What is a software defined perimeter?

Not long ago, to protect their sensitive data and other IT assets, companies struggled to develop a network security architecture that isolated their internal network from the outside world. To achieve this, they often used a firewall (opens in a new tab) to block strangers and allow insiders in and out of the network.

However, this strategy had a fatal flaw, and that is the assumption that all cyber threats lurk from the outside, while everyone who is allowed access to the network can be trusted. This becomes even more true with the rise of cloud computing and the explosion of remote work, which means more and more workers and company resources are coming from outside the traditional perimeter.
