Mediatom, the ad mediation platform, has recently been granted the National Class 3 Cybersecurity Protection Filing Certification.
Earning this certification signifies that Mediatom has received authoritative recognition for its information security management, platform protection capabilities, and compliance operations framework – further demonstrating the platform's long-term commitment to data security and developer service experience.

一. Why Is Class 3 Cybersecurity Protection Certification So Important?
The National Cybersecurity Protection Level System is a foundational mandatory standard in China's information security domain. The higher the level, the more stringent the security requirements.
Among all levels, Class 3 represents the highest level of security certification for non-banking institutions in China. It requires platforms to meet rigorous standards across nearly 300 control points spanning physical security, network security, host security, application security, data security, and backup and recovery – all validated through on-site assessments and ongoing supervision by accredited evaluation agencies.
To pass this certification, Mediatom had to demonstrate the following core capabilities:
Data Security: Encrypted transmission and storage of user data, with strict access control over data permissions
Business Continuity: High-availability deployment at critical nodes, enabling rapid recovery even in the event of anomalies
Attack Defense: Multi-layered protection systems against intrusion, tampering, and data leakage
Continuous Compliance: Subject to regular supervisory inspections by regulatory authorities, ensuring security capabilities remain always operational
二. What Does Mediatom's Class 3 Certification Mean for Developers?
