Your connected devices are the
attack surface your IT team
cannot see.
Most IoT and OT security assessments miss the hardware layer entirely.
SIRI Security's IoT and hardware practice conducts specialist embedded security assessments — firmware extraction and analysis, hardware interface testing (JTAG, UART, SPI), radio frequency security testing, OT/ICS protocol analysis, and connected device penetration testing — backed by legal authority and CERT-In compliance advisory.

Overview
IoT & Hardware Security Testing: Technical Depth Meets Legal Oversight
IoT security is fundamentally different from application or network security. Devices often lack security update mechanisms, use hardcoded credentials, transmit data over unencrypted radio protocols, and expose debugging interfaces that were left enabled after manufacturing.
Our hardware security team brings hands-on expertise in embedded systems — including binary reverse engineering, firmware extraction via JTAG and UART interfaces, and protocol analysis across Bluetooth, Zigbee, Z-Wave, BLE, and LoRa.
We assess devices in your real operating context — not just in isolation — to understand how a compromised device could be used to pivot into connected backend systems or affect operational processes.
AI-Powered Edge Device Security
AI inference is moving to the edge — devices running on-device ML models, computer vision pipelines, and embedded neural networks face unique attack vectors including model extraction, adversarial input attacks at the hardware level, and side-channel attacks against inference computation.
We assess AI edge devices against both traditional IoT attack vectors and emerging AI-specific threats, including physical adversarial attacks on camera-based ML systems and model extraction from edge inference hardware.
of IoT device vulnerabilities discovered in SIRI assessments were not detectable through standard network scanning — they required hardware-level testing
The devices you deploy are only as secure as the firmware inside them — which most security assessments never examine.
Firmware vulnerabilities persist for years undetected
Hardcoded credentials, insecure bootloaders, unencrypted storage, and backdoor authentication paths in IoT firmware create persistent vulnerabilities that network scanning cannot detect.
OT networks assumed secure — increasingly exposed
Operational technology environments — manufacturing PLCs, SCADA systems, industrial control networks — are increasingly connected to IT networks, exposing legacy systems designed with no cybersecurity to modern threat actors.
Medical and critical device compromise has physical consequences
Vulnerabilities in medical devices, building management systems, and manufacturing control systems have physical safety consequences — with severe legal and insurance implications.
Supply chain attacks originate in hardware
Hardware trojans, modified firmware, and compromised supply chain components are increasingly used in sophisticated attacks. Without hardware-level inspection, organisations have no visibility into device integrity at scale.

Client Benefits
Why Clients Choose SIRI Law LLP
Real Hardware Expertise
We work with physical devices, oscilloscopes, logic analysers, and soldering equipment — not just software emulation. Real hardware assessment reveals real vulnerabilities.
Full Attack Surface Coverage
Device, firmware, wireless protocols, companion app, and cloud backend — we assess the complete attack surface, not just the device in isolation.
Medical Device & ICS Specialisation
Specialist knowledge of healthcare device regulation (MDR, FDA) and ICS security standards (IEC 62443) for regulated environments.
Responsible Disclosure Support
For consumer device manufacturers, we provide responsible disclosure advisory — helping navigate CVE reporting, vendor notification, and public disclosure timelines.
Why SIRI
IoT security backed by
legal authority and CERT-In compliance.
SIRI Security assessments are conducted under attorney-client privilege — meaning vulnerability findings in your IoT infrastructure cannot be subpoenaed in regulatory investigations or civil litigation. No other IoT security firm in India offers this protection.

CERT-In mandatory reporting obligations apply to critical infrastructure IoT incidents. SIRI manages the notification, investigative response, and regulatory follow-up simultaneously with technical containment.
How We Assess
Four stages from scoping to remediation.
A structured assessment methodology covering every layer of the IoT device attack surface.
Scoping & Threat Modelling
Device architecture review, interface identification, attack surface mapping, and threat model construction — defining the testing scope and establishing the highest-priority assessment targets.
Hardware & Firmware Testing
Physical interface extraction, firmware analysis, RF testing, protocol assessment, and network communication review — systematic testing across the full device attack surface with all findings documented under privilege.
Legal Risk Mapping
Each vulnerability mapped to: CERT-In reporting obligations, product liability legal exposure, customer contractual obligations, regulatory disclosure requirements, and insurance notification obligations.

The SIRI Difference
Without SIRI vs. With SIRI.
Standard penetration testing firm
Network scanning only
Standard penetration testing stops at the network layer — firmware vulnerabilities, hardware interfaces, and RF protocol weaknesses are not assessed and remain undetected
No hardware testing capability
Firmware extraction, JTAG/UART interface testing, and hardware analysis require specialist equipment and training that standard penetration testers do not have
Findings not protected by privilege
Security assessment reports from consulting firms are not protected by attorney-client privilege — they are discoverable in regulatory investigations and civil litigation
No CERT-In support
Critical IoT vulnerabilities in infrastructure trigger CERT-In mandatory reporting obligations. Penetration testers are not equipped to manage the regulatory notification and investigation process
