IoT Penetration Testing Providers
IoT penetration testing evaluates the security of Internet of Things devices, their firmware, communication protocols, cloud backends, and mobile companion apps. This holistic approach examines the entire IoT ecosystem for vulnerabilities that could allow attackers to compromise devices, intercept data, or use IoT devices as entry points into corporate networks.
Testers analyse hardware interfaces (JTAG, UART, SPI), extract and reverse-engineer firmware, examine wireless protocols (Bluetooth, Zigbee, LoRa, Wi-Fi), test cloud APIs and management platforms, and assess the security of update mechanisms.
IoT pen testing is critical for manufacturers of connected devices, organisations deploying IoT at scale, and critical infrastructure operators. Common vulnerabilities found include hardcoded credentials, unencrypted communications, insecure firmware update mechanisms, and weak authentication. As IoT devices proliferate across industries from healthcare to manufacturing, ensuring their security is vital for protecting operational technology environments and preventing large-scale compromises.

IoT Penetration Testing FAQs
What types of IoT devices can be pen tested?+
Any connected device can be tested including industrial sensors, medical devices, smart home products, automotive systems, wearables, and building management systems.
Do you need physical access to the device?+
Hardware testing requires physical access for interface analysis. Remote testing can cover cloud backends, APIs, and network communications, but physical access enables the most thorough assessment.
What IoT-specific vulnerabilities do testers look for?+
Testers look for hardcoded credentials, insecure firmware updates, unencrypted communications, exposed debug interfaces, weak authentication, and vulnerabilities in wireless protocols.
