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

The Helmholtz-Zentrum Dresden-Rossendorf (HZDR) is a prominent German research center specializing in energy, health, and matter sciences. As a member of the Helmholtz Association, it operates multiple research sites and user facilities, serving both internal and external scientific communities. The website reflects a well-structured, professional institution with a strong emphasis on scientific collaboration and technology transfer. The target audience includes researchers, students, industry partners, and the general public interested in scientific advancements. Technically, the site employs modern web technologies such as React and Astro, ensuring good mobile optimization and accessibility. However, there is room for improvement in privacy compliance and security transparency, as explicit privacy and cookie policies are not found, and security headers are not evident. Overall, the site demonstrates high business credibility and content quality, supporting its position as a reputable research institution.

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

5 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 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';…

  3. 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

HZDR holds a strong market position as a large-scale research center within Germany's Helmholtz Association. Its business model is non-profit, funded by government and sponsors, focusing on cutting-edge research and providing access to advanced user facilities. The institution benefits from strategic partnerships and international collaborations, enhancing its research impact. The website's content and linked domains indicate active engagement in technology transfer, education, and public outreach. Growth indicators include future projects and innovation labs. The partnership ecosystem includes other Helmholtz institutes and regional innovation platforms. The organization's operations are transparent, with clear contact information and social media presence, reinforcing trust and stakeholder engagement.

Security posture

The website's security posture is moderate. HTTPS is enforced, and no sensitive data is exposed in the HTML content. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces the overall security robustness. No vulnerability disclosure policy or security.txt file is present, limiting transparency for security researchers. Forms appear standard but lack explicit security policy references. The site does not show signs of vulnerable libraries or exposed credentials. Incident response contact channels are not provided, which could hinder timely handling of security incidents. Enhancing security headers, publishing a security policy, and implementing a vulnerability disclosure program would significantly improve the security maturity.

Recommendations

  1. Publish explicit privacy and cookie policies linked prominently on the website.
  2. Implement a cookie consent mechanism to comply with GDPR and user privacy expectations.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Create and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Provide incident response contact information, such as security@ or abuse@ email addresses, to improve security communication.

Notes

The website uses a modern technology stack including React components rendered via the Astro framework, with CSS and JavaScript assets well organized. The CMS appears custom-built with versioned assets indicating ongoing maintenance. Performance is moderate, with responsive design and accessibility features implemented. SEO is supported by proper meta tags and Open Graph data. No major technical debt or deprecated technologies are evident. Opportunities exist to improve performance by optimizing asset delivery and enhancing security configurations. The hosting provider is not explicitly identified, but DNS servers indicate institutional hosting consistent with a research center. Overall, the technical infrastructure supports the business goals effectively.
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.
