# Scanning Selected Repositories
Running a full scan triggers a system-wide process that consumes significant resources. During this time, the OX platform is partially unavailable. A selective scan is faster than a full scan. During the scan, you can view and filter applications in the Applications page.
Instead of waiting for the next scheduled scan or triggering a full scan across all applications, you can run a selective scan when you need to scan a specific application urgently.
For example, if you make changes to a repository during the day and want to scan it immediately, you can run a selective scan instead of scanning the entire organization.
> **Note:** You can use this option to scan only repositories that have already been scanned at least once.
When using selective scan, you can:
* Select up to five repositories.
* Include only code repository applications. Repository applications are those connected to source control systems such as GitHub, GitLab, Bitbucket, and so on.
* Review audit logs that record this scan activity for traceability.
**To scan selected repositories:**
1. In the **OX Security** platform, go to **Applications**.
2. Select up to 5 code repo applications and click the select repo scan button on the top bar.
