Release Notes October 2021

Release Date: 2021-10-26


Important notice for all customers

We are continually improving the service we offer our customers, and are implementing a number of network changes to help improve the service we are able to provide.

To guarantee an totally uninterrupted service, we recommend that customers allow any Outpost24 services they may have running access to the following IP ranges:

  • For IPv4: to, to
  • For IPv6: 2001:67c:1084::0 to 2001:067c:1084:ffff:ffff:ffff:ffff:ffff.

As we know this is not always possible for some customers, in the last few months we have implemented DNS entries for all of our services where specific access is required. These may have previously been communicated as IP Addresses, but should be changed to DNS entries as soon as possible to ensure a continuity of service. The necessary changes are detailed below:



Inbound HIAB Rule91.216.32.3

Important notice for all XMLAPI users

XMLAPI queries now return a maximum of 5000 rows per query to ensure sustainable performance for all XMLAPI users.

New Features


Added the capability to scan using vulnerabilities

During the scan process we will often find ways for us to perform a more in-depth Vulnerability Scan using default credentials or null sessions. If credentials for a target are not specifically supplied, we can now use any discovered credentials to perform a scan with increased levels of authentication.

It is possible to disable this capability in the scan policy (Default: Enabled). Supplied credentials will always take precedence over discovered credentials.
