So we have a sniffer capturing all network data to protect proprietary info. Corporate email is easy to monitor since we operate that server. Users still have personal gmail accounts -- and all those captured packets look like gobbledygook. If a gmail user (assume not https, just http) sends an email saying "our top secret ingredient is chili peppers" why can't I find those packets in my EtherDetect Packet Sniffer? When I test it by sending my own gmail account, I don't find any packets with clear text in them. Is gmail using some new kind of encryption that isnt https but somehow in the body, they are doing all this encryption?
