Risk levelMedium

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

ÖKO-HAUS GmbH is a small German company specializing in photovoltaic systems, battery storage solutions, and system services primarily serving the Unterallgäu region. The company positions itself as a regional expert in renewable energy solutions, targeting both residential and commercial customers interested in sustainable energy technologies. Their website is professionally designed using WordPress with the Divi theme, incorporating SEO best practices and cookie consent mechanisms to comply with privacy regulations. However, the absence of a visible privacy policy and terms of service pages indicates room for improvement in compliance transparency. From a security perspective, the site uses HTTPS and cookie consent but lacks visible security headers and incident response information, which could be enhanced to strengthen its security posture. The WHOIS data is missing or indicates the domain may not be registered, which is inconsistent with the active website presence and lowers trustworthiness from a domain registration standpoint. Overall, the website is functional, informative, and well-structured but would benefit from improved compliance documentation and security hardening.

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. 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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 company operates in the energy sector with a focus on renewable energy technologies, specifically photovoltaic and battery storage systems. Its business model likely includes direct sales, installation, and maintenance services for photovoltaic systems. The target audience includes homeowners, businesses, and agricultural clients in the Unterallgäu region. The company leverages social media platforms such as Facebook and YouTube for marketing and customer engagement. The website's SEO and content quality suggest a moderate digital maturity level. The lack of WHOIS data and privacy policy may impact customer trust and regulatory compliance. There is no evidence of partnerships or subsidiaries from the data provided. The company appears to be a standalone small business with a regional market focus.

Security posture

The website enforces HTTPS, which is a fundamental security requirement. It implements a cookie consent mechanism via Borlabs Cookie, indicating awareness of privacy regulations. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security posture. No vulnerability disclosure or incident response information is available, which limits the company's ability to manage security incidents effectively. The missing WHOIS data raises concerns about domain legitimacy and ownership transparency. No exposed sensitive data or vulnerable libraries were detected in the provided content. Security best practices should be enhanced by adding security headers, publishing a privacy policy and terms of service, and establishing a vulnerability disclosure process.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve compliance and customer trust.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a security.txt file and incident response contact information to facilitate vulnerability reporting and incident management.
  4. Verify and update WHOIS domain registration information to ensure transparency and legitimacy.
  5. Conduct regular security audits of plugins and themes to identify and mitigate vulnerabilities.

Technical notes

Notes

The website is built on WordPress using the Divi theme, a popular and flexible CMS platform. It uses Rank Math SEO for search engine optimization and Borlabs Cookie for cookie consent management, indicating a focus on SEO and privacy compliance. The site loads Google Fonts and includes Google Tag Manager for analytics and marketing tracking. Performance appears moderate with good mobile optimization and basic accessibility features. The site lacks advanced security headers and detailed technical metadata related to hosting or CDN providers. There is no evidence of outdated or vulnerable libraries in the provided content. Overall, the technical infrastructure is standard for a small business website 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.
