We are looking for client-less VPN solutions, likely SSL-VPN to provide web access to our application. These are some backgrounds:
1. We already have several PIXes in place for security control and site-to-site VPN, as well as a few software VPN clients.
2. We have absolutely no need for Anti-whatever protection on the device - anti-virus, anti-spam, etc.
That being said, I have looked at both the ASA and VPN Concentrator from Cisco since we have traditionally been a Cisco shop. To my understanding both of them have native SSL-VPN support, but what I needed some advise is pricing.
For example, if I understand correctly the ASA only comes with certain number of SSL-VPN license. So, say if I buy a ASA 5520 at $6k (CDW), even though it supports "up to 750 SSL-VPN clients", I will still have to pony up $5k or so to buy license packs for every 100 concurrent SSL-VPN connection, right? So in reality if I want an ASA 5520 to support 300 concurrent SSL-VPN connection, I will be paying $6k for the unit plus $5k x 3 for SSL-VPN licnese, which puts me at $21k?
Now, if the above assumption is correct, is it also true that Cisco Concentrators comes with all the SSL-VPN licenses when you buy the box? For example, the CVPN3030 ($19k, CDW) is rated for up to 500 SSL-VPN connections, and to my understanding as long as I buy a CVPN3030 device, I can let 500 users connect to it via SSL-VPN immediately? Is there anything else I needed to add for that to happen?
Basically, I wanted to find out what is the cheaper way to get this done, making sure I understand their licensing policies correctly. I was under the impression that for 300 SSL-VPN users, since we don't need the other security features of the ASA, it would be cheaper for us to just buy a Concentrator 3030 at $19k (not to mention if we need to go to 400 or 500 users, the ASA would be another $10k in the hole). Also there are 3030s on eBay for much less...
Any advise regarding these two devices (or third party alternatives that performs well at a good price point) would be greatly appreciated. Please feel free to share your experience, tips, catches, etc. I am open to idea, and all are welcome!
