This update builds on NetBrain’s momentum from a transformative 2025, including multiple AI-enhanced platform releases and its acquisition by Blackstone. Now, heading into 2026, NetBrain AI agents integrate human-like intelligence with automation, enabling proactive network diagnosis without constant human oversight. These agents don’t just flag problems—they investigate root causes, correlate data across devices, and suggest fixes, making them a game-changer for IT pros managing sprawling infrastructures.
Inside NetBrain 12.3: AI Agents in Action
The core innovation in NetBrain 12.3 revolves around autonomous AI agents that mimic expert troubleshooting workflows. Unlike traditional monitoring tools, these agents use natural language processing and machine learning to query network data in real-time.
- Issue Investigation: Agents automatically scan configurations, logs, and performance metrics to pinpoint anomalies, such as misconfigured routers or bandwidth bottlenecks.
- Root Cause Analysis: By correlating events across multi-vendor environments, they reduce mean time to resolution (MTTR) by up to 70%, based on NetBrain’s internal benchmarks.
- Predictive Insights: Leveraging historical data, agents forecast potential failures, alerting teams before disruptions occur.
This release enhances NetBrain’s existing platform, which already supports over 2,500 enterprises worldwide. For context, similar AI-driven tools are gaining traction; check out how NetBox Labs’ AI copilot targets network engineers specifically.
Benefits for Network Diagnosis and Beyond
NetBrain AI agents deliver tangible gains for overstretched IT teams. In a landscape where networks span on-premises, cloud, and edge environments, automation isn’t optional—it’s essential. These agents handle repetitive tasks, freeing engineers for strategic work.
Key advantages include:
- Scalability: Supports networks with thousands of devices, integrating seamlessly with tools like Cisco’s ecosystem—explore Cisco’s AI networking advancements for complementary insights.
- Accuracy Boost: Reduces human error in diagnosis by 50%, drawing from a vast knowledge base of network behaviors.
- Integration with Security: Pairs well with SASE platforms for holistic operations; see Versa’s AI-powered SASE upgrades.
