An Overview of 10 Managed Security Service Providers Leading the Way with SASE Solutions

Advancements in technology coupled with the growth of cloud computing have sparked a game-changing revolution for businesses. At the same time, the rapid adoption of cloud-based and distributed models has resulted in increasing cyber risks. According to a security survey, 92% of organizations are currently hosting at least some of their IT environment in the cloud. In relation, 79% of companies have experienced at least one data breach in the cloud.

Companies are struggling to gain control of modern security issues relating to the cloud and beyond for many reasons. Traditional network management approaches lack the sophistication to uphold security in complex cloud environments comprised of various SaaS solutions, globally distributed and remote users, IaaS models, and hybrid cloud and on-prem data centers. To reduce the evolving risks related to cloud-based and hybrid environments, companies are opting to incorporate innovative Secure Access Service Edge (SASE) models.

What is SASE, and what are the key components?

Secure Access Service Edge (SASE) is a model originally coined by Gartner in 2019. It encompasses the unification of various network security services such as Zero Trust, CASB and FWaaS, along with WAN functions to provide a single, simplified protection model. As described by Gartner, this provides “the ability to identify sensitive data or malware and the ability to decrypt content at line speed, with continuous monitoring of sessions for risk and trust levels.” One provider describes it as a solution that “unifies networking and security services into a cloud-delivered service to provide access and security from edge to edge — including the data center, remote offices, roaming users, and beyond.”

What are the key benefits of adopting a SASE model?

There are many benefits to adopting a SASE model. One of the most obvious is simplification. The model consolidates various solutions into a single point of service for more efficient management. In addition, this simplicity means better agility, scale, cost savings and coverage across even the most complex organizations.

Adopting a SASE model also significantly increases security by allowing companies to execute on Zero Trust approaches, achieve greater visibility for improved threat detection and response, and enforce critical data and network protection policies to reduce cyber risk.
