Internal Agents in Acunetix 360

In some organizations, some websites will only be available on the local network (and not on the internet). You can use our Internal Agent feature to scan your internal websites while the results remain on our Acunetix 360 servers.

You can install an internal agent in Windows, Linux, Docker, and OpenShift. For further information, see Installing Internal Agents.

The Internal Agents feature is available in both Acunetix 360 (On-Demand) and On-Premises.

Allowlisting Acunetix 360's IP addresses for effective communication

Acunetix 360 Web Application On-Demand and internal agents use certain IP addresses to communicate with one another.

In order for Acunetix 360 Web Application On-Demand to operate effectively, you need to allowlist certain IP addresses on your firewall and/or proxy servers to allow communication of different components, such as internal scanning agents.

Without establishing this communication, you may run into problems. For example, the scanner agent may not report all of its findings to the Acunetix 360 Web Application. Or, Acunetix 360 may not push the vulnerabilities to the on-premises integration endpoints, such as Jira. So, you need to allowlist the IP address for the components to communicate with one another, as needed.


It is strongly recommended to allowlist the IP addresses only if you plan to install any of the following components:

  • Internal Scanner Agent
  • Internal Authentication Verifier Agent
  • OnPremises Integrations, like Jira or CyberArk.
