Selection of Firewall

shahid.faisal
Level 1
Level 1

We want to buy a firewall, our requirement is we have an online web application that our clients will access through Internet, these users will not exceed to more than 3,000 in coming 5 years, we are also expecting few site to site VPNs not more than 20 from our world wide clients. We are thinking that we will place our web servers and email server on DMZ, our 100 Users network will connect to internet through inside network, we are also thinking to place our databases and SANs on the third interface and users from the DMZ & LAN will access them through Firewall, and the fourth interface will connect to the outside world.

For the above scenario we have two options (as suggested by a tool Cisco Product Advisor) i.e.

We need an opinion that if you go for ASA 5510 can it cause any bottleneck in the coming 3 to 4 years ?, Memory 256 can cause any problem ?

Thanks & Regards

I believe the latest production of ASA5510 comes with 1GB of memory.

Here is the model comparison for your reference:

From experience, ASA 5510 (with Security plus license) should fit the specification that you have provided.
