AWS Wickr is an end-to-end encrypted enterprise communication service that allows secure collaboration across messaging, voice and video calling, file sharing, and screen sharing. The service is now in preview. AWS Wickr helps organizations address evolving threats and regulations by combining security and administrative features designed to safeguard sensitive communications, enforce information governance policies, and retain information as required. Encryption takes place locally, on the endpoint. Every call, message, and file is encrypted with a new random key, and no one but intended recipients—not even AWS—can decrypt them.
