Zscaler offer a granular and comprehensive cloud-delivered SASE security solution, with added security services and a cloud-based security stack. The offering is an option for clients with large, multinational corporations who require SASE or granular security to secure their SD WAN network. The company also have strong solutions for remote users, as they leverage their cloud capabilities to offer clients remote access via their Work-From-Anywhere solution (see, How does Zscaler support remote users?). Enterprises looking to secure their distributed mobile workforce or SD WAN transformation, moving applications to AWS or Azure and moving to Office 365 may find Zscaler’s offering to be a useful tool in these use cases.
However, caution is advised due to Zscaler’s large amount of service provider and integrator partners, as well as a wide range of SD WAN vendor parters. IT managers will have to choose an SD WAN solution to go with Zscaler SASE, and then a service provider or integrator to provide most overlay services. This is a complex task, but can be simplified by using the Netify comparison tool - give it a try here.
