High-performance data access that doesn’t compromise security.
Our Multi-Tier drivers give your AI agents, analytics tools, applications, and services fast ODBC and JDBC connectivity to PostgreSQL, with security enforced by attribute-based access control (ABAC). Data access policies built from user, network, operating system, application, and custom attributes are hard-wired to the database session, ensuring every connection carries the rules that govern it.
Fast for the tools. Policy-bound for your security team.

Enterprise (Multi-Tier) edition. First the server components, the Request Broker and the database agent, which run where they can reach your database: choose their operating system, its version, your database version and a driver version.
Then the client components, which run where your applications do and can use another operating system: choose ODBC or JDBC, an operating system and its version.

Applications written once to ODBC, JDBC, or ADO.NET (via its ODBC Bridge) run unchanged against PostgreSQL and other systems — the same drivers, the same ABAC-enforced security model (for the Multi-Tier edition), whether the data access client is a spreadsheet, an analytics dashboard, or an AI agent.
