Xona Extends Secure Access Leadership with Enterprise-Scale Governance in v5.4.2 Platform Release
Wednesday, August 13, 2025
New Centralizer interface, multi-site policy control, and federated identity support deliver secure access at scale for critical infrastructure operations.
HANOVER, Md., Aug. 5, 2025 /PRNewswire/ -- Xona, the leading provider of secure access for critical infrastructure, today announced the general availability of Xona Platform v5.4.2, a major update that extends centralized control, unified policy enforcement, and scalable auditability across globally distributed operational environments.
Building on its proven foundation of secure, zero-trust access for OT, IT, and hybrid networks, Xona's v5.4.2 release introduces new Xona Centralizer management features to extend existing enterprise-grade visibility and control across multiple Xona deployments. Combined with cross-gateway access groups, expanded identity provider support, and enhanced session governance, the release equips critical infrastructure organizations to scale secure access--without adding complexity or risk.
"For critical infrastructure operators, the challenge has never been just about remote access, it's about consistent policy enforcement, auditability, and control across a growing number of users, sites, and third parties," said Roger Caslow, CISO at HRSD. "What the market needs are solutions that can scale governance as quickly as operations and do it without adding additional risk or complexity."
Platform Enhancements in v5.4.2
The Xona Platform v5.4.2 introduces key capabilities for managing secure access in complex, multi-site environments:
-- Xona Centralizer: A new centralized management interface that enables
real-time oversight of users, roles, and sessions across multiple
deployments--eliminating silos and simplifying governance.
-- Cross-Gateway Group Management: Administrators can define access groups
once and apply them universally across distributed gateways, reducing
policy drift and configuration overhead.
-- Federated Identity Provider Support: Native multi-domain SAML and LDAP
integration simplifies IT/OT convergence and strengthens identity-based
zero trust enforcement.
-- Enhanced Role and Time-Based Controls: Fine-grained policy management
enables precise access governance by user, site, role, and schedule.
-- Centralized Logging and Session Metadata: Unified activity records and
session logs improve incident response and simplify compliance with NERC
CIP, IEC 62443, and TSA SD2 mandates.
-- Enhanced Connections: WebGL has been added as an option for connections,
allowing customers to take advantage of 3D graphics displays from remote
assets.
-- Multi-monitor VNC Support: Users can now leverage remote multi-monitor
setups with VNC with pan/zoom to view their applications across multiple
displays.
-- Improved UX and Collaboration Tools: Streamlined UI, lower session
latency, and enhanced session handoffs support fast, secure
collaboration between field users and remote OEMs.
-- Customer Branding: Ability for customers to have customized branding
with company logo and favicon support.
-- Cybersecurity Integrations: File uploads can now be automatically
checked against the Palo Alto WildFire cloud malware scanner prior to
introduction to connected assets.
-- International Keyboard Support: Customers can use their localized
keyboard when connecting to Windows-based assets.
Scaling Secure Access for the Modern CI Enterprise
As critical infrastructure organizations expand operations across regions and third-party ecosystems, the need for secure, scalable access control is more urgent than ever. According to recent industry data, more than 88% of industrial organizations cite insecure remote access as a top cyber risk, while ransomware attacks on OT environments have surged over 80% year-over-year.
Xona's v5.4.2 release directly addresses these trends, helping customers:
-- Eliminate the need for vulnerable legacy tools like VPNs and jump
servers in OT environments with a modern, zero-trust access model
purpose-built for critical infrastructure.
-- Maintain consistent policy enforcement across all users--employees,
OEMs, contractors--regardless of location.
-- Strengthen compliance readiness with real-time logging, video session
recording, and centralized audit controls.

Leading organizations across multiple industries trust Xona's platform. Global giants such as GE, Baker Hughes, and Mitsubishi Corporation have adopted Xona's secure access solutions to protect their critical infrastructure.

With v5.4.2, we're giving them the tools to govern access at scale with enhanced auditability, operational agility, and enterprise-wide policy control," said Bill Cantrell, Chief Operating Officer at Xona.
