Our offering for CBRS


CBRS Managed PKI Service

The CBRS Managed PKI Service is a turn-key solution for companies who need CBRS certificates with a minimum investment. In the service, end-entity certificates are issued by an INSTA hosted Sub CA (CBSD, SAS, etc.) based on Customer’s requests.

CBRS Root CA Service

The CBRS Root CA Service is suitable for companies who want to run their own CBRS Sub CA. INSTA provides the Root of Trust for the Sub CA by issuing the Sub CA certificate, enabling the Customer to issue end-entity certificates fully trusted in the CBRS ecosystem.
