Security

How we protect the words your organization writes.

In transit and at rest

All traffic is encrypted with TLS. Data on the managed service lives on a single-tenant database that Lisan operates, with secrets held encrypted in a database vault and nightly, restore-tested backups. Disk-level encryption at rest for the data volumes is on the roadmap to verify and publish here.

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.
• Single sign-on through your identity provider: on the roadmap.
