PKI to Prove Identity Public Key Infrastructure (or PKI) is largely about managing secure digital communication, to find a way to know who is who when sharing information. Otherwise, how can you be certain of the identities of obscure parties? You also need to decide and grant different individuals access and rights within, and occasionally outside, your organization. And you need to keep track of every single level of trust amongst your co-workers and business associates. PrimeKey’s extendable PKI covers all demands for authentication efficiently and reliably. Today and tomorrow. And now it’s also available in the cloud.
