Layer 4-7 Network Test Products


Unleash Your Network’s Full Potential 

Testing tomorrow’s technologies today! 

Your high-performance networks, devices, and services give you a competitive edge. Whether you’re a network equipment manufacturer (NEM) who must identify issues before shipping to prevent costly product recalls and warranty claims, a service provider validating performance under high traffic to meet service level agreements (SLAs), or an enterprise using the devices and applications, the network is your lifeline. With today’s everchanging new technologies and network architectures like edge computing, zero trust network access (ZTNA) and secure access service edge (SASE), testing is critical to verify compatibility, optimize performance and strengthen your overall security posture. By testing the performance of your network applications and services, you can quickly identify potential bottlenecks and other network issues, ensuring smooth roll-out and reliable quality of experience (QoE). Layer 4-7 testing is vital for network security, helping you to pinpoint vulnerabilities, meet compliance requirements, and improve incident response times. As cyber threats increase and become more sophisticated, it’s crucial to implement proactive security measures to safeguard your organization’s sensitive data and mitigate potential risks. As networks become more hybrid and distributed, it’s also important to validate performance, scalability and robustness. Testing determines exactly how well your network can handle growing traffic loads and adapt to changing user demands, enabling you to prevent performance degradation and maintain high availability. Keysight offers the industry’s highest-performance solutions with the most realistic application workloads, traffic mixes, dynamic payloads, and threat simulation and evasions. Our layer 4-7 test solutions replicate your network in action and support a wide range of protocols and applications, with realistic testing scenarios. Explore our solutions and stay a step ahead of the game! Layer 4-7 Network Test Software

  • Emulates fully integrated broadband network infrastructures with application traffic testing including modeling the dynamic nature of user behavior. 
  • Works smoothly in virtualized network environments and runs from a large number or commercially available compute environments including both private and public clouds to validate VNF/PNF with functional testing and performance benchmarking. 
  • Industry standard for network service testing (IPsec, TLS, multi-play with VoIP/video/data) featuring extensive perflow, per-subscriber analysis.


Industry’s first cloud native elastic application and security test solution for zero trust in distributed cloud 

  • Create digital twin of users, applications, and attacks to validate network performance, security efficacy and quantify user QoE in real-world distributed and hybrid networks. 
  • Test the functionality and performance of zero trust policies with authenticated and unauthenticated application traffic and security attacks. 
  • Validate the control plane performance and scalability of SSL VPN or IPsec Gateways, and the application performance and security efficacy of VPN enabled network security solutions. 
  • Deploy lightweight traffic agents as containerized pods (on-prem or managed Kubernetes), VMs, COTS, and private or public cloud (AWS, GCP, Azure). 
  • Test network application performance and security efficacy in both pre-deployment lab settings and safely in live production networks. 
  • Deliver fully automated orchestration and test execution for today’s continuous integration, deployment, testing (CI/CD/CT) environments. 
  • Solve real-world test challenges for cloud migration, SD-WAN optimization, SASE validation, CDN delivery, and zero trust network access (ZTNA). 

Layer 4-7 Network Test Hardware 

Keysight’s L4-7 application-focused family of load modules and standalone appliances includes APS, CloudStorm, PerfectStorm and Novus-NP, that collectively offer the industry’s most scalable solution set for testing converged multi-play services, application delivery, and network security platforms. These solutions deliver the insights you need to balance cybersecurity with application and encryption test performance, enabling you to effectively identify security gaps, performance bottlenecks, and interoperability issues.
