The convergence of Information Technology (IT) and Operational Technology (OT) is transforming the industrial landscape, bringing efficiency and innovation while introducing a complex array of cybersecurity challenges. In an era where industrial IoT (IIoT) and OEM equipment are increasingly interconnected, the need for secure remote access has never been more critical.
This blog explores the challenges of secure remote access, the limitations of traditional security approaches, and the transformative role of Zero Trust security models, with a focus on Invisinet’s innovative solutions.
Challenges in Secure Remote Access
The Risks of Remote Access
Traditional methods for OEM equipment maintenance, such as on-site truck rolls, are increasingly being replaced by remote access for improved efficiency. However, this shift also introduces significant cybersecurity risks. In IT/OT converged environments, network-connected devices accessible remotely become prime targets for sophisticated cyberattacks. In OT systems, these breaches can lead to severe operational disruptions, financial losses, and safety hazards.
Cybersecurity Trends in 2024
The latest 2024 cybersecurity trends reveal a sharp rise in threats to OT environments. According to a report by Gartner, over 30% of cyberattacks in 2024 targeted OT systems, up from 20% in 2022. These attacks have grown more sophisticated, leveraging vulnerabilities in remote access protocols and targeting weak identity verification mechanisms. This evolving threat landscape underscores the need for more advanced security measures.
Limitations of Conventional Security Measures
Inadequacy of Legacy Security Models
Conventional security measures, such as credential-based access and Multi-Factor Authentication (MFA), have proven insufficient in the face of modern cyber threats. While useful, these methods fail to address the inherent vulnerabilities of remote access systems in IT/OT environments:
- Firewall Ports Vulnerabilities: Opening firewall ports for remote access increases exposure to unauthorized access and human error.
- Static Credentials: Even with MFA, static credentials can be stolen or misused.
- Lack of Granular Access Controls: Conventional models often lack the ability to limit access to specific devices or sessions, increasing the risk of lateral movement within networks.
Invisinet: Redefining Secure Remote Access with Zero Trust
Invisinet’s Zero Trust cybersecurity solution addresses the limitations of traditional security models by implementing the "never trust, always verify" principle. This approach is particularly effective in IT/OT environments, where seamless yet secure remote access is critical.
Key Features of Invisinet
- Virtual Air Gap: Invisinet eliminates the need to open firewall ports, ensuring secure remote access without exposing the network to unauthorized traffic.
- Identity-Based Micro-Segmentation: By enforcing identity verification at the network session setup, Invisinet ensures that remote personnel can access only their designated devices, preventing lateral movement.
- IP Address and Server Cloaking: Invisinet cloaks IP addresses and servers both internally and externally, including in the cloud. This ensures that critical resources are invisible to unauthorized entities and can only be accessed by highly secure Zero Trust identities.
- Granular Audit Trails: Invisinet provides detailed records of all network interactions, enhancing operational transparency and simplifying access management.
- Scalable Implementation: Invisinet’s solution integrates seamlessly with existing IT and OT systems, enabling organizations to deploy advanced security measures without disrupting operations.
- Identity-Based Micro-Segmentation: By enforcing identity verification at the network session setup, Invisinet ensures that remote personnel can access only their designated devices, preventing lateral movement.

- Scalable Implementation: Invisinet’s solution integrates seamlessly with existing IT and OT systems, enabling organizations to deploy advanced security measures without disrupting operations.
Implementing Zero Trust in IT/OT Environments
The Role of Identity-Based Security
Adopting Zero Trust in IT/OT environments involves assigning unique identities to every user, device, and session. These identities are rigorously verified before access is granted, ensuring that only authenticated entities can interact with critical systems.
The Importance of a Virtual Air Gap
Invisinet’s virtual air gap creates a secure separation between IT and OT systems without requiring physical disconnection. This protects critical infrastructure from external threats while maintaining the operational efficiency of interconnected systems.
Use Cases for Invisinet
- OEM Equipment Maintenance: Secure remote access for technicians maintaining industrial equipment without exposing the broader network.
- IIoT Device Management: Enforcing granular access control to ensure that IIoT devices are securely monitored and managed.
- Critical Infrastructure Protection: Safeguarding energy, manufacturing, and transportation systems against cyber threats.
Conclusion
As IT and OT systems continue to converge, secure remote access has become a cornerstone of modern cybersecurity strategies. Traditional security models can no longer address the complexity and sophistication of today’s cyber threats. The adoption of Zero Trust principles, particularly through innovative solutions like Invisinet, is essential for organizations seeking to protect their critical infrastructure and maintain operational resilience.
For organizations concerned with network security in supply chain or OEM equipment management, Invisinet’s Zero Trust solution offers a proven path to enhanced security. By combining identity-based access controls, micro-segmentation, and virtual air gaps, Invisinet delivers a comprehensive framework for protecting IT/OT environments in a rapidly evolving threat landscape.
