0–100, higher is better. How it is calculated

CAL GmbH & Co. KG is a German-based chemical analysis service provider established in 1984. The company specializes in precise chemical analyses for soil, water, dietary supplements, and cosmetics, targeting businesses requiring quality assurance in these sectors. Their website is professionally designed using the Contao CMS platform and modern JavaScript libraries, providing a good user experience with clear navigation and relevant content in German. The technical infrastructure is moderate in performance with good mobile optimization but lacks advanced security headers and cookie consent mechanisms. Security posture is basic with HTTPS enabled but missing several best practices such as security policies and incident response contacts. WHOIS data confirms the domain's legitimacy and consistency with the business history. Overall, the website is trustworthy and functional but could improve in privacy compliance and security transparency.

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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319

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 operates as a specialized laboratory service provider in the chemical analysis sector, serving industries such as construction, agriculture, food supplements, and cosmetics. Their market position is supported by decades of experience and interdisciplinary teams. The business model focuses on service and consulting, with key revenue streams likely from laboratory testing and analysis contracts. The website indicates a small-sized company with a clear focus on quality and customer service. No evident partnerships or subsidiaries are listed. The absence of social media and advanced marketing tools suggests a traditional business approach. Growth indicators include a diverse service portfolio and ongoing expertise expansion.

Security posture

The website employs HTTPS, ensuring encrypted communication. However, it lacks critical security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options, which are important for mitigating common web vulnerabilities. No visible security or incident response policies are published, and no dedicated security contact channels are provided. The absence of a cookie consent mechanism indicates partial GDPR compliance. No known vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is basic and would benefit from enhancements to align with best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive security headers to enhance protection against common web attacks.
  2. Add a cookie consent banner and improve privacy policy details to ensure GDPR compliance.
  3. Publish a clear security policy and incident response plan with dedicated contact channels.
  4. Regularly audit and update third-party libraries to avoid vulnerabilities.
  5. Enhance website accessibility and SEO further to improve user experience and reach.

Technical notes

Notes

The website is built on the Contao CMS platform, utilizing modern JavaScript libraries such as jQuery, Slick Slider, and AOS for animations and UI enhancements. The site is mobile optimized with responsive design elements and good navigation clarity. Performance is moderate, with some potential for optimization in loading speed. The HTML structure is valid and SEO-friendly with appropriate meta tags. However, the lack of advanced security headers and cookie consent mechanisms indicates technical debt in security and privacy compliance. Hosting provider details are not explicitly identified. Overall, the technical implementation supports the business needs but requires improvements in security and privacy features.
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.
