2026 Open Source
Landscape Report

Why do 61.4% of enterprise cybersecurity incidents happen when a patch already exists?

Is lack of visibility really the problem – or is it execution speed?

Those are just some of the questions we tackle in this year’s Open Source Landscape Report – our annual deep dive into how open-source software is actually used, secured, and maintained in production.

In this report, we investigate what’s changed, what hasn’t, and where risk is quietly building up. It’s a thrilling read for anyone who relies on open source (which is… basically everyone), and it’s especially useful for security leaders, platform teams, and open-source strategists inside larger organizations who need data to guide real-world decisions.

64.2%

of large organizations reported a cybersecurity incident in the past 12 months

15.9%

of enterprises knowingly run EOL software without updates

78%

aren’t fully confident about the security of their open-source components (incl. transitive dependencies)

This report tackles questions like:

Which languages, frameworks, and runtimes actually dominate real production estates today?
Do organizations actually track end-of-life (EOL) status for the software they use – or just find out when things break?
Which companies are most likely to get caught off guard by EOL?
What really slows vulnerability patching down – governance friction, tooling limits, uptime pressure, or dependency complexity?
Are organizations truly managing transitive dependency risk – or just scanning and hoping for the best?
Is transitive dependency risk driven more by the number of dependencies – or by how well teams can see and govern them?

(and many more!)

Why should you read this report?

You’ll get real-world insights directly from practitioners across security, DevOps, platform, and engineering – not theory, not vendor spin. If you’re responsible for open-source risk, uptime, or long-term platform strategy, this report shows where the gaps really are and how peers are navigating them.
