FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
This article explains the limitations of UTM inspection for data exchanged inside an encrypted RDP session.
MS-RDP protocol uses a proprietary form of encryption and therefore the UTM inspection of the data exchanged inside an encrypted RDP connection is not supported by FortiGate.

In such cases, a FortiClient agent installed on the end user machines can prevent the nodes from storing/sharing any suspicious data into the Local and Remote networks. For more information, refer to the product datasheet
