Is Gmail Secure? What About Yahoo Email?

The short answer is yes. However, if you are using Yahoo, it is definitely less secure in my experience.

Here is why I say this, when doing a cross comparison between both Gmail and Yahoo email accounts, I noticed that Gmail completely masks the originating sender’s IP address entirely and everything is encrypted of course.


When testing Yahoo’s email, I was easily able to extract the IPv4 address from the mail headers of the actual original senders HOME IP address. I then used this information to scan the sender’s home network and discover weaknesses in their little LAN (typical COX router/modem combo unit and various IoT devices.

So, tidbit of information, if using free emails, use Gmail!
