Benefits of Using NFV with SASE

June 27, 2023  |  Keith Thomas

In today's digital era, businesses actively strive to heighten network agility, boost security, and slash operational costs. Network Function Virtualization (NFV) and Secure Access Service Edge (SASE) stand at the forefront of this revolution, reshaping enterprise networking and security.

NFV breathes new life into traditional, hardware-based network functions, turning them into versatile, software-based solutions deployable on virtualized infrastructure. As a result, businesses cut hardware costs, speed up service deployment, and streamline network management and automation. When you incorporate NFV into your organization's network architecture, you unlock these benefits:

  • Cut hardware costs and physical footprint: Virtual Network Functions (VNF) operate on general-purpose servers, delivering a more cost-effective solution.
  • Scale the edge swiftly: NFV grants networks that frequently or unpredictably change, greater flexibility and agility. You can deploy, modify, or scale them to adapt to shifting demand.
  • Speed up service deployment: Forget procuring, installing, and configuring specialized hardware. Instead, launch VNFs fast and hassle-free to deploy new network services.
  • Enhance network management and automation: NFV management and orchestration (MANO) systems allow central management and orchestration of VNFs, reducing network administration's complexity and manual effort.
  • Decrease energy consumption: NFV consolidates multiple network functions onto shared infrastructure, lowering energy consumption and cooling requirements, contributing to greener and more sustainable operations.

On the flip side, SASE represents a departure from the traditional network architecture that depends on separate devices for each function. It pulls network and security services closer to the edge, providing consistent security policies, better performance, and simplified management. With its flexible, programmable, and secure networking capabilities, NFV is a critical enabler of SASE. NFV and SASE architectures also deliver these benefits:

  • Scalability: As a cloud-based service, SASE and NFV work in harmony to scale up or down effortlessly based on demand, helping organizations adapt quickly to evolving network conditions and requirements.
  • Performance and user experience: SASE and NFV draw network and security services closer to the edge, reducing latency and enhancing performance for users, especially those remote from the organization's data centers or main offices.
  • Consistent security policies: SASE and NFV ensure the consistent application of security policies across the entire network, regardless of users or devices' location. This is particularly advantageous for organizations with remote workers or multiple branches.
  • Cost efficiency: By merging multiple network and security functions into a single service, and on single physical servers, SASE and NFV help organizations slash costs linked to hardware procurement, installation, and maintenance.

The powerhouse duo of Network Function Virtualization (NFV) and Secure Access Service Edge (SASE) empowers modern businesses to amplify their network agility, bolster security, and curb operational costs. Their synergy keeps organizations in step with the fast-paced rhythm of today's digital business landscape, offering a network architecture that is flexible, scalable, secure, and efficient.

Adopting NFV can fuel cost savings, expedite service deployment, enhance network management, and promote sustainability. Simultaneously, embracing SASE can deliver consistent security policies, improve performance, and simplify management, especially beneficial for businesses with a dispersed workforce or multiple branch locations. Together, NFV and SASE form a robust framework for securing and managing modern networks.

The time to integrate NFV and SASE into your network architecture is now. Considering the multitude of benefits they offer, it's not a mere option; it's a strategic imperative to future-proof your network infrastructure. Don't let your current network setup hinder your business growth.
