    NetBrain

    NetBrain

    NetBrain

    Founded in 2004, NetBrain brings Agentic NetOps to enterprise operations with complex hybrid-cloud networks. Pre-built AI agents grounded in a NetOps Harness, the network context engine, provide governed execution of the entire lifecycle from diagnose, change, and assess to prevent and predict. The platform turns each diagnosis into deterministic automation deployed across your network, eliminating recurring issues faster and at lower cost. Governed execution means agents' actions are grounded before they touch your network, making agentic operations safe and trustworthy. Connect and enrich your cross-domain ecosystem across ITSM, observability, and cloud platforms.

    MATLAB

    MATLAB

    The MathWorks

    MATLAB® combines a desktop environment tuned for iterative analysis and design processes with a programming language that expresses matrix and array mathematics directly. It includes the Live Editor for creating scripts that combine code, output, and formatted text in an executable notebook. MATLAB toolboxes are professionally developed, rigorously tested, and fully documented. MATLAB apps let you see how different algorithms work with your data. Iterate until you’ve got the results you want, then automatically generate a MATLAB program to reproduce or automate your work. Scale your analyses to run on clusters, GPUs, and clouds with only minor code changes. There’s no need to rewrite your code or learn big data programming and out-of-memory techniques. Automatically convert MATLAB algorithms to C/C++, HDL, and CUDA code to run on your embedded processor or FPGA/ASIC. MATLAB works with Simulink to support Model-Based Design.

    Tosi

    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.
