Network Visibility For Hybrid Networks

The need for always-on networks is pervasive, and expectations are high when it comes to keeping them connected and secure. As technologies advance, edge computing, cloud environments, sophisticated security threats, bandwidth requirements, and compliance regulations make it challenging to extract actionable insight from your network.

Keysight can help. Customers rely on our network visibility solutions to deliver rich data about network traffic, applications, and users across any networking environment. These deep insights are what we call dynamic network intelligence. It helps you continuously innovate, meet aggressive service level agreements, and keep applications running smoothly and securely.

What Is Network Visibility?

Network visibility is monitoring all the traffic and data flowing across a network at any given time. Traditional network monitoring tools — such as security and network performance monitoring solutions — rely on data packets to perform their intended function. However, you can't secure what you can't see — and modern, distributed network topologies are rife with blind spots. Network visibility tools deploy across on-premise data centers, cloud-based hypervisors, and software-as-a-service applications to capture, aggregate, and filter network packets before sending them to downstream monitoring tools.

Network Visibility: Frequently Asked Questions

Network visibility is crucial because it enables network operations teams to ensure that their monitoring tools always have a clear view of all network activity. Without network visibility tools capturing, aggregating, and filtering packets across physical and virtual network infrastructure, blind spots can hamper monitoring tools' effectiveness. Moreover, without the advanced filtering features of a network packet broker, tools can actually receive too much data — jeopardizing their efficiency and lifespan.

Network visibility tools can be separated into two categories: network packet capture and inline network infrastructure. Network packet capture tools include network taps, SPAN ports, and cloud visibility solutions. Inline network infrastructure appliances include bypass switches and network packet brokers.

Network visibility is a crucial aspect of network security. Many network security tools rely on network packets to monitor for potential breaches or identify indicators of compromise. However, your tools cannot secure what they cannot see — and blind spots can offer hiding places for cybercriminals. Modern distributed, hybrid networks require end-to-end visibility, spanning both physical data centers and virtualized network infrastructure.
