Good day to all,
I'm being asked to recommend the purchase of an ASA for firewall, IPS, and VPN services with the most users count of 400 users out of which 100 clients would use AnyConnect VPN at most. We currently have an ASA 5512-X in production at one of our sites which its sole function is to terminate VPN tunnels for AnyConnect remote clients and it has been working well without any hiccups.
When I reached out to a Cisco partner, I was asked to consider a 5508-X or a 5516-X because as they stated it, the EOL for the ASA 5512-X would come in much sooner than the other two models.
Now even if that were true, while looking at a document posted on another discussion (link below), I saw that the 5516-X is considered a Low-End appliance while the 5512-X is considered a Midrange appliance. Could someone please explain why this is? Being that the 5516-X handles higher connections, higher throughput, it has more memory, and higher specs overall across the board and the only factor I could find where the 5512-X is superior is that it is rated to work at an operating altitude of 15,000m.
