How Encryption Actually Protects Your Documents

Encryption in transit protects data while it's moving, between your browser and a server, for example, so that someone intercepting network traffic can't read it. Encryption at rest protects data while it's stored, so that someone gaining unauthorized access to a server's storage still can't read the files directly.

Both matter, and they protect against different scenarios. A platform that only implements one of the two has a meaningful gap, even if it advertises 'encryption' broadly.

Not all encryption is equally strong. Industry-standard approaches, like AES-256 for data at rest and TLS for data in transit, reflect protocols that have been extensively reviewed and tested over time. A platform using outdated or custom, unreviewed encryption methods is taking on risk that isn't obvious from the outside.

This is one of the more reasonable questions to ask a vendor directly: what specific standards are used, and are they current, well-vetted ones.

Encryption protects data from being read by someone who intercepts or accesses it improperly. It doesn't protect against someone with legitimate access misusing that access, which is where access controls and permissions, a separate layer of security, become just as important.
