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

Heraeus Group is a globally recognized, family-owned technology company headquartered in Hanau, Germany, with a rich history spanning over 350 years. The company specializes in advanced materials and innovative technology solutions across multiple sectors including metals and recycling, healthcare, semiconductor and electronics, and industrial applications. Their business model focuses on providing customized, technology-driven solutions to industrial and healthcare customers worldwide. The website reflects a mature digital presence with comprehensive content, strong branding, and a clear focus on sustainability and innovation. Technically, the website is built on modern frameworks such as Nuxt.js and Vue.js, supported by a Magnolia CMS backend. It employs industry-standard analytics and consent management tools, ensuring compliance with privacy regulations like GDPR. The site is mobile-optimized, accessible, and SEO-friendly, providing a positive user experience. From a security perspective, the site enforces HTTPS and uses cookie consent mechanisms, but lacks explicit security headers such as Content-Security-Policy and X-Frame-Options. No vulnerabilities or exposed sensitive data were detected. The absence of WHOIS data for the domain is a notable concern, potentially indicating privacy protection or registry issues, which slightly impacts trustworthiness. Overall, Heraeus Group's website demonstrates a strong business and technical foundation with good security practices, though improvements in security header implementation and transparency in domain registration are recommended to enhance trust and compliance.

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

2 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 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

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

Heraeus Group holds a strong market position as a diversified technology leader with a focus on materials science and innovation. Their competitive advantage lies in their extensive expertise, global footprint, and diversified portfolio spanning metals, healthcare, electronics, and industrial sectors. The company targets industrial clients, healthcare providers, and technology partners, leveraging a B2B business model. Growth indicators include active innovation programs, acquisitions, and sustainability initiatives. The partnership ecosystem includes subsidiaries and specialized business units, enhancing their market reach and technological capabilities. Strategic observations highlight a focus on sustainability, innovation culture, and digital transformation to maintain competitiveness.

Security posture

The security posture of the Heraeus website is solid with mandatory HTTPS encryption and cookie consent management in place, reflecting compliance with privacy regulations. However, the lack of explicit security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement to mitigate risks like clickjacking and cross-site scripting. No direct incident response or security policy information is publicly available, which could be enhanced to demonstrate readiness and transparency. No vulnerabilities or exposed sensitive data were identified, indicating good operational security hygiene. The missing WHOIS data introduces some uncertainty regarding domain registration transparency, which should be addressed to strengthen trust.

Recommendations

  1. Implement and enforce Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers to enhance security.
  2. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  3. Enhance domain registration transparency by ensuring WHOIS data is publicly available or justified with privacy protection.
  4. Consider adding direct company contact emails and phone numbers to improve user trust and communication.
  5. Regularly audit third-party scripts and tracking tools to ensure no vulnerabilities or privacy issues arise.

Technical notes

Notes

The website leverages a modern technology stack including Nuxt.js and Vue.js frameworks, supported by Magnolia CMS for content management. It integrates Google Tag Manager and CookieFirst for analytics and consent management, with conditional Baidu analytics for Chinese language pages. The site is well-optimized for mobile devices and accessibility, with good SEO practices evident in meta tags and structured data. Performance is moderate, with potential for improvement in loading speed. The technical infrastructure supports a professional and scalable digital presence, though security header implementation and hosting provider transparency could be enhanced to reduce technical risks.
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.
