  2. If you are deploying the instance into an Azure Virtual Network, you must ensure it can reach TCP port 8834 on an IP address associated with the instance. This is needed to complete the configuration process, as well as for the use of the product.

  3. Configure the instance and/or the Azure Virtual Network so that Nessus can communicate with Tenable servers; this is required for registration and plugin updates. If for some reason this is not possible, please refer to the Tenable.io User Guide regarding off-line updates.

  4. Generally, you will connect to the public IP address (or external hostname) associated with an instance. If you are connecting to Nessus over a VPN to an Azure Virtual Network, it may be the private IP address. The IP addresses associated with the instance can be found under the virtual machine Settings.

  5. After the instance has initialized, open a browser and connect to the instance to complete the configuration. For example: https://<IP address or hostname>:8834

  6. The following welcome screen will be displayed:


To complete the configuration, please refer to the Nessus User Guide.

Note: Prior to scanning, you must request permission to conduct vulnerability and penetration testing on instances in the Microsoft Azure cloud environment.
