# What is the CTERA CTTP Transport Protocol

CTTP is the CTERA Transport Protocol used between CTERA Edge Filers and CTERA Drive Share/Protect (Agents) and the CTERA Portal. This protocol has been designed to be a secure, WAN optimized transport protocol. ![image.png](https://cdn.document360.io/30792387-cdcb-4791-aa14-94929bbcd3fe/Images/Documentation/image-QSGQ6DKC.png?sv=2026-02-06&spr=https&st=2026-11-11T03%3A53%3A51Z&se=2026-11-11T04%3A53%3A51Z&sr=c&sp=r&sig=epLGRFpZfeJx2MiG2zHz4iF600ealZH5BZ6OCGErl54%3D)
