Radiant Logic signs Badge deal for cross-domain access

Radiant Logic has signed an OEM agreement with Badge, embedding Badge authentication technology into the RadiantOne platform.

The deal targets organisations that need secure access across separate identity domains, including Active Directory forests, cloud identity systems and AI agents.

The combined product is now available as part of RadiantOne in software-as-a-service and on-premises deployments. It is intended for businesses and public sector bodies that need to manage access across systems that are not federated.

This challenge often arises in mergers and acquisitions, healthcare consolidations and government modernisation projects, where multiple identity environments may need to operate alongside each other for extended periods. In those cases, IT teams often need to grant access across domains without rebuilding directory infrastructure or creating formal trust relationships between systems.

Cross-domain access

Under the agreement, Badge's zero-knowledge authentication is built directly into the RadiantOne platform. The companies say this will let customers unify authentication and authorisation across unfederated Active Directory environments, Kerberos realms and identity platforms including Entra ID, CyberArk, Okta and Ping.

The setup avoids the need for forest trusts or manual federation. It uses X.509 certificates for access across separate domains, allowing organisations to connect identity providers incrementally rather than replace existing infrastructure in one step.

RadiantOne already aggregates identity data from directories, cloud platforms, databases and AI systems into a single view. Badge adds authentication that does not rely on stored secrets, passwords or device-bound credentials.

The agreement also covers AI agents, an area where companies are trying to track which software agents exist in their environment, what permissions they have and how they authenticate. According to Radiant, the integrated product can bind cryptographic identities to agents and apply runtime controls to limit what they can do.

AI governance

The focus on AI reflects a broader shift in identity management as companies seek to govern not only employees and contractors, but also machine identities and autonomous software agents. Security teams are under pressure to improve visibility over those non-human identities as their numbers rise across enterprise systems.

Radiant positions the offering as a single control layer for human, machine and agent identities. Its observability tools, it says, provide real-time visibility into identities and risks across the wider identity and access management estate.

Badge specialises in privacy-preserving authentication. According to the company, its technology derives private keys on demand using biometrics and other factors rather than storing user secrets or personally identifiable information.

Dr. John Pritchard, Chief Executive Officer of Radiant Logic, said the partnership is designed to address both commercial and operational challenges.

"Our customers face a fundamental challenge: they need to unify identity across unfederated domains without rearchitecting their directories and now extending that same level of zero trust verification and governance to AI agents," said Dr. John Pritchard, Chief Executive Officer, Radiant Logic. "By embedding Badge's zero-knowledge authentication into RadiantOne, we give enterprises a single platform that solves cross-domain trust for both humans and agents - while accelerating M&A timelines and reducing identity risk."

Badge described the deal as a way to bring its authentication method into more complex customer environments.

"Badge was built to eliminate secrets and make strong authentication universal," said Dr. Tina Srivastava, Co-Founder, Badge. "Embedding Badge inside RadiantOne means our technology is now available within the world's most complex identity environments, enabling zero-knowledge MFA and cross-domain trust at enterprise scale."

Radiant says it is used by one-third of the Fortune 100 and by 60% of US Federal Cabinet Agencies. Badge says its customers and partners include large companies in healthcare, banking, retail and services.

The partnership gives Radiant a tighter link between identity data management and authentication at a time when security buyers are looking for ways to reduce fragmentation across identity stacks. It also gives Badge a route into larger installed environments where cross-domain identity problems are often hardest to solve.

The integrated product is available immediately as part of the RadiantOne platform.
