AI Summary

The website www.schranka-duvery.cz is operated by COOLINTSOFT s.r.o. and provides an online trust box service targeted at primary and secondary schools in the Czech Republic. The platform enables anonymous, secure communication between students, parents, and designated school staff, primarily prevention methodologists. The business model is subscription-based with a free trial month and yearly prepaid plans. The website content is well-structured, professionally designed, and focused on its niche educational audience. Technically, the site uses a modern front-end stack including jQuery, Font Awesome, Google Fonts, and animation libraries. It is mobile-optimized and includes CAPTCHA protection on its contact form. However, no CMS or hosting provider information is evident, and some SEO and accessibility features are basic. The site uses HTTPS with a valid SSL certificate but lacks security headers and cookie consent mechanisms. From a security perspective, the site demonstrates good practices such as HTTPS enforcement and CAPTCHA use but misses important headers and explicit security or incident response policies. The absence of WHOIS data for the domain reduces trust and raises questions about domain registration legitimacy. No tracking or advertising scripts are present, indicating a privacy-conscious approach. Overall, the website is functional, professional, and safe for its intended audience but would benefit from improved security headers, cookie consent compliance, and transparency regarding domain registration to enhance trust and compliance.

Security Posture Analysis

Comprehensive Security Assessment

The website's security posture is moderate to good. HTTPS is properly implemented with a valid SSL certificate, and CAPTCHA protects the contact form from spam. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a notable gap. No incident response or security policy information is published, and no vulnerability disclosure mechanism is present. The lack of WHOIS data for the domain is a significant concern, potentially indicating registration or privacy issues. No exposed sensitive data or vulnerable libraries were detected. Overall, the site is secure for general use but could improve compliance and resilience by adopting recommended security headers and transparency measures.
