Industry challenges right now

Interoperability and integration complexity
Many IoT and automation solutions involve diverse protocols, legacy systems, and vendor-specific technologies

Clients struggle with seamless integration across devices, networks, and platforms

Shortage of Skilled Engineers & Expertise
Finding embedded engineers, IoT specialists, and wireless communication experts is a growing challenge

Companies struggle with firmware development, real-time OS, and optimising hardware-software interactions. Expertise in low-power design, RF engineering, and security is often scarce

Security & Compliance Risks
IoT devices are a cybersecurity weak point, often lacking proper encryption and update mechanisms. Compliance with GDPR, NIS2, and sector-specific standards (e.g., ISO 27001, IEC 62443 for industrial IoT) is a major hurdle

Scalability & Performance Bottlenecks
Wireless networks face latency, congestion, and bandwidth limitations when scaling. Energy efficiency and battery life for IoT devices remain critical challenges

Tech evolution we do in 2025

AI-Driven Computing & Embedded Intelligence
AI/ML models running on low-power embedded systems, enabling real-time analytics, predictive maintenance, and anomaly detection

Private 5G & Next-Gen Wireless Networks
Enables ultra-reliable, low-latency communication (URLLC) for mission-critical automation and IoT

Standardisation & Open IoT Ecosystems
Faster deployment, fewer vendor lock-ins, and more secure, standardised industrial IoT solutions.

Zero Trust & Embedded IoT Security
Cyberattacks on IoT devices are increasing, requiring built-in security from hardware to cloud

Energy-Efficient & Sustainable IoT Technologies
Energy harvesting IoT, sensors, edge devices, and industrial automation that enables longer-lasting industrial deployments with minimal maintenance
