Organizations implementing zero trust network access (ZTNA) are reaping the benefits of empowering remote employees to access resources everywhere using any device, allowing them to stay productive no matter where they work. At the same time, these organizations are boosting their security posture by applying zero trust principles to protect their environments.
Organizations with a hybrid work strategy are bringing some workers back to the office, at least part of the time. According to Gartner, “by 2026, 75% of workers will continue to split time between home and traditional office locations.”* It is time to re-evaluate employee access at a broader scope.
In the legacy on-premises world, access was governed by IP addresses. When employees were physically connected on the corporate network, access controls were accomplished with VLAN, WLAN, ports, switches, and firewall rules. Some implemented network admission control (NAC) as a way to limit or block unmanaged devices from communicating with anything on the local network.
Legacy remote access VPN simply extends the concept by virtually placing the employees’ devices onto the corporate network. Because VPN sessions supply remote devices with IP addresses in the local network, the above controls apply here, too. But whether devices are local or remote, IP-based access control lacks the granularity many companies increasingly expec
