Gartner Group has recently published research and thought leadership pieces that discuss SASE (pronounced “sassy”) and why this emerging technology needs to be considered by enterprises operating in the cloud and on the Internet. Its worth a look at the drivers behind SASE and why network decisions should include the SASE concept.
Gartner’s Market Landscape
Traditional network offerings are not suited to delivering reliable, agile, cost-effective and high-performing solutions in support of hybrid cloud IT architectures.
SASE is an emerging offering combining comprehensive WAN capabilities with comprehensive network security functions to support the dynamic secure access needs of digital enterprises.
The secure access service edge is an emerging offering that combines comprehensive network security functions (such as SWG, CASB, FWaaS and ZTNA), with comprehensive WAN capabilities to support the dynamic secure-access needs of organizations.
SASE capabilities are delivered as cloud-based services driven by the identity of the entity, real-time context, organization security/compliance policies and continuous assessment of risk/trust throughout the sessions. Identities of entities can be associated with people, groups of people (branch offices), devices, applications, services, internet of things (IoT) systems or edge computing locations.
SASE is in the early stages of development. Although adoption of SASE will occur over the next several years, successful vendors will be easy to identify within three years.
Both network and security vendors should remember:
It is critical that SASE providers be able to terminate and inspect encrypted sessions, where required, based on policy with a scalable (ideally, software-based) architecture.
Other important services include DNS protection, remote browser isolation, Wi-Fi hot spot protection, traditional VPN services, and web application and API protection services. Some vendors will offer network privacy-as-a service, hiding enterprise network infrastructure from visibility when using SASE services.
The Problem We Solve
Public cloud computing has rendered traditional enterprise wide-area networks (WANs) suboptimal, from a price, performance and security perspective. Software-Defined Wide-Area Networks (SD-WAN) have revolutionized how enterprises manage their wide-area networks. However, SD-WANs increase the enterprise’s public exposure and therefore its cyber profile, rendering traditional security methods inadequate. NetAbstraction provides the protection lacking in the traditional SD-WAN and is the next generation of wide-area networking.
NetAbstraction provides a simple but very effective solution that obfuscates and anonymizes WAN traffic, enables private browsing and privatizes application-to-cloud connections.
While SD-WAN has made the enterprise’s use of their WAN more efficient, it has not solved some of the fundamental issues in today’s WAN. Leased lines and MPLS services are static and make a fixed target for cyber attack. They also limit the ability to elastically meet bandwidth demands. When considering the use of the Internet or cloud, there are significant cost savings, but performance and security are key concerns.
NetAbstraction is a natural fit in Gartner’s new SASE category, providing the network security that enterprises need as part of the digital transformation.
