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

mr.sol Alternative Energie und Heizungstechnik is a small, specialized service provider based in Germany focusing on renewable energy heating solutions including biomass heating, solar thermal systems, and sanitary installations. Founded in 1994, the company has a strong local presence in the Leipzig and Markranstädt region, offering expert services in modern heating technologies such as pellet and wood heating systems. The website reflects a professional and consistent brand image with clear contact information and certifications that enhance trust. Technically, the website is built on WordPress using modern plugins and themes such as WPBakery Page Builder and Yoast SEO, indicating a moderate level of digital maturity. The site is mobile optimized and performs moderately well, though there is room for improvement in accessibility and performance optimization. SEO practices are adequately implemented with proper meta tags and structured data. From a security perspective, the site uses HTTPS and avoids exposing sensitive data, but lacks important security headers and a vulnerability disclosure policy. The contact forms do not have active CAPTCHA protection, which could expose the site to spam. Privacy compliance is basic, with a privacy policy present but no cookie consent mechanism or terms of service. No social media or analytics tracking is evident, which limits user tracking but also reduces marketing insights. Overall, the website is trustworthy and professional with a good business focus but could improve its security posture and privacy compliance to better protect users and enhance credibility.

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. 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

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Security headers

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

mr.sol operates in the renewable energy sector, targeting residential and commercial customers interested in sustainable heating solutions. Their competitive advantage lies in their long-standing experience since 1994 and specialization in biomass and solar heating technologies. The business model is service-oriented, focusing on installation, maintenance, and consultation. Revenue streams likely come from project contracts and service agreements. The company maintains a localized market presence with certifications that support quality assurance. There is no evidence of extensive partnerships or subsidiaries. Growth indicators include recent website updates and certifications. The company could benefit from expanding digital marketing and enhancing online presence through social media and analytics.

Security posture

The current security maturity level is moderate. The website enforces HTTPS, which is essential, but lacks critical security headers such as Content-Security-Policy and HSTS that protect against common web attacks. The absence of a vulnerability disclosure policy and security.txt file indicates limited incident response readiness. Contact forms lack CAPTCHA enforcement, increasing risk of spam and potential abuse. There is no visible evidence of compliance with advanced data protection frameworks beyond GDPR basics. The site does not expose sensitive data but could improve by implementing recommended security best practices and regular vulnerability assessments. Overall, the security culture appears basic and would benefit from strategic enhancements.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-XSS-Protection, and Strict-Transport-Security.
  2. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  3. Enable CAPTCHA or other anti-spam mechanisms on all contact forms to reduce abuse.
  4. Introduce a cookie consent banner and cookie policy to improve privacy compliance and user transparency.
  5. Enhance digital marketing by integrating social media links and analytics tools for better customer engagement and business insights.

Technical notes

Notes

The website is built on a WordPress CMS platform using a modern theme (The7) and popular plugins such as WPBakery Page Builder and Yoast SEO, indicating a well-supported technical infrastructure. The site loads scripts asynchronously and uses lazy loading for images, which helps performance. However, no advanced caching or CDN usage was detected from the provided data. The site is mobile responsive with good navigation clarity. Accessibility features are basic and could be improved. The lack of security headers and cookie consent mechanisms indicates some technical debt in security and privacy compliance. Overall, the infrastructure is stable but could benefit from modernization efforts focused on security and privacy enhancements.
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.
