Secure access service edge (SASE) is a network architecture that provides a security-focused alternative to SD-WAN. First outlined by Gartner in 2019, SASE converges SD-WAN services with a range of Security-as-a-Service offerings. Gartner now forecasts that by 2024 at least 40% of enterprises will consider adopting SASE.
The leading SASE vendors are a mix of networking incumbents and well-funded startups. These include Cato Networks, Cisco, Fortinet, HPE, Palo Alto Networks, Perimeter 81, Versa, VMware, and Zscaler.
