With the increasing complexities of the network environment currently experienced in organizations, users are faced with unique challenges in securing their organizations’ networks without necessarily compromising the availability of various organizational resources.

Meet the Secure Access Service Edge (SASE), a revolutionary network architecture that is making the world of difference. Several SASE trends are in the process of defining how companies should address networking and security issues in the contemporary environment since they provide an ideal one-stop solution to various connectivity concerns.

Definition of Secure Access Service Edge (SASE) 

To those of you who have heard about SASE or Secure Access Service Edge (if you have not, it is okay, let me tell you that SASE is not just the new ‘it’ thing in IT).

It is an umbrella solution that bundles network and security services into one efficient and optimally delivered in the cloud model.

Current SASE trends show a trend in transforming the traditional heavy hardware integrated security solutions to more agile, elastic and customer orientation.

Knowing the risks associated with public Wi-Fi can help in understanding the future trends in Secure Access Service Edge can help in grasping the shift towards more integrated network and security services.

SASE as a Network Architecture 

Secure Access Service Edge (SASE) is a cloud-native model that integrates network and security services into one efficient solution.

It combines WAN capabilities with cloud-native security functions, allowing secure and efficient access to resources regardless of the clients’ location, applications, or data.

Network solutions should not be separated from the security solutions 

The attractiveness of attending SASE is that we can do it as one all-encompassing concept and system, which aligns with the future trends in Secure Access Service Edge.

Organizations are highly likely to reap improved performance, security, and the general ability to manage the complex IT environments — especially considering networking and security as interrelated components. 

Brief history on the evolution of SASE 

SASE was coined by Gartner analysts Neil MacDonald and Joe Skorupa in July 2019. It gained accelerated adoption in 2020 due to the COVID-19 pandemic, which emphasized the need for secure remote work solutions.

By 2021, SASE had further refined with the introduction of Secure Service Edge (SSE). Its popularity continued to grow in 2022 and 2023, and it is expected to sustain growth with advancements in AI and machine learning.
