Web- and Browser-Based Access refers to the ability to securely connect to applications, systems, or remote environments using a standard web browser, without installing client software, VPNs, or endpoint agents. This access model leverages modern HTML5 technologies, web-based protocols, and secure session proxying to deliver full-featured remote access within a browser window. It is commonly used in Zero Trust Network Access (ZTNA) architectures, secure remote access platforms, and critical infrastructure settings where minimal endpoint footprint is preferred.
As organizations modernize their remote access strategies, the traditional approach of deploying heavyweight client software, jump servers, or VPNs to each user device is becoming unsustainable. These methods increase IT complexity, create endpoint risk, and often don’t align with the operational realities of OT environments, third-party contractors, or mobile field teams.
Browser-based access removes this friction by enabling secure, zero-footprint access from any device with a compliant browser. This model supports Zero Trust Access, remote desktop connectivity, and third-party access workflows without giving users full network-level access or exposing internal infrastructure. It’s especially valuable in ICS and critical infrastructure settings, where access must be tightly controlled, observable, and compliant with standards like NIS2, NERC CIP, IEC 62443, and TSA SD02E.
By reducing dependencies on endpoint software, browser-based access also improves scalability, accelerates onboarding, and ensures consistent user experience across platforms.
Xona is built from the ground up to deliver secure remote access through the browser; no client software, VPN, or plug-ins required. Users authenticate through existing identity providers and launch sessions to critical OT and ICS systems directly from a secure, browser-based interface. Supported protocols like RDP, VNC, SSH, and web applications are all proxied and isolated from the user’s device, ensuring complete separation between insecure endpoints and operational systems.
This browser-based approach enables secure third-party access, zero trust remote login, and role-based access control without needing to deploy software to unmanaged or contractor devices. Sessions are fully recorded, auditable, and policy-enforced, meeting the most stringent operational and regulatory standards.
Whether your users are in the field, at a vendor site, or working remotely, Xona provides simple, secure, and scalable browser-based access to the world’s most sensitive infrastructure, without compromising speed, safety, or control.
