Sigma sits atop your existing cloud database and uses a secure connection to query your data warehouse directly. Sigma writes a query to access the data needed to answer your question and returns the result in the browser.
Sigma provides a single point of access for your data, so you can establish robust data governance, keep report sprawl to a minimum, and restrict access to sensitive information. Administrators can set permissions by team and namespace, and restrict data access directly from the database as well.
We built Sigma with security in mind, which is why we included features like immutable hosts, container checking, and threat detection. At Sigma, we make every effort to provide secure data analytics and ensure our platform is protected at every layer of the stack.
