Two shifts—the cloud and mobility—are forcing organizations to rethink how they connect and secure offices, users and resources. If you read this blog post on Secure Access Service Edge (SASE), you’ll have background into this emerging new technology that addresses these changing business dynamics. Let’s go a level deeper to explore how SASE fits into the larger picture when trying to achieve agile, cloud-based security.
When a shiny new technology comes into play, it’s easy to feed into the excitement of using it to master our networking needs of tomorrow. Yet what might get ignored or downplayed are the other factors like security policies and controls that should be incorporated into a company’s network architecture. Overlooking security when moving from centralized to decentralized architectures can lead to additional expenses and security risks later on. That’s where SASE comes in.

SASE over SD-WAN: Stronger together
The industry’s acceptance and adoption of SASE demonstrates the need for “anytime, anywhere” solutions that can deliver secure remote access at scale. We’re watching organizations address these challenges through the combination of dynamic, intelligent network capabilities of SD-WAN with advanced security functions. This lays the foundation for a SASE transformation that can achieve comprehensive protection and necessary compliance for migrations to cloud ecosystems.
SASE and SD-WAN are both networking technologies designed to connect disparate endpoints to a source of data and applications. SASE extends the edge of the private network from end users to cloud service providers and their ubiquitous SaaS applications. It provides persistent connectivity and security wherever an organization’s users and resources are, anywhere in the world. SASE also creates a unified administrative portal that offers complete visibility and control to simplify the management of network and security policies from a centralized single pane of glass.
Because SASE is built upon SD-WAN, users get an efficient and high-performing connection to cloud-based applications. With its ability to link various cloud-hosted services, SD-WAN can be used to deliver dynamic, user-centric SASE security services.

With Zero Trust Network Access (ZTNA), these NSaaS capabilities grant trusted access based on the identity of the user—or application, or other entity—instead of based on their location or IP address as is done by legacy systems.
Plan for a secure future, today
Business is dynamic, and anticipating tomorrow’s networking needs is challenging. Failing to address security in any network migration plan might leave you exposed in the future. For organizations working to address network and security together, the answer may be a robust SASE solution.
