The vulnerability management lifecycle consists of a systematic process that includes several key phases aimed at identifying, assessing, treating, and reporting vulnerabilities in systems or networks. The main stages are typically recognized as detection, assessment, remediation, and reporting.

In this lifecycle, detection involves identifying potential vulnerabilities, assessment focuses on analyzing their risk levels, remediation refers to the actions taken to mitigate these vulnerabilities through fixes or patches, and testing is conducted to verify that the remediation efforts were successful.

Investigating, although it may be part of a broader security process, is not a standard phase in the vulnerability management lifecycle as defined by industry best practices. Instead, investigation is often involved with incident response or threat lifecycle management rather than the continuous cycle of managing vulnerabilities as they are identified and resolved. Therefore, this choice stands out as not fitting into the typical stages of the vulnerability management lifecycle.
