Business Intelligence
Market & Strategic Analysis
The platform positions itself as a comprehensive online calculator hub, likely monetized through advertising and membership services. It serves the education and general utility sector in China, providing tools for students, professionals, and general users. The extensive network of related subdomains and partner sites indicates a broad ecosystem. However, the lack of clear business registration and contact information limits transparency. The site’s content quality and navigation are strong, supporting user retention and engagement. Strategic partnerships with CMS providers and AI tool integrations suggest ongoing development and expansion.
Security Posture Analysis
Comprehensive Security Assessment
Security maturity is moderate. The presence of CSRF tokens indicates awareness of input security, but the absence of HTTP security headers (CSP, HSTS, X-Frame-Options) is a notable gap. No explicit privacy or cookie policies were found, which may impact GDPR compliance. The use of third-party scripts like Google Adsense and Baidu Analytics introduces tracking and potential privacy concerns. WHOIS data is missing, which could be a risk factor for domain legitimacy. Incident response and vulnerability disclosure mechanisms are not evident, suggesting limited readiness for security incidents.
Strategic Recommendations
Priority Actions for Security Improvement
Implement comprehensive privacy and cookie policies with user consent mechanisms to improve compliance.
