Secure access service edge (SASE) is a cloud zero trust architecture implementation that serves secure connectivity from a proximate platform typically housed in the cloud. SASE incorporates four formerly discrete security and connectivity functions: secure web gateway, zero trust network access, cloud access security broker, and software-defined wide area networking. SASE deployments have the potential to transform enterprise work. For the modern enterprise, SASE secures connectivity and sets the organization on a secure, scalable operational path to growth. Moving from legacy, hardware-based security to a cloud-based SASE platform solution is no longer a question of if, but when, and for the purposes of this discussion how. Frost & Sullivan spoke with experts from five enterprise security vendors about different operational security models. Those interviewed included: Nathan Howe, Group Vice President for Innovation at Zscaler Tim Roddy, Vice President of Marketing at Open Systems Dan Maier, Chief Marketing Officer at Versa Networks Anuj Dutia, Global Head of SASE Solutions & Services at Versa Networks Jim Fulton, Vice President of Product Marketing at Forcepoint Eyal Webber-Zvik, Vice President of Product Marketing and Strategic Alliances at Cato Networks Greg Duffy, Product Marketing Director at Cato Networks The experts offered specific guidance to enterprise CISOs considering managed vs. unmanaged SASE deployments.
