What are the modern solutions to secure transfer of sensitive email from one company to another? And what kind of prices are we looking at to implement such solutions. Plus what kind of compatibility issues need to be reviewed when implementing this secure transmission from one companies email system to another? Are there any other issues to consider between the 2 parties?
Also, I assume by default email from one companies exchange 2010 > 3rd party exchange 2003 solution won’t have any sort of security like encryption? Or would it?
As a very naïve networking question – if we have one core network but upwards of 30 sites. If email goes from 1 site to another site is that then traversing the internet, or is it still “Internal to internal” traffic? Networking is not my forte.
