Enhancing Manufacturing Security with IoT, OT, and Zero Trust Strategies

As the manufacturing sector races ahead in its digital transformation, the intersection of IoT, OT, and security comes sharply into focus. Today, the digital thread runs deep in factories, weaving intelligent automation, connected sensors, and remote operations into a unified tapestry that promises operational efficiency, real-time insights, and global scalability. Yet, as the mesh of connected devices widens, so does the threat landscape. Cybersecurity in this world is no longer a luxury—it's a business-critical necessity.

The Modern Manufacturing Cybersecurity Challenge​

Connected factories, with their complex interplay of IoT and OT, represent both innovation and risk. Every industrial sensor, remote gateway, or programmable logic controller added to a network is not just an enabler of smart production; it's a potential point of cyber vulnerability. Traditional perimeter-based security models, geared for static networks and monolithic enterprise environments, are inadequate against the backdrop of sprawling, adaptive manufacturing ecosystems.
This reality forms the basis for the Zero Trust mantra: trust nothing, verify everything, and never assume safety based on location or previous behavior. Against this backdrop, three industry titans—CyberArk, Device Authority, and Microsoft—have announced a partnership to advance device authentication and access management specifically for manufacturers, aligning with the latest NIST IoT guidelines.

The Convergence of Regulations and Real-World Security​

The National Institute of Standards and Technology (NIST) introduced a reference architecture for IoT security in May 2024, aimed at providing a systematic blueprint for organizations looking to secure their device fleets. The core tenets of the NIST framework—secure onboarding, lifecycle device management, and continuous threat monitoring—reflect an understanding that the manufacturing environment is uniquely dynamic and distributed.
What sets this partnership apart is the explicit goal of transforming these abstract regulatory ideals into deployable, scalable, and efficient security architectures. Manufacturers have long cited ambiguous or fragmented compliance advice as a barrier to robust IoT security. Here, the collaboration between CyberArk, Device Authority, and Microsoft promises a high degree of NIST compliance not as a patchwork of partial solutions, but as a unified, interoperable platform.

Microsoft: The Backbone of Secure Device Management​

Microsoft brings to the table one of the industry's most trusted cloud operational backbones. With Azure IoT and Defender for IoT, manufacturers gain access to device provisioning, configuration, and ongoing management, all underpinned by real-time security monitoring.
A key strength of Azure is its ability to span the continuum from the hyper-connected factory floor to remote, even intermittently connected, edge environments. This is critical—for a manufacturer, a remote pipeline valve is just as business-critical as an assembly-line robot. Microsoft’s cloud-edge integration ensures that the same rigorous security policies and monitoring extend everywhere, not just where network reliability is high.
The implications for manufacturers are profound. They can now achieve visibility and policy enforcement even where devices operate in harsh, isolated, or bandwidth-restricted settings—a fundamental requirement for sectors like oil & gas, pharmaceuticals, and heavy industry.

CyberArk: Enforcing the Principle of Least Privilege​

While device security starts with onboarding, true resilience is tested under live operational conditions. That’s where CyberArk’s privileged access management enters the picture. Manufacturing systems are rife with shared credentials, legacy interfaces, and ad-hoc administrative access—a toxic combination for cybersecurity.
CyberArk automates the enforcement of granular access policies, significantly reducing the human error that plagues manual privilege management. Access to critical devices, whether by employees or machine identities, is stringently controlled and fully auditable. This isn't just about keeping out hackers; it's about closing the everyday security gaps that come from hurried maintenance work, third-party integrations, or emergency troubleshooting.
Furthermore, with modern ransomware and supply chain attacks increasingly targeting the “crown jewels” of operational technology, robust privileged access management becomes more than a regulatory checkbox. It’s an active deterrent to business-disrupting breaches and downtime.

Device Authority: Automating Trust at Scale​

Securing device onboarding and ongoing credential management across thousands—or even millions—of IoT endpoints can teeter on the edge of chaos if not properly automated. Manual processes, no matter how well-intentioned, cannot scale up to meet the speed and complexity of industrial IoT.
Enter Device Authority, whose technology specializes in automating secure onboarding, robust identity credentialing, and seamless encryption. Automating these workflows brings several advantages. It eliminates clerical errors and ensures every device has a unique, verifiable identity. It accelerates incident response when threats are detected, as devices can be rapidly isolated or re-credentialed. And above all, it guarantees data integrity, even when devices are deployed in remote, touch-free environments.

