Compliance and security

Many of the world’s largest banks, insurance companies and government agencies rely on Rocket Open Source Languages and Tools for zSystems/OS. That’s why we feel it's essential that we check our deliverables for vulnerabilities and follow proper licensing requirements.

All of our products are:

  • Continuously kept up to date against the NIST National Vulnerability Database
  • Scanned for both security vulnerabilities and conformance to proper open-source licensing prior to release

Four options for delivering open-source to your users

Rocket Open AppDev for zSystems open-source ports can be delivered and maintained for your internal users in four different ways: public conda channel; private conda channel; on-premise conda file channel; SMP/E.

Conda is uniquely suited to the mainframe world thanks to its three levels of available security, including the most secure file channel option for air-gapped mainframes.

All conda channel options support dependency and version compatibility checking, protecting you against dependency and version mismatches and allowing you to run multiple versions of packages.


All conda channel options support the creation of environments that can be activated and deactivated by a simple command enabling you to separately maintain dev, test, staging, and production systems with ease, each having different versions of open-source ports.

Secure repositories with guaranteed provenance
Whether you're using our secure channel server, your own file channels, or SMP/E, our compliance and security system will give your team confidence that you know where your open-source technology is coming from, that it's authentic and tamper-free, and that it's been scanned, vetted, and tested. All of the open-source products and packages we provide are ported, built, and audited by the team here at Rocket software.

Our Open-Source Support packages are based on the same world-class, customer-centric principles as our other support offerings. When it comes to open-source support, we're offering support and fixes for open-source development tools as opposed to consultancy or solution engineering services.
