Feature Licenses
Security Context Licenses
The Cisco PIX 525 Security Appliance can support up to 50 security contexts, with each context having its own separate security policies and
administrative domain. Several tiers of security context licenses are available for Cisco PIX 525 Security Appliances, including 5, 10, 20, and 50
security contexts. This license is supported by Cisco PIX Security Appliance Software v7.0 and higher, and requires an Unrestricted (UR), Failover
(FO), or Failover Active/Active (FO-AA) license—security contexts are not supported on Restricted (R) models.
GTP Inspection License
The Cisco PIX 525 Security Appliance can provide advanced security services for GTP/GPRS 3G Mobile Wireless environments upon installation of
the GTP Inspection License. This license is supported by Cisco PIX Security Appliance Software v7.0 and higher, and requires either an Unrestricted
(UR), Failover (FO), or Failover Active/Active (FO-AA) license—GTP inspection is not supported on Restricted (R) models.
Encryption License
3DES/AES and DES Encryption Licenses
The Cisco PIX 525 Security Appliance has two optional encryption licenses—one license (PIX-VPN-3DES) enables 168-bit 3DES and up to 256-bit
AES encryption, the other license (PIX-VPN-DES) enables 56-bit DES encryption. Both are available either at the time of ordering the Cisco PIX
525 Security Appliance, or can be obtained subsequently through Cisco.com. Note that an encryption license must be installed to activate encryption
services which are required before using certain features including VPN and secure remote management.
