ZoomEye Data Reveals Scale of Exposed Juniper, Sophos, WatchGuard and Barracuda Devices

A cybersecurity analysis published on DEV Community used the ZoomEye search engine to measure internet-facing appliances from four major edge security vendors on 26 September 2026. Juniper led with 342,558 exposed devices, followed by Barracuda at 164,282, WatchGuard at 31,364, and Sophos at 19,609, though the Juniper figure is not directly comparable as it spans a broader product portfolio beyond firewalls. All three remaining vendors primarily serve small and mid-sized businesses and have each experienced notable remote access vulnerabilities in recent years. The analysis cautions that these figures likely undercount total deployments, since many administrators deliberately obscure device banners, meaning the data reflects organizations that have not actively hidden their presence. Security experts recommend that appliance owners verify firmware versions directly on devices, confirm whether management interfaces are publicly accessible, and subscribe to each vendor's advisory channel to stay current on patches.
