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

4 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 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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

The company targets industrial clients in manufacturing, transportation, and energy sectors, leveraging its engineering expertise and multiple subsidiaries to maintain a competitive market position. The business model focuses on delivering engineering projects with cost and schedule certainty, supported by a comprehensive service offering from planning to assembly. The presence of multiple subsidiaries suggests a diversified operational structure and potential for cross-selling services. The website content and structure indicate a mature digital presence with emphasis on transparency and compliance, which supports customer trust and regulatory adherence.

Security posture

The security maturity level is moderate, with HTTPS enforced and cookie consent managed via Cookiebot. The use of Matomo analytics aligns with privacy-friendly data collection practices. However, the absence of explicit security policies, incident response contacts, and security headers represents gaps that could be addressed to enhance security posture. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The company would benefit from publishing a security policy and implementing security headers to mitigate common web risks and improve trustworthiness.

Recommendations

  1. Implement comprehensive security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all visitors.
  5. Regularly audit and update third-party libraries and CMS components to mitigate vulnerabilities.

Technical notes

Notes

The website is built on TYPO3 CMS with integration of modern JavaScript libraries like Swiper, AOS, and Slick Carousel, providing dynamic and responsive UI elements. Hosting and DNS are managed via Cloudflare, ensuring reliable performance and security benefits. The site uses Matomo for analytics, favoring privacy over third-party trackers. Cookie consent is handled by Cookiebot, ensuring GDPR compliance. Performance is moderate with room for optimization, especially in accessibility and security header implementation. The technical stack is modern and well-maintained, supporting the company's digital maturity and operational needs.
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.
