Xona is a secure remote access platform built for Operational Technology (OT) and Industrial Control Systems (ICS) environments, operating on a Zero Trust architecture. It is designed to replace traditional VPNs and provide controlled access to critical infrastructure assets for both internal users and third-party vendors or OEMs. The platform targets industries with significant OT/ICS exposure, including energy, oil and gas, manufacturing, government, and healthcare. It addresses use cases such as secure remote access, third-party vendor and OEM access management, compliance and audit requirements, and VPN replacement. Xona enforces Zero Trust principles to ensure that no implicit trust is granted to users or devices, requiring continuous verification before granting access to OT/ICS systems. The platform is intended to reduce operational complexity while maintaining security and compliance posture for critical infrastructure environments.
