Best in class security
& privacy

Kairos uses best in class security practices and protocols. Faces in photos are immediately masked as templates so that identities cannot be discovered. We use strong encryption methods, like AES-256, to encrypt data stored in cloud storage, ensuring data remains secure while at rest and we use TLS to protect data as it's transferred between the client and server or across data centers.