The Edge Problem: Security in the Wild​

Manufacturers operate in some of the world’s most challenging network environments. Edge locations—think remote oil rigs, distributed water management systems, or mobile telematics on fleet vehicles—are hotbeds for cyber risk. Bandwidth is inconsistent, physical oversight is minimal, and real-time business decisions cannot wait for a central cloud system to catch up.
As Darron Antill of Device Authority notes, security at the edge is about more than just device hardening. It’s about guaranteeing operational continuity through unified, autonomous protection mechanisms. The joint solution’s promise is simple, yet ambitious: provide a consistent layer of authentication, encryption, and access control no matter where devices operate, or how often they connect to the mothership.

Unified Security: Moving Beyond Point Solutions​

Perhaps the most consequential shift highlighted through this partnership is the industry’s move away from siloed, piecemeal solutions toward fully integrated, ecosystem-wide security.
Clarence Hinton of CyberArk underscores a critical reality: the sheer scale, heterogeneity, and dynamism of manufacturing networks mean that “bolt-on” security add-ons no longer suffice. Instead, privileged identity management, device onboarding, and encrypted communications must work in harmony, not only covering all devices but doing so seamlessly through a single pane of glass.
This shift has major compliance impacts. NIST guidelines are famously exhaustive, and many manufacturers—especially small and midsize enterprises—struggle to operationalize them without overly complex setups. A comprehensive, joint-industry solution aims to lower the barriers to effective compliance, improving security posture without strangling innovation.

The Business Case: Operational Resilience and Cyber Assurance​

Cybersecurity for manufacturing IoT isn’t just about regulatory requirements or fending off the latest ransomware. It touches the heart of business continuity and brand reputation. A data breach or device compromise could halt production lines, derail entire supply chains, or even endanger safety in sectors like chemicals or energy.
With a unified approach, manufacturers gain not only technical assurance but business agility. Automated onboarding shortens deployment cycles. Real-time monitoring coupled with adaptive access controls minimize the window for malicious exploitation. And regular, auditable compliance checks become a byproduct of everyday operations—not an afterthought when auditors visit.

Strengths of the CyberArk–Device Authority–Microsoft Solution​

Several strengths stand out:
1. End-to-End Visibility and Control
The partnership offers manufacturers holistic oversight of the entire device lifecycle—from initial onboarding to decommissioning. This is not just convenient; it’s necessary for closing gaps where threat actors typically thrive.
2. Scalability Across Device Types and Locations
By leveraging the elasticity of Azure, manufacturers can manage fleets ranging from a handful to millions of devices, distributed globally. Device Authority’s automation ensures the scale does not come with a proportional increase in management overhead.
3. Plug-and-Play Compliance
By aligning practises closely with NIST’s 2024 reference architecture, organizations can have confidence that their security processes map onto U.S. federal standards, which are increasingly referenced in global regulations.
4. Reduced Human Error
Each element of the solution reduces the risk associated with manual processes—be it access management, device credentialing, or incident response.
5. Robust Edge Security
Edge environments receive as much—if not more—protection as core data center devices. This is crucial as critical infrastructure becomes more geographically distributed.

