Accelerated Insights for Cisco Zone-Based Firewalls
Modern network security demands more than static visibility—it requires real-time, policy-aware observability at scale. Cisco’s High-Speed Logging (HSL) delivers rich session data, but without the right tool to interpret that data, critical context can get lost. That’s where LiveNX comes in.
See Firewall Sessions the Moment They Happen
When Cisco zone-based firewalls are configured with HSL, they stream detailed logs of every firewall session—creations, packet drops, alerts/errors, and pass events—to an external collector. LiveNX’s support for Cisco HSL transforms this raw stream into actionable intelligence.
Built for line-rate performance, LiveNX captures and displays every session with complete 5-tuple visibility (the source IP address, destination IP address, source port, destination port, and protocol). Unlike traditional tools that impact performance or require polling intervals, LiveNX leverages NetFlow v9 to receive scalable, low-latency exports from Cisco firewalls.
The result? A real-time view of what your firewall is doing—and how it’s enforcing policies—presented in intuitive dashboards. You can immediately correlate events to zones, traffic classes, and inspection maps. Whether you’re validating a new rule or responding to anomalous behavior, LiveNX brings clarity where it matters most: at the firewall.
How LiveNX Works with Cisco HSL
Here’s how the solution works in practice:
- Cisco routers with zone-based firewalls export event-driven HSL logs using NetFlow v9, capturing session metadata with minimal processing overhead.
- LiveNX ingests these NetFlow streams, enriching them with deep policy context.
- Events are mapped visually to zone-pair relationships, inspection rules, session types, and event classes.
- Dashboards dynamically display source/destination IPs, port usage, and session lifecycles.
LiveNX is optimized for high-volume environments, so performance scales with your traffic. Whether monitoring standard use or managing bursty volumes, your view remains real-time and complete.
Why LiveNX Is Different from Other NetFlow Tools
Many tools can collect NetFlow—but few can understand Cisco HSL the way LiveNX does.
Competitors often treat HSL flows as just another data stream, requiring custom templates or manual scripts to extract value. LiveNX, on the other hand, is natively aware of Cisco’s HSL structure. It doesn’t just parse or store the flows—it transforms them into immediately useful, context-rich visualizations.
That means:
- No scripting
- No guesswork
- No manual correlation of policy maps
You get a solution that is purpose-built for security enforcement and policy observability.

“For security network infrastructure monitoring, observability tools should include appliances such as Layer 4 firewalls, proxies, Layer 7 firewalls, and VPNs.”
