Security Posture Analysis
Comprehensive Security Assessment
Zhihu exhibits a solid security foundation with enforced HTTPS, secure authentication options including SMS and password login, and integration of Sentry for real-time error and exception monitoring. The platform provides clear channels for abuse reporting and content violation notifications, reflecting incident response readiness. However, the lack of explicit security headers such as Content-Security-Policy and cookie consent mechanisms indicates areas for improvement in defense-in-depth and privacy compliance. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Compliance with Chinese regulatory requirements is evidenced by multiple official certifications. Overall, Zhihu maintains a mature security posture appropriate for a large-scale internet platform but should enhance transparency and user privacy controls.
