# Working with unmatched CIs

As a Vulnerability Manager and Analyst, you can view and reclassify unmatched Configuration Items \(CIs\), reconcile unmatched discovered items, reapply CI lookup rules on the selected discovered items, and de-duplicate existing CIs.

See the CI matching in Vulnerability Response knowledge base article \[[KB0998706\]](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0998706) for more information about CI matching rule concepts and how CI matching works.

-   **[View and reclassify unmatched configuration items](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/security-management/vulnerability-response/view-discovered-items.md)**  
Configuration items \(CIs\) that are not found in the Configuration Management Database \(CMDB\) are placed in a viewable list of discovered items. This list offers a convenient way to reclassify unmatched CIs.
-   **[Reconcile unmatched discovered items](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/security-management/vulnerability-response/reapply-reconcile-unmatched-discovered-items.md)**  
Create a scheduled job to reconcile unmatched discovered items.
-   **[Steps to help prevent duplicate or orphaned records after running Vulnerability Response CI lookup rules](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/security-management/vulnerability-response/ci-identifier-rules-impl-test.md)**  
Take steps to help prevent duplicate or orphan records resulting from matching \(configuration items \(CIs\) within the CMDB.
-   **[De-duplicating existing configuration items](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/security-management/vulnerability-response/reapply-deduplication.md)**  
Whenever configuration items \(CIs\) are updated through a deduplication task, the discovered items \(DIs\) that are related to those CIs are also updated. The vulnerable items \(VIs\) and detections are also updated with the CI.
-   **[Resolve remediation tasks](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/security-management/vulnerability-response/remediate-vuln-groups.md)**  
The flexibility inherent in Vulnerability Response allows you to remediate vulnerabilities in whatever way suits your security organization.
