I want to learn the pros and cons of using VPN, MPLS and VSAT technologies. We are planning to connect offices across international locations and want to do a cost benefit analysis considering security aspects as well.
Request you to among other things rate the above mentioned technologies on:
a) security (e.g. VPN :2/10 , MPLS: XX, VSAT: XX)
c) cost (e.g. MPLS = 10 times VSAT etc).
Also, detailed pros and cons of each would be of great help.
