Unmatched Protection for the Connected World: AIoT Defender
Nothreat™ AIoT Defender revolutionizes endpoint security by deploying an edge-AI firewall embedded directly inside lightweight CPU devices. As an ultra-light, ultra-secure, software-based firewall for IIoT edge devices, it provides real-time, adaptive protection at the device level. This solution effectively secures your large-scale IoT environments while dramatically reducing infrastructure complexity because it detects and mitigates threats utilizing continuous learning AI, thereby not requiring additional hardware firewalls.
At its core, AIoT Defender utilizes continuous learning AI to dynamically adapt to emerging threats. This proprietary system is engineered to solve the plasticity–stability dilemma in machine learning. As demonstrated by real-time learning on honeypot data, the Defender adapts dynamically, starting with zero parameters and autonomously creating new neurons and synapses. This continuous learning enables it to rapidly achieve high accuracy in threat prevention.
This dynamic learning capability allows AIoT Defender to achieve up to 97.3% accuracy in detecting and preventing cyberattacks, including zero-day threats, within just 12 minutes. It protects previously unprotected devices and zero-day vulnerable systems. The Defender is connected to Nothreat™’s Continuous Threat Exposure Management (CTEM) patterns database, providing unparalleled, automated endpoint protection.
AIoT Defender is an OEM-ready solution that ensures proactive defense right at the device level, offering a fully autonomous defense without requiring human input. By embedding protection at the edge, it eliminates reliance on external cloud processing and reduces cybersecurity costs, positioning it as a strategic investment for both resilience and operational efficiency.
