Low encryption models

Some FortiGate models support a low encryption (LENC) license. With an LENC license, FortiGate devices are considered low encryption models and are identified by LENC, for example FG-100E-LENC.

LENC models cannot use or inspect high encryption protocols, such as 3DES and AES. LENC models only use 56-bit DES encryption to work with SSL VPN and IPsec VPN, and they are unable to perform SSL inspection.
