Case Study: Sonos achieves a secure launch of its Move voice-enabled speaker with Bishop Fox

Sonos Makes Secure Moves with Bishop Fox

Sonos, a leading consumer electronics company, was launching its voice‑enabled Move speaker and needed to ensure new hardware, Bluetooth/USB interfaces, microphone functionality and cloud/API integrations didn’t expose customers to risks like eavesdropping. To validate security across this complex attack surface and meet Alexa Voice Service requirements, Sonos engaged Bishop Fox for a Product Security Review.

Bishop Fox ran an in‑depth, white‑box assessment—onsite hardware testing with specialized tools, an agile Kanban workflow, and tailored testing across USB‑C, Bluetooth, the bootloader, mobile apps and cloud APIs—and even developed an active exploit to demonstrate real risk. Bishop Fox discovered one critical vulnerability (not found by other reviewers) that was relatively easy to fix, plus several medium/low issues, and confirmed the Move was otherwise highly resilient—helping Sonos prioritize remediation, strengthen its security posture, and justify additional resources.
