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

VENTA spol. s r.o. is a Czech Republic based company established in 1991 specializing in sales, installation, and turnkey solutions for home energy systems including heating, plumbing, solar, and ventilation. The company operates both physical retail locations and multiple e-commerce platforms, positioning itself as a trusted provider with a broad product portfolio and certified installation services. The website reflects a mature business with consistent branding and a focus on customer service including 3D design and subsidy assistance. Technically, the site uses modern frontend technologies such as Bootstrap and jQuery, with Google reCAPTCHA v3 integrated for form security. While the site is mobile optimized and well-structured, it lacks some advanced security headers and explicit incident response policies. The domain registration data aligns well with the business claims, indicating legitimacy and long-term operation. Overall, the website is professional, secure, and compliant with basic privacy regulations, though there is room for improvement in security policies and transparency.

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

9 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

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 holds a solid market position in the energy and home installation sector in the Czech Republic, leveraging a multi-channel business model combining retail, e-commerce, and turnkey services. Its competitive advantages include a wide supplier network, certified installation teams, and value-added services such as 3D bathroom design and subsidy management. The partnership with Sanplast and operation of multiple e-shops indicate a diversified revenue stream and strong supplier relationships. The target customers include homeowners, businesses, and hospitality providers. The company’s long history and physical presence enhance trust and market credibility. Strategic observations suggest focusing on expanding digital marketing and enhancing security transparency to further strengthen market position.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and Google reCAPTCHA v3 protecting user input forms. However, the absence of key security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of publicly available security or incident response policies indicates a gap in transparency and preparedness. Compliance with GDPR is indicated by the presence of privacy and cookie policies, but no dedicated data protection officer contact or vulnerability disclosure mechanisms were found. Overall, the security posture is adequate for the business size but could be improved by implementing recommended headers and publishing security policies.

Recommendations

  1. Implement comprehensive HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response plan on the website to improve transparency and customer trust.
  3. Regularly update all JavaScript libraries and dependencies to mitigate risks from known vulnerabilities.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Enhance privacy compliance by providing explicit contact details for a Data Protection Officer or privacy contact.

Technical notes

Notes

The website uses a stable and widely supported technology stack including jQuery, Bootstrap, and Google reCAPTCHA v3, ensuring compatibility and basic security. Hosting appears to be managed by a Czech hosting provider (svethostingu.eu) with domain registration dating back to 2004, supporting business continuity. Performance is moderate with some room for optimization, particularly in SEO and accessibility features. The site is mobile responsive and offers a good user experience with clear navigation and professional design. Technical debt is low but could be reduced further by modernizing some libraries and enhancing SEO metadata. Overall, the technical infrastructure supports the business needs effectively with opportunities for modernization and security hardening.
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.
