Download Datasheet

XONA’S frictionless user access platform delivers unmatched security without slowing the speed of work.

XONA Critical System Gateway (CSG) is purpose-built to not only provide simple and compliant access to critical assets but also protect these assets from the specific threats posed by distributed workers and remote work environments. Our platform relies on hardened components, protocol isolation, and encrypted display to securely deliver access to any industrial system or application—enabling business continuity and work-from-anywhere flexibility on demand.



Achieve compliance in regulated industries like energy, finance, healthcare, and government. XONA features are mapped to key regulatory compliance frameworks such as NIST, NERC CIP and ISA/IEC.

Clientless and Browser-Based

Access and maintain XONA CSG from any device—no plug-ins, agents, or clients necessary.

Multi-Factor Authentication (MFA)

Seamlessly authenticate with WebAuthn, U2F, or OTP-compliant hardware tokens or integrate with your legacy MFA solution.

Simple End-User Install

Deploy in minutes to gain near-instant access to critical systems or applications.


Rely on a single, simple, flexible solution rather than multiple point-access technologies.
