The term “ZTNA,” zero trust network access, has been around for years - first bursting onto the scene in 2017 when Gartner dropped the term in their ZTNA Market Guide. This solution quickly became the starting point for most zero trust projects in the industry since it helped solve a relatively simple, but critical problem - finding more secure ways of providing remote access to internal applications. Unlike VPNs, the promise of ZTNA was to minimize the exposure of apps, keep remote users off the corporate network, and provide application-level segmentation instead of traditional network segmentation.
