How do you run untrusted code — without compromising your platform?
​As platforms grow more flexible and dynamic, sandboxing has become essential for running third-party or user-submitted code. But doing it securely and at scale? That’s where things get challenging — and interesting.
​Join us for an evening of real-world DevOps and platform engineering insights, featuring:

• ​Why sandboxing is critical in modern architecture
• ​How to implement secure, scalable sandboxes in practice
• ​Tools, patterns, and tradeoffs from teams who’ve done it

​Speakers:

• ​Erik Lindblad – Lovable
• ​Mikael Knutsson – Molnett
