The Cisco Secure PIX Firewall is the dedicated firewall appliance in Cisco's firewall family and holds the top ranking in both market share and performance. The Cisco Secure PIX Firewall delivers strong security and, with market-leading performance, creates little to no network performance impact. The product line enforces secure access between an internal network and Internet, extranet, or intranet links. The Cisco Secure PIX Firewall scales to meet a range of customer requirements and network sizes and currently consists of five models:

  • Cisco Secure PIX 535
    • Intended for Enterprise and Service Provider use
    • Throughput of 1.0 Gbps with the ability to handle up to 500,000 concurrent connections
    • Supports site-to-site and remote access VPN applications via 56-bit DES or 168-bit 3DES
    • Integrated VPN functionality can be supplemented with a VPN Accelerator card to deliver 100 Mbps throughput and 2,000 IPsec tunnels
  • Cisco Secure PIX 525
    • Intended for Enterprise and Service Provider use
    • Throughput of 370 Mbps with the ability to handle as many as 280,000 simultaneous sessions
    • 600 MHz CPU of the PIX 525 can enable it to deliver an additional 25-30% increase capacity for firewalling services
  • Cisco Secure PIX 520
    • Intended for large enterprise organizations and complex, high-end traffic environments
    • Throughput of up to 370 Mbps with the ability to handle 250,000 simultaneous sessions
  • Cisco Secure PIX 515
    • Intended for Small/Medium Business and remote offices deployments
    • Throughput measured at 120 Mbps with the ability to handle up to 125,000 simultaneous sessions
  • Cisco Secure PIX 506
    • Intended for high-end Small Office/Home Office organizations and has throughput measured at 10 Mbps (3DES of 7 Mbps)

All four Cisco Secure PIX Firewall models have IPSEC encryption built-in, permitting both site-to-site and remote access VPN deployments, and operate on a hardened operating system focused on protecting both the security of the device and the networks its protects.

In addition to having the ability to be managed by the PIX Configuration Manager, the Cisco Secure PIX Firewalls also may be centrally managed by the Cisco Secure Policy Manager, which can manage up to 500 PIX Firewalls, Cisco Secure Integrated Software deployments, and site-to-site VPN installations.
