Allow only corporate e-mail accounts to be accessed

[armandelli]

Hey folks!

Here we use G-Suite for corporate gmail accounts, acessed via browser through a PFSENSE with Squid(not transparent)+Squidguard and I was wondering: is there way to block, on the pfsense, personal accounts from being used, allowing only specific corporate accounts?

Maybe something that reads the account from the packet payload that is being passed through the ssl connection?
Maybe in Snort?

Tks!

Andre.

I doubt it. That would involve reading the contents of encrypted traffic and then looking up accounts. There is no way pfSense could do that.
