Release Notes:

flexiWAN is the world’s first open source SD-WAN & SASE with a modular and open architecture offered as a cloud service in a SaaS business model.

Version 6.2.1 was released on May, 2023. This version introduces VLAN support, Ubuntu 20.04, Interfaces configuration enhancement and more.

There are three options for hosting flexiManage, each relevant for companies with a different set of requirements. All of these options come with support services and include multi-tenancy.

  • SaaS model in a shared environment - flexiManage is hosted by flexiWAN and includes the flexiWAN logo. This option is great for enterprise deployments and small to medium service provider deployments(Find this option in our pricing under Enterprise SaaS)

  • Dedicated environment - an isolated installation of flexiManage hosted by flexiWAN. In this case you can add your logo to the UI. This is the most popular option for MSPs, Service Providers and SIs

  • Self-hosting - self-hosting of flexiManage is typically best for very large telcos
