Software defined perimeter (SDP) is a security framework that allows hiding both traffic and the IT infrastructure connected to the public internet from interception. SDP interconnects all users (employees, third party) and company assets in a shielded environment on the network layer. This means it only establishes a connection once it has verified the identity of the user and determined if the user device meets the conditions for connecting. An authenticated user does not gain access to the entire network but only to systems they are authorized to work with.
