Modern enterprise security is a complex task of managing constantly changing risks from multiple, varied locations. Perimeter-based approaches have always been a critical part of enterprise network security, but they are no longer relevant to modern applications. Legacy architectures were designed to stop people from getting into a protected network. In modern enterprises, the larger threat isn’t people getting in, it’s large amounts of data getting out. Traditional networks were also created when most people in a company worked directly for that company and did most of their work in a finite number of physical offices. Anyone who has interacted with a modern enterprise knows that hasn’t been the case for decades. In addition, many applications themselves operate outside the traditional firewalls, for example, in public clouds. Smart companies embrace better options for controlling access to applications and data.
