Best Operational Technology (OT) Security Apps for Android of 2025

The Tosi Platform is an innovative Cyber-Physical Systems solution specifically crafted to safeguard, link, and manage Operational Technology (OT) networks as well as essential infrastructure. In contrast to conventional IT tools that have been modified for OT usage, Tosi is built from the ground up to cater to industrial settings, offering support for native industrial protocols and resilience against extreme temperature variations, all while eliminating the need for complex configurations. Its deployment process is exceptionally swift, with sites becoming operational in less than five minutes through a straightforward “plug-and-go” approach, which empowers organizations to securely and efficiently connect their distributed infrastructures without the necessity for specialized IT knowledge. The platform employs a robust zero-trust security framework that includes enterprise-level protections such as end-to-end 256-bit AES encryption, hardware-based authentication using RSA keys, the absence of open inbound ports, and compliance with ISO/IEC 27001:2022 standards. Additionally, Tosi provides an integrated management experience through a single interface known as TosiControl, which allows users to visualize network topology for better oversight and control, enhancing operational efficiency and security across the board. This comprehensive design not only streamlines management but also strengthens the overall security posture of industrial environments.

BlastShield represents a cutting-edge zero-trust, software-defined perimeter solution meticulously crafted to safeguard essential IT and OT assets by making them invisible and inaccessible to unauthorized entities. By creating an encrypted, peer-to-peer overlay network, it effectively conceals protected devices and sensitive data from network scanning and traffic analysis tools, which helps avert credential theft, reconnaissance efforts, and lateral movements within the network. The solution integrates phishing-resistant, passwordless multi-factor authentication methods—including mobile authenticators and FIDO2 keys—with microsegmentation, encryption of data in motion, and policy-driven access controls, thereby ensuring that only explicitly authorized devices and users are allowed to connect. Furthermore, BlastShield is versatile enough to be deployed in a variety of network environments, such as TCP/IP, SCADA, SD-WAN, or even raw Ethernet, making it capable of safeguarding a diverse range of assets from legacy OT/ICS equipment and sensors to PLCs, HMIs, cloud virtual machines, and virtual infrastructures. Its robust security framework not only enhances protection but also streamlines operational efficiency across different technological landscapes.
