491: The Future of Open Source Security with Aisle CEO Ondrej Vlcek | Destination Linux 491

November 9, 2026 · 1 h 16 min

Show notes

Open source is facing a security problem unlike anything we’ve seen before. Maintainers are overwhelmed, developers are drowning in low-quality vulnerability reports, and AI is making it easier than ever to search for weaknesses at scale.

In Destination Linux Episode 491, Ryan, Jill, and Zeb sit down with Aisle CEO and Co-Founder Ondrej Vlcek for a fascinating conversation about the future of open-source security.

Ondrej takes us through his journey into cybersecurity, his career at Avast, and what ultimately led him to co-found Aisle. From there, we dig into what’s broken with the traditional “scan, prioritize, and patch” approach, how developers can separate real threats from mountains of noise, and how AI is changing the battle between attackers and defenders.

We also explore how Aisle fits into developer workflows, who the platform is designed for, the challenges facing projects such as PHP, and what autonomous security could mean for open-source software.

Plus, Community Feedback takes us into a very different security and privacy debate: online age verification, TPM requirements, digital identity, older hardware, and the potential implications for Linux users.

And with Destination Linux rapidly approaching Episode 500, we want your ideas for how we should celebrate!
