M2M / IoT Security
When Machines Talk, Only Authorized Conversations Happen
M2M communication is predictable — and therefore highly defensible. Devices follow defined protocols, call specific endpoints at expected intervals, and send structured payloads. This predictability is a security advantage.
How It Works
Behavioral Profiling
Quicksand builds per-device and per-service baselines automatically. Identity credentials, request sequences, communication rates, and payload structures are learned over time. Deviations from established patterns are flagged without requiring manual rule creation.
High-Confidence Detection
Deviations from expected patterns are detected with high confidence. Unauthorized endpoints, unusual payload sizes, malformed data, and communication outside expected time windows all flag potential compromise or misconfiguration. Multiple signals are correlated to minimize false positives.
Autonomous Enforcement
No human review is needed for enforcement actions. Compromised devices are isolated before lateral spread can occur. Rogue endpoints are blocked instantly. There is no delay between detection and response — enforcement is automatic and immediate.
Protocol Support
Long-lived connections including MQTT, WebSocket, and custom protocols are monitored continuously. No connection cycling or periodic reauthentication is required. Quicksand understands persistent communication patterns native to IoT and industrial environments.
Key Outcomes
- Deterministic enforcement without human interaction
- Long-lived connection and protocol support
- Secure device and service communication
- Protection against rogue devices and lateral abuse
Used in industrial IoT, energy, manufacturing, and smart infrastructure environments.

Scenario
A manufacturing company operates thousands of connected devices across multiple production facilities. Sensors, controllers, and automated systems communicate continuously. A compromised device must be isolated before lateral movement occurs. Quicksand builds behavioral baselines per device and enforces automatically — no human review required for enforcement decisions.
