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

42watt.de is a German energy consulting and service company specializing in sustainable renovation solutions that help customers save up to 80% on energy costs. The website positions the company as an independent advisor offering comprehensive services including planning, implementation, and subsidy management. The target audience primarily consists of homeowners and property owners interested in energy efficiency and sustainability. The company leverages a modern digital infrastructure built on Webflow, integrating multiple analytics and marketing tools such as Google Tag Manager, Microsoft Clarity, PostHog, and Sentry for monitoring and user insights. The website is well-designed, mobile-optimized, and provides a professional user experience, although explicit privacy and terms of service policies are not found in the provided content.

Overall, the site is safe, trustworthy, and compliant with basic cookie consent mechanisms but would benefit from enhanced privacy compliance and security transparency.

NIS2 and GDPR posture

Not assessed

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding rated critical or high. Fix these first.

  1. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 energy-efficient renovation consulting and services. Its business model revolves around independent advice and full-service project management including subsidy processing, targeting environmentally conscious consumers in Germany. The embedded Google reviews and partner references indicate a moderate market position with trust signals. The use of multiple marketing and analytics tools suggests an active digital marketing strategy. However, the absence of explicit contact information and legal policies on the site may limit full business credibility. No parent or subsidiary companies are identified. The company appears to be medium-sized based on website complexity and service scope.

Security posture

The website employs HTTPS with an excellent SSL configuration and integrates advanced monitoring tools like Sentry and PostHog, indicating a proactive approach to error and performance tracking. Cookie consent is implemented, supporting GDPR compliance. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces the overall security hardening. No vulnerability disclosure or incident response information is published, which could hinder rapid response to security incidents. No exposed sensitive data or vulnerable libraries were detected in the provided content. The security score is good but could be improved by adding explicit security policies and headers.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages clearly accessible from the website.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Provide explicit contact information including company emails and phone numbers to improve business credibility and user trust.
  5. Regularly audit and update third-party scripts and analytics tools to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on the Webflow platform, utilizing modern front-end technologies and integrating multiple third-party services for analytics, error monitoring, and marketing automation. The site loads multiple asynchronous scripts from trusted domains, including Google Tag Manager, Microsoft Clarity, PostHog, Sentry, and others. The presence of CMS slider and mirror click attributes from Finsweet indicates advanced UI components. Hosting is likely provided by Webflow, ensuring reliable uptime and performance. Mobile optimization is good with responsive design elements. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic but could be enhanced. Performance is moderate, with potential improvements in script loading optimization.
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.
