Metavisor: The Heart of Bracket Security Software

Enabling all the functionality of Bracket Security Software is the Bracket Metavisor, an advanced virtualization technology that provides enterprise IT controls within any cloud. Running between the guest OS and the cloud hypervisor, the Metavisor virtualizes I/O functions, thereby enabling the transparent insertion of security services.

Since the Metavisor lives apart from the guest OS in an isolated memory space, it combines the granularity of a host-based security solution with the transparency and immutability of a network-based solution. By deploying security services at this level, the Metavisor acts as the enterprise’s virtual perimeter.

Bracket’s Metavisor chain-loads an unmodified guest OS before starting it and monitors the guest OS throughout its lifetime. Completely transparent, the Metavisor presents itself to the guest OS as the cloud hypervisor, and to the cloud hypervisor as the guest OS.

Built for the hybrid cloud, the Metavisor provides the strongest possible protections for your servers, networks, and data.

Uniquely Positioned for Transparency

The Metavisor sits between the guest OS and the cloud provider’s hypervisor, transparently inserting a single set of IT security controls. A virtual NIC, a virtual storage controller, and a virtual memory controller, the Metavisor ensures IT control without burdening developers.

Operational Simplicity

The Metavisor provides operational simplicity by acting as a single insertion point for IT security controls such as server protection, network micro-segmentation, data protection, and more. IT can thus ensure consistent security policies across hybrid cloud environments. The Metavisor works with existing enterprise IT and cloud management applications and tools to eliminate the need for custom APIs.

Designed for Production Workloads

The Metavisor sits in the data path and virtualizes only the system I/O, thereby avoiding the nested virtualization problem of compounded context switches. Supported by Intel chip sets, this approach lets the Metavisor run large-scale production workloads.

Your enterprise is ready for the cloud. Now the cloud is ready for you.
