<unlocking the potential of legacy systems>

Helping enterprises reimagine what their systems can do

Our mission is to transform legacy systems into a foundation for growth and innovation. By modernizing without risky rewrites, disruption, or downtime, we enable enterprises to unlock systems integrations, agility and long-term value from the systems they already trust.

The goal is clear: to help move faster, work smarter and realize the full potential of the systems they already depend on.

TRANSFORM & DESIGN

Legacy connectivity

Seamless legacy connectivity

Terminal connected to mainframe system

Secure, high-speed access to IBM systems, zSeries (mainframes), and iSeries (AS/400) is achieved through TN3270 and TN5250. Host applications stay intact while gaining reliable, modern connections, avoiding costly rewrites or disruptions.

GUI modernization

From green screens to modern interfaces

Digital screenshots of computer interfaces and financial data floating in a 3D space, depicting Graphical User Interface windows and several mainframe screens blown away and vanishing because of the windows replacing them.

NetPhantom transforms 3270/5250 terminal sessions into intuitive desktop, web, and mobile applications. With drag-and-drop design tools and HTML5 integration, enterprises modernize user experiences without altering backend logic.

Customizable UX

Design workflows that fit your business

Host screens are automatically parsed into templates that can be customized with workflows, adaptive layouts, and localization. Teams deliver consistent, device-ready experiences that can scale up to 64K windows, while legacy logic remains untouched.

CODE & INTEGRATE

Language Choices

REXX to NetRexx to Java: Performance without compromise

NetPhantom supports REXX, the interpreted scripting language widely known in the IBM mainframe world, making development simple and accessible. It automatically converts REXX scripts into NetRexx, which compiles into native Java binary code. This workflow enables developers to deliver huge performance gains while preserving familiarity, with the added advantage of integrated private AI coding assistance for even greater productivity.

If you choose to use Java, the NetPhantom API calls and syntax is the same.

Runtime UI components

Reliable execution across environments

Applications run on lightweight runtime components built with Java Swing UI, ensuring consistent behavior across desktops, browsers, and mobile devices. This architecture simplifies deployment and upgrades, giving IT teams fast rollout and stable performance without disruption.

Integration ready-middleware

Unlock legacy data for modern systems

Existing enterprise systems connect seamlessly with Java APIs, web services, CAD applications, finance platforms or analytics tools. Legacy data becomes an active part of modern workflows instead of remaining siloed.

TEST, DEPLOY & MAINTAIN

Scalable session management

Scalability

NetPhantom supports tens of thousands of concurrent users with load balancing, real-time monitoring, and automatic session recovery. Parallel session support gives IT teams visibility and rapid troubleshooting without downtime.

Simplified maintenance & operations

Maintain with minimal effort

Streamline maintenance with hot reloads, real-time updates and zero downtime. A centralized dashboard gives full visibility into sessions, performance metrics, and user activity, making it easy to manage thousands of users. By simplifying troubleshooting and reducing operational overhead, IT teams maintain full control while keeping systems running seamlessly.

Hosting

Secure hosting on your terms

Enterprises can choose cloud or in-house hosting. For sensitive data, keeping systems isolated from the internet provides maximum privacy and protection against external threats.
