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

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

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 · 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

Business profile

The ifeu gGmbH holds a strong market position as a leading ecological research institute in Germany with international reach. Its business model is focused on non-profit research and consulting in sustainability and environmental topics, targeting government bodies, research institutions, and industry stakeholders. The institute's competitive advantage lies in its long-standing experience, multidisciplinary team, and comprehensive project portfolio. Revenue streams likely come from research grants, consulting contracts, and commissioned projects. The website's detailed project descriptions and thematic focus areas indicate a mature partnership ecosystem and a strategic approach to addressing key sustainability challenges. The presence on multiple social media platforms and a podcast further supports outreach and stakeholder engagement.

Security posture

The website demonstrates a mature security posture with enforced HTTPS and privacy-conscious analytics configuration (Matomo with DoNotTrack and disabled cookies). No sensitive data is exposed in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy and lack of publicly available security or incident response policies represent areas for enhancement. There is no visible vulnerability disclosure or security.txt file, which could improve transparency and trust. Overall, the security measures are adequate for the website's purpose but could be strengthened to align with best practices and compliance frameworks.

Recommendations

  1. Implement standard security headers (CSP, X-Content-Type-Options, X-Frame-Options) to enhance protection against common web attacks.
  2. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting and improve trust.
  3. Add a cookie consent mechanism to comply fully with EU cookie regulations and enhance user privacy transparency.
  4. Provide explicit information about incident response procedures or security contacts to improve organizational transparency.
  5. Regularly audit and update third-party libraries and CMS components to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on TYPO3 CMS, a robust open-source content management system widely used in Germany. It uses modern JavaScript libraries including jQuery 3.6.0, Slick Slider for carousels, FontAwesome for icons, and Magnific Popup for modals. Matomo analytics is used for privacy-respecting user tracking. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, likely due to rich media content and multiple scripts. The site has proper meta tags for SEO and social sharing (Open Graph and Twitter cards). There is no indication of hosting provider from the HTML content, but DNS nameservers suggest a professional DNS hosting service. Overall, the technical infrastructure is solid with opportunities for performance tuning 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.
