Diony Sports operates an e-commerce platform specializing in high-quality Czech gymnastics equipment, targeting gymnastics clubs, athletes, and sports facilities. The company positions itself as a competitive alternative to leading international brands by offering quality products at lower prices. The website features a comprehensive product catalog, 3D project services, and certifications such as FIG, enhancing its market credibility.
Technically, the website employs modern JavaScript libraries, Google Analytics, and embedded YouTube videos to engage users and track performance. The site is accessible, uses HTTPS, and includes a cookie consent mechanism, though mobile optimization and accessibility are basic. No CMS or hosting provider details were identified.
From a security perspective, the site benefits from HTTPS but lacks visible security headers and formal privacy or terms of service pages. No contact information for incident response or data protection officers is provided. The absence of WHOIS registration data raises concerns about domain legitimacy, although the website content and branding appear professional and trustworthy.
Overall, the site is functional and business-focused but would benefit from enhanced security practices, clearer privacy compliance, and verified domain registration to improve trust and compliance posture.

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.

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.

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.

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.

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.

Business context
Business profile
Diony Sports targets a niche market in gymnastics equipment manufacturing and retail, leveraging Czech manufacturing quality and competitive pricing. Their business model centers on direct e-commerce sales with additional services like 3D project design for gymnastics halls. The company maintains a moderate market position supported by FIG certification and partnerships. Growth indicators include product innovation (e.g., stretch mats) and participation in sports events. The partnership with Algorim for website development suggests a professional digital presence. However, lack of visible contact details and privacy policies may limit customer trust and regulatory compliance.
Security posture
The website demonstrates a basic security posture with HTTPS enabled and a cookie consent banner, indicating awareness of privacy regulations. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response information is available, which may hinder timely security issue management. The missing WHOIS data is a significant red flag for domain legitimacy and trust. Overall, the security maturity is moderate but requires improvements to meet best practices and compliance standards.
Recommendations
Implement and publish a comprehensive privacy policy and terms of service to enhance legal compliance and user trust.
Add security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to improve protection against web vulnerabilities.
Verify domain registration and ensure WHOIS data is available and accurate to improve legitimacy and trustworthiness.
Provide clear contact information including security incident response contacts and data protection officer details.
Enhance mobile responsiveness and accessibility features to improve user experience and compliance with accessibility standards.

Technical notes
Notes
The website uses a modern JavaScript-based front end with jQuery and asynchronous loading of Google Analytics and YouTube embeds. The HTML structure is valid and includes meta tags for SEO and Open Graph for social sharing. The site lacks a detected CMS, suggesting a custom or proprietary platform. Performance is moderate with no evident broken elements. Mobile optimization is basic, and accessibility features are minimal. The hosting provider and infrastructure details are not disclosed. There is an opportunity to modernize the tech stack further and improve performance and accessibility.
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.
