Elisity is a leap forward in network segmentation architecture and is leading the enterprise effort to achieve Zero Trust maturity, proactively prevent security risks, and reduce network complexity. Designed to be implemented in days, without downtime, upon implementation the platform rapidly discovers every device on an enterprise network and correlates comprehensive device insights into the Elisity IdentityGraph™. This empowers teams with the context needed to automate classification and apply dynamic security policies to any device wherever and whenever it appears on the network. These granular, identity-based microsegmentation security policies are managed in the cloud and enforced using your existing network switching infrastructure in real-time, even on ephemeral IT/IoT/OT devices. Founded in 2019, Elisity has a global employee footprint and a growing number of customers in the Fortune 500.

Moddable empowers embedded developers to tap into the vast JavaScript ecosystem to accelerate delivery of innovative IoT products. The open source Moddable SDK brings the JavaScript language that powers the web to the low-cost hardware that powers consumer and industrial IoT. Software developers are now free to use many standard tools of web development instead of wrestling with proprietary embedded SDKs. The Moddable SDK integrates support for networking, sensors, visually rich touch displays, security, audio, data storage, and more. Enterprises building with the Moddable SDK realize a faster time to market with products that are more secure and reliable. Enterprises can unlock the full potential of their hardware, minimize the need for customer support through easy to understand touch screen interface, and deliver updates faster with Moddable's modular update technology. IoT has long suffered from a lack of robust software standards. Moddable is ending that era through standardization efforts that allow manufacturers to quickly move between hardware vendors. Moddable is leading the movement to JavaScript-powered IoT products through contributions to standardizing embedded JavaScript APIs in Ecma TC39 and TC53 and development of XS, the only modern JavaScript engine for embedded.
