As the use of business-critical, cloud-based applications and tools continue to increase, distributed organizations with multiple remote offices are switching from performance-inhibited wide-area networks (WANs) to SD-WAN. SD-WAN is a software-defined wide-area network architecture to enable digital innovations. SD-WAN solutions transform an organization’s capabilities by leveraging the corporate WAN as well as multi-cloud connectivity to deliver high-speed application performance at the WAN Edge of branch sites. SD-WAN provides a dynamic path selection between—MPLS, 4G/5G, or broadband—ensuring organizations can quickly and easily access business-critical cloud applications. But SD-WAN solutions don’t provide in-built security which is critical for direct internet access. Secure SD-WAN enables organizations to enable NGFW with SD-WAN in a simplified offering.
With traditional WAN solutions, organizations suffer a less than ideal quality of experience and have a hard time delivering high-performance bandwidth for critical applications. Since legacy WAN architectures rely on packet routing, they lack in-depth application visibility. SD-WAN solutions, however, intelligently identify applications on the very first packet of data traffic. Network teams gain the visibility they need about which applications are used most widely across the organization, which helps them make smarter, more well-informed decisions and policies.
