Tackling Cloud Security Challenges In Runtime Environments
Security Boulevard, Monday, June 30th, 2025
Rinki Sethi, chief security officer for Upwind, unpacks why runtime is the new battleground for cloud defense.
Sethi traces her epiphany back to 2022, when she first heard that you can't secure what you can't see in real time. Configuration checks and compliance scans are fine, she says, but attackers still slip through unless you're monitoring live application behavior.
That conviction led her to technologies such as eBPF, which let vendors drop ultra-light sensors into production without dragging performance. Upwind was an early adopter, and the approach has since become a buzzword-but for good reason. Lightweight, kernel-level visibility makes it practical to watch containers, VMs, serverless functions and whatever AI workloads come next, even as environments grow more fragmented.
