CTERA

CTERA is a simple and secure file storage and sharing system that works like a super-smart company file server in the cloud. It lets teams save, sync, and access their important documents from any computer or phone while keeping everything organized and protected. It uses affordable S3-compatible object storage behind the scenes to hold all the actual files, which keeps costs low and makes everything scale easily as the company grows. This S3 storage acts like a giant, reliable digital warehouse that CTERA taps into so users never have to worry about running out of space or losing files. The combination gives businesses enterprise-level file services without the high price tag or complexity of traditional storage systems.
