The drive for agility and improved data flow has fundamentally changed the way modern businesses operate. Employees have left the corporate office, working and accessing applications and data from everywhere and at all times. Applications have moved out of the data center and into the cloud in the form of software-as-a-service (SaaS) applications, such as Microsoft 365, and private applications hosted in AWS, Azure, and Google Cloud Platform. Not surprisingly, a majority of companies say their sensitive data is now located outside of the enterprise data center.1 The shift to cloud-based applications has drastically expanded the attack surface, exposing businesses to new threats. Traditional security architectures, focused on protecting the network and users within it, are no longer relevant. To address these challenges, organizations are rethinking 30 years of network and security methodology and migrating to a model based upon zero trust.
