Phosphorus Intelligent Active Discovery (IAD) is an agentless xIoT device discovery and classification solution designed to safely identify and assess IoT, OT, IIoT, and IoMT devices across enterprise networks. Unlike legacy passive or brute-force active scanners, IAD communicates with devices using native device protocols, avoiding operational disruption to mission-critical or life-critical systems. Key characteristics of the solution include: - Evidence-based device identification providing 100% device certainty, eliminating assumption-based classification - Coverage of more than 950 xIoT device vendors and manufacturers, with a patented "Genus-Species" approach covering over 1 million device models - No dependency on network infrastructure such as SPANs or TAPs; deployable on-premises or in the cloud in minutes without agents - Customized Discovery Agendas that generate tiered probe sequences to increase discovery speed while minimizing unnecessary network traffic - Assessed to be significantly faster than traditional passive scanners and more efficient than legacy active scanners, with documented discovery times ranging from under 5 minutes for ~1,800 IPs to approximately 6 hours 40 minutes for 1.2 million IPs - Integrated into the Phosphorus Unified xIoT Security Management Platform, extending beyond discovery to remediation of passwords, firmware, certificates, and insecure configurations - Net-new device coverage can be added within hours regardless of vendor or device type
