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

Tomáš Kuchař - TKSOLAR is a small Czech Republic-based company specializing in comprehensive home energy services including photovoltaic system installations, water heating, heat pumps, wallbox installations, and complete electrical installations. The website presents a professional and clear business description targeting residential customers seeking energy solutions. The technical infrastructure is based on WordPress with the Divi theme and SEO plugins, indicating moderate digital maturity. The website is accessible without WAF or security challenges, but lacks important compliance documents such as privacy and cookie policies. Security posture is moderate with no detected security headers and unknown SSL configuration. The absence of WHOIS data reduces domain legitimacy confidence. Overall, the website is functional and professional but requires improvements in security and compliance to enhance trust and reduce risk.

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

10 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  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

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 residential photovoltaic and heating solutions. Its business model is service-oriented, providing installation and electrical services. Market positioning appears local and small-scale with no evidence of subsidiaries or parent companies. The website content is consistent and well-branded, supporting a moderate level of business credibility. Lack of detailed contact information and absence of privacy policies suggest areas for growth in customer trust and regulatory compliance. No partnerships or related domains were identified from the website content.

Security posture

The current security maturity level is basic to moderate. The website uses HTTPS (implied by canonical URLs) but lacks visible security headers such as Content-Security-Policy or X-Frame-Options. No vulnerability disclosures or incident response contacts are present. The absence of privacy and cookie policies indicates compliance gaps with GDPR and related regulations. No analytics or tracking scripts were detected, which limits exposure but also reduces insights into user behavior. The WHOIS data absence is a concern for domain legitimacy and trust. Recommendations include implementing security headers, publishing compliance documents, and establishing vulnerability disclosure mechanisms.

Recommendations

  1. Implement comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Verify and publish WHOIS domain registration details to enhance domain legitimacy.
  4. Establish a vulnerability disclosure policy or security.txt file to improve security transparency.
  5. Enhance contact information with verified company emails and physical addresses to boost business credibility.

Technical notes

Notes

The website is built on WordPress using the Divi theme and All in One SEO plugin, indicating a common and flexible CMS platform. The use of Google Fonts and structured data (JSON-LD) for organization and breadcrumb markup supports SEO best practices. Performance is moderate with no explicit indicators of slow loading but no advanced optimization detected. Mobile responsiveness is good due to Divi's responsive design. Accessibility features are basic, with room for improvement. No advanced analytics or tracking technologies were found, suggesting minimal user tracking. The technical stack is standard for small business websites but could benefit from enhanced security and compliance features.
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.
