How about having a chart that provides you with the average time it takes for your team to remediate vulnerabilities according to their severity? Thanks to the Mean Time To Remediate (MTTR) by CVSS severity bar chart, you can have these averages in days for critical, high, medium and low severity levels. 

Remember that you can find this chart in the Analytics section for your organizations, groups and portfolios. At Fluid Attacks, we always hope to help you better manage vulnerabilities so that you can achieve prompt remediation.
