CUJO AI Detects Home Devices Used as Proxy Networks

LOS ANGELES, Sept. 30, 2026 /CourierPR/ -- CUJO AI, the global leader in network intelligence and cybersecurity solutions for network service providers (NSPs), today introduced a new capability that identifies the specific device in a subscriber's home network that is being used as a residential proxy. The capability pairs that device-level findings with activity classification (such as ad fraud or malware) with remediation guidance and real-time notifications, giving operators a complete path from detection to resolution for the first time.

Until now, operators could at best flag a suspicious IP address; they had no way to say which device was compromised, quietly monetized, or actively taking orders from someone else. Residential proxy networks quietly resell home internet connections to third parties, routing anonymous traffic through real subscriber IP addresses, usually without the subscriber's knowledge. Compromised devices, bundled SDKs in free apps, and "get paid for your bandwidth" schemes are the most common ways a household device ends up enrolled.

CUJO AI's new capability closes that gap. Running at the home gateway, it identifies which subscriber network is hosting proxy activity and pinpoints the specific device inside the home generating it, along with clear, device-specific remediation steps and real-time alerts so operators can act before the damage compounds.

For operators, the capability turns an invisible cost center into a manageable one: reclaiming bandwidth consumed by third-party traffic, protecting IP reputation, and giving frontline support a real root cause for slowdown complaints instead of a shrug. For subscribers, the specificity changes the nature of the conversation. Instead of a warning letter or account suspension, an operator can reach out with something genuinely useful: a device has been identified, here is how to fix it. Handled that way, an incident that would otherwise feel like a penalty becomes a demonstration of the operator looking out for its customers.

The capability is being introduced to CUJO AI's operator partners now, with coverage and remediation guidance expanding as the program scales.
