# CloudQuant Data Liberator security and access

CloudQuant Data Liberator provides enterprise-grade security for data access and distribution.

## Authentication

Access to CloudQuant Data Liberator requires valid credentials provided by CloudQuant. Authentication is handled through:

* **API Keys** — Used for programmatic access via client libraries
* **User Credentials** — Used for interactive access via Excel and CQAI

## Dataset entitlements

Access to specific datasets is controlled through entitlements:

* Each user or organization is granted access to specific datasets
* Use `liberator.datasets()` (Python) or equivalent to see your available datasets
* Organization administrators can manage users and entitlements from the admin portal — see [Administration Overview](/administration/overview)
* Contact CloudQuant support to request access to additional datasets

## Network security

CloudQuant Data Liberator supports secure connectivity through:

* **TLS/SSL encryption** for all data in transit
* **IP whitelisting** for restricted access environments
* **VPN connectivity** for on-premises deployments

## Anti-virus considerations

When running CloudQuant Data Liberator client libraries locally, ensure your anti-virus software does not block:

* CloudQuant Data Liberator client executables
* Network connections to CloudQuant data endpoints
* Local cache directories used by the client

See the [Network Configuration](/network-configuration) page for detailed setup instructions.
