UnverifiedFirecracker can start a microVM with an independent kernel in milliseconds, preventing malicious code from escaping while avoiding the heavy startup overhead of traditional virtual machines.78% similarUnverifiedAgent sandboxes are typically based on lightweight virtual machine (microVM) technology, such as Firecracker or Cloud Hypervisor, providing complete kernel isolation at the hardware virtualization level.77% similarUnverifiedFull virtual machine isolation provides the strongest security boundary but has higher startup time and resource overhead, while process-level isolation offers excellent performance but exposes a larger shared kernel attack surface.73% similarUnverifiedgVisor intercepts system calls through a user-space kernel, while Firecracker provides micro-VM-level strong isolation based on KVM; both seek a balance between security and startup speed and are suitable for Agent services sensitive to cold-start latency.72% similarVerifiedSandbox isolation technologies include gVisor and Firecracker microVMs, used to ensure that AI-executed code does not affect the security of the host system.70% similar