Potential Challenges and Hidden Risks​

No solution, however comprehensive, is devoid of trade-offs or hidden risks. Several points warrant attention:
1. Vendor Lock-In and Complexity
Adopting a tightly integrated solution from three heavyweight vendors can introduce dependencies. Manufacturers may find themselves leveraging Microsoft Azure’s ecosystem to such a degree that switching clouds, or even integrating smaller non-Microsoft solutions, becomes a complex endeavor. Moreover, while the integration multiple best-of-breed solutions offers rich capabilities, it may also present onboarding and training challenges, particularly for organizations lacking deep internal IT resources.
2. The Human Gap
Although automation reduces human error, it doesn’t eliminate the need for skilled administrators and cybersecurity professionals. Well-meaning misconfiguration—either in the cloud or on the factory floor—can still create risk exposure. Furthermore, insider threats (both intentional and accidental) continue to require robust oversight beyond what current automation can achieve.
3. Pace of Regulation vs. Innovation
The NIST IoT architecture is a living document, likely to evolve in response to the rapidly shifting threat landscape. Organizations will need to remain vigilant over time, updating their configurations and policies to stay compliant—not just checking boxes at deployment and walking away.
4. Edge Case Blind Spots
Intermittent connectivity and the diversity of legacy devices in manufacturing environments mean that some endpoints may still fall outside the reach of even the best-integrated solutions. Special attention must be paid to onboarding legacy devices, managing firmware patching, and handling exceptions without opening new vulnerabilities.
5. Cost and ROI
High-touch, high-assurance cyber-physical security systems can be a significant investment, especially for smaller manufacturers. Demonstrating ROI through reduced incidents, streamlined compliance, and operational efficiency will be essential to gaining executive buy-in beyond initial pilot deployments.

The Cultural Shift: Security as a Core Business Function​

The broader implication of this partnership hints at a maturity transformation for manufacturing IT. No longer can security be treated as a bolt-on, overseen by a backroom team disconnected from line-of-business priorities. Instead, cybersecurity must become a boardroom-level discussion, embedded in strategy as a core pillar of operational excellence.
As manufacturing embraces AI, machine learning, and real-time analytics (all of which hinge on trustworthy device data), the need for reliable device authentication and privileged access management will only intensify. Forward-thinking manufacturers will treat these investments not as cost centers, but as enablers of innovation and competitive differentiation.

Looking Forward: The Evolution of Manufacturing Security​

The partnership between CyberArk, Device Authority, and Microsoft points to a future wherein integrated, policy-driven, and scalable security is the default state—not the exception. As new device types proliferate and supply chains grow more complex, the requirements for trusted identity, data encryption, and real-time access controls will only increase.
That said, success for manufacturers will depend on more than technology adoption. It will require a skilled workforce, a culture attuned to cyber risk, and organizational agility to adapt to emerging threats as quickly as they appear.
Organizations that embrace this new paradigm—treating security not as a barrier, but as a foundation for digital growth—will be best positioned to thrive in the connected world.

Final Thoughts​

Zero Trust isn't just a buzzword for the manufacturing sector—it's a survival strategy. By pooling their expertise, CyberArk, Device Authority, and Microsoft are creating a pragmatic, end-to-end security fabric that weaves together compliance, operational resilience, and business agility. Yet, as manufacturers rush to modernize, the journey from guideline to ground truth will require ongoing vigilance, flexibility, and a steady eye on the ever-shifting cybersecurity horizon.
In a world where a single compromised device can jeopardize an entire supply chain, the imperative could not be clearer: cybersecurity for manufacturing IoT must be holistic, proactive, and deeply embedded in the digital heart of the enterprise.

[ChatGPT]

As the digital revolution sweeps through the manufacturing sector, the convergence of Internet of Things (IoT) devices and Operational Technology (OT) has rapidly redefined what factories and supply chains look like. This transformation brings clear benefits—automation, efficiency, and real-time analytics—but it also creates a vast attack surface teeming with new cyber risks. Enhancing cybersecurity for this evolving landscape has become not just a technical necessity but a strategic imperative. This is the context for the recent collaboration among CyberArk, Device Authority, and Microsoft: a partnership geared toward delivering a robust, Zero Trust-based solution for secure device authentication, all underpinned by the latest guidelines from the National Institute of Standards and Technology (NIST).

The New Manufacturing Reality: Efficiency Meets Vulnerability​

Modern factories are no longer isolated fortresses running on a handful of carefully guarded servers. Instead, they are densely populated by innumerable networked sensors, smart machines, and remotely managed edge devices. Each interconnection that brings new insights or optimizes a production line also introduces a fresh potential vulnerability—one that, if left unaddressed, could expose critical systems to manipulation, espionage, or outright sabotage.
This accelerating complexity has prompted the cybersecurity industry to shift focus from perimeter defense to holistic, lifecycle-spanning protection. A device’s journey—from manufacturing and deployment to decommissioning—must now be meticulously secured at each step. The release of the NIST reference architecture for IoT in May 2024 underscores this reality, providing a structured playbook for secure device onboarding, ongoing management, and continuous threat monitoring.

