What is a Maltego Standard Transforms Add-on (CTAS) Server?

Modified on: Thu, 6 Apr, 2023 at 9:54 AM

The Standard Transforms Add-on (CTAS) Server is a special server which hosts all of Maltego's Standard Transforms and executes these as requested through the Maltego Desktop Client.

CTAS stands for Commercial Transform Application Server.

The Standard Transforms Add-on (CTAS) Server includes Transforms for gathering OSINT from common sources on the Internet. This includes querying DNS servers, search engines, social networks, various APIs, and other sources. A full list of the Transforms included with the Standard Transform Add-on (CTAS) Server can be found in our Transform guide here.

Standard Transforms Add-on (CTAS) Server Transforms query the following data sources:

  • DNS Servers,
  • Search Engines,
  • Online Databases,
  • Social Networks (Flickr),
  • Online APIs,
  • Other Public Sources.

A Standard Transforms Add-on (CTAS) server allows you to host all of Maltego's Standard Transforms from within your organization. A Standard Transforms Add-on (CTAS) server is almost an exact copy of the Public Transform Server except that it can be hosted internally within your organization. This is specifically applicable to customers who prefer that their data does not travel over Maltego's infrastructure.

Why use a Standard Transforms Add-on (CTAS) Server?

Out-of-the-box Maltego Desktop Clients use Maltego's Public Transform Server to run Transforms that are located on the Internet and used by other Maltego users. A Standard Transforms Add-on (CTAS) Server is an on-premise server for customers performing sensitive investigations where their preference is to keep their Transform requests private. Although Maltego will never log the questions asked, nor their answers, when a Transform query is run on our Public Transform Server, some customers still prefer the peace of mind provided by hosting their own copy of our server.

You can see what is logged when a Transform is run on Maltego's Public Transform server here.

A Standard Transforms Add-on (CTAS) Server also includes a management console where the server status can be viewed as well as other basic server configurations that can be performed.
