Protect your agency’s staff, buildings, and property with Special Item Number SIN 541519CSP Credential Service Providers.
Per NIST, credential service providers are “trusted entities that issue or register subscriber authenticators and issue electronic credentials to subscribers.” CSPs, as part of the identity proofing process, collect evidence to reliably identify an applicant, or citizen. Once an applicant’s identity has been established, the CSP issues a credential. The federal government has adopted the Kantara Initiative definition of two types of CSPs that can be purchased:
Eligible users: Federal, state, local, and tribal agencies
Vendor list: eLibrary
Eligible agencies can order on Multiple Award Schedule by issuing requests to vendors through eBuy and GSA Advantage.
State, local, territorial, and tribal governments may be able to purchase through Cooperative Purchasing and Disaster Purchasing programs.
You can combine SINs to meet your requirements, and may have the option to set-aside the requirement for one or more socio-economic categories.
Blanket Purchase Agreements are a great option for recurring needs and can help your agency meet strategic sourcing, compliance requirements, and socio-economic goals.
