How is the Cisco ISR licensed?

Question

Cisco

Actually the question is this:
We are planning to buy a Cisco ISR 1941 router. It comes with IOS 15 UNIVERSAL.
At the time of IOS 12 and the x8xx line of devices, it was more or less clear. There were AdvIPServ, AdvEntSer and AdvSec versions. There is only one version 15 - Universal. What does she know "out of the box" and what do you need to buy in order to resolve 3 channels to the Internet, five internal VLANs, and organize five IPSec tunnels with 1811/2811 ciscos to other offices?
Thank you.

For IPSec, you must immediately take the security bundle. CISCO1941-SEC/K9.
