Risk levelMedium

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

Prokennex.cz is a Czech Republic-based retailer specializing in sports equipment for tennis, badminton, and squash, with a unique focus on their proprietary Kinetic technology designed to reduce injury risk. The website presents a professional and consistent brand image, targeting athletes of all levels. Their business model includes direct retail, a B2B platform, and a customer loyalty program called Kinetic klub. Technically, the site runs on Drupal 7 with Bootstrap and integrates common marketing and analytics tools such as Google Analytics and Facebook Pixel. While the site is mobile-optimized and well-structured, it lacks visible privacy and cookie policies, which is a compliance concern. Security-wise, HTTPS is enforced, but the absence of explicit security headers and vulnerability disclosure mechanisms indicates room for improvement. The WHOIS data is unavailable, which reduces domain trustworthiness, but the website content and structure suggest a legitimate business presence.

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

    • 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

      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. 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 Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

Prokennex operates in a niche retail segment focused on sports rackets with advanced shock-absorbing technology. Their competitive advantage lies in the patented Kinetic system and a network of retailers supported by a B2B platform. The company targets amateur and professional athletes, leveraging testimonials from recognized players to build trust. Revenue streams likely include direct sales, B2B partnerships, and membership benefits through the Kinetic klub. The website's integration of multiple tracking and retargeting services indicates an active marketing strategy. However, the lack of transparent privacy and security policies may impact customer trust and regulatory compliance.

Security posture

The website demonstrates a moderate security posture with HTTPS enabled and secure form tokens via Drupal. However, the absence of key security headers such as Content Security Policy, HSTS, and X-Frame-Options weakens defenses against common web attacks. No evidence of exposed sensitive data or vulnerable libraries was found, but the use of an older CMS version (Drupal 7) may pose risks if not regularly patched. There is no visible incident response or vulnerability disclosure information, which limits transparency and preparedness. Privacy compliance is weak due to missing policies and consent mechanisms, potentially exposing the company to regulatory risks under GDPR.

Recommendations

  1. Implement and prominently display comprehensive privacy and cookie policies with user consent mechanisms to ensure GDPR compliance.
  2. Add essential security headers (CSP, HSTS, X-Frame-Options, X-XSS-Protection) to enhance protection against web vulnerabilities.
  3. Upgrade or patch the Drupal 7 CMS to the latest secure version or consider migrating to a supported platform to reduce security risks.
  4. Publish a security.txt file and establish a clear vulnerability disclosure process to improve transparency and incident response readiness.
  5. Provide clear contact information including emails and phone numbers for customer support and security incident reporting to build trust.

Technical notes

Notes

The website is built on Drupal 7 CMS with Bootstrap for responsive design and jQuery 1.7 for JavaScript functionality. It uses Google Fonts for typography and integrates Google Tag Manager, Facebook Pixel, and Seznam Retargeting for marketing and analytics. The site is mobile-optimized and has a clear navigation structure. Performance is moderate, with multiple CSS and JS files loaded. The lack of modern JavaScript frameworks and older jQuery version may indicate technical debt. No hosting provider information was detected. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic, with some ARIA landmarks and skip links present.
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.
