Platform One, the Department of War’s enterprise DevSecOps initiative, is hosting an Industry Day and seeking commercial software vendors to participate. They need partners capable of integrating into regulated, Zero Trust–aligned environments (IL2, IL4, IL5) with offerings in container security, infrastructure management, DevSecOps tooling, and workflows that support Authorization to Operate (ATO). Interested vendors must complete the attached Microsoft Form Survey to be considered; email submissions alone will not be accepted. The Platform One Team will review responses and communicate next steps after the selection process is complete. No budget or performance location is specified.
