Enterprise interest in Zero Trust Network Access (ZTNA) has soared over the past two years among organizations trying to enable secure anywhere, anytime, any device access to IT resources for employees, contractors and third parties.

Much of this interest has stemmed from organizations looking to replace VPNs as the primary remote access mechanism to their networks and data. But it is also being driven by organizations seeking to bolster security in an environment where enterprise data is scattered across on-premises and multi-cloud environments, and being accessed in more ways than ever before.

"There are two kinds of firms adopting Zero Trust," says David Holmes, senior analyst at Forrester Research. "The work-from-home exodus of the pandemic overloaded many corporate VPNs, causing IT to reach for Zero Trust Network Access solutions primarily as a VPN replacement," he says.

While ZTNA is primarily a security approach, half of the organizations that Forrester encountered adopted it for performance, citing the latency of their VPN technology "You could legitimately say that remote work was the killer app for Zero Trust over the last two years," Holmes says.

The second kind of organization that Forrester has begun seeing more of recently are those taking a strategic approach to Zero Trust and using it to secure access to their network, applications, and data, he says. "Many federal agencies have a mandate from last year’s Biden Executive Order and we’re working with many of them to create roadmaps to increase their Zero Trust maturity," he adds.
