What is Network Security?

Network security controls are responsible for

  • the maintenance of authorized access to internal and external connectivity between systems,
  • protection against denial-of-service to network functions that support interconnectivity,
  • seemlessly secure Hybrid and complex network architectures where traditional network boundaries are eroding with cloud acceleration, edge integration and 5G adoption.

Why it matters

Most network security controls are a combination of hardware appliance purpose-built for high throughput of traffic and advanced software that are essential to identify malicious activity and respond in near real-time.

The landscape

On the road to Zero trust

With corporate networks, infrastructures, applications and data moving quickly beyond traditional on-premise profiles (e.g. to the cloud, Edge, mobile devices, value-chain partners, etc.), the increasing adoption of Zero Trust architectures and solutions to secure networks is expected.

The end of traditional security perimeters

Traditional perimeter controls are being redefined (e.g., Firewalls, VPNs), or virtualized and optimally delivered as a Service from the cloud. Functional consolidation and virtualization of core capabilities (SASE, FWaaS) is taking place.

The uptake of preventive technologies

Preventive network security technologies that are highly agile and compatible with a wide spectrum of enterprises’ IT infrastructures will have an increasing adoption rate.
