Why we have 2 devices MAG and SA series for SSL VPN ? what are the limitations or technical differences b/w the two types of boxes ?
....desperately need comments on that !
Juniper removed the IVS from the MAG and replaced it with a Service Provider Virtual Machine offering. IVS was really designed for service provider type companies who wanted to offer the SSL solution to multiple customers using a single piece of hardware.
There is no benefit to not having IVS - it is simply that an IVS type solution is now offered via VM based implemention.
