Cisco ASA5520-AIP20-K9 Firewall with Intrusion Prevention

Equipment Overview

The Cisco ASA5520-AIP20-K9 is a purpose-built enterprise firewall appliance that integrates the ASA 5520 security platform with the AIP-SSM-20 intrusion prevention module. It is designed to deliver high-availability stateful inspection, VPN termination, and advanced threat mitigation for medium-to-large network environments. The unit combines firewall, intrusion prevention, and encryption services in a single 1U form factor, supporting both perimeter security and internal segmentation tasks. With four Gigabit Ethernet and one Fast Ethernet interface, it provides robust throughput for mission-critical traffic.

Main Parameters

• Model / MPN: ASA5520-AIP20-K9
• Form Factor: ASA 5520 appliance with integrated AIP-SSM-20 module
• Interfaces: 4 x GE (Gigabit Ethernet) + 1 x FE (Fast Ethernet)
• Encryption: 3DES/AES hardware acceleration
• High Availability: Supported (HA)
• Software: Included security appliance software (SW)
• Security Module: AIP-SSM-20 for intrusion prevention and detection

Key Advantages

This configuration is selected for enterprise projects requiring integrated intrusion prevention without additional standalone hardware. The inclusion of the AIP-SSM-20 module offloads deep packet inspection tasks, preserving firewall performance for filtering and VPN loads. The 3DES/AES support ensures compliance with encryption standards for site-to-site and remote-access VPNs, while the HA capability allows redundant deployment for uninterrupted operations.

Compatibility & Integration

The appliance integrates with Cisco ASA family management platforms and supports standard networking protocols (IP, TCP/UDP, and routing protocols) typical of enterprise LAN/WAN environments. It interoperates with Cisco switches, routers, and other ASA units via the built-in GE/FE interfaces, and the AIP-SSM-20 module is compatible with Cisco IPS management software. The unit adheres to common security industry standards for firewall and IPS deployment, including stateful inspection and VPN tunneling.