NIST’s IoT Reference Architecture: A Blueprint for Trust​

The NIST framework isn’t just another box-ticking exercise; it’s a comprehensive architecture designed to outpace both evolving cyber threats and increasingly sophisticated attackers. Its guidance extends across the full device lifecycle: onboarding devices securely, authenticating identities, managing privileges, and maintaining vigilance through monitoring and rapid response. The challenge for manufacturers, however, lies in translating these principles into operational reality—especially at global scale and in environments where connectivity is intermittent and devices are widely dispersed.

Why Manufacturers Face Unique Security Hurdles​

The peculiarities of manufacturing compound these risks. Factories bristle with high device density, edge deployments in remote or even hostile environments, and mixed generations of equipment. Network connectivity comes and goes, and the sheer number of devices magnifies the odds that something—somewhere—is unmonitored or misconfigured.
Traditional IT security approaches, which rely on stable networks and centralized monitoring, falter here. Human intervention, while critical for strategic oversight, is often an unreliable linchpin for daily device security: manual configuration is slow, inconsistent, and prone to costly errors. Edge environments in particular represent the “wild West” of connected manufacturing—a place where visibility is limited but the stakes are sky-high.

The CyberArk, Device Authority, and Microsoft Approach​

Recognizing that no single vendor can fully address this challenge, CyberArk, Device Authority, and Microsoft have come together to build an integrated, end-to-end solution architecture. The strengths of each partner come to the fore in distinct, yet interlocking, components:

Microsoft: The Backbone of Secure and Scalable Device Management​

Microsoft’s Azure IoT and Defender for IoT offerings lay the groundwork for scalable management and real-time monitoring. Through tight cloud-edge integration, device security consistency is maintained—even for air-gapped or intermittently connected deployments. With Azure as the backbone, manufacturers gain:

• Centralized visibility into distributed devices,
• Automated, policy-driven updates,
• Rapid threat detection and response across both cloud and edge nodes.

This model is especially valuable when connectivity can’t be taken for granted. It allows security controls and device telemetry to “trickle” to the cloud when possible, but still enforces local policies when outside of network reach.

CyberArk: Privileged Access Management and Zero Trust in Action​

The rise of highly targeted, privilege-escalation attacks demands strict control over who—or what—can touch sensitive infrastructure. CyberArk contributes its industry-leading privileged access management capabilities, enabling manufacturers to:

• Restrict unauthorized human (and machine) access,
• Enforce nuanced access policies down to the device or process level,
• Eliminate or drastically reduce manual intervention in routine device management, and
• Reduce the threat footprint of stolen credentials or insider attacks.

This approach dovetails with Zero Trust principles, where every access request—whether made by a person, a device, or an application—is treated as potentially hostile until proven otherwise.

Device Authority: Automation, Credentialing, and Integrity​

Devices themselves can’t be trusted blindly, either at onboarding or over time. Device Authority’s role is to automate:

• Secure device onboarding,
• Identity provisioning and credential issuance,
• End-to-end encryption of device data.

This automation doesn’t just reduce the burden on already-stretched security teams; it enhances consistency and accelerates incident response. By embedding cryptographic identity and policy from the outset, Device Authority eliminates many avenues for spoofed or rogue devices to insinuate themselves into manufacturing networks.

Engineering Real-World Compliance: NIST in Practice​

It’s one thing to have a reference architecture on paper. The true challenge—one cited by Clarence Hinton, Chief Strategy Officer at CyberArk—is bringing these principles to life across the dispersed, chaotic environments encountered in real manufacturing. Piecemeal solutions and patchwork controls are inefficient at best, and dangerous at worst, often leading to gaps that sophisticated adversaries can exploit.
The trio’s unified approach transforms NIST compliance into an operational reality instead of a compliance headache. By merging device onboarding, credentialing, monitoring, and privileged access management within a seamless architecture, organizations can finally keep pace with the evolving nature of manufacturing threats.

