Using MTTR to Improve Security Operations

Mean time to respond (MTTR) is an essential security metric to track when it comes to assessing the effectiveness of your security operations program. MTTR measures how quickly organizations detect and respond to threats, providing valuable insight into the overall state of security. In this blog post, we’ll discuss why MTTR is such a critical security metric and how you can use it to improve the security of your organization.

What Is MTTR in Cybersecurity?

MTTR is a cybersecurity metric that measures how long it takes for an organization to respond to and remediate a security incident or threat. It is a measure of the total time from when an incident is identified until it is resolved. MTTR metrics provide valuable insight into an organization’s security operations and can be used to identify potential issues or vulnerabilities in a network.

How to Calculate MTTR

The MTTR calculation is fairly simple: Divide the total time it took to resolve all incidents by the number of incidents that occurred during that time period. For example, if you had 10 incidents in a month and the total response time was 100 hours, then the MTTR would be 10 hours (100/10 = 10).

MTTR = (Total Incident Detection Time + Total Incident Investigation Time + Total Incident Resolution Time) / Total Number of Incidents

What MTTR Can Tell You
