What is SASE? Broadening the Horizon for Australian Organisations

What is SASE and its Core Components?

A robust understanding of this framework requires looking at its two main pillars. On the networking side, it incorporates WAN optimisation and SD-WAN capabilities. On the security side, it brings together Zero Trust Network Access (ZTNA), Secure Web Gateways, and Firewall-as-a-Service. All of this is delivered as a unified service to end-user devices, edge computing, and branch offices.

Why the Move to Zero Trust Matters

Critically, the move toward What is SASE is also a move toward Zero Trust Network Access. Also known as the software-defined perimeter, ZTNA is an identity-driven approach. By default, it denies access to a network and data—even from within the office—rather than assuming a device can be trusted. This significantly improves risk management and reduces the impact of potential security breaches.

Orro’s Approach to Connectivity and Performance

Whether your team relies on public cloud, SaaS applications, or traditional apps from the data centre, the “Secure Client to Cloud” framework provides access in a controlled environment. As noted by Gartner, who first defined the term, the convergence of these services is essential for modern enterprise agility.
