Cyolo Unveils Advanced Capabilities to Strengthen Secure Remote Access for OT and Cyber-Physical Systems
In an era where operational technology (OT) and cyber-physical systems (CPS) are increasingly interconnected, securing remote access has become a top priority for organizations managing critical infrastructure. To address this growing need, Cyolo, a leader in secure remote privileged access solutions, has announced the launch of several groundbreaking capabilities designed to enhance visibility, governance, and security across operational environments. Among these innovations is the patent-pending Cyolo Third-Party VPN Control, a game-changing feature within the company’s Cyolo PRO solution that delivers unprecedented visibility and control over third-party connections without disrupting existing workflows.
Bridging the Visibility Gap in Third-Party Connections
One of the most pressing challenges in today’s industrial environments is the reliance on third-party vendors who often use their own legacy VPNs, site-to-site tunnels, or proprietary gateways to access OT networks. These externally managed connections operate outside the organization’s control, creating blind spots that leave plant managers and industrial operators unaware of who is accessing their networks, when, where, and what activities are being performed. This lack of oversight poses significant risks, as unmonitored pathways can serve as entry points for malicious actors or lead to accidental disruptions.
The new Cyolo Third-Party VPN Control capability addresses this critical gap by enabling organizations to enforce access policies and gain real-time visibility into third-party connections—even when external tools like legacy VPNs or hardware gateways are in use. By integrating seamlessly with existing infrastructure, this innovation ensures that organizations can maintain strict governance over third-party access without requiring changes to production systems or vendor workflows.
Expanding Secure Access Across Operational Environments
Beyond the Third-Party VPN Control, the latest release of Cyolo PRO introduces several additional enhancements tailored to meet the unique needs of cyber-physical environments. These features not only improve security but also streamline collaboration and asset management while adhering to Zero Trust principles:
- Instant Collaboration Link:
This browser-based, one-time secure link allows session owners to invite multiple external participants—such as vendors, auditors, and engineers—into RDP, SSH, or VNC sessions. The feature eliminates the need for agent installations and includes built-in security controls, ensuring that all participants adhere to strict access policies during collaborative sessions. - Secure Remote Assistance:
Designed for both user-initiated and helpdesk-initiated support scenarios, this native capability enables organizations to provide timely technical assistance while maintaining complete security and operational governance. Whether it’s resolving an urgent issue or conducting routine maintenance, Secure Remote Assistance ensures that every interaction remains secure and compliant. - Asset Access Hub:
This centralized dashboard provides administrators with a comprehensive view of assets across various business contexts (e.g., function, vendor) and technical attributes (e.g., IP address, zone, access status). By empowering administrators to assign accurate, role-based permissions based on relevant context, the Asset Access Hub simplifies access management and enhances operational efficiency.
Seamless Integration with Legacy Systems
A key advantage of Cyolo PRO is its ability to integrate seamlessly with legacy remote connectivity setups. This compatibility ensures that organizations can adopt advanced security measures without disrupting established processes or requiring costly infrastructure overhauls. Furthermore, Cyolo PRO supports Zero Trust principles by segmenting access, thereby reducing the risk of lateral movement within networks.
Addressing Real-World Challenges with Innovation
“In today’s virtual environments, third-party vendors play a crucial role in ensuring the uninterrupted operation of industrial facilities and critical infrastructure—both of which are essential for economic stability and national security,” said Almog Apirion, CEO and Co-Founder of Cyolo. “However, traditional third-party access methods often introduce unacceptable risks. At Cyolo, we are committed to solving the real-world challenges our customers face through continuous innovation. This latest advancement represents another step forward in transforming OT and CPS access, making it more agile, secure, and seamless for administrators and end users alike—all without forcing vendors to abandon the tools they depend on.”
Key Benefits of Cyolo’s Latest Capabilities
With these advanced features, organizations can achieve the following:
- Zero Trust for VPNs: By segmenting and restricting third-party access to approved assets, organizations can significantly reduce the risk of lateral movement within their networks.
- Access Visibility: Real-time monitoring of incoming access sessions ensures complete transparency and accountability.
- Compliance-Ready Architecture: The solution aligns with industry standards such as NERC CIP, ISA/IEC 62443, ISA99, and NIST 800-82, helping organizations meet regulatory requirements.
- Broad Compatibility: Cyolo PRO integrates effortlessly with all legacy remote connectivity suppliers, ensuring broad applicability across diverse environments.
