Security score

Risk levelMedium

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

Optigrün international AG is a well-established European leader in green roofing and roof garden solutions, boasting 50 years of expertise. The company offers a comprehensive range of innovative products and services aimed at enhancing urban ecological balance and sustainability. Their target audience includes architects, project planners, and specialized firms seeking professional green roof systems and consulting services. Technically, the website is built on TYPO3 CMS with Bootstrap framework, incorporating modern analytics and bot protection tools such as Matomo and Google reCAPTCHA. The site demonstrates good mobile optimization, accessibility, and SEO practices. Security-wise, HTTPS is enforced and cookie consent mechanisms are in place, though explicit security policies and vulnerability disclosures are absent, suggesting room for improvement. Overall, the website is professional, trustworthy, and compliant with GDPR, but the lack of WHOIS data and domain registration transparency slightly reduces trust from a domain legitimacy perspective.

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

7 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. 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
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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
  • 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 holds a strong market position as a pioneer in green roof technology in Europe, leveraging decades of experience and a broad partner network including EKROST s.r.o. Their business model focuses on B2B sales and project support, targeting environmentally conscious urban developers and construction professionals. Revenue streams likely include product sales, installation services, and consulting. The multilingual website and international domain variants indicate a strategy for broad European market penetration. The partnership ecosystem and detailed product offerings reflect a mature and specialized operation with growth potential in sustainable urban infrastructure.

Security posture

The website exhibits a moderate to good security posture with HTTPS enforcement, cookie consent, and bot protection via Google reCAPTCHA. However, the absence of security headers, explicit security policies, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in security maturity. No vulnerabilities or exposed sensitive data were detected in the content. The site would benefit from publishing a security policy, implementing security headers, and providing clear incident response channels to enhance trust and compliance, especially under GDPR and NIS2 frameworks.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against common web attacks.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  4. Regularly audit and update third-party scripts and libraries to mitigate risks from vulnerable components.
  5. Enhance domain registration transparency by ensuring WHOIS data is complete and publicly available to improve trustworthiness.

Technical notes

Notes

The website is built on a stable and mature CMS platform (TYPO3) combined with Bootstrap for responsive design. It uses Matomo for privacy-conscious analytics and Google reCAPTCHA for spam and bot mitigation. The site loads a variety of optimized images and uses modern HTML5 and CSS3 features. Performance is moderate, with room for improvement in loading speed and caching strategies. Accessibility features such as skip links and ARIA roles are present, supporting usability. SEO is well addressed with meta tags and canonical URLs. The technical stack is modern but could benefit from enhanced security configurations and performance optimizations.
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.
