Where the realm of devices meets the world of people. Bifrost is the industrial IoT edge gateway that spans the chasm between edge sensors and cloud intelligence — delivering secure telemetry, encrypted, resilient, and engineered for the frontiers of industry.
Bifrost is not a prototype. It is a production-ready secure IoT edge gateway built on the ESP32 platform — engineered for high availability, uncompromising AES-256-GCM encryption, and seamless telemetry between the edge and the cloud. Every component, from firmware to backend, is designed as a cohesive whole.
AES-256-GCM hardware-accelerated encryption protects every industrial IoT telemetry packet from edge to server. Efficient binary serialization with advanced compression ensures data efficiency without compromising security. End-to-end protection for your secure IoT gateway, zero compromises.
WiFi, Ethernet (W5500), and LoRa (SX1276/78) provide layered communication paths. MQTT gateway security with TLS ensures uninterrupted encrypted data flow. Automatic failover keeps your telemetry streaming even when primary channels fail.
Dual RS-485 channels and RS-232 support connect to legacy PLCs, Modbus devices, sensors, and actuators. PCF8574-driven enable lines provide isolated, reliable control over serial communication in noisy industrial environments. Industrial IoT hardware built for the factory floor.
On-device telemetry buffering stores industrial IoT data in RAM and NVS during network outages. Three-tier recovery system ensures automatic reconnection. Data is never lost — only delayed until the bridge reforms.

In the old Norse tales, Bifröst was the trembling rainbow that stretched from Midgard, the realm of mortals, to Asgard, the home of the gods. It was not merely a path. It was the connection itself — the living bond between what is and what could be. Today, Bifrost is the secure IoT gateway that makes that same crossing possible between industrial edge devices and the cloud.
Heimdall stood guard at its gate. The bridge was never about permanence. It was about passage: creating a channel where none existed, making the impossible crossing possible. Bifrost is that channel for industrial IoT — an encrypted IoT gateway guarding every telemetry packet.
Bifrost carries that purpose into the circuitry of the 21st century. Your sensors, PLCs, and RS-485 legacy machinery are your Midgard. Your cloud dashboards, AI analytics, and fleet management are your Asgard. Bifrost is the secure telemetry gateway that connects them — AES-256-GCM encrypted, multi-protocol resilient, and engineered never to break. An industrial edge computing platform for the most demanding IoT deployments.
At the heart of every Bifrost industrial IoT gateway beats an ESP32 dual-core microcontroller — a proven, battle-tested platform chosen for its balance of performance, AES-256-GCM security features, and industrial edge computing reliability. Every peripheral is carefully selected and verified for mission-critical deployment.
The W5500 Ethernet controller provides deterministic wired connectivity over HSPI, while the SX1276 LoRa transceiver offers long-range wireless backup. Dual UART channels drive RS-485 and RS-232 interfaces for legacy equipment integration, all managed through the PCF8574 I/O expander for isolated, reliable control. This IoT edge gateway architecture ensures secure telemetry across every deployment.
Security is not a feature of Bifrost — it is the foundation upon which everything is built. From the moment data leaves a sensor to the instant it arrives in your dashboard, every byte is protected.
All telemetry payloads encrypted with hardware-accelerated AES-256-GCM. Unique per-packet nonces ensure IV reuse is impossible — even with identical plaintext. Tamper-proof by design: corrupted or altered data is detected and rejected automatically at the cryptographic level, before any application processing occurs.
Every device must complete a cryptographically verified handshake before joining the network. MAC-based identity verification ensures only authorized hardware can transmit or receive data.
SQLite database with encrypted sensitive fields. Hardware-backed password hashing for user credentials. Session-based authentication with 10-hour expiry. Your data is protected whether in motion or at rest.
Advanced serialization minimizes payload size while maintaining full data fidelity. Intelligent compression further reduces bandwidth usage. Efficient, encrypted, and elegant.
Live monitoring detects unauthorized access attempts, tampered packets, and anomalous device behavior. Instant alerts enable rapid response. Heimdall's vigilance, digitized.
Every access event, every command, every telemetry transmission is logged with timestamps and origin data. Complete accountability for compliance reporting, security investigations, and operational analysis.
Bifrost speaks a secure, compressed binary language designed for industrial reliability. Every telemetry packet is a masterpiece of efficiency — encrypted, serialized, and compressed for the harshest network conditions.
Every transmission wrapped in an unbreakable cryptographic envelope. Tamper-proof by construction — no payload can be modified in transit without detection.
Advanced binary encoding provides efficient, schema-less data serialization. Ideal for constrained IoT environments where every byte matters.
Specialized compression optimized for small IoT payloads. Minimizes bandwidth usage on LoRa and cellular networks while maintaining real-time performance.
Lightweight publish-subscribe protocol for real-time telemetry and command dispatch. QoS levels ensure delivery guarantees. TLS encryption on top of payload encryption for defense in depth.
REST API endpoints provide reliable backup when MQTT brokers are unreachable. Automatic failover with telemetry buffering ensures zero data loss during transient network failures.
