n the modern digital workspace, ensuring data security is paramount. Notion AI, a notable player in this domain, employs robust data encryption standards to protect user data both at rest and in transit. This article delves into the specifics of these encryption practices, shedding light on how Notion AI safeguards the data entrusted to it.

Encryption at Rest

Notion AI employs Advanced Encryption Standard (AES) with a 256-bit key length to encrypt data at rest. This encryption standard is recognized globally and is used by a myriad of organizations to secure sensitive data. When data is at rest, whether it's on Notion’s internal networks, in cloud storage, database tables, or backups, it's encrypted using AES-256​.


Encryption in Transit

When data is being transmitted over networks, it's crucial to have robust encryption to prevent unauthorized access. Notion AI uses Transport Layer Security (TLS) 1.2 or greater for encrypting data in transit. TLS is a standard protocol for securing network communication, not a specific encryption algorithm, but it provides the framework that enables Notion to maintain a secure communication channel for data transit.


Additional Security Measures

Besides encryption, Notion AI incorporates other security measures to bolster data protection. These include SSL/TLS encryption, two-factor authentication (2FA), firewall and Security Information and Event Management (SIEM) Access Control. Notion does not currently offer end-to-end encryption, which implies that while data is encrypted on the server and during transit, there's no end-to-end encryption from the client to the server​​.


AES-256 and TLS: Why are they Significant?

AES-256 and TLS are significant due to their robustness and widespread adoption. AES-256 is a symmetric encryption algorithm known for its high level of security and speed, making it a popular choice for encrypting data at rest. On the other hand, TLS is essential for safeguarding data in transit, ensuring that any data sent between the Notion AI server and clients remains confidential and intact​​.


Final Thoughts

Notion AI has put in place stringent encryption standards to secure user data. By employing AES-256 for data at rest and TLS 1.2 or greater for data in transit, Notion AI ensures that user data remains secure, whether stored or being transmitted. The lack of end-to-end encryption is a noted shortfall, but the existing encryption standards and additional security measures provide a substantial level of data protection.
