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

The website knowh2o.de serves as a specialized knowledge portal dedicated to water management and the water industry, primarily targeting professionals and stakeholders within the German energy and water sectors. It provides educational content and resources to support water management practices. The site is built on a WordPress platform utilizing popular plugins such as Yoast SEO and Elementor, indicating a moderate level of digital maturity and a focus on content presentation and SEO. However, the technical infrastructure shows room for improvement in security and privacy compliance, with no visible privacy or cookie policies and a lack of security headers. The absence of contact information and incident response details limits transparency and trustworthiness. Overall, the website is functional and professionally designed but would benefit from enhanced security measures and compliance documentation to improve its risk posture and user trust.

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

4 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 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';…

  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.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

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

KnowH2O positions itself as a niche information provider within the water management sector in Germany, focusing on knowledge dissemination rather than commercial transactions. Its business model revolves around providing educational and informational content, likely monetized indirectly through partnerships or memberships, though no explicit commercial mechanisms were detected. The portal targets industry professionals and stakeholders, aiming to be a trusted resource in the water and energy sectors. The lack of visible certifications or trust indicators suggests a need to strengthen credibility through formal recognitions or partnerships. The hosting and domain registration appear standard, with no privacy protection, supporting legitimacy but lacking detailed registrant information.

Security posture

The website currently exhibits a basic security posture. HTTPS is presumed but not explicitly confirmed in the data; no security headers such as Content-Security-Policy or X-Frame-Options were detected, which are critical for mitigating common web vulnerabilities. The absence of privacy and cookie policies indicates potential compliance gaps with GDPR and other data protection regulations. No incident response or vulnerability disclosure information is provided, limiting the site's readiness to handle security incidents. The use of popular CMS and plugins necessitates regular updates to avoid vulnerabilities. Overall, the security maturity is low to moderate, with significant room for improvement to meet industry best practices and regulatory requirements.

Recommendations

  1. Implement and publicly display a comprehensive privacy policy and cookie consent mechanism to ensure GDPR compliance.
  2. Configure and enforce security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common attacks.
  3. Add clear contact information including emails and phone numbers to improve transparency and user trust.
  4. Establish and publish an incident response plan and vulnerability disclosure policy to demonstrate security readiness.
  5. Regularly update all CMS components and plugins to mitigate risks from known vulnerabilities.

Technical notes

Notes

The website is built on WordPress with Elementor and Yoast SEO plugins, indicating a modern and flexible content management approach. The use of LearnDash LMS suggests educational content delivery capabilities. Hosting appears to be managed via your-server.de and related nameservers, typical for small to medium-sized German websites. Performance is moderate with good mobile optimization and basic accessibility features. SEO optimization is supported by Yoast SEO plugin, enhancing search engine visibility. However, the absence of advanced security configurations and privacy compliance features indicates technical debt and potential risks. Opportunities exist to modernize security infrastructure and improve compliance to align with best practices.
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.
