I see that Cisco and other major SSL VPN makers offer devices such as Aventail and Juniper which can handle, respectively, maximum of 5,000, 2,000 and 2,500 users concurrently.
For very large enterprises, that's kind of low, isn't it? Imagine I need to make remote access solutions available to everyone work from home during an extreme bad weather day, for example. We have 30,000 users. How can that be handled? In theory I would need to buy 6 appliances to handle this. That's tough. I don't get it why those numbers are so low.
If anyone came accross and handled this scenario please let me know.
