# Overview

Each confirmed vulnerability has a status. A vulnerability is a live record: its status, assignment, and supporting evidence can change as Antigen and your team work on it.

There are five statuses:

* **Open**: the vulnerability is openly exploitable and is not assigned to anyone working on it.
* **In progress**: an agent or a person is working on the vulnerability.
* **Remediated**: a fix is ready to verify.
* **Verified**: an offensive agent, such as tCell, has confirmed that the original exploit no longer succeeds.
* **Accepted risk**: your team has decided not to remediate the vulnerability.

On the Vulnerabilities page, you can view the same vulnerabilities as a board or a list. You can also [query them through the API](/docs/api/vulnerabilities) and [configure hooks](/docs/vulnerability-lifecycle/hooks) that respond when their status or assignment changes.

## What moves a vulnerability forward

The lifecycle is driven by [hooks](/docs/vulnerability-lifecycle/hooks). Hooks run when a vulnerability changes state or assignment. Antigen uses them to start its built-in triage and remediation workflows. You can use the same mechanism to connect your own agents and workflows.

Read [how triage works](/docs/vulnerability-lifecycle/how-triage-works) and [how remediation works](/docs/vulnerability-lifecycle/how-remediation-works) to see how the built-in workflows use the lifecycle.
