Product Penetration Testing

Find vulnerabilities before they become product failures, regulatory obstacles, or customer security incidents.

Traditional information technology penetration testing doesn't tell the whole story when the target is a medical device, industrial controller, gaming platform, laboratory instrument, or embedded component.

The Product Security Guild performs specialized penetration testing for products operating in regulated, connected, and safety-critical environments. We evaluate how attackers could exploit hardware, firmware, software, communications, and supporting infrastructure, not just whether a vulnerability scanner reports a weakness.

From early development through product launch and ongoing maintenance, our testing helps manufacturers understand realistic attack paths, verify security controls, prioritize remediation, and develop defensible technical evidence.

Build Secure. Build with the Guild.

Discuss Your Penetration Testing Needs
Beyond Vulnerability Scanning.

Testing That Reflects How Your Product Works.

Products have different architectures, interfaces, deployment environments, and consequences of failure. Effective penetration testing must account for those differences.

We combine manual security testing, targeted automated analysis, and product-specific attack scenarios to evaluate vulnerabilities across the complete product ecosystem.

Embedded Systems & Firmware Penetration Testing

Examine firmware, bootloaders, embedded operating systems, update mechanisms, debug interfaces, memory protections, and cryptographic implementations. Identify weaknesses involving insecure firmware updates, exposed credentials, authentication bypass, firmware extraction, and unauthorized code execution.

Hardware & Physical Interface Security Testing

Evaluate exposed interfaces, hardware trust boundaries, and physical attack surfaces. Testing may include Joint Test Action Group (JTAG) interfaces, Universal Asynchronous Receiver-Transmitter (UART), Serial Peripheral Interface (SPI), Inter-Integrated Circuit (I²C), and other diagnostic or service connections.

Wireless & Radio Frequency Penetration Testing

Assess Bluetooth Low Energy (BLE), Wi-Fi, radio frequency (RF), Near Field Communication (NFC), and proprietary wireless protocols. Investigate pairing, authentication, encryption, replay protection, unauthorized commands, and communications integrity.

Web, Mobile, Cloud & API Penetration Testing

Test connected applications and services for authentication weaknesses, authorization failures, insecure session management, exposed application programming interfaces (APIs), data leakage, cloud misconfigurations, and vulnerabilities that could compromise connected products.

Protocol Security Testing & Fuzzing

Evaluate how products handle unexpected, malformed, or unauthorized communications. Protocol analysis, fuzz testing, and targeted security assessments help identify parsing weaknesses, improper input validation, denial-of-service conditions, and failures in communications security.

Security Control Verification & Retesting

Determine whether implemented controls withstand realistic attacks. We document findings, evaluate potential impacts, support remediation decisions, and retest corrective actions to produce evidence of the resulting security posture.

Penetration Testing for Your Industry

A medical device, a casino gaming system, and an industrial controller may share common technologies, but they don't share the same attack surfaces, operational risks, or security expectations.

The Guild tailors penetration testing to the product's architecture, intended use, deployment environment, and applicable regulatory and customer requirements.

Our testing combines technical depth with an understanding of the environments in which products must operate.
