Time to remediate (TtR) is a performance metric used in IT operations, cybersecurity, and software development to quantify how long it takes to address a detected issue until it is verified as remediated. It covers vulnerabilities, defects, misconfigurations, or compliance issues and can be tracked for individual incidents or summarized across a portfolio.

Calculation and data typically involve measuring the interval between the detection or identification timestamp and the remediation completion timestamp (validation that the remediation is effective). Data sources include issue trackers, vulnerability scanners, patch management systems, and change-management records. Some organizations break out TtR by severity, asset class, or remediation type to highlight where delays occur.

Relation to MTTR: TtR is closely related to the broader mean time to repair (MTTR) concept but is used specifically to evaluate remediation activities for security, software, or compliance issues. TtR can be complemented by related metrics such as time to detect, time to contain, or time to remediate, with per-asset and per-incident breakdowns to provide more granular insight.

Best practices and challenges: To improve TtR, organizations should establish clear ownership, automate detection and notification, maintain an accurate asset inventory, implement remediation playbooks, and integrate remediation with change management. Automated validation and testing help confirm fixes. Common challenges include incomplete data, backlogs, dependencies, third-party involvement, and environments with downtime constraints. Setting targets and monitoring percentile thresholds (for example, the 90th percentile) can help balance speed with safety.

Applications and scope: TtR is applied by security teams, IT operations, software development, and regulatory compliance programs to assess how quickly issues are resolved, prioritize resources, and reduce risk exposure. It is often reported alongside MTTR and other lifecycle metrics to provide a comprehensive view of remediation performance.
