About Mainsail
Mainsail is creating the most secure edge computing platform. Our next-gen hypervisor Metalvisor is built to secure workloads from the silicon to the application bringing full-stack protection to edge workloads. Metalvisor provides cutting-edge security protections for mission-critical workloads.

Metalvisor
Mainsail’s Metalvisor is a security platform built on Red Hat Enterprise Linux that aims to protect edge workloads that are outside of the enterprise data center or cloud. The platform aims to defend edge workloads against sophisticated cyber attacks by utilizing separation enforced by security functions in hardware and protecting data in all forms: at-rest, in-transit, and in-use. 
It uses a custom separation kernel at the firmware UEFI layer to provide a secure environment below the Operating System. By implementing security at this level, it is able to restrict threats and adversaries that would otherwise be able to bypass traditional security measures and thus offers robust protection against sophisticated cyber attacks. 

A technology initially developed and used in the United States Department of Defense, Metalvisor is now commercially available and uses Red Hat Enterprise Linux as the foundation for orchestration.
