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

Hülskens Barleben GmbH & Co. KG is a medium-sized German company specializing in the extraction and supply of construction materials, primarily sand and gravel, for public and private building projects. The company operates multiple sites and offers a comprehensive product range including standard and specialized aggregates. Their business model focuses on providing a full supply chain solution from extraction to delivery via truck and ship, positioning them as a reliable regional partner within the construction materials industry. The website reflects a professional and consistent brand presence with clear navigation and relevant content tailored to construction professionals and clients. Technically, the website is built on the Contao Open Source CMS platform, utilizing common JavaScript libraries such as jQuery and Colorbox for UI enhancements. The site demonstrates good mobile optimization and basic accessibility features, with moderate performance. SEO practices are adequately implemented through meta tags and structured navigation. The absence of heavy analytics or tracking scripts suggests a privacy-conscious approach. From a security perspective, the site enforces HTTPS and includes a cookie consent mechanism compliant with GDPR. However, it lacks explicit security headers and a dedicated security policy or incident response contact, which are areas for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. WHOIS data is consistent with the business identity, supporting domain legitimacy. Overall, the website presents a trustworthy and professional digital presence for Hülskens Barleben GmbH & Co. KG, with solid business credibility and privacy compliance. Strategic enhancements in security headers and incident response transparency would further strengthen their security posture.

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. 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

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

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

Hülskens Barleben operates in the manufacturing and transportation sectors, focusing on supplying mineral raw materials for construction. Their competitive advantage lies in their integrated supply chain and regional presence along major rivers in Germany. The company targets construction firms and infrastructure projects, offering both standard and specialized products. The business benefits from being part of the larger Hülskens Firmenverband, which provides brand strength and operational support. The downloadable product brochures and multiple site locations indicate a mature operation with growth potential. The website's linkage to related domains suggests a broader ecosystem supporting geology and raw material information, enhancing customer engagement and trust.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS and GDPR-compliant cookie consent. The lack of advanced security headers and absence of a published security policy or incident response contact are notable gaps. No third-party analytics or tracking scripts reduce privacy risks but also limit behavioral insights. The site does not expose sensitive data or show signs of vulnerabilities in the HTML content. Overall, the security posture is adequate for the business type but could be improved by implementing security headers, publishing a security policy, and establishing clear incident response channels.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page outlining security practices and provide a contact channel for incident reporting to improve transparency and trust.
  3. Regularly update all third-party libraries and CMS components to mitigate risks from known vulnerabilities.
  4. Enhance accessibility features to meet higher standards, improving usability for all users.
  5. Consider integrating privacy-friendly analytics to gain user insights while maintaining GDPR compliance.

Technical notes

Notes

The website is built on the Contao CMS platform, leveraging jQuery and related UI libraries for interactive elements such as sliders and modals. The codebase includes CSS preprocessor files (SCSS, LESS) indicating a modern front-end development approach. Performance is moderate, with multiple CSS and JS files loaded but no heavy third-party scripts detected. Mobile optimization is good, supported by viewport meta tags and responsive design elements. SEO is supported by meta descriptions, structured navigation, and schema.org markup. The site lacks advanced security headers but uses HTTPS correctly. Hosting provider details are not explicitly available from the content. Overall, the technical infrastructure is stable and suitable for the business needs but could benefit from performance optimizations and enhanced security configurations.
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.
