AI Summary
Technický a zkušební ústav stavební Praha, s.p. (TZÚS Praha) is the largest testing and certification organization in the Czech Republic specializing in conformity assessment of construction products. The organization provides a broad range of services including product certification, management system certification, testing, building certification, inspection, metrology, and technical consultancy. The website targets construction industry professionals, manufacturers, importers, and investors, positioning itself as a leading national authority in its sector. The website infrastructure utilizes Bootstrap 3.3.7, jQuery 1.11.3, and Google reCAPTCHA v2 for form security. The site is mobile optimized with a clear navigation structure and cookie consent mechanisms that comply with GDPR requirements. However, some technologies are dated, and security headers are not evident, suggesting room for technical modernization and enhanced security hardening. Security posture is strong with HTTPS enforced, CSRF protection, and reCAPTCHA integration, but lacks published security policies and incident response contacts. The absence of WHOIS data reduces domain trustworthiness, though the professional presentation and content quality support legitimacy. No vulnerabilities or exposed sensitive data were detected. Overall, the website is professional, secure, and compliant with privacy regulations, but improvements in transparency (privacy policy, security policy) and technical updates are recommended to enhance trust and security maturity.

Security Posture Analysis
Comprehensive Security Assessment
The website demonstrates a mature security posture with HTTPS enforced, CSRF tokens on forms, and Google reCAPTCHA protecting user inputs. Cookie consent is granular and GDPR compliant, reflecting good privacy practices. However, the absence of explicit security policies, incident response contacts, and security headers such as Content-Security-Policy or X-Frame-Options indicates areas for improvement. The use of older JavaScript libraries like jQuery 1.11.3 may expose the site to known vulnerabilities if not regularly patched. No signs of exposed sensitive data or vulnerabilities were found. Overall, the security posture is good but could be enhanced by publishing security documentation and updating technical components.
Strategic Recommendations
Priority Actions for Security Improvement
