Selecting the Right SD-WAN Solution

Traditional WAN infrastructure is costly, complex, static, and time and resource-intensive.

Today’s enterprises need WAN architectures that enable them to fully leverage digital transformation, multi-cloud services, and mobility. SD-WAN is a transformative technology because it is rapidly being adopted to take on these modern IT challenges while addressing a host of other important networking and security issues.

SD-WAN vendors deal with these challenges differently, with some being more effective than others. Selecting the right SD-WAN vendor will help simplify WAN operations and increase network performance, reliability, security, and agility.

SD-WAN Key Capabilities

Virtualization of multiple and diverse circuits
Flexible branch deployment options with zero-touch provisioning
Centralized and flexible hybrid WAN management
Sophisticated traffic path selection
Robust branch and cloud traffic visibility
Multi-layered and embedded security
Programmable and automated policy-based architecture

Choosing an SD-WAN Vendor
with Comprehensive Functionality

SD-WAN can be deployed in multiple form factors and provisioned on commodity hardware within virtual machines, containers, or in the cloud, all of which eliminates complex and costly proprietary hardware problems.

Business applications not only reside within corporate data centers, but they are also increasingly in the cloud for flexibility and scalability. When traffic traversing to and from the cloud is required to go through the corporate data center for security, network performance degrades, negatively impacting the user experience. For a secure branch to cloud connectivity, firewalls, access control and filtering, anti-virus/malware, and DNS, are required to protect against threats. Therefore, SD-WAN solutions need to encompass these critical security capabilities to enable the secure branch to cloud connectivity.

For SD-WAN to truly deliver on digitally transforming the enterprise WAN, it must include the following functions:

  • Flexible software that is ready to replace proprietary network and security elements at a lower cost and can integrate with the existing network infrastructure
  • Secure cloud-to-cloud, branch to multi-cloud, and business to multi-cloud connectivity
  • Embedded, robust network and next-generation security features
  • Full multi-tenancy for micro-segmentation of line of business, tenant, and control, with unique policies per segment
  • Context-based network and security policies and traffic steering, based on users, devices, locations, and applications
