# Best OT Security Tools Software *By [Lauren Worth](https://research.g2.com/insights/author/lauren-worth)* Operational technology (OT) security tools are solutions designed specifically for OT environments. OT security vendors develop OT security software to address the unique challenges of OT environments and to secure the tools used in manufacturing, utilities, and other industrial environments. Unlike most traditional IT security solutions, OT security solutions typically use a combination of software and hardware, distinguishing them from other types of security products. OT security tools protect OT environments through access controls, asset and inventory management, network monitoring, intrusion detection, and threat remediation. Security, operations, and IT personnel in industrial environments such as manufacturing, utilities, and various critical infrastructure utilize OT security tools. The OT environment requires special security considerations because of the combination of software and hardware and the difficulties around adapting IT solutions to the OT environment. OT systems typically have long update cycles, making the speed and frequency of IT software updates and patches impractical and making solutions tailored to this unique environment necessary. These products overlap with [OT secure remote access software](https://www.g2.com/categories/ot-secure-remote-access). However, unlike OT secure remote access tools, OT security platforms have advanced threat detection and incident response capabilities. OT security tools are often marketed alongside [Internet of Things (IoT) security solutions](https://www.g2.com/categories/iot-security-solutions). However, the latter supports items such as smart home devices and wearable technology that are not considered operational technologies. There can be some overlap with [industrial IoT software](https://www.g2.com/categories/industrial-iot), but these solutions lack the advanced security features found in OT security tools. Similarly, OT security tools share some functionality with [supervisory control and data acquisition (SCADA) software](https://www.g2.com/categories/supervisory-control-and-data-acquisition-scada), but like industrial IoT, SCADA software lacks advanced security features such as intrusion detection and remediation. To qualify for inclusion in the OT security category, a product must: - Discover and monitor assets, inventory, and networks in OT environments - Detect network intrusions and other security incidents - Respond to vulnerabilities or threats and facilitate remediation ## Category Overview **Total Products under this Category:** 32 ## Trust & Credibility Stats **Why You Can Trust G2's Software Rankings:** - 30 Analysts and Data Experts - 200+ Authentic Reviews - 32+ Products - Unbiased Rankings G2's software rankings are built on verified user reviews, rigorous moderation, and a consistent research methodology maintained by a team of analysts and data experts.

[Industrial Defender](https://www.g2.com/products/industrial-defender/reviews) Industrial Defender is a purpose-built OT cybersecurity platform designed to help critical infrastructure and industrial organizations gain continuous visibility into operational technology environments, reduce risk, and demonstrate compliance without disrupting operations. For nearly two decades, Industrial Defender has focused exclusively on industrial cybersecurity, supporting asset owners across energy, utilities, manufacturing, transportation, and other critical infrastructure sectors. Unlike traditional IT security solutions that struggle in operational environments, Industrial Defender is designed specifically for OT systems where uptime, safety, and reliability are non-negotiable. At its core, Industrial Defender delivers continuous asset intelligence. The platform automatically discovers and maintains an accurate inventory of industrial assets, including control systems, PLCs, HMIs, engineering workstations, and network infrastructure. This visibility extends beyond simple discovery to include configuration baselines, system dependencies, and operational context. Organizations gain a continuously updated view of what exists in their environment, how systems interact, and where risk may be developing. Industrial Defender also provides continuous configuration monitoring, allowing organizations to detect unauthorized or unexpected changes across OT environments. In industrial settings, even minor configuration changes can introduce operational risk or create new cybersecurity exposure. By monitoring configurations over time, Industrial Defender helps organizations maintain system integrity while reducing operational uncertainty. Vulnerability management is another key capability. Industrial Defender correlates asset inventory with known vulnerabilities, helping organizations understand risk exposure across their operational environments. Because industrial systems often cannot be patched immediately, the platform helps organizations prioritize remediation efforts, track risk over time, and document compensating controls. This approach supports both operational continuity and security improvement. Compliance and governance are built into the platform’s design. Industrial Defender supports regulatory and framework requirements such as NERC CIP, IEC 62443, NIS2, and other industry standards. By maintaining continuous documentation of assets, configurations, and vulnerabilities, organizations can demonstrate compliance readiness and reduce the burden of manual audits and assessments. **Seller Details:** - **Seller:** [Industrial Defender](https://www.g2.com/sellers/industrial-defender) - **HQ Location:** Foxborough (Foxboro), Massachusetts, United States - **LinkedIn® Page:** https://www.linkedin.com/company/industrial-defender-inc/ (51 employees on LinkedIn®) ### 20.
