Dynamic fuzzing - medical devices, IoT firmware & embedded systems

Dynamic fuzzing for embedded targets - crash cases, not theoretical flags.

Static analysis misses runtime bugs. Penzzer drives malformed inputs into running firmware, medical devices, and CAN bus targets - and returns a minimized, reproducible crash case, not a theoretical flag. Medical device teams use it to surface safety-critical faults before submission. IoT engineers use it to find memory-safety bugs before shipment. Embedded security consultancies add it as a high-value dynamic-testing line alongside SAST and SCA.

Fuzzing, where it actually matters

Static analysis reasons about code. Penzzer attacks behavior: the running protocol, the firmware on the device, the message on the bus.

Medical devices

Drives malformed and adversarial inputs into connected medical devices and their protocols. Surfaces safety-critical crashes, memory faults, and parsing bugs before they reach a patient.

IoT firmware

Exercises firmware across ARM, MIPS, and other embedded architectures to find memory-safety and parsing bugs before shipping.

CAN bus & embedded

Generates and mutates bus traffic against ECUs and embedded controllers. Built for automotive and industrial targets.

Inside Penzzer

What a running campaign looks like in the product: the coverage-and-crash dashboard, plus Penzzer driving live targets across automotive, wireless, and firmware.

For the teams who build it, and the partners who deliver it.

For security & product teams

Add dynamic testing to the pipeline you already run. Penzzer fits alongside SAST and SCA. It finds the runtime issues a scanner cannot, and gives you reproducible test cases instead of theoretical findings.

Reproducible crash cases (not just alerts). Coverage across medical devices, firmware, and embedded buses. Built to run continuously, not as a one-off audit.

For partners

MSSPs, AppSec consultancies, and VARs: Penzzer adds a high-value dynamic-testing line to your services. The Apona channel program covers margins, enablement, and deal support.
