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

Heimvooorteil is a regional initiative focused on promoting energy-efficient home renovations in the Untermain region of Germany. The website serves as a platform to inform homeowners about energy consulting, funding, financing options, and connects them with local professionals for services such as heat pump and photovoltaic installations. Supported by local government entities and financial institutions like Sparkasse Aschaffenburg Miltenberg, the initiative positions itself as a trusted regional resource for sustainable energy solutions. Technically, the website is built on a modern Laravel framework with Livewire components, styled using Tailwind CSS, and integrates Mapbox for geolocation services. It employs privacy-focused analytics (Fathom) and implements a cookie consent mechanism compliant with GDPR. The site is mobile-optimized, accessible, and demonstrates good SEO practices. From a security perspective, the site uses HTTPS with good SSL configuration and avoids exposing sensitive data. However, it lacks explicit security headers and formal security policies or vulnerability disclosure mechanisms. The contact form collects personal data with explicit consent, aligning with privacy regulations. Overall, the website presents a professional, trustworthy, and user-friendly platform with a strong regional focus. Strategic improvements in security headers and formal security documentation could enhance its security posture further.

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

6 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 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';…

  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

Heimvooorteil operates as a small but important regional energy sector initiative, leveraging partnerships with local governments, financial institutions, and trade organizations. Its business model centers on providing information, consulting, and facilitating connections between homeowners and local service providers. The initiative benefits from strong trust signals through visible endorsements and partnerships. The target audience includes homeowners and residents interested in sustainable energy renovations. The platform's growth potential lies in expanding its network of professionals and increasing user engagement through interactive tools like price calculators and personalized offers.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and privacy-compliant cookie consent. No critical vulnerabilities or exposed sensitive data were detected. However, the absence of security headers such as Content-Security-Policy and lack of a published security policy or incident response contacts indicate room for improvement. There is no evidence of a vulnerability disclosure program or security.txt file. The site’s security culture appears basic but compliant with GDPR requirements for data collection and consent.

Recommendations

  1. Implement standard security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures.
  3. Establish and publish a vulnerability disclosure program, including a security.txt file to facilitate responsible reporting.
  4. Regularly audit third-party libraries and dependencies to ensure no known vulnerabilities are present.
  5. Enhance transparency by providing more detailed business contact information and data retention policies.

Technical notes

Notes

The website uses a modern technology stack with Laravel and Livewire for backend and frontend interactivity, Tailwind CSS for styling, and Mapbox GL JS for map visualizations. It integrates Fathom Analytics for privacy-respecting user tracking. The site is mobile-optimized and accessible, with good SEO metadata and structured data (JSON-LD). Performance is moderate, with some preloading of CSS and JS assets. The use of cookie consent scripts and deferred loading of analytics scripts indicates attention to privacy and performance. No major technical debt or deprecated technologies were detected.
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.
