53/100

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

VKF Renzel ČR s.r.o. operates a professional B2B e-commerce platform specializing in retail sales support products such as display stands, promotional items, and retail equipment. The website reflects a medium-sized company with consistent branding and a clear market focus on retail and promotional sectors within the Czech Republic. The technical infrastructure leverages modern web technologies including JavaScript frameworks, cookie consent management, and analytics tools, indicating a mature digital presence. Security posture is generally strong with HTTPS enforced and cookie consent implemented, though the absence of security headers and explicit privacy policies suggests room for improvement. The lack of WHOIS data reduces domain trust but does not detract from the professional presentation and business legitimacy evident on the site.

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

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics

      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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

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

  • Security headers: did not complete in this scan.
  • 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 is positioned as a regional leader in retail sales support solutions, offering a broad product catalog with customizable options. Its business model centers on direct online sales and catalog-based ordering, targeting retail businesses and marketing professionals. The presence of multiple sister domains under the VKF Renzel brand indicates a well-established group structure. The website's product reviews and structured data enhance credibility, while the use of analytics and marketing tools supports growth and customer engagement strategies.

Security posture

The website demonstrates a solid security foundation with HTTPS and cookie consent mechanisms. However, the absence of key security headers such as Content-Security-Policy and lack of published security or incident response policies highlight potential compliance gaps. No vulnerabilities or exposed sensitive data were detected in the content. The missing WHOIS data is a concern for domain legitimacy but does not directly impact site security. Overall, the security maturity is moderate with recommendations to enhance header policies and transparency.

Recommendations

  1. Implement and publish a comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Add essential security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to strengthen protection against common web attacks.
  3. Publish clear incident response and security contact information to facilitate vulnerability reporting and incident management.
  4. Consider deploying a security.txt file to formalize vulnerability disclosure processes.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Key observations

  1. Website is fully accessible with rich product content and e-commerce features.
  2. No WHOIS data available, which is unusual and reduces domain trust.
  3. Cookie consent and privacy mechanisms are implemented but privacy policy page not clearly found.
  4. No explicit security or incident response policies published.
  5. Business information is well presented via structured data and product catalog.
  6. No suspicious or malicious indicators detected in content or linked domains.
Technical notes

Notes

The website uses a modern tech stack including JavaScript frameworks (likely Vue.js), Bootstrap for responsive design, and third-party services like Usercentrics for consent management and Econda for analytics. The CMS appears to be a proprietary or custom RA-Theme system. Performance is moderate with good mobile optimization and SEO practices. The site is well-structured with rich metadata and structured data enhancing search engine visibility. Opportunities exist to improve accessibility and security header implementation to reduce technical debt and improve resilience.
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.
