Abstract: Systems, methods, and computer-readable media for providing network assurance across a network. In some embodiments, network traffic data of a cluster of nodes in a network environment can be gathered based on first network traffic flowing through the nodes using a first group of sensors implemented in the network environment. Network events occurring in the network environment can be identified, e.g. using sensors deployed in an infrastructure of the network environment. Subsequently, the network events can be correlated with the network traffic data to generate correlated network data for the network environment. The correlated network data for the network environment can be used to provide assurance between at least one server in the cluster of nodes and the network infrastructure of the network environment as part of providing assurance across the network environment.

Abstract: Systems and methods provide for enriching flow data to analyze network security, availability, and compliance. A network analytics system can capture flow data and metadata from network elements. The network analytics system can enrich the flow data by in-line association of the flow data and metadata. The network analytics system can generate multiple planes with each plane representing a dimension of enriched flow data. The network analytics system can generate nodes for the planes with each node representing a unique value or set of values for the dimensions represented by planes. The network analytics system can generate edges for the nodes of the planes with each edge representing a flow between endpoints corresponding to the nodes. The network analytics system can update the planes in response to an interaction with the planes or in response to a query.

Abstract: Disclosed herein are methods, systems, and non-transitory computer-readable storage media for scoring network segmentation policies in order to determine their effectiveness before, during and after enforcement. In one aspect, a method includes identifying one or more applications within an enterprise network; identifying at least one network security policy in association with the one or more applications within the enterprise network; determining a score of the network security policy based on information corresponding to exposure of each of the one or more applications within the enterprise network; and executing the network security policy based on the score
