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

The Berliner Regenwasseragentur is a government-affiliated initiative focused on decentralized rainwater management in Berlin. It serves as a service point providing information, consultation, and educational events to citizens and businesses interested in sustainable water use. The website positions itself as a niche environmental service with strong ties to local government entities, including the Senatsverwaltung für Umwelt, Verkehr und Klimaschutz and Berliner Wasserbetriebe. The business model is primarily informational and supportive, targeting environmental sustainability and urban water management. Technically, the website is built on WordPress, leveraging Yoast SEO Premium for search optimization and Cookiebot for GDPR-compliant cookie consent management. Hosting is provided via Versatel, with a moderate performance profile and good mobile optimization. The site uses structured data (JSON-LD) to enhance SEO and provide clear organizational information. Analytics are conducted via Etracker, with moderate user tracking and transparent cookie policies. From a security perspective, the site enforces HTTPS and employs cookie consent mechanisms, but lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or suspicious content were detected. Privacy compliance is strong, with detailed cookie information and opt-in consent. However, the absence of terms of service and security policies indicates room for improvement. Overall, the site is trustworthy, professional, and well-aligned with its public service mission. Strategic recommendations include enabling DNSSEC, publishing security and incident response policies, and adding a vulnerability disclosure mechanism to enhance transparency and security posture.

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

The Berliner Regenwasseragentur operates within the government and environmental sectors, focusing on sustainable urban water management. Its competitive advantage lies in its official backing and specialized focus on decentralized rainwater use in Berlin. Revenue streams are likely public funding and grants, with no direct commercial transactions evident. The target customers are local citizens, businesses, and stakeholders interested in environmental sustainability. Growth indicators include ongoing educational events and digital presence enhancements. Partnerships with government agencies and water utilities strengthen its ecosystem. The organization maintains a clear public service orientation with a niche market position.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforcement and GDPR-compliant cookie management. The use of Cookiebot and Etracker indicates awareness of privacy and analytics best practices. However, the lack of explicit security headers, published security policies, and incident response contacts suggests gaps in comprehensive security governance. No exposed sensitive data or vulnerable libraries were detected. The site would benefit from formalizing security documentation and enabling DNSSEC to mitigate DNS spoofing risks. Overall, the security posture is adequate for a public informational site but can be enhanced to meet higher standards.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a formal security policy and incident response contact information on the website.
  3. Implement additional HTTP security headers such as X-Frame-Options and X-Content-Type-Options.
  4. Establish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on a WordPress CMS platform with Yoast SEO Premium plugin for SEO optimization and Cookiebot for cookie consent management. Hosting is via Versatel, indicated by the nameservers. The site uses modern web standards, including responsive design and structured data (JSON-LD) for SEO. Performance is moderate, with some caching and minification evident. Analytics are implemented via Etracker, using cookies and pixel tracking. The technical stack is well-maintained but could benefit from additional security hardening and performance tuning. No deprecated or vulnerable libraries were detected in the HTML content.
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.
