Windows SNTP server has no concept of security. It receives an NTP request and returns an NTP packet. That's it. It is not clear what you mean by secure. Are you asking if they are encrypted, authenticated, or something else? Please note the NTP does not support encryption. What you get with the reference implementation NTP as opposed to SNTP is authentication of the *server*, but that requires several round trips to set up the validation. SNTP is not really meant for that. What you can do is install NTPd on the Server and then use NTPd on the clients. You would need to generated keys that you would need to distribute to each client you want to have authenticate against the server.
