Vantisso
A vertically integrated platform for running AI agents, from hardware isolation up to the native runtime
Vantisso is a vertically integrated platform for running AI agents in isolation and keeping them under control.Each agent gets its own KVM-backed Firecracker MicroVM for hardware-level isolation, a native runtime built in-house drives the agent inside it, and every credential stays on the host.
It brings a stack that has long been split between isolation sandboxes and agent frameworks into a single, self-contained software package, delivered for on-premises installation.
ARCHITECTURE — One Integrated System for Both Isolation and Performance
Vantisso builds every layer itself, from the hardware virtualization infrastructure up to the operations control plane.It consists of an execution domain isolated for security and a host control domain that governs it.
HOST OS — Control & Management Domain
GUEST VM — Agent Execution Domain
Execution isolated by virtualization, operated by the host
Agents run inside a VM created by the virtualization engine, while the control plane, orchestration, and MCP gateway that govern them live on the host.Even if an agent is compromised or misbehaves, the enterprise's core assets stay protected.
Purpose-built channels for host–agent communication
Vantisso designs each cross-boundary channel for its specific purpose and builds it in-house.Environment creation and snapshot recovery, task control, and security status signals each travel over the channel suited to them, keeping the performance cost of separation to a minimum.
Host-driven state management and snapshots
The host manages environment creation, recovery, and snapshots from outside the VM.Because it captures execution state directly rather than requesting it from the agent, it can restore an agent's execution to an exact point in time.
Why Vertical Integration
Until now, environments for running agents have fallen into two camps.An isolation sandbox gives you a secure place to run, but no runtime to drive agents inside it.An agent framework gives you the runtime, but no hardware-level isolation boundary.Either way, developers are left to build the missing half themselves.Vantisso integrates both layers from the ground up, so developers can focus on building their agent services.

Six Core Capabilities
Infrastructure Layer
Hardware-level isolation
Built on KVM-based Firecracker MicroVMs, Vantisso gives every agent its own isolation boundary.Even if one agent is compromised, its impact on the host and on other agents is blocked by design.
Full resource teardown
When an agent finishes its mission, its disk, network, and processes are released with nothing left behind.Every run starts from an uncontaminated state.
Fast provisioning and state recovery
A new execution environment is created in under a second, and with the warm pool it is ready to run in roughly 2 ms.Snapshot restore, including memory, finishes within 200 ms regardless of memory size.
Runtime Layer
Native agent runtime
It runs independently inside the VM with no dependence on third-party frameworks.It supports major commercial LLM providers and open-source LLM APIs, so you are never locked into a single model.
Multi-agent orchestration
Group formation, a shared feed, direct agent-to-agent calls, and liveness monitoring are built into the runtime.Even after an agent is gone, the Handoff channel passes its outputs on so long-running missions continue.
Zero-trust MCP tool gateway
Credentials stay on the host and are never injected into the VM.The agent sees only a tool catalog filtered for its profile, which blocks privilege theft and misuse by design.
