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. 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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. 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"

  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

DERTOUR operates in the hospitality and transportation sectors as an essential entity within the REWE Group. Its business model focuses on online travel bookings and tour operations, serving a broad consumer base in Germany and Europe. The company leverages partnerships and a broad portfolio of travel products to maintain competitive advantages. The website content and navigation reflect a mature digital presence with clear calls to action and marketing campaigns. The absence of direct contact emails or phone numbers in the HTML suggests reliance on contact forms and local travel agencies for customer interaction. The company demonstrates good marketing and analytics integration, supporting data-driven business decisions.

Security posture

The website exhibits a mature security posture with enforced HTTPS, multiple security headers, and a consent management platform ensuring GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of published security policies, incident response plans, or vulnerability disclosure mechanisms indicates room for improvement in transparency and security culture. The use of third-party scripts and ad networks is managed with consent, reducing privacy risks. Overall, the security posture is good but could be enhanced by publishing explicit security documentation and providing direct security contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency.
  2. Implement and publish a vulnerability disclosure policy or security.txt file.
  3. Provide direct security contact emails such as security@ or abuse@ addresses.
  4. Regularly review and audit third-party scripts to minimize potential vulnerabilities.
  5. Enhance data retention and privacy transparency by detailing policies on the website.

Technical notes

Notes

The website uses a modern React-based framework (Next.js) with server-side rendering and static asset delivery via AWS Cloudfront CDN, ensuring fast load times and good scalability. The presence of Usercentrics indicates a mature approach to consent management. Adobe DTM is used for tag management and analytics, supporting advanced marketing capabilities. The site is mobile optimized and accessible, with proper meta tags and SEO-friendly structure. No CMS was explicitly detected, suggesting a custom or proprietary solution. Technical risks are minimal, but continuous monitoring of third-party dependencies is recommended to maintain security and performance.
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.
