IoT Development Services & IoT Security Solutions

Q: What are IoT development services?

IoT development services cover the full stack needed to build Internet of Things solutions hardware selection, firmware, connectivity (Wi-Fi, cellular, LoRaWAN, BLE, Zigbee, Matter), edge computing, IoT platform build, device management, IoT security, analytics, and the web/mobile applications that expose data to users. ISpectra delivers each layer in-house and binds them together with a secure-by-design architecture.

Q: What is IoT security?

IoT security is the discipline of protecting connected devices, the networks they run on, the cloud platforms that receive their data, and the applications that control them. It covers hardware root of trust, signed firmware, mutual TLS, secrets management, network segmentation, OTA update integrity, anomaly detection, and compliance with baselines such as ETSI EN 303 645, IEC 62443, NIST IoT, and PSTI. Our IoT security services address every layer.

Q: How much do IoT services cost?

Enterprise IoT development services typically range from $75K–$500K for a focused program (firmware + platform + pilot fleet), and scale with device count, connectivity complexity, and compliance scope. IoT consulting engagements start at $15K for strategy and architecture workshops. We offer fixed-fee milestone pricing with clear deliverables, and we'll price-scope your specific use case free during a discovery call.

Q: What is industrial IoT (IIoT)?

Industrial IoT connects machinery, sensors, PLCs, SCADA systems, and manufacturing equipment to cloud analytics while preserving OT safety boundaries. IIoT requires deep knowledge of OT protocols (OPC-UA, Modbus, PROFINET, EtherNet/IP), the Purdue security model, and standards like IEC 62443. ISpectra's IIoT practice bridges factory floor to cloud safely enabling predictive maintenance, OEE dashboards, digital twins, and cross-plant analytics without exposing OT to enterprise threats.

Q: Can you build a custom IoT platform or do we use AWS IoT / Azure IoT?

Both options are viable. For most clients we recommend AWS IoT Core, Azure IoT Hub, or Google Cloud IoT as the backbone because they handle scale, security, and OTA out of the box. For specialized use cases (sovereign data, sub-1ms edge, regulated OT), we build custom platforms on open-source stacks (ThingsBoard, Balena, EdgeX, Eclipse IoT). Our IoT consulting team helps you pick based on device count, latency, compliance, and total cost of ownership.

Q: How do you handle OTA firmware updates?

OTA (Over-The-Air) firmware updates are core to our IoT development services. We implement signed firmware with a hardware root of trust, A/B partition schemes with automatic rollback, delta updates for bandwidth efficiency, staged rollouts with cohort targeting, telemetry-driven pause/abort, and end-to-end audit logs. We've run OTA across fleets of 1M+ devices without a failed mass-rollback.

Q: What IoT protocols do you support?

On the device side: MQTT, CoAP, AMQP, HTTP/2, WebSocket, and LwM2M for standard IoT; OPC-UA, Modbus, PROFINET, EtherNet/IP, BACnet, KNX for industrial. For connectivity: Wi-Fi, BLE, Zigbee, Thread, Matter, Z-Wave, LoRaWAN, NB-IoT, LTE-M, 5G, and satellite IoT. On the backend: Kafka, Kinesis, EventHub, gRPC, GraphQL. We select based on range, power, bandwidth, and cost rather than forcing a single protocol.

Q: Do you do IoT security audits on devices we've already deployed?

Yes. Our IoT security services include independent audits of fielded devices firmware reverse engineering, fuzzing, hardware teardown, network traffic analysis, cloud/API pentesting, and OT/IT segmentation review. We deliver a prioritized remediation report against ETSI EN 303 645, IEC 62443, OWASP IoT, and regulatory requirements like UK PSTI, EU CRA, and NIST IoT.

Why IoT Security Matters

Every Connected Device is a New Attack Surface. Most Aren't Protected.

A 2025 Forrester study found that 67% of enterprises experienced at least one IoT-related breach in the past 24 months driven by weak device authentication, firmware vulnerabilities, and unsegmented OT networks. ISpectra's IoT security services and IoT development services bake security into every layer: hardware, firmware, network, cloud, and data with measurable risk reduction.

IoT development services engineers designing connected devices, edge computing gateways and industrial IoT solutions at ISpectra IoT lab — ISpectra IoT solutions spanning industrial IoT, connected product development, edge AI, and IoT platform engineering with security-by-design.

What Secure, Scalable IoT Delivers

+Secure-by-design devices hardware root of trust, signed firmware, mutual TLS, zero default credentials
+Edge computing sub-10ms inference on device, less bandwidth, lower cloud cost, offline resilience
+IoT platform & device management OTA updates, certificate lifecycle, remote config, fleet telemetry
+Industrial IoT (IIoT) OT/IT convergence, SCADA integration, Purdue model segmentation
+Predictive maintenance ML on sensor data that cuts unplanned downtime by 30–50%
+Compliance-ready ETSI EN 303 645, IEC 62443, NIST IoT, UL 2900, Matter, and PSTI alignment

What Insecure, Ad-Hoc IoT Looks Like

−Default credentials admin/admin still shipping in production on half the IoT market
−Unsigned firmware attackers flash malicious updates and own the fleet in one command
−Flat OT network office malware moves laterally and takes down PLCs, HMIs, and production lines
−No device inventory nobody can list every connected device, let alone patch it
−Cloud-only ML every inference round-trips to cloud, racking up bandwidth costs and latency
−Orphaned deployments devices installed 5 years ago with no OTA capability, now unpatchable
