Abstract: In one embodiment, a device in a network generates a machine learning-based traffic model using data indicative of a particular node in the network attempting to retrieve content from a particular resource in the network. The device predicts, using the traffic model, a time at which the particular node is expected to attempt retrieving future content from the particular resource. The device causes the future content from the particular resource to be prefetched in the network prior to the predicted time. The device makes a security assessment of the prefetched content. The device causes performance of a mitigation action in the network based on the security assessment of the prefetched content and in response to the particular node attempting to retrieve the future content from the particular resource.
