KeyScaler by Device Authority is a cloud-based identity and access management (IAM) platform designed for Enterprise IoT ecosystems. It automates the Device Identity Lifecycle, providing automated security at scale for connected environments. KeyScaler utilizes patented technology, including Dynamic Device Key Generation (DDKG), to authenticate both brownfield devices with inadequate security and secure-by-design devices using credentials from the manufacturing process. The platform simplifies IoT deployments, reduces attack surfaces, and supports legacy devices without hardware trust anchors. KeyScaler integrates with existing enterprise security infrastructure, including PKI platforms, Hardware Security Modules, and cloud applications, offering pre-built integrations with various security systems. It provides automated Public Key Infrastructure (PKI) services specifically for IoT devices, simplifying device attestation and authorization, issuing x.509 Certificates, eliminating weak credentials, and enforcing Zero Trust policies throughout the device identity lifecycle without human intervention. KeyScaler Edge extends the platform's capabilities to Edge gateways or devices operating offline or with sporadic internet connectivity, supporting air-gapped systems and industrial environments compatible with the Purdue Manufacturing Model.
