Modern organizations need robust cyber security to protect their critical systems. At the same time, their security needs to scale performance up or down as network requirements change.

Unfortunately, most organizations still rely on 15+ year old designs that use classic high availability (HA) firewall clustering to achieve a degree of resilience and failover – at the cost of overbuilding infrastructure that sits idle and is more complex.

In this paper, we’ll discuss the challenges in achieving 99.999% resilience and the key benefits of adopting hyperscale network security.

Resilience is a measure of a security system’s ability to maintain critical capabilities quickly and effectively when faced with adverse events and conditions. Implicit in this definition is the idea that adverse events and conditions will occur. Therefore, system resilience is a system’s ability to detect, respond and recover when the unexpected happens.


  • Power, component, or application failures
  • Excessive loads in network traffic
  • Cyber threats or attacks
  • Configuration faults or errors
  • Lost or degraded communication with a connected system
