The beginning of an idea
In 2024, Bengaluru—India’s buzzing hub for technology and innovation—saw the birth of Shieldworkz, a cybersecurity company built to address a very specific challenge: the rising vulnerabilities of industrial and cyber-physical systems. The founder, Kiran Zachariah, had a clear vision when creating the company. He wanted to go beyond what traditional IT security firms offered, focusing instead on protecting operational technology (OT), industrial control systems (ICS), and the Internet of Things (IoT). These areas form the backbone of industries such as utilities, energy, manufacturing, and water management, and yet they are often the most exposed to sophisticated cyberthreats.
From the start, Shieldworkz positioned itself differently. It did not see cybersecurity as a set of tools that merely detect and block threats. Instead, it approached the field as a way to create operational resilience. In industries where downtime means more than just lost revenue—where it can affect communities, national grids, or even public health—resilience is everything. Shieldworkz understood this urgency and developed AI-powered solutions that could identify, predict, and respond to threats while keeping operations running smoothly.
The company quickly gained traction. By adopting global standards such as IEC 62443, NIST SP 800-82, and the MITRE ATT&CK® for ICS framework, it demonstrated to industries that it was not improvising but aligning itself with internationally accepted practices. This immediately built trust among operators of critical infrastructure who needed assurance that their security partners were not only innovative but also reliable.
By 2025, Shieldworkz had already made a name for itself beyond India. Its credibility grew in international markets where protecting OT and ICS systems was becoming an urgent priority. With Kiran Zachariah taking on the role of CEO, the company entered its growth phase under a leader who combined business foresight with technical knowledge.
How Shieldworkz helps industries stay secure
What sets Shieldworkz apart is the way it blends consulting expertise with technology solutions. Rather than offering just a product or just a service, it provides both—creating a complete ecosystem of protection for industrial clients.
One of its primary offerings is AI-driven risk assessment. Industrial environments are vast, complex, and full of devices and protocols that behave differently from IT systems. Shieldworkz uses artificial intelligence to analyze these environments, spotting weaknesses that could become entry points for attackers. The system doesn’t stop at highlighting known vulnerabilities; it also learns behavior over time, giving organizations the ability to see unusual activities that might otherwise slip past detection.
The company also specializes in security posture management, ensuring that clients know exactly where they stand in terms of compliance and resilience. For industries working under strict regulatory frameworks, automated compliance checks for standards like ISO 27001 or IEC 62443 are invaluable. They reduce human error, save time, and keep organizations aligned with global benchmarks.
Another major strength is real-time threat intelligence focused on OT/ICS networks. Traditional IT threat feeds often don’t translate well into industrial environments. Shieldworkz creates intelligence streams that specifically track issues like ransomware targeting programmable logic controllers, backdoor exploits in industrial software, and supply chain risks in IoT devices. This gives organizations insights they can actually act upon.
The company’s consulting services and SOC/SOC-as-a-Service offerings complete the package. Many industrial operators—especially mid-sized manufacturers or regional utilities—lack the resources to maintain large in-house security teams. Shieldworkz fills this gap by providing round-the-clock monitoring, incident response, and expert guidance through outsourced or hybrid SOC models.
The Shieldworkz platform itself integrates seamlessly with well-known OT security vendors like Nozomi Networks, Claroty, Dragos, and Honeywell SCADAfence. Built with a passive deployment architecture, it ensures no downtime during setup—a critical advantage for industries that cannot afford interruptions. The system automatically maps assets and communication flows, making the invisible visible. It also supports deep analysis of industrial protocols such as Modbus, DNP3, BACnet, and IEC 61850, offering unmatched visibility into device-level communication.
What makes the platform truly future-ready is its AI-based anomaly detection. By learning the baseline of how machines, devices, and operators behave, it can detect when something deviates from the norm. These deviations might be an attacker moving stealthily within the system or a piece of malfunctioning equipment. In either case, Shieldworkz ensures operators know about it before the issue spirals. To further simplify operations, the platform also generates automated compliance reports and integrates with SOC and SIEM systems, centralizing security management.
