The security level with Digest depends on the nonce lifetime and reuse 
counter, both of which you can tune to your liking. The shorter those 
are the more secure, up to the point where it is a purely one-time 
token. That said, some clients (most often browsers) have big trouble 
managing nonces in correct order and with dozens of connections open to 
the proxy - and then there are Squid bugs. So tuning those is not as 
easy as it should be.

NTLM does not work over the Internet. Kerberos might, but not very well. 
They are connection-oriented authentication schemes designed for use in 
LAN environments. So for your described situation they are not useful 
even if you were willing to open the ports.
