Forrester: “No one has an SDP budget budget, but everyone has a SDP requirement” SDP is all about creating dynamic and secure network segments between a source and destination system. It’s a good concept, but the term “black cloud” is also meaningless without a whole lot more detail, he says. SDP connections rely on strong authentication of users and devices and then enforce access policies based upon identity attributes (i.e.e.), device type, device profile, locations, etc.) and other risk factors.”]
