Connector agents

Connector Agents enable secure, reliable communication between your on-premises systems and Novacura Cloud. They act as lightweight, self-managed services that allow you to seamlessly access data and services hosted behind firewalls—without exposing your internal infrastructure to the public internet.

Connect Agent data flow

Once installed within customer premise, a Connector Agent establishes outbound-only connections over secure channels to Novacura Cloud. This approach simplifies deployment—there’s no need to open inbound firewall ports or configure VPNs.

Communication Requirements

The agent supports two outbound communication protocols: AMQP over TCP and AMQP over WebSockets (HTTPS). If no protocol is explicitly configured, the agent defaults to AMQP over WebSockets.

Required Ports

Transport Type	Protocol	Port	Note
AMQP over WebSockets	HTTPS	443	Default option
AMQP over TCP	AMQP	5671	To enable AMQP over TCP, add the following entry to the appSettings.json file located in the agent’s installation directory after completing the installation. "TransportSettings": { "TransportType": "AmqpTcp"}

Regardless of whether the agent uses AMQP over TCP or AMQP over WebSockets, Port 443 must be open to allow the Connector Agent to communicate with Novacura Cloud and access any other REST endpoint.

Connectors

Depending on the configured connectors in the Hub, additional outbound access may be required.

Email connector

Protocol	Default Port	Usage
SMTP	587	TLS
SMTP	465	SSL

Database connectors

System	Default Port	Notes
SQL Server	1433	Default SQL server port
Oracle	1521	Default Oracle listener port

Make sure your firewall allows outbound access to the services and ports used by the configured connectors.
