Federal Contracting Acronym
ZT
Zero Trust
Plain-English definition
Zero Trust is a cybersecurity model that assumes no implicit trust and continuously validates users, devices, and workloads before granting access. In federal practice, Zero Trust connects to how contracting officers, program offices, and industry teams interpret requirements, document decisions, and execute awards. Authoritative context is typically found in CISA materials and agency supplements where applicable. Contractors should trace how ZT appears in the specific solicitation or contract rather than assuming uniform usage across agencies.
Why it matters
Understanding Zero Trust (ZT) reduces misalignment during proposal preparation, contract performance, and compliance reviews tied to cybersecurity obligations.
Where you will see it
SAM.gov notices, contract clauses and attachments, DoD forms and supply systems when applicable, and internal capture or program management documentation.
Example in context
During a bid review, the capture lead notes ZT in the solicitation, assigns a subject-matter owner to confirm requirements, and records the decision in the compliance matrix.
