Comparison at a glance
| Aspect | Barrion | Probely |
|---|---|---|
| Scan type | Passive (read-only), production-safe | DAST, active scanning of apps and APIs |
| Use case | Continuous monitoring, misconfigurations, TLS/headers, compliance evidence | Vulnerability scanning in CI/CD or on-demand |
| Remediation | Step-by-step fixes per finding, PDF/CSV export | Findings with guidance, Jira/GitHub integration |
| Production | Read-only checks, built for production | Active DAST, so follow vendor guidance for production scans |
| Free tier | Free plan with core checks and up to 5 on-demand scans a day | Free trial, check current plans |
| Continuous AI pentest, checked against the live app | Yes. AI agents test your app on a schedule or on demand, and findings are checked against the live app before the report | Built as a scanner: DAST scans on a schedule or from CI/CD rather than a pentest |

Who Barrion is best for
Teams that want production-safe, continuous web app monitoring and clear remediation without active scanning. Barrion offers active testing through AI pentesting (self-serve, paid in credits) alongside its passive checks. Good for engineering teams and compliance evidence.
Who Probely is best for
Teams that want DAST in CI/CD or integrated with issue trackers and are comfortable running active scans in non-production or controlled environments.

Is Barrion a replacement for Probely?
For continuous monitoring, yes. Probely runs active scans against apps and APIs, often in CI/CD or on demand. Barrion's monitoring is passive and built for production, and its AI pentest, paid in credits, covers active testing on demand. If you want scheduled active scanning in a pipeline, Probely fits. If you want production-safe ongoing monitoring with step-by-step fixes, Barrion fits.
Can I use Barrion and Probely together?
Yes. A common pattern is Probely in the pipeline or staging for active DAST and Barrion in production for continuous monitoring and audit-ready evidence. They cover different stages and do not overlap.
