Operating System

Maltego works on Windows 7, 8 and 10, Linux (various distributions) as well as OS X. As Maltego is Java based it should work on most operating systems.

Software Requirements

You will need a 64-bit version of the Java 8 run-time installed on your machine in order to use Maltego.

The Java 8 JRE is available for most popular operating systems, and we would recommend the Oracle JRE over OpenJDK.

Please note: Later version of Java (9, 10, 11) are not currently supported.

Hardware Requirements


  • 4GB RAM, 
  • Intel i3
  • 1MB Internet access
  • 720p display


  • 16GB RAM
  • Intel i7
  • 10Mb+ Internet access

When working with large graphs, it's best to have as much memory and CPU as possible. Adding new results to a large graph, as well as calculating new graph layouts require a lot of computing power.

A faster internet connection allows you to run transform more quickly, allowing you to run transforms on large graphs in less time.

Network Requirements

To load the Maltego splash page as well as the icons for transform hub items, Maltego will need to be able to connect to "http://www.paterva.com" on port 80.

In order to use the OSINT transforms on Paterva's public CTAS server, your client will need to be able to access the following servers on ports 443 and 8081:
