Secure access service edge (SASE) has generated a buzz over the last couple of years, particularly in light of the pandemic and its associated surge in remote employees. But SASE hasn’t quite materialized in the way Gartner – which first coined the term in a 2019 white paper – initially expected. In particular, there’s been pushback around the idea that SASE should be delivered by a single vendor, as a single integrated cloud service at the network edge.The SASE model combines network security functions with WAN capabilities, delivering the security elements in the cloud and using SD-WAN at the edge or in the cloud. Key security functions include secure web gateway (SWG), zero trust network access (ZTNA), firewall as a service (FWaaS), and cloud access security broker (CASB).To read this article in full, please click here

One of the key selling points of SD-WAN is the ability to use a variety of network transport options. Enterprises can select MPLS, dedicated Internet access, business broadband, or wireless broadband, for example – whatever makes the most sense, technically and economically, for each site that needs connectivity. Cultivating a mix of suppliers can allow enterprises to significantly reduce transport costs as well as improve the flexibility of their networks.The growth in SD-WAN deployments over the last four or five years created a sweet spot for Internet transport aggregators, which, frankly, had struggled to break into the enterprise market when it was dominated by traditional MPLS providers.To read this article in full, please click here
