The IT/OT convergence offers an exciting combination of efficiency and innovation that, until recently, has not been achievable. The convergence of Information Technology (IT) and Operational Technology (OT) not only dissolves the limitations that prevent productivity and growth, it opens a whole host of possibilities for organizations on the forefront of embracing this paradigm shift. While the fusion of these two silos presents numerous benefits, such as streamlined operations and enhanced data-driven decision-making, it also brings forth its own set of challenges.
Security concerns, interoperability issues between traditionally separate systems, and the need for cross-disciplinary collaboration pose hurdles that organizations must navigate. Successfully managing the IT/OT convergence requires an intentional and strategic approach that addresses these challenges to fully realize the potential of a seamlessly integrated infrastructure.
IT vs OT: What is the Difference?
The IT/OT convergence focuses on two distinct components of an organization’s technology infrastructure: Operational Technology (OT) and Information Technology (IT). Generally, both IT and OT provide protection for technological assets, but their distinctions regarding the scope of purpose are marked by the ability each possesses to overcome a unique set of challenges. At their core, OT and IT differ in their primary functions, scope of offerings, and perhaps most notably, in the nature of the systems they manage.
Operational Technology refers to the hardware, and software, that monitors and controls physical processes. Operational technology is most prevalent in industrial settings like manufacturing and energy. Some other industries that rely heavily on OT include healthcare, transportation, and various infrastructural operations. OT is deeply embedded in the day-to-day functionality of critical infrastructure, managing tasks like supervisory control and data acquisition (SCADA), process control, and industrial automation. The primary focus of OT is the protection of individuals, with a secondary emphasis on protecting industrial operations and their assets. As a whole, OT ensures that industrial processes are optimized, reliable, efficient, and safe.
Alternately, Information Technology generally involves data assets and focuses more on the management of computer systems, networks, and software. IT is the backbone of organizational data management, encompassing activities like data storage, retrieval, analysis, and communication. Typically IT systems support business operations, administrative functions, and decision-making processes. Unlike OT, which is primarily concerned with the physical world, IT operates in the digital realm, dealing with information and software applications.
One of the most distinctive differentiators between these two operational offerings is the temporal aspects of these technologies. For example, because delays in industrial processes can have immediate and tangible consequences, OT places a premium on real-time responsiveness. IT, on the other hand, tends to prioritize the efficient storage, processing, and retrieval of vast amounts of data, often in non-real-time scenarios. This difference in temporal sensitivity reflects the diverse priorities and requirements of the industries each technology serves.
Security concerns also differentiate OT and IT. While cybersecurity is a concern for both, the consequences of a breach in OT systems can be more severe. Compromised OT systems can lead to physical damage, environmental hazards, or even the physical harm of employees. Consequently, the security measures employed in OT must address these unique risks, which are often significantly different from those in IT.
As industries increasingly embrace the benefits of convergence between OT and IT, understanding and managing the differences between these two realms becomes paramount. Bridging the gap between the traditionally isolated domains of OT and IT presents challenges but also opens the door to enhanced efficiency, improved decision-making, and a more comprehensive approach to technological advancement. The synergy between these technologies holds the key to a more interconnected, intelligent, and resilient technological landscape.

Challenges in IT/OT Convergence
The new convergence of IT/OT is not without its challenges. In fact, navigating the intricate landscape of IT/OT convergence presents a multitude of potential disruptions that demand strategic finesse.
While the convergence of Information Technology (IT) and Operational Technology (OT) promises heightened efficiency, there are three major stumbling blocks that pose the biggest threat to the seamless integration of IT and OT.
Security risks, technological hurdles, and the human element are all potential issues that stand in the way of seamless IT/OT integration.
Security Risks
When it comes to challenges in IT/OT convergence, security emerges as an authentic concern. As traditionally isolated systems like IT/OT converge, new vulnerabilities are introduced which then have the potential to bring unforeseen consequences. Due to these security risks, bridging the gap between IT’s data-centric approach and OT’s real-time operational focus requires a delicate balance between the two systems, and ultimately the reevaluation of existing protocols.
