William Data Systems (WDS) is a pioneer of specialized IBM zSeries™ z/OS® network management solutions. Established in 1993, we are an independent global company that provides innovative solutions to run mainframe networks efficiently and securely. ZEN, the WDS network management suite, offers a selection of user-friendly and cost-effective solutions to meet your unique needs. With a proven record of technical innovation, our ideas are often copied but never bettered.

To help customers overcome both business and technology challenges, WDS provides customers with licensing and pricing terms that are as flexible as our solutions. Some of our competitors like to make unsubstantiated and entirely subjective claims that their products are the best in the world. We believe the customer is better placed to decide what's best for their business so we leave the hyperbole to the competition.

WDS supports customers worldwide across all vertical markets and our client list includes Fortune 100 companies and government agencies. WDS is an Advanced IBM Business Partner and a member of the IBM PartnerWorld for Developers program. We are committed to the global z/OS networking market and to leading the way with innovative solutions through the latest advances.
