Skylight delivers high-performance network and user experience monitoring – any application, any cloud, any network


What is Skylight?

Skylight is a virtualized performance assurance platform, delivering end-to-end network, application and service performance visibility—right from the user edge to the core network and cloud.

Skylight proactively ensures networks and cloud applications meet increasingly stringent performance requirements, optimize network capacity and meet demanding customer expectations on quality of experience.

Skylight leverages its high-quality performance data, analytics and machine learning to identify, predict and prevent customer-impacting issues.

Skylight Platform


Skylight Sensors

Collect granular and precise network, application and service data with Skylight sensors.

Skylight sensors come in a variety of forms, both software & hardware. This allows you to place Skylight sensor capabilities anywhere in the network from remote locations to the cloud, and everywhere in between.

Choose the right Skylight sensors for your requirements and deployment needs.

SoftwareL2-L7 passive traffic analysis
Skylight cloud and on-prem sensors provide lightweight passive analysis of network traffic from Layer 2 to Layer 7 on physical, virtualized, and cloud infrastructure for complete visibility and maximum control over end user experience.
SoftwareL2-L7 high-definition active testing
Skylight sensor agents can generate thousands of performance management sessions in order to actively monitor network performance and end user application experience.
Software & hardwareL2-L4 high-definition active testing
Skylight sensor control is a virtualized software test platform that can combine with Skylight hardware modules and SFPs to collect performance data from Layer 2 to Layer 4 across multi-vendor networks.
HardwareL2-L4 testing & demarcation
Skylight elements are compact network interface devices (NIDs) that enable full performance and visibility of the network along with controlling that traffic by providing service creation & demarcation, micro-second shaping and full traffic management.
