The website reflects a mature digital presence with modern technologies such as Vue.js and integrated analytics and consent management tools. Security posture is strong with HTTPS, security headers, and cookie consent mechanisms, although explicit privacy and security policy pages are not found in the provided content.

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

5 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, YouTube

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

  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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  3. 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 primarily in the manufacturing and retail sectors, focusing on hazardous materials storage and safety. Its business model combines B2B e-commerce with consulting and training services, including the DENIOS Academy. The website showcases a strong market position with trust signals such as free shipping, expert advice, and a 30-day return policy. The target audience includes industrial clients in the Czech Republic. The company leverages modern web technologies and analytics to optimize user experience and marketing efforts. No direct parent or subsidiary relationships are evident from the data. The absence of WHOIS details is typical for CZ domains but warrants monitoring for legitimacy. The company’s digital ecosystem includes integrations with trusted third-party services for analytics and consent management, supporting growth and compliance.

Security posture

The website demonstrates a good security posture with enforced HTTPS, multiple security headers, and a robust cookie consent mechanism via OneTrust. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the absence of a public security policy or incident response contact limits transparency. No vulnerability disclosure or security.txt file is present, which could be improved to enhance trust and facilitate responsible vulnerability reporting. The site uses reputable analytics and marketing tools with user consent controls, aligning with GDPR requirements. Overall, the security maturity is solid for a commercial website but could benefit from enhanced policy disclosures and incident response readiness.

Recommendations

  1. Publish a clear and accessible privacy policy page linked from the homepage.
  2. Add a dedicated security policy and incident response contact information.
  3. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance website accessibility features to improve compliance and user experience.
  5. Regularly review and audit third-party scripts and analytics tools for security and privacy compliance.

Notes

The website is built using Vue.js, leveraging modern JavaScript frameworks for dynamic content delivery. It integrates Google Tag Manager, Econda Analytics, Hotjar, and OneTrust for analytics and consent management, indicating a mature digital marketing infrastructure. The site uses Swiper.js for interactive sliders and ETRUSTED widgets for customer reviews. Performance is moderate with good mobile optimization and SEO practices. The CMS appears custom or proprietary, with no common CMS signatures detected. Hosting provider details are not evident from the content. The site employs standard security headers and HTTPS, contributing to a secure browsing environment. Opportunities exist to improve accessibility and to publish more comprehensive privacy and security documentation.
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.
