ASA 5505, 5510 Base Vs. Security Plus License

The two smallest ASA Firewall models, the ASA 5505 and the Cisco 5510, are the only ones that have two types of licenses. They can be ordered either with a Base License or a Security Plus License.

Many customers of mine are always asking me what the difference is between the two licenses (except from the price of course), so I thought it would be useful to summarize below the differences between the two license types:

10 Maximum VPN Sessions (site-to-site and remote access)	25 Maximum VPN Sessions (site-to-site and remote access)
