Security

How we protect the words your organization writes.

In transit and at rest

All traffic is encrypted with TLS. Data is stored on managed infrastructure with encryption at rest, using current security protocols.

Deployment choices

• Cloud: the managed service at app.lisan.com.
• Sovereign cloud: national and government cloud environments for data-residency mandates.
• On-premises: the full engine inside your network; documents, models, and analytics never leave your perimeter.

Access

• Role-based access: writers see their own statistics; managers see team rollups.
• Admin controls for style guides, dictionaries, and team membership.
• SSO integration on institutional plans.
