What Is SASE?
Secure Access Service Edge (SASE) is a network architecture framework that combines a Wide Area Network (WAN) with various cloud native security techniques. These include Firewall as a Service (FWaaS), Security Web Gateway (SWG), Cloud Access Security Broker (CASB), and Zero Trust Network Access (ZTNA).
This joint security approach allows organizations to keep their systems secure while allowing their users and endpoints to connect remotely to their services and applications. SASE capabilities are available as a cloud service to support modern agile development operations, enabling administrators to manage them from a central platform.
SASE is an entire framework rather than a specific technology. Gartner defines this framework as a cloud-based security solution offering holistic WAN and network security capabilities, allowing businesses to meet their dynamic access and security requirements. SASE is not the same as Security Service Edge (SSE), which is a subset of SASE focusing on the security services provided by SASE platforms.
How Has the COVID-19 Pandemic Affected SASE Adoption?
The onset of the coronavirus pandemic in the early 2020s saw businesses scrambling to shift their network security to an outside-to-outside approach that supports the needs of a remote workforce. This approach contrasts with the traditional inside-to-inside networking strategy that only addresses internal resources and users.
A new approach was needed because the traditional remote work mechanism—VPN—is often prohibitively expensive at scale. SASE connects users to points of presence (PoPs) close to their location rather than routing them to a central data center. This mechanism makes SASE useful as an outside-to-outside networking strategy because it can handle critical security and network functions like authentication and authorization.
Gartner expects that close to half of all businesses will adopt a SASE-based approach in the coming years. Companies are unlikely to return to their pre-pandemic business strategies, and the number of employees working from home will likely remain high. Investing in SASE is, therefore, a long-term consideration for most enterprises. Read More...
