Introduction

Despite seismic shifts in IT, the next-generation firewall (NGFW) remains the cornerstone of enterprise network security. In this report, Ovum details the fundamental capabilities of evolving NGFW platforms and how to benefit from NGFW technological and market evolution.

Highlights

  • NGFW technology remains critical to the success of enterprise cybersecurity programs, but CISOs, security architects, and other key stakeholders must understand that the NGFW is becoming much more than a network security appliance.

Features and Benefits

  • Learn why the NGFW will be deployed less frequently as a traditional physical or virtual appliance.
  • Understand the growing role the NGFW will play as an enabler of best-of-breed security architecture integration.

Key questions answered

  • The NGFW will decreasingly exist as a traditional physical or virtual appliance as it adapts to the requirements of the distributed network perimeter.
  • NGFW location and functions make it a natural enabler of homogeneous platform integration enablement among third-party solutions.