The integration of IT with OT opens the floodgates for potential intruders to exploit interconnected systems, and potentially disrupt essential services like energy grids and manufacturing plants. The same connectivity that enhances efficiency is also a vulnerability when legitimate cyber threats are not properly accounted for.
Furthermore, the disparity in priorities between IT and OT cybersecurity creates a breeding ground for conflicts. While IT emphasizes confidentiality and data integrity, OT prioritizes real-time functionality and availability. This disparity can result in inadequate protection mechanisms, leaving systems susceptible to attacks.
The proliferation of interconnected devices amplifies the opportunity for cyberattacks. In fact, as the Industrial Internet of Things (IIoT) becomes integral to industrial operations, each connected device becomes a potential entry point for cyber threats. The intricate web of devices, if not properly secured, can cascade vulnerabilities across the entire IT/OT ecosystem.
To navigate this evolving landscape, a holistic approach to cybersecurity is imperative. It necessitates a fusion of IT and OT security strategies, bridging the gap to fortify against emerging threats and ensure the resilience of critical infrastructure in the face of an increasingly sophisticated digital landscape.
Technological Hurdles of the IT/OT Convergence
Interoperability issues (aka technological hurdles) further complicate the convergence journey, especially in regards to legacy systems and their resistance to seamless integration. Furthermore, the clash of cultures between IT and OT professionals amplifies systems barriers, by hindering collaborative endeavors based on industry best practices. Finally, all of these challenges are then heightened by the rapid pace of technological evolution, which creates a technological gap as organizations grapple to synchronize disparate systems.
IT systems often communicate using standard protocols like TCP/IP, while OT systems rely on specialized protocols such as Modbus or Profibus. Integrating these disparate communication methods demands innovative solutions to ensure seamless data flow. Legacy infrastructure compounds the issue, as many OT systems were designed without the foresight for interoperability and therefore lack the capabilities needed for proper integration.
Moreover, the speed of technological advancements introduces a perpetual challenge that will never truly go away. Keeping pace with rapidly evolving IT technologies, while maintaining the reliability of OT systems, demands a nimble approach and continuous education for IT and OT professionals alike.
Essentially, the IT/OT convergence, while full of enhanced efficiency and insights, necessitates overcoming extensive technological hurdles like systems integrations, scalable solutions, and technological evolution to realize its full potential.
The Human Factor
A successful convergence of IT/OT relies on one very important element…the human element. The convergence landscape demands a skilled workforce capable of navigating an IT/OT hybrid domain. Staffing personnel who are adept in both IT and OT proves a formidable task and often requires innovative training initiatives. Regulatory compliance then adds an additional layer of complexity, especially if frameworks are lagging behind the dynamic convergence landscape.
As information technology (IT) and operational technology (OT) converge, the clash between traditionally siloed cultures is a barrier that requires bridging the communication gap between IT professionals and OT experts. While IT professionals prioritize data integrity and network security, OT experts emphasize real-time operational continuity, but finding a common ground is a must for overcoming this particular challenge.
Often, it is a clash of terminologies and priorities that leads to misunderstandings. IT personnel, versed in cybersecurity, may find it challenging to grasp the urgency of immediate, real-world consequences in OT environments. Conversely, OT professionals may resist the stringent security measures inherent to IT protocols, viewing them as impediments to operational efficiency.
This clash demands a paradigm shift in organizational mindset and a cultivation of interdisciplinary skills among the workforce. Companies face the task of fostering a collaborative environment where both IT and OT specialists appreciate the significance of each other’s roles.
Effective training programs and cross-disciplinary initiatives become paramount to bridge the knowledge gap and create a unified workforce capable of navigating the complex terrain of IT/OT convergence.
