About this opportunity
The Department of the Interior's Interior Business Center has awarded a sole-source contract to Vanguard Integrity Professionals, Inc. for Vanguard z/Assure Resource Access Control Facility licenses under contract 140D0426P0225 on July 20, 2026, on the basis that only one source is reasonably available.
The justification rests on brand-name requirements and Vanguard's unique qualifications demonstrated through proof-of-concept testing. DOI evaluated multiple commercially available code scanning products; only z/Assure combined the capability to detect vulnerabilities in the z/OS mainframe environment while producing high-level reports that non-IT professionals can understand and act upon for timely remediation. Competitive alternatives generated overly technical reports requiring expert interpretation. Market research included internet searches, NASA SEWP, and GSA IT Schedules; Vanguard confirmed it has no authorized resellers for these proprietary licenses.
The contract covers mainframe software licensing, annual support, maintenance, and updated software versioning to support DOI's Federal Personnel and Payroll System vulnerability management and cybersecurity defenses. The period of performance is a 12-month base with two optional 12-month renewal periods under a Firm-Fixed-Price structure. The requirement is set aside as a Women-Owned Small Business procurement under NAICS 513210 (Software Publishers). Vanguard is located in Las Vegas, Nevada. DOI commits to periodic reassessment of alternative solutions for future requirements. The Contracting Officer is Matthew Mosellen, with Program Manager/COR Catherine Beach concurring.
