Distributed network security service
A distributed network security service is disclosed. The disclosed platform comprises an external service that facilitates security operations for a private network. Data from nodes of the private network is received and analyzed by the service. An output is automatically generated by the service in response to a detected security event in the analyzed data that facilitates remediating the security event at least at one or more of the nodes of the private network, wherein a latency exists between the security event occurring on the private network and being remediated during which time an entity responsible for the security event has access to the private network before being blocked.

analyzing the received data at the external service;

analyze the received data at the external service;
detect from analyzing the data a security event in the private network; and
automatically generate an output from the external service in response to detecting the security event that facilitates remediating the security event at least at one or more of the edge nodes of the private network.
