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

4 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

  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 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';…

  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

Business profile

Bonvoyo operates in the transportation sector, focusing on corporate benefits for employee mobility. Its business model revolves around providing a digital mobility budget that integrates multiple transport modes, enhancing employer attractiveness and employee satisfaction. The company leverages Deutsche Bahn's brand and infrastructure, indicating strong market positioning. The target audience includes HR, corporate leadership, sustainability managers, and mobility managers. The platform supports flexible payment and usage models, catering to diverse employee needs. Partnerships with Deutsche Bahn and related entities strengthen its ecosystem. Growth potential lies in expanding mobility options and corporate adoption.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS and no exposed sensitive data. Use of asynchronous scripts and modern libraries reduces risk. However, the absence of explicit security headers and published incident response contacts limits transparency. No vulnerability disclosures or security certifications are visible. Privacy policies and cookie consent align with GDPR, indicating good data protection practices. Overall, the security posture is mature but could benefit from enhanced transparency and formalized security documentation.

Recommendations

  1. Implement and publish comprehensive security headers such as Content-Security-Policy and Strict-Transport-Security.
  2. Provide explicit security policy and incident response contact information on the website.
  3. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance visibility of business contact information to improve trust and user engagement.
  5. Regularly audit third-party scripts and analytics tools to ensure no vulnerabilities or privacy issues.

Technical notes

Notes

The website is built on CoreMedia CMS, a robust enterprise content management system, indicating a scalable and maintainable infrastructure. It uses modern JavaScript libraries and asynchronous loading for performance optimization. The site is mobile-optimized with responsive images and accessibility features such as skip links and ARIA labels. SEO is supported by proper meta tags and Open Graph data. Hosting via EuroDNS nameservers suggests reliable European hosting. Performance is moderate, with potential improvements in caching and script optimization. No deprecated or vulnerable libraries were detected. Overall, the technical implementation supports a professional and user-friendly digital presence.
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.
