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

Drausy GmbH operates as a specialized provider of biological water treatment and odor control solutions, focusing on sustainable and environmentally friendly technologies for water, wastewater, and soil treatment. The company targets municipal water management, environmental technology sectors, and related industries, positioning itself as a niche player with recognized expertise and practical applications demonstrated through expert testimonials and awards. The website reflects a professional and consistent brand image with detailed product information and a user-friendly contact mechanism. Technically, the website employs modern web technologies including Vue.js, Bootstrap, Google Analytics, and reCAPTCHA, ensuring a responsive and interactive user experience. The presence of a cookie consent manager (Klaro) and multi-language support indicates a mature digital infrastructure with attention to privacy compliance. Performance is moderate with good mobile optimization and basic accessibility features. From a security perspective, the site uses HTTPS and implements reCAPTCHA on forms to mitigate spam. However, it lacks explicit security headers and a published security policy or incident response contact, which are recommended for enhanced security posture. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, Drausy GmbH's website presents a trustworthy and professional front with solid business credibility and compliance with GDPR. The domain registration data is partially consistent with the business claims, supporting legitimacy. Strategic improvements in security policies and technical headers would further strengthen the site's security and trustworthiness.

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

3 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
    • High

      Weak SSL Key Length

      SSL certificate uses 384-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Drausy GmbH operates in the environmental technology sector with a focus on biological water and wastewater treatment solutions. The company leverages sustainable methods to enhance water quality and reduce odors, targeting municipal and industrial clients. Its business model is primarily B2B and B2G, offering specialized products and consulting services. The website content and testimonials suggest a well-established market presence with competitive advantages in eco-friendly technology and long-term operational reliability. The company maintains direct customer engagement through detailed contact forms and personalized consultation offers. Growth potential is supported by climate protection and sustainability trends. No explicit partnerships or subsidiaries were identified from the content.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforcement and use of Google reCAPTCHA to protect contact forms. Cookie consent is managed via Klaro, supporting GDPR compliance. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces defense-in-depth. No incident response or vulnerability disclosure information is published, which limits transparency and preparedness. No critical vulnerabilities or exposed sensitive data were found in the analyzed content. Overall, the security posture is adequate for the business type but could be improved by adopting recommended HTTP headers and publishing security policies.

Recommendations

  1. Implement HTTP security headers including Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and trust.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Regularly audit and update third-party libraries and dependencies to mitigate potential vulnerabilities.
  5. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website is built using a modern technology stack including Vue.js for reactive UI components, Bootstrap for responsive design, and Swiper.js for interactive sliders. Google services such as Analytics, reCAPTCHA, and Maps API are integrated for tracking, security, and location features. The CMS appears to be Joomla based on form and URL patterns. Performance is moderate with good mobile optimization and SEO practices including meta tags and structured navigation. The site uses a cookie consent manager (Klaro) with multi-language support, indicating attention to privacy compliance. Technical risks are minimal but could be reduced by adding security headers and improving accessibility compliance.
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.
