How does Notion encrypt data?

Notion protects your data through industry-standard AES-256 encryption for information stored on servers and TLS 1.2 or higher encryption for data traveling between your device and Notion's servers. This dual-layer approach ensures your workspace content remains secure whether it's sitting in storage or being actively accessed across different devices. The company manages these encryption keys through automated Key Management Services (KMS), which handles the complex processes of generating, storing, and rotating the digital keys that unlock your encrypted data.

AES-256 encryption converts your stored data into an unintelligible format using 256-bit keys, making unauthorized access computationally infeasible even with advanced computing power. This same encryption standard protects your automated daily backups, ensuring historical versions of your work remain just as secure as current content. When you're actively using Notion, TLS encryption creates a secure tunnel for data transmission, preventing interception during the journey between your browser and Notion's servers.

The encryption system operates seamlessly within Notion's broader security infrastructure hosted on Amazon Web Services, which provides additional layers of protection including network firewalls and intrusion detection systems. Your account can be further secured through multi-factor authentication, adding an extra verification step beyond your password. For Enterprise Search and AI features, Notion maintains SOC 2 Type 2 certification and follows strict permission synchronization, ensuring you only access data you're authorized to see.

While this encryption approach provides robust protection for most users, it's worth noting that Notion isn't explicitly HIPAA certified, which might matter for healthcare organizations with strict compliance requirements. Additionally, like most cloud-based tools, your data security also depends on your own practices—using strong passwords, enabling two-factor authentication, and carefully managing workspace permissions all contribute to your overall security posture.

Understanding how Notion encrypts your data can help you make informed decisions about what information you're comfortable storing in your workspace. The combination of strong encryption standards, automated key management, and comprehensive security monitoring creates a reliable foundation for protecting your productivity data, whether you're managing personal projects or collaborating with large teams on sensitive business information.
