Top Risks
Highest agentic risk in this batch: extension reads browser content including SaaS apps, internal tools, and sensitive web pages. Consumer opt-out training default means data used for training unless explicitly opted out. 5-year retention if training enabled. Beta status means security posture less proven.
Mitigations
Opt out of training data sharing immediately via account settings. Limit use of extension on sensitive SaaS tools and internal platforms. Review browser permissions granted to extension. Monitor Anthropic's extension-specific policy updates as it exits beta.

Highest Risk Categories
The highest-scoring risk categories identified in this assessment.
Legal Terms
Consumer terms apply, which are generally less enterprise-friendly than API/commercial terms. Dispute resolution follows consumer Anthropic ToS. Specific arbitration details less transparent than some peers. Liability caps standard.

Training Use
Claude browser extension follows consumer terms (not API terms). As of 2025, consumer default is opt-in training; users must actively opt out. Extension accesses browser content including SaaS apps, meaning richer data exposure when training opt-in is active.
5
/10
Data Retention
Consumer terms apply: if user consents to training, retention extended to 5 years. Default without training consent is shorter. Extension-processed browser data follows same consumer retention schedule. Less favorable than API terms.
