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

8 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. 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)

      • 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 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';…

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 · 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 company operates in the transportation sector focusing on environmental technology solutions for wet waste disposal. Their business model combines manufacturing, service, and training offerings, targeting a niche industrial market. The presence of certifications and compliance pages indicates a mature operational framework. Social media engagement and a dedicated shop subdomain suggest active customer engagement and diversified revenue streams. Partnerships with technology networks like It's OWL enhance their innovation ecosystem. The company’s medium size and family ownership imply agility and specialized expertise, positioning them well against competitors in their niche.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, cookie consent management, and visible ISO certifications. However, the absence of explicit security headers and lack of an incident response or vulnerability disclosure policy are gaps that could be addressed to enhance security posture. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is strong with clear policies and consent mechanisms. The company should consider publishing dedicated security contact channels and a vulnerability disclosure policy to improve transparency and incident readiness.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish an incident response contact email (e.g., security@mueller-umwelt.de) to facilitate vulnerability reporting.
  3. Develop and publish a vulnerability disclosure policy or security.txt file to improve transparency and trust.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance website performance monitoring and optimize loading times for better user experience.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust and widely used content management system, leveraging modern JavaScript libraries such as Flickity for UI components and CookieFirst for consent management. The site is mobile-optimized with responsive design and accessibility features. Performance is moderate, with compressed CSS and JS assets. SEO is well addressed with proper meta tags, Open Graph, and JSON-LD structured data. Hosting details are not explicit, but no performance or uptime issues were detected. Opportunities exist to improve security headers and incident response readiness to reduce technical risks.
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.
