Which SASE Component? — TechKnowSurge

About this interactive

SASE, Secure Access Service Edge, is not one product but a bundle, and the name started at Gartner, which saw vendors grouping the same products and gave the group its own category. It is a buzzword that turned pro. What goes into a SASE product varies, but some components are required. The base is SD-WAN, which interconnects the sites and runs them from a central controller. On top of it come the security services: a secure web gateway, a cloud access security broker, and zero trust network access, often with firewall as a service. Because they come as one package, a new router or laptop added to the network gets all of them without separate setup. This activity sorts jobs among three of them, each taught in this module. SD-WAN connects the sites and picks their links. The CASB covers the organization's cloud services: visibility, threat protection, data security and compliance. ZTNA applies zero trust to internal resources: verify identity and device, grant access to the one resource, and keep checking. To sort a card, ask what the job is about: the links between sites, cloud services, or access to something internal.

What you'll learn

Assign a job in a SASE product to the component that does it: SD-WAN, the base that connects the sites; the CASB, for cloud services; or ZTNA, for access to internal resources
Explain that SASE bundles networking and security services so a new site or client joins with them already in place

Key terms

Secure Access Service Edge: Secure Access Service Edge is a cloud-delivered security architecture that converges wide-area networking with security services including CASB, SWG, and zero-trust network access, providing identity-centric access control regardless of user location or device.
Software-Defined WAN: A virtualized approach to managing wide area network connections using software-defined networking principles.
Cloud Access Security Broker: A Cloud Access Security Broker is a security enforcement point positioned between cloud service users and providers that applies enterprise security policies including visibility, compliance, data security, and threat protection to cloud service usage.
Zero Trust Network Access: A security framework within SASE that grants access to applications and resources based on continuous identity and device verification rather than implicit trust.
