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

MTB GmbH operates in the transportation and construction sectors, focusing on railway infrastructure projects. Their competitive advantage lies in their specialization as a general contractor for Deutsche Bahn AG and their digital, precise planning approach. The business model centers on delivering complex infrastructure projects nationwide with a strong emphasis on partnerships and community engagement. Revenue streams likely derive from large-scale construction contracts and specialized engineering services. The company targets infrastructure clients, government agencies, and private sector partners. Growth indicators include recent acquisition of Dammeyer GmbH & Co. KG and recognition as a Top 100 Innovator for 2025. The partnership ecosystem is broad, involving multiple regional and industry partners, enhancing operational capabilities and market reach.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and cookie consent mechanisms in place, supporting GDPR compliance. No critical vulnerabilities or exposed sensitive data were detected in the content. However, the lack of security headers such as Content-Security-Policy and absence of a published security policy or incident response contact reduces the overall security posture. There is no evidence of a vulnerability disclosure program or security.txt file, which are best practices for transparency and incident management. The company should consider implementing these to improve readiness and trust. Overall, the security culture appears basic but functional, with room for strategic enhancements.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear security policy and provide dedicated incident response contact channels (e.g., security@ or abuse@ email addresses).
  3. Establish a vulnerability disclosure program and consider adding a security.txt file to enhance transparency and community trust.
  4. Conduct regular security audits of third-party plugins and scripts to identify and remediate vulnerabilities promptly.
  5. Enhance website accessibility features to comply with standards and improve user experience for all visitors.

Technical notes

Notes

The website is built on WordPress CMS with popular plugins such as Yoast SEO for search engine optimization and WPBakery Page Builder for content management. The technology stack includes standard web technologies: HTML5, CSS, JavaScript, and PHP. The site uses modern fonts and responsive design techniques, ensuring good mobile optimization. Performance is moderate, with some caching and minification evident. Hosting provider details are not explicitly identified. The site lacks advanced frameworks but is well-structured and SEO-friendly. Technical risks include potential plugin vulnerabilities and missing security headers. Opportunities exist to modernize security practices and improve accessibility compliance.
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.
