HET spol. s r.o. is a Czech manufacturing company specializing in the production of interior and facade paints, thin-layer plasters, penetration coatings, and protective oils for wood, metal, and concrete surfaces. The company targets both DIY enthusiasts and professional customers, offering a broad product range with a focus on quality and price balance. Their market position is that of an established local manufacturer with certifications such as ISO 9001, indicating quality management standards. Technically, the website employs modern front-end technologies including Google Tag Manager, Cookiebot for cookie consent, and jQuery, with good mobile optimization and accessibility features. Security posture is moderate; HTTPS is used, but no explicit security headers were detected in the HTML source, and no incident response or security policies are published.

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 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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  2. 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

The company operates in the manufacturing sector, focusing on paints and coatings for various surfaces. Their business model includes direct sales and partnerships, supported by a B2B portal and color simulation tools. The presence of related domains such as prohet.cz and klasikcolor.cz indicates a partnership ecosystem enhancing product offerings and customer engagement. The company leverages social media channels for marketing and brand presence. Growth indicators include recent news updates and EU grant projects. The company targets both retail consumers and industrial clients, positioning itself as a quality-focused manufacturer with competitive pricing.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is implemented, and cookie consent is managed via Cookiebot, indicating awareness of privacy regulations. However, the lack of visible security headers such as Content Security Policy, HSTS, and X-Frame-Options is a gap. No explicit security or incident response policies are published, and no dedicated security contact information is provided. The absence of WHOIS data is a concern for domain legitimacy and transparency. There are no visible vulnerabilities or exposed sensitive data in the HTML content. Overall, the security posture is adequate for a commercial website but could be improved to meet higher compliance and trust standards.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service pages accessible from the homepage.
  2. Add security headers (CSP, HSTS, X-Frame-Options, X-XSS-Protection) to enhance protection against common web attacks.
  3. Publish explicit security and incident response policies, including contact channels for security issues.
  4. Improve WHOIS registration transparency to enhance domain trustworthiness.
  5. Regularly audit third-party scripts and tracking tools to ensure compliance with privacy regulations and minimize user tracking.

  3. Cookie consent is implemented via Cookiebot.
  4. No explicit privacy policy or terms of service pages detected on homepage HTML.
  5. Social media presence on Facebook and Instagram is active.
  6. ISO 9001 certification is prominently linked.
  7. No contact emails or phone numbers explicitly found in the provided HTML content.

Technical notes

Notes

The website uses a modern front-end stack with jQuery 3.5.1, Google Tag Manager for analytics, Cookiebot for cookie consent management, and Google Fonts for typography. The carousel uses keen-slider for interactive UI elements. The site is mobile optimized with responsive design and accessibility features such as skip links and ARIA attributes. Performance is moderate, with preloading of key scripts and optimized images. No CMS or hosting provider information is detected from the HTML source. The site lacks visible security headers, which is a technical risk. Overall, the technical implementation is solid but could benefit from enhanced security configurations and improved WHOIS data management.
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.
