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

VKF Renzel (U.K.) Ltd. is a well-established UK-based supplier and manufacturer specializing in point-of-sale (POS) display products, including acrylic and PVC items. With a market presence of over 30 years, the company serves retail, hospitality, healthcare, and education sectors, offering both standard and bespoke display solutions. Their online platform provides a comprehensive catalog of over 25,000 products, supported by custom manufacturing and large format printing services. The company emphasizes sustainability and customer support, positioning itself as a leading POS supplier in the UK market. Technically, the website is built on a modern stack including Bootstrap and OXID eShop CMS, with integrations for consent management (Usercentrics) and analytics (Econda). The site is mobile-optimized, well-structured, and employs secure HTTPS connections. Privacy and cookie policies are clearly presented with active consent mechanisms, reflecting good GDPR compliance. Contact information is comprehensive and prominently displayed, enhancing business credibility. Security posture is strong with HTTPS enforced and no visible vulnerabilities or exposed sensitive data. However, the absence of some advanced security headers suggests room for improvement. The WHOIS lookup failed due to a domain naming rules violation error from Nominet, which is unusual and reduces trust in domain registration transparency. Despite this, the website content and business information appear legitimate and professional. Overall, VKF Renzel's digital presence is robust and professional, supporting its market position. The main risk lies in the domain registration anomaly, which should be investigated further to ensure full legitimacy and trustworthiness.

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

3 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.

    • 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

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

VKF Renzel operates as a B2B supplier and manufacturer in the retail display and POS industry, targeting businesses requiring promotional and display solutions. Their competitive advantage includes a large product range, bespoke manufacturing capabilities, and a strong UK market presence. The business model combines e-commerce with custom services, supported by a knowledgeable sales and design team. The company leverages digital marketing, social media, and analytics to drive engagement and sales. Growth indicators include continuous product expansion and sustainability initiatives. Partnerships with payment processors and consent management providers enhance operational efficiency. Strategic observations highlight the importance of resolving WHOIS inconsistencies to maintain trust and support future growth.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and secure payment methods prominently displayed. Privacy compliance is well-managed through Usercentrics CMP and clear policies. No critical vulnerabilities or exposed sensitive data were detected. However, the lack of some recommended security headers (e.g., Content-Security-Policy) and absence of explicit incident response or security policy pages indicate areas for enhancement. The WHOIS data anomaly is a concern for domain legitimacy but does not directly impact website security. Overall, the security culture appears proactive but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Implement additional HTTP security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Investigate and resolve the WHOIS domain registration anomaly with Nominet to improve domain legitimacy and trust.
  3. Enhance accessibility features to comply with standards and improve user experience for all visitors.
  4. Establish and publish formal security policies and incident response procedures to demonstrate security governance.
  5. Regularly audit third-party scripts and analytics integrations to ensure no vulnerabilities or privacy issues arise.

Technical notes

Notes

The website is built on a modern and stable technical infrastructure using OXID eShop CMS and Bootstrap framework, ensuring responsive design and good user experience across devices. JavaScript libraries and consent management tools are properly integrated. Performance is moderate with some lazy loading and preloading optimizations. SEO is well addressed with meta tags, Open Graph, and structured data (JSON-LD) for organization and website schema. Technical risks are minimal but include potential improvements in security headers and accessibility compliance. Hosting provider details are not explicitly identified from the content.
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.
