GitLab Self-Hosted
Notice
It is possible to add the Checkmarx One external IP addresses to the customer Firewall whitelist - For more information see Checkmarx One External IPs
In addition, if the code repository is not internet accessible, it is possible to configure the code repository IP address instead of its hostname during the initial integration with the code repository - as it is not resolved via DNS.
Overview
Checkmarx One supports GitLab integration, enabling automated scanning of your GitLab projects whenever the code is updated. Checkmarx One’s GitLab integration listens for GitLab commit events and uses a webhook to trigger Checkmarx scans when a push, or a pull request occurs. Once a scan is completed, the results can be viewed in Checkmarx One.
In addition, for pull requests, a comment is created in GitLab, which includes a scan summary, list of vulnerabilities and a link to view the scan results in Checkmarx One.
Notice
This integration supports both public and private git based repos.
The integration is done on a per project basis, with a specific Checkmarx One Project corresponding to a specific GitLab repo.
Notice
You can select several repos to create multiple integrations in a bulk action.
