What Is Secure Access Service Edge (SASE)?
What Is Secure Access Service Edge (SASE) And Why It Matters
The world of technology that exists today is substantially different from that of only a few years ago. The cloud has changed everything. Mobile phones and devices have allowed users to work from virtually anywhere. Applications that were once hosted within data centers have moved to the cloud. The combination of mobility combined with business applications available in the cloud, from any location, has allowed companies to become more agile and productive. Bandwidth is through the roof and secures encrypted network connections are mandatory. While the revolution driven by SaaS applications provides new possibilities, the challenges they bring to the world of network security are substantial.
What is the Gartner SASE Model?
- Network security architectures that place the enterprise data center at the center of connectivity requirements are an inhibitor to the dynamic access requirements of digital business.
- Digital business and edge computing have inverted access requirements, with more users, devices, applications, services and data located outside of an enterprise than inside.
- Complexity, latency and the need to decrypt and inspect encrypted traffic once will increase demand for consolidation of networking and security-as-a-service capabilities into a cloud-delivered secure access service edge (SASE, pronounced “sassy”).
- Inspecting and understanding data context will be required for applying a SASE policy.
- To provide low-latency access to users, devices and cloud services anywhere, enterprises need SASE offerings with a worldwide fabric of points of presence (POPs) and peering relationships.
