Nowadays, protecting within the organization is table stakes, and we have to go beyond the four walls, we have to go and make sure that not only do we protect our organization, we also have to consider the ecosystem of our partners, the supply chain consisting of other third parties.

So, when we start interacting with APIs, cloud and SaaS models, the overall system is no longer within four walls or defined boundaries.