A research-driven company
Shieldworkz has shown a strong commitment to research in its short history. In 2025, its Threat Research Lab published a landmark study: the Global OT/ICS & IoT Threat Landscape Assessment & Analysis Report. Based on insights from more than 150,000 honeypots, 20,000 sensors, and 75 incident investigations, the report painted one of the clearest pictures yet of the threats facing industrial systems.
The findings were sobering. The report noted the sharp increase in ransomware attacks targeting industrial environments, emphasizing that attackers understood the leverage they gained when downtime could shut down a plant or disrupt power supply. It highlighted supply chain risks, where adversaries inserted malicious code or exploited vulnerabilities in components delivered by trusted vendors. Perhaps most concerning, it traced the activity of nation-state-backed groups actively probing energy grids and utilities, revealing that geopolitical rivalries were increasingly being fought in the digital domain.
By publishing these insights, Shieldworkz established itself as more than a service provider—it became a thought leader shaping the conversation about OT and IoT cybersecurity. Its research is referenced not just by companies but also by regulators, policymakers, and cybersecurity professionals trying to design effective responses to emerging threats.
Earning recognition in a crowded space
Despite being a newcomer in an industry dominated by established players, Shieldworkz quickly earned recognition. At the Global OT Security Summit (GOTS) in 2025, the company showcased its AI-powered detection and compliance automation capabilities. The reception highlighted how much interest there is in solutions built specifically for industrial networks rather than adapted from IT environments.
The company also used the summit to announce an expansion of its services, moving deeper into sectors like energy grids, large-scale manufacturing plants, and smart cities. This marked a key step in its growth strategy—broadening its portfolio to meet the security needs of increasingly interconnected ecosystems where OT, IT, and IoT overlap.
By participating in global events and showcasing its capabilities, Shieldworkz has managed to stand out as a young but credible innovator, signaling that it is not merely catching up to global leaders but actively contributing to shaping the direction of OT/ICS security.
What drives the company forward
Shieldworkz doesn’t present its mission in corporate jargon. Instead, its purpose is clear in everything it builds: to protect the cyber-physical world using intelligent, AI-powered, and non-intrusive solutions. The emphasis on non-intrusive technologies is especially important. In industrial environments, the last thing operators want is a security tool that disrupts production. Shieldworkz’s approach is to make security seamless, invisible when possible, and proactive always.
Its long-term vision is equally ambitious. The company wants to be recognized as a global benchmark for OT security. Rather than being known only as a solution provider, Shieldworkz aims to set the standard for how industries across the world secure their infrastructure in an era of digital transformation. This vision is as much about shaping the ecosystem as it is about growing its own business.
Where Shieldworkz calls home
Shieldworkz operates from its headquarters in Vaikuntam Layout, AECS Layout, Lakshminarayana Pura, Bengaluru, Karnataka, India. Being based in Bengaluru gives it access to India’s thriving technology ecosystem, top engineering talent, and a growing pool of cybersecurity expertise.
By 2025, the company had built a team of between 51 and 200 professionals, spanning research, consulting, SOC operations, and platform development. This size reflects both agility and diversity—large enough to handle complex engagements, but small enough to remain adaptive and innovative.
Its operations model is designed to scale. Whether supporting a local water utility or working with a multinational manufacturing company, Shieldworkz has structured its teams and services to deliver tailored solutions without compromising quality or focus.
Engaging with the world online
In addition to its research and client engagements, Shieldworkz actively nurtures a digital presence. Through its official website and social media platforms, it shares industry updates, awareness campaigns, event highlights, and expert commentary on threat trends.
This online activity does more than market the company. It helps foster dialogue in the wider cybersecurity community, spreading awareness about OT and IoT threats that are often under-discussed compared to IT security. By maintaining this active engagement, Shieldworkz positions itself as not only a vendor but also a community builder in the industrial cybersecurity space.
