Encryption in transit and at rest
Files in Zoho Docs are encrypted at rest with 256-bit Advanced Encryption Standard (AES). During transit, Perfect Forward Secrecy (PFS) generates a unique key for each session to encrypt files. Zoho Docs's servers and clients are connected through SSL and secured with an RSA-based 2048-bit encryption key.
With multiple file backup locations, your information is always safe. Multiple copies of your files are stored in different locations, thereby protecting your data from any disaster or hardware failure.
Virus, malware, and spam detection
Any files within Zoho Docs go through virus, malware, and spam checks to detect any infections. Such files are prevented from being distributed to others.
