New capabilities help eliminate blind spots and extend secure, identity-based access across operational environments without disrupting workflows—helping secure every remote session, application, and device connected to critical infrastructure

Cyolo, the leading provider of secure remote privileged access for operational technology (OT) and cyber-physical systems (CPS), has announced the launch of several major new capabilities, headlined by Cyolo Third-Party VPN Control (patent pending). This groundbreaking capability within the company’s Cyolo PRO (Privileged Remote Operations) solution delivers visibility and access control for enforced third-party VPN and direct connections without requiring changes to production infrastructure or vendor workflows.

In today’s increasingly connected industrial environments, even organizations with mature security programs face a critical blind spot: third-party connections they cannot govern or even see. Some vendors insist on using their own legacy VPNs, site-to-site tunnels, or proprietary ‘black box’ gateways on OT networks, forcing plant managers and industrial operators to accommodate external methods that operate outside of their control. These opaque and unmanaged pathways pose significant risks, leaving organizations unaware of who is connecting, when, where, and what activities are occurring inside their most sensitive networks.

The new Third-Party VPN Control capability helps close this gap by enabling visibility and access policy enforcement, even when externally managed VPNs or hardware gateways are used.

This Cyolo PRO release includes additional enhancements, each tailored to address critical access and collaboration needs in cyber-physical environments:

• Instant Collaboration Link: A browser-based, one-time secure link, enabling session owners to invite multiple external participants, i.e., vendors, auditors and engineers into RDP, SSH, or VNC sessions including security controls without agent installations.
• Secure Remote Assistance: Native, secure technical support for both user-initiated and helpdesk-initiated assistance sessions, allowing organizations to deliver timely support while maintaining complete security and operational governance.
• Asset Access Hub: Provides a comprehensive view of assets across various business contexts (e.g., function, vendor) and technical attributes (e.g., IP address, zone, access status). This empowers administrators to manage access based on relevant context and quickly assign accurate, role-based permissions.

As always, Cyolo PRO integrates seamlessly with legacy remote connectivity setups and supports Zero Trust principles by segmenting access.

“In today’s virtual environments, third-party vendors are essential for the unbroken continuity of industrial operations and critical infrastructure—both vital for the economy and national security. However, third-party access methods too often introduce unacceptable risks,” said Almog Apirion, CEO and Co-Founder of Cyolo. “We are always thinking about the real-world challenges our customers face and endlessly innovating to solve those problems. This latest advance represents the next step in the transformation of OT and CPS access, making it more agile, secure, and seamless for administrators and end users, without forcing vendors to change the tools they rely upon.”

With these advanced new capabilities, organizations gain:

• Zero Trust for VPNs: Segments and restricts third-party access for approved assets, reducing lateral movement risk.
• Access Visibility: Real-time visibility into incoming access sessions.
• Compliance-Ready Architecture: Aligns with NERC CIP, ISA/IEC 62443, ISA99, and NIST 800-82 standards.
• Broad Compatibility: Integrates with all legacy remote connectivity suppliers.

About Cyolo

Cyolo provides secure remote privileged access for cyber-physical systems. The Cyolo PRO (Privileged Remote Operations) solution enables industrial enterprises to connect employees and third-party vendors to critical assets in ways that are secure, safe, and surprisingly simple.

Cyolo offers stronger security and more control than traditional secure remote access (SRA), while simultaneously improving operational agility and productivity. Cyolo PRO adapts to any environment, deploys without disruptions or infrastructure changes, and offers capabilities such as privileged access controls, zero-trust connectivity, identity-based access for legacy systems, and centralized management across multiple sites.

Former CISO Almog Apirion co-founded Cyolo in 2020. Frustrated by the limitations of existing SRA tools, he joined forces with industry veterans to build a solution that meets the distinctive access needs of OT environments and cyber-physical systems. With headquarters in Israel and a strong presence in the US and EMEA, Cyolo’s network of employees, customers, and partners stretches around the world. To learn more, visit https://cyolo.io.
