# Best OT Security Tools Software - Page 2 *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 ## How Many OT Security Tools Software Products Does G2 Track? **Total Products under this Category:** 31 ### Category Stats (Jun 2026) - **Average Rating**: 4.5/5 The average rating of products in this category, based on all submitted ratings *Last updated: June 23, 2026* ## How Does G2 Rank OT Security Tools Software Products? **Why You Can Trust G2's Software Rankings:** - 30 Analysts and Data Experts - 200+ Authentic Reviews - 31+ 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. Each product is measured using the same transparent criteria, with no paid placement or vendor influence. While reviews reflect real user experiences, which can be subjective, they offer valuable insight into how software performs in the hands of professionals. Together, these inputs power the G2 Score, a standardized way to compare tools within every category. ## Which OT Security Tools Software Is Best for Your Use Case? - **Easiest to Use:** [Palo Alto Networks IoT/OT Security](https://www.g2.com/products/palo-alto-networks-iot-ot-security/reviews) - **Best Free Software:** [Palo Alto Networks IoT/OT Security](https://www.g2.com/products/palo-alto-networks-iot-ot-security/reviews) ## What Are the Top-Rated OT Security Tools Software Products in 2026? ### 1.

[Seclab Xplore](https://www.g2.com/products/seclab-xplore/reviews) Seclab Xplore is a non-intrusive OT visibility and detection solution for industrial networks and critical infrastructure. The solution generates five distinct mapping views from a single data source: network topology, Purdue model, logical zones and conduits, geographic layout, and business-oriented functional view. This multi-view approach allows CISOs, OT engineers, site managers, and network administrators to work on the same dataset in their preferred representation. Seclab Xplore monitors changes and detects threats through four complementary engines: cartography-based change detection that flags new assets or flows, customizable Sigma signature rules, Suricata network intrusion detection, and an AI behavioral engine that learns normal OT communication patterns to surface anomalies and zero-day indicators. Deployment scales from portable audit appliances for one-time assessments to fixed sensors for continuous monitoring, with full data continuity across phases. **Who Is the Company Behind Seclab Xplore?** - **Seller:** [Seclab](https://www.g2.com/sellers/seclab) - **Year Founded:** 2011 - **HQ Location:** Pérols, FR - **LinkedIn® Page:** https://linkedin.com/company/seclab/ (38 employees on LinkedIn®) ### 3. [Seclab Xport](https://www.g2.com/products/seclab-xport/reviews) Seclab Xport is a hardware device that provides electronic isolation of USB ports for OT and critical infrastructure environments. Based on patented Electronic AirGap technology, Xport physically sits between USB media and the host system, creating a complete break in the direct USB connection. The protected system sees Xport as a standard USB drive and only receives files that comply with the configured security policy. Xport blocks advanced USB-based threats including BadUSB and boot sector attacks through physical isolation rather than software detection. Security policies support direction control, file extension whitelisting, and cryptographic signature verification. When combined with sanitization stations, Xport ensures that only pre-analyzed and signed files reach the critical asset. The device requires no software installation, no driver, and no modification of the host system. It operates as plug-and-play on Windows, Linux, and macOS, including locked-down legacy systems. **Who Is the Company Behind Seclab Xport?** - **Seller:** [Seclab](https://www.g2.com/sellers/seclab) - **Year Founded:** 2011 - **HQ Location:** Pérols, FR - **LinkedIn® Page:** https://linkedin.com/company/seclab/ (38 employees on LinkedIn®) ### 4.
