Stop guessing. Start mapping. 🗺️
With runZero 4.9, we’re helping defenders "map the unmappable."
Traditional tools often see a single gateway IP & stop there. runZero dives deeper, revealing the entire field-level topology of PLCs and nested devices.
But this is only half the battle. Our new attack path mapping shows you exactly how an attacker could move through your network to reach those assets, exposing the segmentation gaps you didn't know existed.

🛑 Stop assuming segmentation and start verifying it with runZero 4.9! ✅
In OT environments, a single incidental network bridge or firewall misconfiguration can lead to a costly operational shutdown.
By delivering high-fidelity asset, network, and security intelligence at scale, runZero is empowering defenders to move from assumption-based security to validated infrastructure insights across their entire attack surface.
