HID Global's ActivID Validation Responder is a cost effective solution for scaling a PKI Certificate validation service centered around ActivID Validation Authority. Each Validation Responder provides a local OSCP service providing real time validation without the overhead of connecting to the centralized service. Organizations deploying the ActivID Validation Responder benefit from increased security and trust by validating certificates at time of usage, without slowing down the end user experience.ActivID Validation Responder, deployed with the ActivID Validation Authority, is ideal for large organizations needing to implement real-time validation services across multiple regional networks. It is also a good fit for government agencies and partner networks participating in a federated Public Key Infrastructure (PKI) comprising multiple Certificate Authorities (CAs), in which each party requires the ability to validate the status and authenticity of external credentials.The unique distributed architecture of the solution eliminates the need for securing individual Validation Responders with their own signing keys. This greatly reduces the cost and complexity typically associated with enterprise-wide PKI deployments. Data compression optimizes network resources and bandwidth and enables the solution to scale to address user populations of millions of certificates with response times that are virtually instantaneous.
