MTTR - Mean Time to Respond/Remediate Home Cybersecurity Dictionary MTTR - Mean Time to Respond/Remediate MTTR is the amount of time it takes an organization to neutralize an identified threat or failure within their network environment. Threat remediation is the process organizations use to identify and resolve threats to their network environment. A threat is a malicious intrusion/infiltration into a system to steal information, negatively effect operations or damage hardware or software. Highly trained people ("eyes on glass") are the first means of reducing MTTR to add the human element and understand the processes and technology. Having processes, plans and defined responsibilities helps by building confidence and empowering the right groups to act and remediate.
