Mainframe Access Without the Desktop Burden

Desktop 3270 emulators add installs, patching, and audit overhead to every device. Jubilant moves that access to the browser, centrally managed and secured, without changing your mainframe applications.

Zero client, zero installs

No applets, plugins, or installs — users open a browser and work. Any device and any browser is supported, including legacy browsers without HTML5.

Compliance built in

Compliant with the Digital Operational Resilience Act (DORA), 23 NYCRR Part 500, and the U.S. federal mandate on multi-factor authentication — so regulated access stays regulated.

Total security, penetration tested

WebSockets and the latest SSL/TLS, KPMG penetration tested. Access integrates with your wider security stack rather than sitting outside it.

Fast, data light, hosted your way

Extremely performant — surpassing even desktop emulators — and data light. Run it in the cloud (MS Azure, Oracle Cloud), your data center, or locally.

Certified and compliant for regulated environments
