A small business owner receives a letter from her bank: her payment systems have been compromised. The breach came through a networked printer that nobody thought to update or monitor. The printer was connected to everything. It was secured by nothing.
The Internet of Things has connected billions of devices to corporate and personal networks — CCTV cameras, smart thermostats, medical monitors, industrial sensors. Most of these devices have minimal security, no update mechanism, and no monitoring. Each one is a potential entry point.
This system addresses the IoT security gap directly — using blockchain to create an immutable audit trail of every device interaction on the network, and intelligent monitoring to detect and respond to anomalous behaviour before it becomes a breach.
Traditional network security was designed for computers and servers. IoT devices — which now outnumber traditional endpoints by a factor of four — operate on different protocols, update infrequently, and are rarely monitored. They represent an expanding, largely unguarded attack surface that conventional security tools are not designed to address.
The system monitors all IoT device activity on the network, records interactions on a blockchain ledger for tamper-proof auditability, and applies intelligent analysis to detect anomalies — flagging unusual communication patterns, unauthorised access attempts, and behaviour that deviates from each device’s established baseline.
The system discovers and catalogues all IoT devices on the network, establishing each device’s normal communication patterns — what it talks to, when, how much, and using what protocols — building an individual baseline profile for each.
Like knowing every employee’s normal daily routine so that anything out of the ordinary is immediately obvious.
Every network interaction by every IoT device is logged in real time and written to the blockchain — creating a timestamped, tamper-proof record of every communication that cannot be altered, deleted, or disputed.
Like a CCTV system for your network that stores footage on a blockchain — the recordings can never be edited.
When a device behaves outside its baseline — communicating with an unusual destination, sending an abnormal data volume, activating at an unexpected time — the system flags the anomaly and alerts the security team with the specific device, the specific deviation, and a risk assessment.
Like a bank fraud alert that fires the moment your card does something it’s never done before.

Most network security products treat IoT as a category of endpoint — applying the same monitoring tools to a smart thermostat that they use for a laptop, which misses the specific threat model. This system is built from the ground up for IoT: device-specific baseline profiling, blockchain immutability for forensics, and interaction-level monitoring rather than traffic-level monitoring. The innovation patent covers that specific IoT-first, blockchain-anchored security architecture.
