<\/div>\n

Enterprises over the past several years have embraced SD-WAN for many reasons, including the flexibility of cloud architecture, enhanced security, centralized management of distributed locations, and improved application availability and performance. In turn, the popularity of SD-WAN<\/a> has helped propel interest in secure access service edge (SASE<\/a>), a network architecture that converges connectivity and security services.<\/p>\n

But as IT organizations look to transition from SD-WAN to SASE, they\u2019re finding they may need to do some internal housecleaning first. Having multiple SD-WAN vendors can exacerbate management complexity and represent some hurdles when IT organizations move to adopt SASE. If they want a smooth and successful migration, IT organizations should consider consolidating their current SD-WAN providers, improving collaboration across networking and security teams, and evaluating managed service providers (MSP), analysts say.<\/p>\n

SD-WAN to SASE progression<\/h2>\n

The SASE model combines network security functions with WAN capabilities, delivering the security elements in the cloud and using SD-WAN<\/a> at the edge or in the cloud. Key security functions include secure web gateway (SWG), zero trust network access (ZTNA<\/a>), firewall as a service (FWaaS<\/a>), and cloud access security broker (CASB).<\/p>\n

Interest in SASE is increasing as IT organizations look to reduce management complexity while securing multiple, disparate end users.<\/p>\n

\u201cEnterprise IT generally wants to find efficiencies in managing their environments, and any way that can simplify complex networks is worth evaluating,\u201d says Brandon Butler, research manager for network infrastructure at IDC.<\/p>\n

Networking and security vendors have moved into the SASE market, some with an SD-WAN foundation and others with a security background. Some vendors provide the full set of SASE features<\/a>, and some players piece together services from various partners. Example SASE vendors include Barracuda Networks, Broadcom, Cato Networks, Cisco, Citrix, Cloudflare, Forcepoint, Fortinet, Juniper Networks, Palo Alto Networks, Versa Networks, VMware and Zscaler, among others.<\/p>\n
