SA520 Vs. ASA 5505

[adamvayle]

Can someone tell me the primary differences between the Cisco SA500 series and the ASA 5000 series.  I'm trying to determine which security appliance to utilize in front of a Cloud PBX.  Essentially, the Cloud PBX provider's point of demarcation would be a Cisco IAD (in this case it would be a SIP trunk).  I'm trying to figure out whether to use an SA520 or an ASA 5505 in front of this IAD before connecting to the managed network swtich.  I'm told any firewall used needs to be SIP-aware.  Would either of these work?  When would it be better to use one over the other?  There will only be about 7 users on the network.

Thanks,

Adam V.

ASA5505 has sip inspection and will be ideal for the 7 users that you are talking about. You can configure one of the ports for a certain vlan and connect a router directly to this unit. You can see a sample ASA5505 configuration here:
