AI Summary
Tenisová škola Zýka Hořovice is a small, family-run tennis school based in the Czech Republic with over 20 years of experience. The business focuses on tennis training for children and competitive players, offering services such as racket stringing and court rentals. The website is built on the eStránky.cz platform and integrates basic technologies like jQuery and Facebook SDK for social media connectivity. However, the site lacks critical compliance documents such as privacy and cookie policies and does not provide contact emails, limiting its professional and compliance posture. The absence of WHOIS data raises concerns about domain legitimacy, although the site content appears genuine and targeted at local tennis enthusiasts.

Business Intelligence
Market & Strategic Analysis
The tennis school operates in the local sports education sector, targeting children and amateur tennis players in Hořovice and surrounding areas. Its business model revolves around training services, court rentals, and ancillary offerings like racket stringing. The website's market position is that of a small, community-focused entity with a long-standing presence. The lack of detailed business registration or certification information limits visibility into its formal business structure. The site uses basic marketing tools and social media integration but lacks advanced analytics or tracking. Growth potential may be constrained by limited digital maturity and absence of comprehensive online engagement features.
Security Posture Analysis
Comprehensive Security Assessment
The website exhibits a low security maturity level. There is no evidence of HTTPS enforcement or security headers, and the JavaScript libraries used are outdated, potentially exposing the site to known vulnerabilities. No privacy or cookie policies are published, indicating non-compliance with GDPR and related regulations. The absence of incident response contacts or security policies further weakens the security posture. While no explicit vulnerabilities or malware were detected, the lack of basic security best practices and domain registration transparency poses risks to trust and data protection.
Strategic Recommendations
Priority Actions for Security Improvement
Implement HTTPS with a valid SSL certificate and enforce secure connections site-wide.
