0–100, higher is better. How it is calculated

Bahn und Hotel is a German travel comparison portal specializing in train and hotel package deals, primarily targeting travelers interested in 1st class train travel within Germany and select European cities. The website is affiliated with DB Fernverkehr AG, a major player in the German transportation sector, and leverages official Deutsche Bahn branding and social media channels. The platform offers users an interactive search experience with date pickers, traveler selectors, and destination teasers, supporting a user-friendly booking process. Technically, the website employs modern web technologies including Laravel Livewire for reactive components, Alpine.js for frontend interactivity, and ES modules for JavaScript. Hosting and DNS are managed via Amazon Registrar, Inc., indicating a reliable infrastructure. The site is mobile optimized and accessible, with good SEO practices evident in meta tags and structured content. From a security perspective, the site enforces HTTPS and uses CSRF tokens in forms, but lacks DNSSEC and visible security headers, which are recommended for enhanced protection. No explicit security or incident response policies are publicly available, and no vulnerability disclosure or security.txt files were found. Privacy compliance is supported by a comprehensive privacy policy, though no cookie consent mechanism was detected. Overall, Bahn und Hotel presents a professional and trustworthy online presence with a solid technical foundation and good business credibility. Security posture is adequate but could be improved by implementing DNSSEC, security headers, and explicit incident response information. Privacy compliance is good but would benefit from a visible cookie consent mechanism.

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

9 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
    • Critical

      Critical Service Exposed: PostgreSQL

      Port 5432 (PostgreSQL) is publicly accessible - PostgreSQL - Database server

      What to do: Immediately restrict access to PostgreSQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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"

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 · found on this site
  • 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 website operates as a niche travel comparison and booking platform focused on train and hotel packages, leveraging the strong brand and infrastructure of Deutsche Bahn. Its market positioning targets travelers seeking convenient and cost-effective 1st class train travel options in Germany and Europe. The business model is primarily commission-based through bookings. The platform's integration with official DB social media channels and links to DB corporate pages enhances its credibility and partnership ecosystem. Growth potential lies in expanding destination offerings and improving user engagement through personalized services. The absence of direct contact information suggests a focus on automated online service rather than personalized customer support.

Security posture

The current security maturity level is moderate. HTTPS is enforced site-wide, and CSRF tokens protect form submissions, indicating basic security hygiene. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options represents gaps that could expose the site to DNS spoofing or clickjacking attacks. No exposed sensitive data or vulnerable libraries were detected in the provided content. The lack of a public incident response or vulnerability disclosure policy limits transparency and readiness for security incidents. GDPR compliance is supported by a detailed privacy policy, but cookie consent mechanisms are missing, which could be a compliance risk. Overall, the security culture appears functional but could be enhanced with additional controls and transparency.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Add a visible cookie consent banner to comply with GDPR and ePrivacy regulations.
  4. Publish a clear security policy and incident response information to improve transparency and trust.
  5. Consider adding a vulnerability disclosure program or security.txt file to facilitate responsible reporting.

Technical notes

Notes

The website is built on a modern Laravel Livewire framework with Alpine.js for frontend interactivity, indicating a reactive and dynamic user experience. JavaScript is modularized using ES modules, and CSS is loaded via preloads for performance optimization. Hosting is managed through Amazon Registrar, suggesting reliable cloud infrastructure. The site is mobile responsive and accessible, with semantic HTML and ARIA labels where appropriate. Performance is moderate, with room for improvement in caching and asset optimization. No CMS like WordPress or Joomla is detected, indicating a custom-built solution. The technical debt appears low, but security enhancements and cookie management are areas for modernization.
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.
