What are Operational Technology (OT) Security Apps for Android?
Operational Technology (OT) security software protects the critical systems and infrastructure that control industrial operations, such as manufacturing plants, power grids, and transportation systems. It provides real-time monitoring, threat detection, and risk management tools to safeguard OT environments from cyberattacks, malware, and insider threats. The software often includes features like network segmentation, anomaly detection, and incident response to ensure the integrity and availability of industrial systems. By bridging the gap between traditional IT and OT, OT security software enhances the security posture of industrial operations while minimizing downtime and ensuring safe, continuous production. Ultimately, it helps organizations secure their vital operational assets and prevent disruptions to critical infrastructure.

Tosi
Tosi
The Tosi Platform is a purpose-built Cyber-Physical Systems platform designed specifically to secure, connect, and control Operational Technology (OT) networks and critical infrastructure. Unlike traditional IT tools adapted for OT, Tosi was engineered from the ground up for industrial environments: it supports native industrial protocols, tolerates extreme temperatures, and requires no complicated configuration. Deployment is rapid, sites can be up and running in under five minutes with a “plug-and-go” setup, allowing organizations to connect distributed infrastructure quickly and securely without specialized IT expertise. It implements a zero-trust security model with enterprise-grade protections: end-to-end 256-bit AES encryption, hardware-based authentication (with RSA keys), no open inbound ports, and ISO/IEC 27001:2022 certification. With Tosi, you get unified, centralized management through a single interface (TosiControl), enabling visual network topology views.Starting Price: Free -

BlastShield
BlastWave
BlastShield is a zero-trust, software-defined perimeter solution designed to protect critical IT and OT assets by rendering them invisible and inaccessible to unauthorized users. It establishes an encrypted, peer-to-peer overlay network that cloaks protected devices and data from network scanning or traffic analysis tools, preventing credential theft, reconnaissance, and lateral movement. BlastShield combines phishing-resistant, passwordless multi-factor authentication (including mobile authenticators or FIDO2 keys), microsegmentation, data-in-motion encryption, and policy-based access controls to ensure only explicitly authorized devices and users can connect. It supports deployment across a wide range of network environments, TCP/IP, SCADA, SD-WAN, or even raw Ethernet, and can protect everything from legacy OT/ICS equipment, sensors, PLCs, HMIs, cloud VMs, and virtual infrastructure.Starting Price: Free -
