De-perimeterization is protecting an organization’s systems and data on multiple levels by using a mixture of encryption, secure computer protocols and secure computer systems. CISOs are looking for someone (anyone!) to step up with a reference architecture they can evaluate and emulate. With BeyondCorp, all users and devices reside on a quasi-public network, so no LANs, VPNs, etc., and all users must be authenticated before being granted access to applications and IT services. Other security vendors offer a variety of tools and technologies that can fit into a similar perimeter-free architecture.”]
