When Network Performance Can’t Be Left to Guesswork
Poor network or application performance can be difficult to diagnose, especially when users simply report that “the network is slow”. The real cause may be latency, packet loss, jitter, bandwidth constraints, security issues, application behaviour, device performance or a combination of several factors.
Network testing and performance tools give engineers the visibility and control they need to understand what is really happening. By recreating real-world network conditions, generating realistic traffic and analysing live or historical packet data, partners can help customers validate designs, troubleshoot faster and make better decisions before problems affect users.
Network Testing & Performance Solutions from Open Reality

WAN Emulation
WAN emulation allows engineers to recreate real-world network conditions in a controlled test environment. By introducing latency, packet loss, jitter, bandwidth limits and other impairments, teams can understand how applications, devices and services will perform before they are deployed.
These tools are ideal for testing SD-WAN, cloud applications, 5G, satellite networks, remote sites and distributed environments. They help partners demonstrate performance, identify weaknesses and give customers greater confidence before a solution goes live.

Network Delay Simulators
Network delay simulators help engineers test how applications and systems behave when network conditions are less than perfect. By adding controlled delay, packet loss and other impairments, they make it possible to replicate real-world performance issues without disrupting production networks.
They are particularly useful for software testing, device validation, application optimisation and environments where latency-sensitive services need to be proven before deployment.

Traffic Generation
Traffic generation tools create realistic network traffic so engineers can test the performance, capacity and resilience of devices, applications and infrastructure. They can be used to emulate users, clients, servers and application flows across a wide range of scenarios.
This makes it easier to test firewalls, SD-WAN gateways, load balancers, routers, switches and security devices under controlled but realistic conditions. Partners can help customers validate throughput, latency, packet loss, QoS policies and application behaviour before deployment.

Network Troubleshooting
Network troubleshooting tools give engineers deeper visibility into traffic behaviour, performance issues and packet-level detail. They help identify bottlenecks, errors, retransmissions, application delays, overloaded links and other problems that are difficult to diagnose with basic monitoring tools.
Portable and rack-mounted troubleshooting appliances are especially useful for pre-sales testing, live investigations, data centre analysis, wireless troubleshooting and post-incident review. They allow partners to move beyond guesswork and provide evidence-based answers.

Satellite Testing
Satellite testing tools allow organisations to understand how applications, devices and services will perform across high-latency, bandwidth-constrained or variable satellite links. By recreating satellite network conditions in the lab, engineers can test performance before deployment.
These solutions are valuable for defence, maritime, aviation, remote sites, emergency response and any environment where satellite connectivity plays a critical role. They help reduce deployment risk and improve application readiness.

Network Security Testing
Network security testing tools help organisations validate how security devices and network infrastructure perform under realistic conditions. By generating controlled traffic and recreating demanding scenarios, engineers can test firewalls, intrusion prevention systems, secure gateways and other critical systems.
This helps customers understand capacity, policy performance, resilience and potential weak points before services are placed under real operational pressure.
Problems We Solve
From slow applications to difficult-to-reproduce faults, Open Reality helps partners solve the network and performance challenges that affect user experience, service reliability and customer confidence.
Applications Are Slow but Nobody Knows Why
Identify whether performance issues are caused by the network, application, device, security layer or wider infrastructure.
Customers Need to Prove Performance Before Deployment
Test applications, devices and services under realistic network conditions before they are rolled out to users.
Networks Need Testing Before a Major Change
Validate upgrades, migrations, SD-WAN rollouts, cloud adoption and infrastructure changes before they impact live operations.
Satellite Links Are Difficult to Predict
Recreate high-latency and bandwidth-constrained satellite conditions to understand how applications will perform in the field.
Security Devices Need Stress Testing
Assess how firewalls, gateways and other security appliances behave under realistic traffic loads and demanding conditions.
Intermittent Issues Are Hard to Capture
Use advanced packet analysis and retrospective troubleshooting to investigate problems that are difficult to reproduce.
Application Performance Varies by Location
Test how services perform across remote sites, branch offices, cloud environments, 5G links and distributed networks.
Customers Need Evidence, Not Guesswork
Give partners the tools to provide measurable data, packet captures and performance results instead of relying on assumptions.
Cloud and SaaS Performance Is Inconsistent
Test how cloud applications, SaaS platforms and hosted services behave across different network conditions, locations and access methods.
New Services Need Validation
Prove that applications, devices or network designs are ready before they are deployed into production environments.
Network Teams Need Faster Root Cause Analysis
Reduce troubleshooting time by giving engineers clear visibility into traffic behaviour, bottlenecks and performance issues.
Teams Need to Replicate Customer Issues in the Lab
Recreate real-world network impairments in a controlled environment so engineers can diagnose faults, test fixes and validate solutions before making changes live.
The Support You Need to Win Deals
Network testing and performance opportunities often involve complex customer requirements, technical objections and environments where the problem is not immediately obvious. Partners need to understand the use case, identify the right toolset and explain the value clearly to both technical and commercial stakeholders.
Open Reality helps partners shape stronger opportunities from the start. From product selection and demo kit to pre-sales guidance, technical conversations and vendor support, we help you build credible proposals, prove the value of testing and give customers confidence in the recommended solution.
