Whenyou need a Cisco ASA Firewall

Cisco ASA series firewalls supports virtualization function with Security Context (SC) feature. This means you can partition 1 single physical ASA firewall into couple different virtual firewalls, being very useful in below several scenarios,

1. You are a service provider and want to sell security services to many customers. By enabling multiple security contexts on the ASA, you can implement a cost-effective, space-saving solution that keeps all customer traffic separate and secure, and also eases configuration.

2. You are a large enterprise or a college campus and want to keep departments completely separate.

3. You are an enterprise that wants to provide distinct security policies to different departments.

In real world, the most common scenario that SC feature is necessary are for large enterprise or government organizations, that each division of the organization has totally different security policies.
