Once upon a time, cybersecurity teams didn't have to worry about protecting cloud, mobile and IoT technologies, there weren't data breaches every day and phishing emails every moment. Nobody claimed the perimeter was dead—firewalls and airgapping worked just fine—and many security teams only worried about the occasional virus.
