What Fuzzware is

Fuzzware provides rehosting-based security testing and automated fuzzing for embedded firmware without physical hardware. It analyzes compiled binaries, including closed-source and third-party firmware, without requiring source code. Campaigns examine complete firmware systems, including interacting components, interfaces, and execution paths. Its virtual execution environment handles peripherals, memory mappings, and execution contexts during analysis. The described workflow includes technical pre-validation, test scoping, an automated fuzzing campaign, and a detailed report. Reports contain contextual execution data, reproducible inputs, severity classifications, and coverage metrics. Fuzzware says firmware can be tested on every release to identify regressions and newly introduced vulnerabilities, with a repeatable process suited to CI-driven development. The FAQ names ARM Cortex-M and Infineon AURIX TriCore as supported architectures. Expert services include firmware audits, vulnerability verification, classification, and solution recommendations. The company presents the service for medical devices, automotive systems, critical infrastructure, and smart systems or IoT. Pricing is available on request.
