Sole Source Solicitation - Ensono - mainframe services

The State of Colorado Governor's Office of Information Technology is issuing a Sole Source Solicitation for Hosted Mainframe as a Service (MFaaS) with Ensono, LLC. This procurement establishes a Statement of Work for mainframe services with a service term of 17 months beginning upon execution of the applicable Task Order. The scope of services encompasses hosted mainframe infrastructure and support, with detailed technical specifications contained in Exhibits G, H, I, J, and K of the contract document. Key deliverables and client obligations include provision of necessary access to environments, availability of subject matter experts, participation in required workshops with a minimum of five business days' notice, provision of procedural documentation, designation of a single point of contact, and management of internal communications and change management activities. Ensono retains discretion over staffing assignments and requires background screening for all personnel requiring facility access. The services may be performed at client facilities or remotely at Ensono's discretion. The solicitation was posted on March 24, 2026, with a due date of March 27, 2026, representing a compressed three-day response window. Any services or modifications not expressly included in the Scope of Work are considered out of scope and subject to amendment at Ensono's then-current list rates, with equitable adjustment provisions available if concealed conditions, unmet client responsibilities, or client-caused delays are encountered.

This is a Sole Source Solicitation, meaning it is restricted to Ensono, LLC as the sole qualified vendor and does not permit competition from other organizations. The contract establishes that the State of Colorado remains responsible for compliance with all legal and regulatory requirements, including those outlined in IRS Publication 1075, despite Ensono providing certain security services. The document includes change control procedures whereby either party may submit written change requests; however, changes mandated by Ensono due to changes in stated assumptions or client failure to meet obligations are deemed mandatory, with client refusal potentially resulting in termination for cause and associated early termination charges. Existing incumbent vendor and infrastructure integration details, as well as specific award values or budget ranges, are not explicitly detailed in the available solicitation documentation and would be contained within the referenced exhibits and Task Order documents not provided in this summary.
