Methods and systems are described whereby a server can forward a request from a device behind a NAT router to a system to determine if the request is suspicious. A server can receive a message via a network device, such as a NAT router, disposed at a location. The message can originate from one of a plurality of computing devices located downstream of the network device. The server can determine that the message originated from a compromised device and transmit a signal to facilitate execution of a first process on the computing devices located downstream from the compromised device, wherein, upon execution, the first process is configured to compare information located in a local storage of the computing device with a predetermined list of domains.

Process for identifying a compromised device

Method of limiting offending messages communicated over a network, such as but not limited to messages associated with Spam and DoS attacks. The message limiting optionally including limiting bandwidth or other communication capabilities associated with an entity communicating or facilitating communication of the messages.

Process for abuse mitigation

Systems and methods for sending/receiving improved in-browser notification messages are provided. The notification messages are overlaid on HTTP traffic on portfor IP addresses provisioned to receive the notification messages from various sources, including weather, emergency broadcast, and police stations. A load balancer within the end-to-end system allows HTTP traffic on portto be forked from non HTTP traffic on portto selectively insert notification messages. The notifications are inserted by an internet content adoption protocol (ICAP) server in communication with other devices within the system.

System and method for improved notifications

Systems and methods for sending/receiving improved in-browser notification messages are provided. The notification messages are overlaid on HTTP traffic on port 80 for IP addresses provisioned to receive the notification messages from various sources, including weather, emergency broadcast, and police stations. A load balancer within the end-to-end system allows HTTP traffic on port 80 to be forked from non HTTP traffic on port 80 to selectively insert notification messages. The notifications are inserted by an internet content adoption protocol (ICAP) server in communication with other devices within the system.
