NetFoundry Puts AI Agents Behind Kernel Firewalls

This is a compelling infrastructure-level answer to a problem traditional firewalls cannot solve: network identity is too coarse when an agent and trusted service share an interface.

• –Per-executable enforcement is stronger than container-wide allowlists because downloaded scripts cannot inherit the container’s permissions
• –Kernel-level controls sit below the agent, making policy harder to bypass through prompt injection or tool misuse
• –Deny-by-default networking reduces the blast radius of compromised agents, but requires careful allowlist maintenance
• –Structured logs containing process identity, executable path, destination, and verdict improve incident response and auditability
