NetBrain 12.3 introduces AI Deep Diagnosis — a major step forward in how network teams troubleshoot and resolve issues.

Instead of jumping between tools and piecing together clues, Deep Diagnosis acts as an agentic AI investigation engine that works directly on the live digital twin to identify root cause fast — with evidence to back it up.

Why It Matters in 12.3

This release is all about moving from reactive troubleshooting to AI-assisted operations that still keep engineers in control.

With Deep Diagnosis, teams can:

  • Pinpoint root cause faster with step-by-step reasoning and visual mapping

  • Cut troubleshooting time from hours to minutes

  • Guide junior engineers through expert-level workflows

  • Turn investigations into reusable runbooks for consistent resolution

  • Stay in control with human-in-the-loop validation and approval

In real-world environments, Deep Diagnosis identifies root cause in 90%+ of network issues, helping teams accelerate the entire resolution cycle.

Built for Real Network Environments

AI Deep Diagnosis in 12.3 isn’t just another AI layer — it’s built to work the way network teams actually operate:

  • Uses live network data from the digital twin — not assumptions

  • Provides transparent reasoning and evidence you can validate

  • Operates within governed boundaries — no unsupervised remediation

  • Integrates into existing workflows and tickets for faster response

Think of it as a digital operations engineer that handles the heavy investigation — while you make the final call.

From Issue to Resolution

Whether it starts from a ticket, alert, or a simple question, Deep Diagnosis:

  1. Investigates across devices, paths, and dependencies

  2. Identifies root cause with clear, evidence-backed findings

  3. Maps the issue visually for faster understanding

  4. Recommends next steps

  5. Converts the workflow into a reusable runbook

Less guesswork. More clarity. Faster outcomes.
