ABSTRACT
Over the last decade, corporate networks have undergone significant changes and have been increasingly reliant on cloud-based services to run their businesses. The Covid-19 pandemic has expedited this pattern. In this scenario, there is a need to provide security to infrastructures in an advanced and integrated way. Gartner invented the term "Secure Access Service Edge (SASE)"to meet the above-mentioned goal. SASE is a single framework cloud-native architecture that integrates various network and security functions. SASE is seen as a new cybersecurity solution that impacted established vendors but has received little academic attention. Therefore, in this paper, we present a Multivocal Literature Review (MVLR) aiming to gather an illustration of SASE, including definition, key characteristics, reported benefits and challenges and, finally, critiques of this new term. SASE is adopting the benefits of cloud approaches adding security to the service, however, challenges remain in several setups, including legacy systems. © 2021 IEEE.
