The new and enhanced features in this release are as follows:

vRealize Network Insight supports any device that sends NetFlow data. Netflow versions 5, 7, 9 and IPFIX are supported. The flows involving the physical entities are enriched with the information about the DNS domains, DNS Host names, Subnets, and Layer2 Networks. This feature is available only for the Enterprise License users only.
- Flow Analytics Dashboard (Enterprise Edition)
The newly added flow analytics dashboard analyzes network flow data and provides deeper insights into network behavior by reporting on top talkers, new services that are accessed, and outliers. These insights can significantly aid network troubleshooting, capacity planning and security auditing activities, while also provide accounting reports to other parts of the organization. This feature is available for the Enterprise License users only.
- AWS Enhancement (Enterprise Edition)
The Virtual Private Cloud (VPC) dashboard is enhanced to show a topology of the security posture of the VPC and make security group troubleshooting easier. Security groups and firewall rules are analyzed to identify who can talk to whom as well as misconfigurations. In addition, vRealize Network Insight now also supports AWS GovCloud. This feature is available for the Enterprise License users only.
- Integration with NSX-T 2.0
vRealize Network Insight integrates with the NSX-T deployments in which the VMs are managed by vCenter to provide visibility into the NSGroups and the Firewall Rules.
- Public API
The first version of Public API for vRealize Network Insight is available from this release. The REST APIs offer services for Authentication, Data Source Management, Entities, Applications, Micro Segmentation, and Search. The API specifications are accessible from the product UI under Profile. Currently, the API access is for the On-Premises version of software only.
