Security at Lisan
Built for customers whose security teams ask hard questions.
Lisan serves governments and regulated enterprises, and the security model reflects that reality across every product.
Deployment options are the security model
The strongest control we offer is architectural: you decide where data lives. Managed cloud for speed, self-hosted servers for control, on-premises deployments for sovereignty, and local-only modes where products support them. Data that never leaves your network never needs a promise from us.
Platform practices
- Encryption in transit for all services.
- Workspace isolation and role-based permissions in every product.
- Scoped, revocable API keys with usage logging where APIs exist.
- Code-signed desktop installers, served and updated exclusively from Lisan's own release infrastructure at updates.lisan.org.
- Private-by-default sharing: nothing is public unless you make it so, and share links can carry expiry.
Responsible disclosure
If you believe you have found a vulnerability in any Lisan product, email support@lisan.com with details. We take reports seriously and respond quickly.
