CTERA

CTERA Networks is an Israeli company that develops enterprise file services and cloud storage software. The company is headquartered in Petah Tikva, Israel, and also operates in the United States. CTERA was founded by Liran Eshel and Zohar Kotzer.

CTERA's primary product is a software platform for enterprise file services — combining on-premises edge filers (hardware-agnostic appliances) with a centralized cloud management layer. The platform is designed to replace traditional NAS and file server infrastructure with a hybrid model that stores data in an organization's own cloud environment (public cloud buckets such as AWS S3, Azure Blob, or a private object store) while caching frequently accessed files locally at branch offices. The target buyer is the enterprise IT team responsible for distributed file storage — typically large organizations with many branch locations, such as government agencies, financial institutions, and defense contractors. CTERA sells primarily through channel partners and system integrators.

The main product line is the CTERA Enterprise File Services Platform, which includes CTERA Edge Filers (software-defined NAS appliances deployed at branch sites), CTERA Portal (the centralized management and storage gateway layer), and CTERA Drive (an end-user sync-and-share client). The platform supports deployment on AWS, Microsoft Azure, and Google Cloud, as well as on-premises object storage. CTERA has obtained FedRAMP authorization, which is a significant credential enabling sales to U.S. federal government agencies.

CTERA competes in the enterprise hybrid cloud file storage space alongside vendors such as Nasuni and Panzura, which offer similar global file system architectures. The FedRAMP authorization differentiates CTERA in the U.S. public sector segment.

CTERA's R&D and headquarters operations are based in Petah Tikva. The founders are Israeli, and the core engineering team is in Israel.
