Alexandre makes good points. However, I believe you've started off putting yourself at a disadvantage by not specifying what your requirements are. All good IT decisions come from getting clear on requirements first, not This-product vs. That-product. If both products meet…

@Kowligi Prakash, I looked at FatPipe *years* ago. I was intrigued by the technology, but the leadership I was under at the time didn't see the point. "Just get ISDN BRIs for the branch offices and an ISDN FG D / T1 for HQ."I didn't know you guys were still around! :)

@Sandeep Pandit, there are some legacy Procurve / Aruba switches that are examples. The 2930 series had a single area OSPF.  You were never going to use them as ABR or ASBRs, but they could participate in one OSPF area and had a great price point.

If the main consideration is performance, you won't go wrong with anyone in the Gartner Wired and Wireless Edge Networking Magic Quadrant Leader quadrant, i.e., Aruba / HPE, Cisco, Juniper / Mist, or Aerohive / Extreme I've worked with all of 'em. It's never really the…

Definitely look at Aruba EdgeConnect (formerly known as SilverPeak).  My main client has had them in production for years for five hospital campuses and their headquarters site. They have hardware appliances and Virtual Appliances.Assuming you go the VA route, make sure…

FortiGate. Fortinet is in Gartner Leader Magic Quadrant (MQ).  Sophos is in Niche Player Quadrant if I remember right.  You can never go wrong picking a vendor in the Gartner Leader MQ. Show the Gartner MQ to your leadership to get them on board too.
