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

7 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

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 holds a solid market position as a specialized engineering service provider with a diversified portfolio across multiple sectors such as wind energy, civil engineering, and environmental technology. Their business model focuses on delivering engineering consulting and proprietary products for vibration and noise control. The website's content and references to projects and clients demonstrate a credible and professional operation. The presence of a blog and events indicates active engagement with the industry community. Partnerships and references to external domains suggest a collaborative ecosystem. The company targets industrial clients requiring specialized engineering solutions, positioning itself as a trusted expert in its niche.

Security posture

The website demonstrates a good security baseline with HTTPS enabled and no visible exposure of sensitive data. Integration of Google Tag Manager is handled appropriately, though the presence of additional security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security is not confirmed and recommended for enhancement. No vulnerability disclosure or incident response contacts are found, which could be improved to strengthen security transparency. The site does not appear to be behind a WAF or security challenge, allowing full content access. Overall, the security posture is solid but could benefit from implementing additional HTTP security headers and formal vulnerability disclosure mechanisms.

Recommendations

  1. Implement and verify HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Establish a publicly accessible vulnerability disclosure policy or security.txt file to improve transparency and facilitate responsible reporting.
  3. Add explicit incident response contact channels such as security@ or abuse@ email addresses to support security incident handling.
  4. Regularly audit third-party scripts and dependencies to mitigate risks from vulnerable libraries or tracking tools.
  5. Enhance accessibility features and conduct periodic performance optimizations to maintain excellent user experience across devices.

Technical notes

Notes

The website is built on TYPO3 CMS with Bootstrap and jQuery frameworks, indicating a modern and maintainable technology stack. Hosting is managed via onfusic.de nameservers, suggesting a professional hosting environment. The site is mobile optimized with responsive design and good accessibility practices. SEO is well addressed with meta tags, canonical links, and hreflang attributes for multilingual support. Performance is moderate, with some room for optimization. The integration of Google Tag Manager enables analytics and marketing capabilities. No critical technical debt or outdated technologies are evident, but security header implementation and formal vulnerability disclosure are areas for improvement.
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.
