Industry 4.0 and IIoT: Transforming Connectivity
In the rapidly evolving landscape of Industry 4.0 and the Industrial Internet of Things (IIoT), secure, bidirectional data connectivity is crucial for optimizing operations, improving efficiency, and meeting sustainability goals. Traditional approaches, dominated by VPNs and complex networking setups, are increasingly inadequate for modern manufacturing needs. NetFoundry offers a transformative solution—replacing VPNs with secure, bidirectional zero trust networking, enabling manufacturers to achieve unparalleled levels of security, efficiency, and connectivity.
The Need for Bidirectional Data Connectivity
Manufacturers and service providers supplying software, machinery, and services now require two-way (bidirectional) data connectivity between their networks and the operational technology (OT) networks operated by manufacturers. These connections are essential for a variety of Industry 4.0 and IIoT initiatives, including:
- Improving Product Quality: Enabling inspection, data analysis, and real-time adjustments through feedback loops.
- Optimizing Energy Use: Facilitating energy consumption adjustments, load balancing, and the integration of renewable energy sources to meet sustainability goals.
- Boosting Efficiency: Deploying AI-driven insights to software and machinery within OT networks.
- Enhancing Supply Chain Optimization: Enabling bi-directional communication between OT systems, IT systems (e.g., ERP), and partners for more synchronized supply chain management.
- Improving Security: Applying patches and enhancing incident response capabilities to strengthen security postures.
- Optimizing Production Schedules: Providing real-time updates to optimize scheduling and improve operational agility.
- Facilitating Smart Manufacturing Initiatives: Supporting robotics, automation, and semi-autonomous production lines central to Industry 4.0.
The Business Problem: The Limitations of VPNs and Traditional Networking Solutions
Historically, achieving secure bidirectional data flows involved a complex web of VPNs, firewall ACLs, and intricate IP routing setups. These traditional methods were not only costly and difficult to manage but also increasingly fail to meet modern security, compliance, and regulatory requirements.
The reliance on VPNs for multi-network connectivity comes with inherent risks and complications. VPNs expose inbound ports, creating attack surfaces that can be exploited, while also complicating the setup and maintenance of secure connections. Moreover, traditional approaches are not designed to scale with the rapidly expanding connectivity needs in Industry 4.0 environments, which demand dynamic, high-performance, and multi-protocol solutions.
The NetFoundry Solution: Simplifying and Securing Industrial Connectivity
NetFoundry addresses these challenges with a software-only solution that replaces traditional VPN-based multi-networking setups. Our platform enables secure, bidirectional, high-performance connectivity that adheres to all regulatory, compliance, and security requirements without the complexity of VPNs. Here’s how:
- No inbound ports required: Similar to unidirectional technologies like data diodes, MQTT, CoAP, and Kafka flows, NetFoundry’s solution does not require open inbound ports in either OT or IT firewalls. This outbound-only approach maintains a secure perimeter while facilitating bi-directional data flows, ensuring compliance with Purdue principles.
- Multi-network capability without VPN overhead: Unlike single-WAN solutions (SASE, ZTNA, SSE, etc.), which focus on specific segments, NetFoundry’s zero trust architecture supports full mesh connectivity across multiple networks. This allows any protocol to operate seamlessly, enabling complex data flows necessary for AI-driven optimization, quality assurance, and automated production lines.

Dynamic, full-mesh connectivity: The platform supports the dynamic, multi-protocol connectivity required for next-generation smart manufacturing. Whether it’s real-time data exchange for predictive maintenance or synchronizing production schedules, NetFoundry offers a secure and flexible solution.
Embedding Secure Connectivity in OT and IIoT Products
As Industry 4.0 evolves, product manufacturers of OT equipment and IIoT solutions can lead the way and must integrate secure, bidirectional connectivity directly into their products. NetFoundry’s embeddable zero trust connectivity enables product companies to do this using secure networking SDKs, offering a superior alternative to traditional bolt-on methods like VPNs. By designing secure networking capabilities into their products, solution providers can ensure optimal performance, security, and compliance, supporting real-time data flows and advanced capabilities in modern manufacturing environments. This built-in approach allows providers to lead the transition to Industry 4.0, delivering smarter, resilient products optimized for customer deployments.
Why ‘Outbound Only’ Matters for Bidirectional Flows
NetFoundry’s approach is fundamentally different from traditional VPN and single-WAN solutions. By supporting outbound-only connectivity, we eliminate the need for open inbound ports, which is crucial for bidirectional data flows. While other solutions may use outbound-only for one-way flows, NetFoundry extends this principle to full mesh, bidirectional setups. This allows data to securely flow both ways, crucial for applications like AI model updates, remote monitoring, and ERP integration—all while maintaining the highest security standards.
Transforming Manufacturing Operations
With NetFoundry’s secure, bidirectional zero trust networking, manufacturers can fully embrace Industry 4.0 and IIoT initiatives. By providing a platform that supports secure, dynamic, and efficient connectivity without the need for legacy VPNs, NetFoundry empowers organizations to:
- Drive continuous improvement in product quality
- Optimize energy use to meet sustainability targets
- Enhance efficiency through AI and automation
- Improve supply chain synchronization
- Bolster security and incident response capabilities
- Accelerate smart manufacturing and robotics deployment
Empowering the Future of Manufacturing with Zero Trust Networking
The future of manufacturing relies on secure, flexible, and scalable networking solutions. NetFoundry’s software-only platform provides bidirectional zero trust connectivity that eliminates the need for VPNs, supports the latest Industry 4.0 and IIoT applications, and enhances security and compliance. By replacing outdated, complex networking setups with a modern, zero trust approach, we empower manufacturers to unlock new efficiencies, optimize production, and achieve sustainability goals—all with a simplified and secure network architecture.
