zero-trust privacy model
Enterprise-grade privacy protection.
Built for organizations that cannot compromise on data confidentiality. Your emails never leave your environment, and we never see your content.
GDPR compliant
Built around European data protection requirements. Customer DPAs available; sovereign deployment options on Enterprise contracts.
No content storage
Email bodies and attachments are analysed at compose-time and discarded. We never persist message contents — only the finding that triggered (e.g. "external_check warned").
No training, no logging
The AI grammar module is confidential by design: zero training on your data, no logging of email contents. Findings are recorded; bodies are not.
Encryption at rest and in transit
AES-256 at rest for all operational metadata. TLS 1.3 in transit between the Outlook add-in and the Mail Intelligence service.
Data residency control
Operational metadata (module config, finding events) pinned to EU or US today. UK and AU sovereign on Enterprise contracts.

the mail intelligence privacy promise
We process threats, not content. Your emails remain in your Microsoft 365 environment, encrypted and inaccessible to us. We identify risks without ever reading, storing, or analyzing your actual communications.
