MicroSec Platforms consists of two main security solutions designed for IoT and OT environments: Protection Suite (LCMS) and Monitoring Suite (MicroIDS). The Protection Suite (LCMS) provides device and network management with lightweight PKI capabilities. It is designed to operate on constrained devices with limited memory, computing power, and bandwidth. The platform uses microcertificates that are 20x smaller than traditional certificates, requires 500x less memory, and operates with 40x more energy efficiency compared to legacy solutions. It supports protocol-agnostic deployment and interoperability across heterogeneous networks. The Monitoring Suite (MicroIDS) offers threat detection and assessment capabilities using machine learning-based anomaly detection. It provides instant remediation for zero-day attacks on devices and networks. Both platforms are designed for deployment in both greenfield and brownfield environments, targeting Industrial IoT and OT systems including microcontrollers, sensors, and devices across networks. The solutions address industries such as maritime, manufacturing, smart cities, connected buildings, and critical infrastructure. The platforms support zero trust architecture, supply chain security, embedded security, compliance management, asset discovery, and threat detection use cases.
