-Supports four licensed levels of security contexts: 5, 10, 20, and 50 (the maximum number of contexts supported is based on the Cisco ASA 5500 Series model).

Security Context Licenses
The Cisco ASA 5520 and 5540 can support up to 10 and 50 security contexts, respectively, where each context has its own separate security policies and administrative domain. These appliances include two contexts by default, and those contexts can be used for either Active/Active high availability or virtual firewall services. Several tiers of security context licenses are available, including 5, 10, 20, and 50 security contexts. This license type and related feature set are not supported on the Cisco ASA 5510.
