just wondering whether the objective is to monitor the status or deploying configuration modification and updates.
for monitoring purpose only, a snmp server is all required.
for a complete management solution, cisco has a product called ciscoworks vpn/security management solution (vms).

may i suggest that if you are interested in the vms, it would be better if you can wait for couple more months as a new product namely security manager will be released. this product is going to replace vms eventually.
