Product Review

The Cisco ASA5555-K9 offers a comprehensive range of interfaces, including eight RJ45 and six optional GE, catering to diverse network requirements. However, its NGFW and NGIPS throughputs are limited to 1.2 Gbps, potentially constraining performance in high-demand environments. Its strong suit lies in its high-capacity handling of concurrent sessions and new connections, supporting up to 1 million concurrent firewall connections and 50K new connections per second, making it suitable for medium to large-sized enterprises requiring reliable security features.


The Cisco ASA5555-K9 is a comprehensive security solution designed to meet the needs of a variety of network environments. This model is part of the Cisco ASA 5500-X Series, which is well-regarded for its performance and flexibility in providing advanced security features. The ASA5555-K9 combines firewall, antivirus, intrusion prevention, and virtual private network (VPN) capabilities. At its core, the ASA5555-K9 boasts a firewall throughput of 4 Gbps, ensuring efficient traffic management and threat mitigation. The Next-Generation Firewall (NGFW) throughput is rated at 1.2 Gbps, and the Next-Generation Intrusion Prevention System (NGIPS) matches this with a throughput of 1.2 Gbps as well. These specifications indicate the device's ability to handle modern security threats effectively. For detailed traffic inspection and control, the throughput with Firewall and Application Visibility and Control (AVC) reaches 1.7 Gbps. When integrating both AVC and IPS, the throughput is capable of reaching 1.2 Gbps with 1024B packet size and drops to 420 Mbps with 450B packet size, showcasing its adaptability to different traffic types and sizes.
  • Maximum Concurrent Sessions, with AVC, are impressive, reaching up to 1 million, which allows for significant scalability in growing network environments.
  • It supports up to 22K Maximum New Connections per Second, with AVC, ensuring rapid adaptability to changes in network traffic patterns.
  • The appliance also offers robust VPN performance with an IPSec VPN Throughput of 700 Mbps, facilitating secure remote access.
In terms of hardware interfaces, the ASA5555-K9 comes equipped with 8 RJ45 ports and has the option to add 6 more Gigabit Ethernet ports, providing flexibility in connectivity. For high availability and redundancy, it supports both Active/Active and Active/Standby configurations, ensuring continuous operation and minimal downtime. The Cisco Firepower Device Manager enables simplified management of the device, providing an intuitive interface for configuring and monitoring the security features. Security contexts are also a key feature, with the appliance supporting 2 included contexts and the capability to expand up to 100, offering multi-tenancy and enhanced segmentation options. The ASA5555-K9 is designed for rack mounting in a standard 19-inch rack with a 1RU form factor, making it suitable for a wide range of installation environments. It operates within a temperature range of -5 °C to 40 °C, ensuring reliability in various operating conditions. In summary, the Cisco ASA5555-K9 is a versatile and efficient security appliance suitable for medium to large-sized enterprises. Its combination of high throughput rates, extensive session handling capabilities, and advanced security features make it a valuable asset for any organization looking to protect its network from contemporary cybersecurity threats.
