I have a customer who want to make sure that end users dont take files off site and email them to third party emails like yahoo, gmail etc. I know i can setup permissions on folders but i want to know if there is a better way. Also i plan on installing a sonicwall tz215 and enable content filtering. but i wanted to know if anyone familiar with sonicwalls if there is a way to prevent someone from using a proxy to bypass filtering and block any third party emails besides their hosted exchange so users cant access them. Also note that the Union is preventing the employer from making employees from signing non compete agreements.
