Here are a couple of approaches you can try:

1. Double-check Application Control:

    Ensure the Application Control feature is enabled within Sangfor Endpoint Secure.
    Look for a policy specifically to block AnyDesk. You might be able to select it from a pre-populated application database.

2. Consider Alternative Blocking Methods:

    Port Blocking: AnyDesk utilizes specific ports for communication, including TCP 80, TCP 443, and TCP 6568. Blocking these ports on your network firewall (possibly Sangfor NGAF) can restrict AnyDesk functionality.
    Process Blocking: While the blacklist might not work as expected, Sangfor Endpoint Secure might offer options to block specific processes. Explore the possibility of blocking known AnyDesk processes like "anydesk.exe".
