# Tip Tuesday: Zero-Day Vulnerability Best Practices

Welcome back to **Tip Tuesday**, where we share a helpful tip from our Sonatype team to help you find more success with Sonatype solutions.

**A zero-day event is when a previously unknown vulnerability is discovered in a popular open-source component. This is often before the project has a chance to release a fix; giving the community no time to react and little options to move forward.**

**[Read these best practices](https://help.sonatype.com/en/zero-day-vulnerability-best-practices.html) to determine your best defense against 0-day events.**
