Most open source comes with no warranty. No SLA. No obligation to fix security issues. If you're running it in production, that’s a risk. Our guide explains what this means and how to prepare: bit.ly/49VyZbi #OpenSource #OSSSecurity #RiskManagement #SoftwareLifecycle

Open source risk rarely shows up at install time. It shows up later—when versions age, patches lag, and security vulnerabilities surface. Lifecycle planning matters. bit.ly/49VyZbi #OpenSource #OSSSecurity #SoftwareLifecycle
