The possibility of an attack against you is real. Our experts will follow up on any signs of a compromise, found either by Endpoint Detection & Response, Network Security Monitoring, customer alerts, or information from third parties. We analyze new information, triage it, and check for plausibility. We examine the full extent of any compromise and work to prevent similar attacks in the future. OS-CERT incident response handlers have access to a worldwide network of peers and are thus able to act globally, minimizing impacts on customers.
