+#### Using OWASP behind a Proxy
+
+If you are behind a Proxy then the OWASP plugin needs to be told which proxy to use. You can set the `mavenSettingsProxyId` property in your settings.xml to the appropriate PROXY-ID (which is usually defined in the same settings.xml).
+
+``` XML
+<properties>
+  <mavenSettingsProxyId>MY-PROXY-ID</mavenSettingsProxyId>
+</properties>
+```
+
+Updating the OWASP vulnerability database can also be blocked by the PROXY blocking HTTP HEAD requests. To work around this you will need a command line option: `-Ddownloader.quick.query.timestamp=false`
