# Continuous Offensive Security (COS)

Snyk Continuous Offensive Security is an AI-driven pentesting engine that continuously tests your web applications, validates real vulnerabilities, and tracks findings over time.

Use the pages in this section to configure targets, run scans, and review findings.

### Assessment depth

Depth is determined by whether a source repository is linked. There is no separate setting to change.

| Depth        | Condition            | What you get                                                                                                                                                                           |
| ------------ | -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Blackbox** | No repository linked | Agents test entirely from the outside. Remediation guidance is generic to the vulnerability class, with references                                                                     |
| **Greybox**  | Repository linked    | Agents use source code to understand structure and reach logic flaws that are invisible from the outside. Remediation guidance names the file, the line, and the suggested code change |

Link repositories to help Snyk find more issues and provide more actionable guidance on fixes.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.snyk.io/agent-security/evo-by-snyk/continuous-offensive-security-cos.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
