Cathedral

Record description

Cathedral investigated multiple third-party business SaaS vendors connected to Anthropic in October 2026. Its company-reported access to employee and meeting content is wider than the subset acknowledged by Anthropic. The target of the research was not the Claude model-training or conversation environment. The Washington Post and the vendor account establish a dispute over scope and timing; neither provides full incident forensics or names each vulnerable SaaS implementation. Contested case.
