NANOFIREWALL - AI-powered self-learning firewall for IoT, edge & embedded devices

Gartner identifies preemptive cybersecurity — AI that anticipates and neutralizes threats before they materialize — as the future of defense, with advanced deception, predictive threat intelligence, and automated response as its core capabilities, and IoT and critical infrastructure as priority segments. NanoFirewall is AST's purpose-built answer to exactly that problem.

IoT, OT, and embedded devices are the fastest-growing part of the attack surface and the hardest to defend: traditional Next-Generation Firewalls can cost up to ten times more than the device they protect, and the devices themselves lack the CPU and memory to run them. NanoFirewall closes this gap with an ultra-lightweight, autonomous, continuously self-learning firewall and WAF — combining network-layer and web-application-layer protection in a single engine with a 2 MB footprint and under 1% CPU usage.

How it works — adaptive AI, not static rules:
Unlike traditional AI that degrades over time in dynamic environments, NanoFirewall's patented adaptive AI improves continuously through ongoing learning, detecting unknown and zero-day threats with over 99.9% precision before they spread. Embedded cyber-deception traps profile attacker tradecraft on the device itself, while a community-powered model shares real-time threat intelligence across every connected device — establishing collective immunity for the entire network. It operates human-lessly, with no signatures and no manual configuration.

Key differentiators:

• Unmatched accuracy — adaptive AI flags unknown threats with >99.9% precision before they become widespread.

• Self-learning by design — deception and tailored threat intelligence anticipate attacks rather than react to them.

• Collective immunity — community-shared intelligence strengthens defenses for every device on the network.

• Ultra-light & efficient — kernel-level protection with no performance trade-off, built for resource-constrained hardware.

Flexible deployment — available as a Linux software firewall (Yocto, Ubuntu Core, Alpine), a plug-and-play gateway hardware device, or a C-based embedded library for RTOS and custom firmware. Delivered through mobile-provider, IoT/OT integrator/MSSP, and OEM partnership models.

NanoFirewall is the autonomous prevention pillar of AST's broader platform — enforcing preemptive blocking at the perimeter, edge, and embedded device level, fed by deception telemetry (BaitHive) and predictive threat intelligence (CATIS). Together they form what Gartner describes as an Autonomous Cyber Immune System (ACIS): the ultimate evolution of preemptive cybersecurity.
