The opportunity for questions for Phase II remains closed.  The due date for Phase II proposals is extended from January 18, 2023, at 10 am Eastern to Wednesday, January 25, 2023, at 10 am Eastern. As a reminder, offerors who have not submitted a proposal under Phase I for FirstSource III cannot submit a proposal for consideration for Phase II. Offerors are reminded that once proposals are due and as the government enters source selection, individual communications with offerors may be limited.  Periodic updates will continue to be posted to SAM.gov to inform offerors of the procurement’s status. This amendment makes minor changes to the converged infrastructure devices in Attachment 8, ITVAR Salient Characteristics. The changes are noted within the tracked changes copy of Attachment 8, which has also been provided. Read more here. Related Item Update: DHS FirstSource III Solicitation - G2Xchange FedCiv
