Best Operational Technology (OT) Security Software with a Free Trial of 2025

Sectrio is a comprehensive OT/IoT cybersecurity solution that identifies and secures connected infrastructure. It provides a safety net to mitigate threats and unprecedented visibility across device types and systems, enabling businesses make informed decisions about their security posture. It uses a robust detection strategy that uses signatures, heuristics and machine learning-based anomaly detectors to identify and remediate threats in converged networks. This includes IoT, OT, IoT and Cloud environments. It protects your infrastructure against sophisticated attacks like zero day, APTs and malware. Our multi-layered approach to securing a constrained ecosystem and our consulting services have helped our customers stay safe from advanced threats.

Continuous asset discovery, vulnerability management, threat detection, and continuous asset discovery for your Internet of Things and operational technology devices (OT). Ensure IoT/OT innovation by accelerating IoT/OT innovation through comprehensive security across all IoT/OT devices. Microsoft Defender for IoT is an agentless, network-layer security solution that can be quickly deployed by end-user organizations. It works with diverse industrial equipment and integrates with Microsoft Sentinel and other SOC tools. You can deploy on-premises and in Azure-connected environments. Microsoft Defender for IoT is a lightweight agent that embeds device-layer security in new IoT/OT initiatives. Passive, agentless network monitoring allows you to get a complete inventory and analysis of all your IoT/OT assets. This is done without any impact on the IoT/OT networks. Analyze a variety of industrial protocols to identify the device details, including manufacturer, type, firmware level, IP or Media Access Control address.

Protect essential systems while ensuring smooth operations. Consolidate the visibility of all assets within your integrated environment through a single dashboard. Anticipate vulnerabilities in your operational technology (OT) landscape. Eliminate high-risk threats before they can be taken advantage of. Streamline asset identification and generate visual representations of network assets for a cohesive overview, which encompasses workstations, servers, industrial controllers, and IoT devices. Employ connector engines to focus on applications that oversee IoT devices and their interconnections for a thorough inventory. Oversee your assets by monitoring their firmware and operating system versions, internal configurations, applications and user access, serial numbers, and backplane configurations for both OT and IT equipment. Utilize a sophisticated multi-detection engine to spot network irregularities, enforce security protocols, and monitor local modifications on devices associated with significant risks. This comprehensive approach not only enhances security but also provides operational insights that can drive better decision-making.

Your industrial operations are at risk from cyber threats due to the deeper integration of IT, cloud, and industrial control networks (ICS). Cisco Cyber Vision was specifically designed for OT and IT teams to collaborate to ensure production continuity and safety. Now you can deploy Industrial Internet of Things technologies and reap the benefits of industry digitization efforts. Start your OT security project with an accurate list of your industrial assets, communication patterns, and network topologies. Your SOC (security operation center) should have OT context. This will allow you to leverage the money and time you have spent on IT cybersecurity to protect your OT network. You can take OT security to the next step: Provide detailed information to comply regulations and facilitate collaboration between IT and OT experts.
