Edit SysML v2 models with Eclipse SysON, an open-source and web-based MBSE modeling tool.
An implementation of the OMG’s specification SysML v2: language concepts, REST API, and textual interoperability format
SysON was presented during the Vendor Roadmaps and Implementation Status session of the MBSE Workshop held as part of the INCOSE International Workshop 2025, in Seville, Spain, on February 1, 2025.
We're thrilled to share that we've already made significant progress toward our goals!
As demonstrated in the quick demo, SysON is up and running—packed with powerful features and designed with a strong focus on user experience.
The project is on the right track and is already generating considerable interest.

SysML was created in 2005 as a standard for model-based systems engineering (MBSE) to elevate the role of models as primary tools for communication and documentation.
With system complexity continuing to escalate exponentially, and Digital Engineering emerging as a pivotal pillar to address an ever-challenging world, SysML 2.0 has been specified as the next-generation systems modeling language to improve precision, expressiveness, and usability.
SysON’s objective is to provide System Engineers with super easy access to this new standard, at minimal cost and great ease of use, with the guarantee of interoperability with other open-source MBSE tools notably Capella and Papyrus.
This will be achieved through three means: the support of the SysML 2.0 standard, the use of state-of-the-art web technologies, and an open-source approach.
Are you currently preparing your or looking for a specific Markdown template to streamline your reporting process?
If you use Markdown, prepare a local compilation pipeline before the exam. Easily converts Markdown ( .md ) to PDF.
Good luck—and may your code traces be clear and your exploits be idempotent.
While the primary goal of the exam is to demonstrate exploitation ability, including professional remediation recommendations shows a well-rounded understanding of web application security. Provide specific, actionable recommendations for each identified vulnerability.
Many candidates fail the OSWE not because they lacked coding or exploitation skills, but because they treated the report as an afterthought. OffSec explicitly states that a professional report is required to pass.
Simply showing a Burp Suite exploit payload is not enough. You are being tested on white-box testing; you must point directly to the flawed logic inside the application's source files.
Ensure the script demonstrates the vulnerability effectively. 5. Tips for Finalizing and Submitting
Step 1: Code Review: Explain where you found the bug in the source code (screenshots required).
Create your .7z file containing the PDF and any auxiliary raw exploit scripts. Verify the archive using the password instructions provided in your official OffSec exam control panel.
Before you write a single line, you must understand the mandate from Offensive Security. According to the official exam guide, your OSWE exam report must include:

Obeo provides expertise to help you integrate SysON within your organization, and tailor or extend it to fit your needs.
Contact Us
Obeo is also preparing a secure cloud-based offering to provide SysON as a fully hosted SaaS solution, enabling users to access and use it without any deployment on their machines or servers.
Stay tuned…
Alongside the open source development of SysON, Obeo is working on advanced commercial features to support cutting-edge deployments for large-scale and/or mission-critical projects.
Stay tuned…The project team works in an iterative mode to deliver a new version every 8 weeks.
The first release of SysON, version 2023.12, was launched in December 2023 by Obeo and CEA List.
The SysON roadmap takes into account user feedback and needs identified as part of an Open Innovation approach.
For the next months, our main goals include:
In 2025, we will intensify our collaborations with industrial partners to elevate SysON to the forefront of SysML V2 modeling tool excellence
and prepare it for professional, operational, and large-scale deployment.
