By default, traffic in a PowerShell Remoting session is encrypted no matter whether HTTP (TCP/5985) or HTTPS (TCP/5986) transport protocol is used. Anyway, all traffic is encrypted using the AES-256 key. However, if you connect to a remote computer outside your AD forest or in a workgroup (Kerberos cannot establish a trust relationship with), you are at risk of man-in-the-middle attacks. Microsoft recommends always using HTTPS transport for PSRemoting when you connect to third-party computers.
