01What attorney-client privilege requires
Privilege is a posture, not a label.
The privileged relationship has to survive the technology that supports it. Cardinal scopes engagements so the development partner, the deployment infrastructure, and the AI integrations all sit inside the privileged scope.
The privileged relationship has to survive the technology. That means the development partner, the deployment infrastructure, the AI model calls, and the document handling are all scoped so that privilege isn't pierced by the tools themselves. Cardinal scopes engagements so the work product, communications, and source material stay inside the privileged scope from the first commit.
PII handling is where most legal platforms accumulate risk. Personally identifiable information in case files, deposition transcripts, and discovery documents has to be isolated before it touches any system that wasn't built for it. Cardinal's Redactor tokenises PII before any AI processing happens, so the privileged content never leaves the privileged environment unredacted.
