Who is ThousandEyes?
ThousandEyes is a network intelligence and digital experience monitoring platform used to observe, test, and analyze application and service delivery across the internet, cloud, and enterprise environments.
- Internet and cloud-centric digital experience monitoring for applications, networks, and services (observability).
- Active and passive network monitoring from cloud, enterprise, and end-user vantage points (network performance monitoring).
- Visualization of internet, Wide Area Network (WAN), and multi-cloud paths to identify performance degradation and availability issues (network path analytics).
- Monitoring of Software-as-a-Service (SaaS), web, and internal applications to assess availability, performance, and user experience (application performance and experience monitoring).
- Integration with Cisco networking and security platforms for correlated insights across on-premises (on-prem), Software-Defined Wide Area Network (SD-WAN), and cloud environments (integrated network and cloud observability).

More About ThousandEyes
ThousandEyes provides cloud-based network and digital experience monitoring capabilities that enterprise, service provider, and public sector organizations use to gain visibility into the delivery of applications and services over the internet, across hybrid and multi-cloud architectures, and within internal networks. Its platform combines active probing, synthetic transaction monitoring, and endpoint data to build a correlated view of performance across the end-to-end service path, from user devices through corporate networks, service providers, and cloud infrastructures to application backends.
The ThousandEyes platform (observability) focuses on monitoring HTTP/S, Domain Name System (DNS), voice, and network-layer connectivity using techniques such as synthetic tests, path visualization based on routing and traceroute-like telemetry, and Border Gateway Protocol (BGP) route monitoring. Enterprises deploy ThousandEyes vantage points in multiple locations: cloud agents hosted in public cloud regions, enterprise agents installed in data centers or branches, and endpoint agents on employee devices. This architecture is intended to reflect actual user paths and dependencies across ISPs, content delivery networks, SaaS providers, and private infrastructure.
Within the broader monitoring and observability marketplace, ThousandEyes aligns with categories such as network performance monitoring and diagnostics, internet performance monitoring, and digital experience monitoring. The platform provides capabilities to correlate application reachability and page load metrics with underlying network conditions such as latency, loss, jitter, routing changes, or provider outages. This can help IT operations, Site Reliability Engineering (SRE), and network engineering teams distinguish between issues originating in enterprise infrastructure, third-party networks, or SaaS and cloud providers.
ThousandEyes integrates with Cisco networking and security offerings (integrated network and cloud observability), reflecting its role inside the Cisco portfolio after its acquisition. Integrations commonly involve Cisco SD-WAN, campus and data center networking, and secure access solutions, enabling embedding of ThousandEyes vantage points into routers or appliances. This model places monitoring close to traffic flows, supporting use cases such as branch-to-SaaS visibility, SD-WAN path validation, and verification of cloud on-ramp connectivity.
Enterprises typically use ThousandEyes to monitor SaaS applications, public-facing web properties, APIs, Virtual Private Network (VPN) and remote access services, and internal line-of-business applications exposed over hybrid networks. The platform’s visualization of network paths, service dependencies, and routing behavior supports incident triage, Service Level Agreement (SLA) validation with service providers, and planning for network or application migrations to the cloud. In directory taxonomies, ThousandEyes fits primarily under network performance monitoring and diagnostics, digital experience monitoring, and internet and cloud observability, with connections into application performance and user experience monitoring where network behavior materially affects service delivery.
