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. 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 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

  • Email security: did not complete in this scan.
  • DNS health: did not complete in this scan.
  • 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 B2B customers in manufacturing sectors requiring precision injection molding technology. Their business model focuses on supplying high-quality, customizable hot and cold runner systems, complemented by digital tools like the CADHOC system designer and augmented reality support. The presence of certifications such as ISO 9001 and ISO 14001 reinforces their commitment to quality and environmental standards. Their market position as a technology leader is supported by extensive product offerings and training seminars. The website's multilingual support and global contact points suggest an international customer base.

Security posture

The website demonstrates a mature security posture with HTTPS and no exposed sensitive data. However, the absence of key security headers and a formal security policy or incident response contact reduces overall security maturity. The use of self-hosted analytics indicates privacy-conscious tracking, but the lack of a cookie consent banner may pose compliance risks under GDPR. No vulnerabilities or suspicious scripts were detected in the provided HTML content. Enhancing security headers and publishing incident response information would strengthen trust and compliance.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Add a visible cookie consent mechanism to comply with GDPR and inform users about tracking.
  3. Publish a dedicated security policy and provide incident response contact details (e.g., security@ or abuse@ email).
  4. Regularly audit third-party scripts and update libraries to mitigate potential vulnerabilities.
  5. Enhance accessibility features and mobile optimization to improve user experience and SEO.

Technical notes

Notes

The website is built on the Contao Open Source CMS platform, leveraging jQuery and related UI libraries for interactivity and navigation. The presence of mmenu.js and colorbox.js indicates a focus on responsive menus and media display. The site uses a custom analytics solution hosted on a subdomain, avoiding reliance on major third-party trackers. Performance is moderate, with optimized images and responsive design supporting mobile users. Accessibility features are basic but present, including skip navigation links and ARIA attributes. SEO is supported by meta tags, Open Graph data, and structured JSON-LD. Technical debt appears low, but improvements in security headers and privacy mechanisms are recommended to modernize the security posture and 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.
