Datlab s.r.o. operates the website Tendry.cz, a specialized platform providing daily public procurement opportunities for businesses in the Czech Republic. The company leverages data acquisition and analysis expertise to aggregate over 25,000 sources of public contract data, offering AI-driven smart monitoring and email alerts to its users. Positioned as a niche leader in the Czech public procurement sector, Tendry.cz targets companies across multiple industries including construction, transportation, and office supplies. Technically, the website employs modern frontend technologies such as Vue.js and Bootstrap, hosted by Wedos, a reputable Czech hosting provider. The site is mobile-optimized and features a professional design with clear navigation. However, some technical improvements are recommended, including enhanced accessibility and SEO optimizations. From a security perspective, the site uses HTTPS and defers script loading for performance but lacks explicit security headers and published security policies. No critical vulnerabilities or suspicious content were detected. Privacy compliance is limited due to the absence of privacy and cookie policies, which should be addressed to meet GDPR requirements. Overall, Tendry.cz presents a trustworthy and professional online presence with a solid business model and technical foundation. Strategic improvements in privacy compliance and security posture will enhance user trust and regulatory adherence.

Security Posture Analysis
Comprehensive Security Assessment
The current security maturity level of Tendry.cz is moderate. The website enforces HTTPS, which is mandatory for secure communications. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No explicit incident response or vulnerability disclosure policies are published, which limits transparency and preparedness. Data protection practices are not fully documented, and GDPR compliance indicators are weak due to missing privacy and cookie policies. The site does not expose sensitive data or show signs of vulnerable libraries. Overall, while no critical security flaws are evident, enhancements in security headers, policy transparency, and compliance documentation are recommended to strengthen the security posture and build user trust.
Strategic Recommendations
Priority Actions for Security Improvement
Implement and publicly disclose a comprehensive privacy policy and cookie policy to ensure GDPR compliance.
