An emulator on every desk
Every PC needs a client installed, versioned and configured. New hires and replaced laptops mean another ticket.
Your IBM i green screens, in any browser, in minutes.
Green Screens gives your users full 5250 access from a web browser. Nothing to install on the desktop, not one line of RPG or COBOL to change, with MFA, single sign-on and PDF printing built in.
IBM i compatible
Deploys in minutes
No code changes
Your IBM i applications still work. Getting people to them is the hard part.
The business logic on your IBM i is proven. What wears IT teams down is everything around it: the desktop clients, the VPNs, the printers and the devices that can't run an emulator at all.
Remote access that worries auditors
Opening 5250 over VPN puts the IBM i one step from every remote endpoint, often with passwords as the only control.
SCS printing headaches
Spooled output needs specific printers or add-on transform software, and label printing is its own project.
Devices left out
Chromebooks, tablets and warehouse handhelds can't run a desktop emulator, so users stay tied to a PC.
Slow onboarding
Contractors, seasonal staff and new branches wait on client installs and VPN accounts before they can do any work.
Aging web access options
Teams that relied on IBM i Access for Web need a supported way to keep browser-based 5250 running.
Introducing Green Screens for IBM i
Green Screens is a lightweight web server that sits between your users and your IBM i. It speaks 5250 to the IBM i and delivers each screen to a browser tab or the Android app, with the same function keys, fields and workflows your users already know.
No redevelopmentNo migrationNo retraining
Your applications stay exactly where they are.
Existing RPG, COBOL and CL programs run unchanged. Your IBM i stays in place, on-premises or in the cloud, and screens and keystrokes behave the way users expect.
See how it works →What changes for your team
Less to install, less to secure and less to support, while users keep the applications they rely on.
Deploy in minutes
A lightweight Java server with a short install. Point it at your IBM i and users can sign on.
No application changes
Keep your RPG, COBOL and IBM i business logic exactly as it is.
Browser-based access
Any modern browser on Windows, macOS, Linux or ChromeOS. No emulator to package or patch.
Mobile and tablet ready
Work from tablets and handhelds in the browser or with the Android app.
Stronger security
MFA, SSO and a proxy layer that keeps your IBM i off the open network.
Printing that just works
Turn SCS spool files into PDF, or send labels straight to Zebra printers.
Extend your IBM i ROI
Get more years from applications that already run your business.
Cloud or on-premises
Run it in your data centre, your cloud, or hosted and managed by Sumo Networks.
Security without compromise
Users reach a hardened web gateway, never the IBM i itself. You decide who connects, how they prove who they are, and what they can reach.
- Encrypted in transit. HTTPS/TLS from browser to gateway.
- MFA and single sign-on. Add a second factor and tie sign-on to your identity provider.
- IBM i kept off the internet. No Telnet port exposed to remote endpoints.
- Central control. Manage hosts, access rules and live sessions from one console.
- Simpler endpoints. Nothing on the PC to patch, and remote staff need no VPN just for 5250.

Desktop emulator vs. Green Screens
| Traditional desktop 5250 | Green Screens | |
|---|---|---|
| Client software | Installed and updated on every PC | Any modern browser |
| Devices | Desktops and laptops | PCs, Chromebooks, tablets, Android |
| Remote access | VPN to reach the IBM i | HTTPS gateway with MFA |
| Sign-on | Separate IBM i password | SSO and auto sign-on options |
