SASE (Secure Access Service Edge) and SSE (Secure Software-Defined Edge)

Next Generation Networks Security
SASE  and SSE

SASE (Secure Access Service Edge) and SSE (Secure Software-Defined Edge) are two network and security architectural techniques that attempt to enable secure and seamless access to on-premises and cloud applications and services.

Secure Access Service Edge (SASE)
The Secure Access Service Edge (SASE) framework for network architecture combines wide area network (WAN) capabilities with cloud native security technologies in particular, SWG, CASB, ZTNA, and FWaaS to securely link users, systems, and endpoints to applications and services everywhere.

A converged network and security system known as SASE combines conventional network features with security features like firewall, VPN, and zero-trust security in the cloud. With an emphasis on security, scalability, and simplicity, SASE is created to overcome the difficulties associated with swift and safe access to cloud-based applications and services.

SSE (Secure Software-Defined Edge)
The software-defined architecture known as SSE, on the other hand, combines network and security operations into a single platform. Although it offers a flexible and scalable solution for secure access to applications and services, its complete deployment often calls for a combination of cloud, software, and hardware components.

SSE refers to a specific type of network security convergence that incorporates ZTNA, SWG, and CASB/DLP into a single, cloud-native service. Without specifically addressing secure access to WAN resources, SSE offers secure access to the internet, SaaS, and particular internal applications.

SSE is an important component of SASE's security pillar. SASE provides a more comprehensive and holistic approach to safe and optimized access, addressing both user experience optimization and securing all access and traffic against threats, assaults, and data loss.

Users no longer need to connect directly to the corporate network in order to access cloud-based services thanks to SSE solutions' secure connectivity. As a result, there is no longer any need for intricate network segmentation or for exposing an organization's IT infrastructure or applications in an unnecessary manner. 

SSE, on the other hand, securely links users to internet-based apps. SSE can make it easier to monitor apps, devices, and network performance when combined with digital experience monitoring (DEM), which can increase user productivity.

Confused ? What are the Security Service Edge components?

The straight answer is that "the SASE's security element is known as SSE". So SSE has all the security elements but not the network elements there while SASE includes both security and network elements. The components of SSE are:
