Denny LeCompte is the CEO of Portnox, an Austin-based cybersecurity company that delivers cloud-native network access control and zero trust access for enterprises. A former cognitive psychology professor with a Ph.D. from Rice University, he spent two decades in product strategy at IT and security vendors including SolarWinds and AlienVault before taking the helm at Portnox in 2022. Under his leadership the company grew roughly 8x, and he was named a 2025 Cyber Leader of the Year. He writes the widely read 'Access Granted' LinkedIn column, arguing that cybersecurity is as much a human problem as a technical one.
Portnox is a cloud-native access control company that unifies Network Access Control (NAC), RADIUS, TACACS+, and passwordless conditional access for applications into a single zero-trust platform. Founded in 2007 by a team from the Israeli Air Force and now headquartered in Austin, Texas, Portnox removes the appliances, VMs, and specialized staff that traditional NAC requires, letting organizations authenticate users and devices, assess endpoint risk, and enforce compliance across wired, wireless, and remote networks from the cloud. It serves more than 1,000 organizations across healthcare, finance, manufacturing, and technology.
