Ostorlab is a Security testing requires often chaining tools together, taking the output from one, mangling it, filtering it and then pushing it to another tool. Several tools have tried to make the process less painful. Ostorlab addresses the same challenge by simplifying the hardest part and automating the boring and tedious part.

To do that, Ostorlab focuses on the following:

  • Ease of use with simple one command-line to perform all tasks
  • Developer Experience through project documentation, tutorials, SDK and templates
  • Scalability and Performance by using efficient serialisation format and proven industry standard for all of its components

To do that, Ostorlab ships with:

  • A simple, yet powerful SDK to make simple cases effortless while supporting the complex one, like distributed locking, QPS limiting, multiple instance parallelization …
  • A battle-tested framework that has been powering Ostorlab Platform for years and used to perform complex dynamic analysis setup and demanding static analysis workloads running on multiple machines.
  • Performant and scalable design, thanks to the use of message queue with dynamic routing, binary and compact message serialisation with protobuf, universal file format using docker image and resilient deployment thanks to docker swarm.
  • A store of agents that makes it easy to use and discover tools to add your toolset.
  • An automated builder to take the hassle away of building and publishing.
  • A GUI to prepare and write down your tool collection setup.
  • Focus on documentation, multiple tutorials and upcoming videos and conference presentations.
  • A ready to use one-click template repo to get started.


For some tasks, like running scans locally, Docker is required. To install docker, please see the following instructions.


Ostorlab is shipped as a Python package on Pypi. To install, simply run the following command if you have pip already installed.

pip install -U ostorlab

Getting Started

To perform your first scan, simply run the following command:

ostorlab scan run –install –agent agent/ostorlab/nmap –agent agent/ostorlab/openvas –agent agent/ostorlab/tsunami –agent agent/ostorlab/nuclei ip

This command will download and install the following scanning agents:

  • agent/ostorlab/nmap
  • agent/ostorlab/tsunami
  • agent/ostorlab/nuclei
  • agent/ostorlab/openvas

And will scan the target IP address

To check the scan status:

ostorlab scan list

Once the scan has completed, to access the scan results:

ostorlab vulnz list –scan-id
ostorlab vulnz describe –vuln-id

The Store

Ostorlab lists all agents on a public store where you can search and also publish your own agents.
