The Truth is on the Wire

Modern applications thrive on external integrations—APIs, third-party services, and cloud platforms—all working together to power seamless digital experiences. However, when something goes wrong, finding the root cause can be frustrating and time-consuming. The truth behind these issues often lies “on the wire,” within the raw data exchanged between your application and its external dependencies.

While traditional tools help monitor application performance or network health, they often miss the intricate details of what’s happening at this critical intersection. Qpoint was built to change that. By offering deep, actionable insights at the “wire” level, it provides a source of truth that teams can use to uncover the real story behind failures and anomalies that is often obscured by layers of abstraction and tooling.

Why Visibility into Wire Data Matters

For platform engineers and developers, external integrations and micro-services introduce layers of complexity that can cloud visibility into what’s happening during production incidents. Common questions often go unanswered:

• Did we change something?

• Is a malformed request causing a downstream issue?

• Did an integration send unexpected data back to the app?

• Are there new or unfamiliar endpoints that our app is suddenly communicating with?

• Is the issue on our side or the vendor’s?

These are the kinds of questions that traditional application performance monitoring (APM) tools struggle to answer. Logs and traces are useful but can’t provide the full picture of what's happening at the wire level—where the actual data flows occur. This gap slows debugging and keeps teams stuck in firefighting mode.

Shedding Light on Hidden Third-Party Interactions

Qpoint operates at the point where applications meet their dependencies, providing unmatched visibility into outbound traffic flows. With its eBPF-powered observability capabilities, Qpoint enables teams to:

• Debug Faster: Dive into request-level data to pinpoint issues like incorrect API keys or malformed payloads.

• Improve Root Cause Analysis: Quickly determine whether an issue is internal or external by inspecting traffic patterns and responses.

• Expose Unintended Data Flows: Identify sensitive data or misconfigured connections that may pose security or operational risks.

• Optimize Troubleshooting: Gain insights into which external systems your app is interacting with, how they respond, and where anomalies are occurring.

These capabilities mean that teams can not only resolve incidents faster but also prevent recurring issues from turning into systemic problems​​​.

How Qpoint Achieves Unmatched Visibility

At the core of Qpoint’s capability is eBPF, a transformative Linux kernel technology that allows the platform to tap directly into your application’s traffic flows:

• Full Payload Insights: Qpoint captures traffic before encryption, offering visibility into both the content and context of requests without interfering with TLS.

• Low Overhead, High Performance: eBPF enables detailed monitoring with negligible impact on system performance, making it suitable even for high-traffic environments.

• No Code Changes Required: Qpoint deploys in minutes without requiring changes to your applications or infrastructure.

By operating below the app layer, Qpoint delivers a raw and unfiltered view of what’s happening across your system’s external connections, giving you the insights you need to fix issues effectively​​​.

Unlock Critical Insights to Optimize Debugging

Qpoint empowers teams to:

• Pinpoint Payload Problems: Quickly identify malformed requests or unexpected responses that may cause failures in production.

• Understand New or Unknown Connections: Gain visibility into outbound traffic to uncover previously unknown endpoints or dependencies.

• Trace Issue Sources: Determine whether problems stem from your application, the network, or the external vendor, minimizing finger-pointing during incidents.

• Strengthen Data Governance: Ensure sensitive or regulated data doesn’t leave your environment unintentionally by inspecting outbound traffic in real time.

By providing precise, actionable insights, Qpoint transforms troubleshooting into a proactive, manageable process​​​.

A New Approach to Observability

One customer described the experience of using Qpoint like this: “It’s like having a magnifying glass for your external dependencies. When we couldn’t find the problem anywhere else, Qpoint showed us exactly what was happening on the wire.”

This level of clarity changes the game for teams managing modern, highly integrated systems. When other tools fall short, Qpoint steps in, offering the visibility needed to resolve complex issues quickly and keep systems running smoothly.
