Indegy provides situational awareness and real-time security for industrial control networks to ensure operational continuity and reliability. The Indegy platform delivers comprehensive visibility and oversight into all OT activities, including changes to controller logic, configuration, and state.


The platform works across all vendor devices by utilizing control network inspection of proprietary control communications and patent-pending, agentless controller verification technology that validates PLC firmware, code, and configuration.


Preempt protects enterprises from security breaches and malicious insiders with a patented behavioral firewall that combines user and entity behavior analytics and adaptive response. This proactive approach allows organizations to mitigate threats in real time without engaging security teams.


Preempt provides visibility into enterprises' risky users, end-points, stale or compromised accounts, and privileged user behavior. By monitoring and learning the behavior of every user, group, and device on the network, including when and where they log in, their role, system privileges, and password strength, Preempt helps organizations identify malicious activity.

Its solutions are designed to make day-to-day operations visible, detect cyber attacks, and offer forensics tools for improving responsiveness. The solutions are suitable for the pharmaceutical, chemical, food and beverage, and automotive industries.


ScadaFence’s passive solution reduces operational risks such as downtime, process manipulation, and theft of sensitive proprietary information. The company offers a comprehensive product suite that includes continuous real-time monitoring of the industrial environment as well as lightweight tools designed to automate security assessment.
