Let’s be honest. Secure development often feels like a maze of frameworks, checklists, and compliance requirements. Whether you’re wrangling with threat models or trying to keep up with the latest cybersecurity regulations, it’s easy to feel overwhelmed. But what if there was a way to cut through the noise and get started with secure development in a way that’s actually manageable?
Enter Cyberismo Secure Development Essentials, a new open-source content module designed to help development teams take control of cybersecurity from day one. And yes, it’s free.
What’s in the box?
This isn’t just another checklist. Cyberismo Secure Development Essentials module gives you, for example:
- Ready-to-use templates for threat modelling, security documentation, secure development tasks, and more.
- Automatically generated dataflow diagrams—no need to fiddle with drawing tools or learn new notations.
- Built-in KPIs to track your team’s progress and see where you stand.
- Smart linking between tasks, risks, vulnerabilities, and requirements, making it easier to manage complexity.
- Covers all phases of the secure development lifecycle.
It’s like having a cybersecurity coach baked into your development workflow.

Why it matters
If you’ve ever tried to implement secure development practices from scratch, you know how time-consuming it can be. Cyberismo flips the script by offering a modular, open-source solution that’s easy to adopt and extend. Start with the essentials module, and when you’re ready, plug in other modules. You can later extend your secure development practices with the Cyberismo EU Cyber Resilience Act module for products designed for the EU market, and with the commercial Cyberismo Secure Development Pro module for covering the IEC 62443-4-1 standard.
And because it’s open-source, you’re not locked into anything. You can inspect the implementation, use the bits that you like, or tailor it to your team’s specific needs.
Threat modelling without the headache
One of the standout features is the intuitive threat modelling tool. You model your architecture using a graphical user interface, and Cyberismo generates the dataflow diagrams for you. The result is stored as plain text, so you can version it like code. Perfect for teams already living in Git.
No domain-specific languages. No steep learning curve. Just practical tools that work.
Try it yourself
Cyberismo offers an online demo environment and documentation to get you started. You can also see the source code in GitHub, or videos of the module in action.
Whether you’re a seasoned DevSecOps engineer or just dipping your toes into secure development, this module is a solid starting point.
