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

6 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"

    • 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
  • 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

Troester operates in the manufacturing sector, focusing on extrusion machinery for rubber and plastics industries. Its business model is B2B, serving industrial manufacturers globally. The company leverages its long heritage and German engineering reputation to maintain competitive advantages. Revenue streams likely include machinery sales, service contracts, digital solutions, and spare parts. The presence of partner domains like troester-parts.de and x-compound.ch indicates a strategic ecosystem supporting product lifecycle and specialized technology. The company targets industrial clients seeking high-quality, durable extrusion solutions. Growth indicators include recent management changes and active event participation. The website's professional content and structured data enhance market visibility and customer engagement.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS, absence of exposed sensitive information, and use of privacy-respecting analytics (Matomo). However, it lacks explicit cookie consent mechanisms and published security policies or incident response contacts, which are important for GDPR compliance and user trust. No vulnerable libraries or security headers beyond basic ones were detected, suggesting room for improvement in security hardening. The absence of a vulnerability disclosure policy or security.txt file indicates limited transparency in security incident handling. Overall, the security posture is solid but could be enhanced by adopting best practices in privacy and incident response communication.

Recommendations

  1. Implement a clear cookie consent banner to comply with GDPR and enhance user trust.
  2. Publish a detailed security policy and incident response contact information on the website.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and Strict-Transport-Security.
  4. Consider creating a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly review and update privacy and security practices to maintain compliance and improve transparency.

Technical notes

Notes

The website is built on WordPress using a custom theme developed by B&B Markenagentur. It employs modern HTML5, CSS3, and JavaScript technologies, including lazy loading for images and video backgrounds for enhanced user experience. Hosting is managed via Deutsche Telekom name servers, indicating reliable infrastructure. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by comprehensive meta tags and structured JSON-LD data. Analytics are handled by Matomo, favoring privacy. Technical risks are minimal, but the site could benefit from enhanced security headers and cookie management to reduce compliance risks and improve security posture.
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.
