Understanding the FL-4350-PERF-K9 License

The FL-4350-PERF-K9 is a performance upgrade license for the Cisco Firepower 4350 Next-Generation Firewall. It raises the system’s throughput ceiling, expands concurrent session handling, and improves deep packet inspection speeds without requiring hardware upgrades.

In essence, activating this license lets your Cisco Firepower 4350 handle heavier workloads, more users, and larger data volumes efficiently — ensuring that your security appliance continues to perform at enterprise-grade levels as your network traffic grows.

Cisco designed the Firepower series with modular performance in mind, allowing you to scale capabilities through licensing instead of hardware replacement. The FL-4350-PERF-K9 embodies that flexibility, making it one of the most cost-effective ways to future-proof your infrastructure.

Why It’s an Important Upgrade

As networks evolve to support more encrypted sessions, remote connections, and cloud-driven workloads, maintaining consistent performance becomes critical. Without adequate throughput headroom, even the most advanced firewall can become a bottleneck.

Here’s how the FL-4350-PERF-K9 helps solve that problem:

Increases Overall Throughput: Improves data handling speeds for large traffic volumes.

Enhances Inspection Performance: Ensures faster deep packet and intrusion detection analysis.

Optimizes VPN and SSL Handling: Delivers smooth performance for encrypted traffic.

Supports Scalability: Grows with your organization’s expanding bandwidth requirements.

It’s the kind of upgrade that pays for itself — minimizing downtime, improving user experience, and maintaining full-speed security at scale.