Addressing the Most Pressing Edge Concerns​

As Device Authority CEO Darron Antill emphasizes, edge environments represent the sector’s greatest point of pain. These sites—sometimes hundreds or thousands of miles from a centralized data center—are dense, dynamic, and differently risky. Devices may only connect sporadically; operators may be local, remote, or both; and threats may come from insiders, cybercriminals, or even physical attackers.
Solving for the edge means more than just shipping “smart” software. It requires:

• Automated, error-resistant onboarding and credential management,
• Local enforcement of security policy (even when disconnected),
• Swift, reliable incident detection and response capabilities,
• Continuous integrity monitoring to flag rogue or malfunctioning devices.

The joint solution doesn’t just tighten defenses; it accelerates recovery and closes the feedback loop so that every deployment stays in line with the latest regulatory and operational requirements.

The Drive Toward Operational Resilience​

Manufacturers don’t just want to keep intruders out—they’re looking for operational continuity in the face of any threat. Downtime, whether caused by malware or a misconfigured device, is a direct attack on profitability. The partnership’s focus is therefore not simply on thwarting attackers, but on ensuring that—even if defenses are breached or mistakes are made—factories can absorb shocks and maintain productivity.
By reducing the number of manual security interventions needed each day, the architecture also frees up human staff to focus on strategic priorities, rather than endless, error-prone configurations. This improves morale on the ground and delivers tangible cost savings for plant operators and IT teams alike.

Risks and Limitations: Avoiding Silver Bullet Syndrome​

While the consolidation of expertise from CyberArk, Microsoft, and Device Authority represents a major step forward, it’s crucial to avoid falling for “silver bullet” narratives. The evolving threat landscape guarantees that adversaries will invariably seek weaknesses—be it in software integration, human processes, or legacy devices not covered by the architecture.
Potential risks include:

• Over-reliance on automation or artificial intelligence without adequate human oversight,
• Blind spots introduced by network outages or as-yet-unknown vulnerabilities,
• False sense of security that can arise from vendor marketing overpromising “full” compliance or invulnerability.

Manufacturers embarking on their IoT security journeys must still attend to best practices in staff training, incident planning, and layered defense. Secure device onboarding is necessary, but not sufficient, for comprehensive security; patch management, network segmentation, and process discipline must still be religiously enforced.

A Model for Broader Industry Collaboration​

This partnership also serves as a template for cross-industry, multi-vendor cooperation—a model that may be essential as technology stacks become more interdependent and complex. No single vendor, however ambitious, can credibly keep up with both compliance demands and the day-to-day realities of widely distributed, heterogeneous environments.
The ability to bolt together Microsoft’s cloud and edge capabilities, CyberArk’s identity management, and Device Authority’s automation toolkit demonstrates that open, standards-based architectures have distinct advantages over monolithic walled gardens. It also reassures manufacturers that their investments are future-proofed against sudden shifts in regulatory guidance or cybersecurity threats.

Meeting the Surge in Regulatory Scrutiny​

With legislators and regulators worldwide ramping up their scrutiny of how manufacturers protect connected devices, the demand for NIST-aligned solutions is rising fast. Supply chain transparency, auditability of device activity, and provable enforcement of policy are no longer optional extras—they are essential requirements for doing business, especially in sectors like critical infrastructure, automotive, and healthcare.
By embedding NIST principles into the foundation of their solution, CyberArk, Device Authority, and Microsoft help manufacturers demonstrate regulatory compliance not only for today’s standards but for the inevitable evolution of tomorrow’s requirements.

Looking Ahead: The Future of Secure Digital Manufacturing​

The journey to secure, automated, and resilient manufacturing operations is only beginning. As billions more devices come online, and as attackers become ever more resourceful, manufacturers must constantly raise the bar on their own security posture. The trend to watch is the continuing fusion of automated onboarding, privileged access management, and real-time monitoring—with human expertise still playing a critical, strategic oversight role.
This partnership points toward a future where:

• Devices are securely identified, authenticated, and managed from birth to retirement,
• Human error is minimized, but not eliminated, through smart automation,
• Manufacturing operations remain robust, agile, and competitive—even when threatened by sophisticated cyber adversaries.

The principle is clear: trust nothing by default, monitor everything, and automate wherever possible. The manufacturers who heed this approach will be best positioned to reap the benefits of Industry 4.0, while keeping their operations—and reputations—secure in a world of relentless digital change.
