web technologies and integration with Google services.
  4. No signs of malicious content or security issues detected.
  5. Lack of visible cookie consent mechanism may pose compliance risk.

Technical notes

Notes

The website uses a combination of Google-hosted fonts, jQuery libraries, Google Analytics, Google Tag Manager, and Google Maps API, indicating a reliance on well-supported and widely used technologies. The CMS appears custom or proprietary, with no explicit identification of popular platforms like WordPress or Drupal. Performance is moderate, with some asynchronous script loading and image lazy loading techniques observed. Mobile optimization is good, supported by responsive design elements and viewport meta tags. SEO is addressed with appropriate meta tags and structured navigation menus. Technical risks include dependency on multiple external services and the need for ongoing maintenance of third-party scripts to avoid 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.
