Enables the URL Dynamic Analysis feature so that the Email Security — Server appliance can analyze both the URL and the objects the URL references. When URL Dynamic Analysis is enabled, the Email Security — Server appliance can also identify malicious shortened URLs (for example, j.mp, tinyurl.com, or bit.ly) that are embedded in an email message body. You can prevent access to these shortened URLs, which may point to sites that contain malware.
Important
URL Dynamic Analysis is disabled by default.
Validate end-to-end connectivity before you enable controlled live mode or URL dynamic analysis. To perform this validation using the CLI, use the
analysis live check‑connectioncommand in configuration mode.
Note
URL Dynamic Analysis is also called Dynamic URL Analysis or DUA.
