Sandbox

Isolate agent execution from the systems around it.

Run agents inside controlled environments with explicit boundaries for files, network access, tools, secrets, runtime limits, and artifacts.

Agent runtime

Sandbox boundary

├─ filesystem rules

├─ network rules

├─ tool permissions

├─ secret access

└─ execution limits

Agents need space to work without unlimited access.

Production agents may run code, read files, call tools, create artifacts, and interact with systems. Sandboxing gives them a controlled workspace so useful work can happen without exposing everything around them.

Unbounded execution

→ unclear file, network, and secret access

Sandboxed execution

→ explicit boundaries and traceable outputs

Define what the agent can reach.

Filesystem

What files and directories the agent can read or write

Network

Which hosts, APIs, or services are reachable

Tools

Which tools can be invoked inside the run

Secrets

Which credentials are injected and when

Runtime limits

Time, memory, process, and execution constraints

Artifacts

What outputs can be retained, exported, or attached to traces

A workspace per run, with policy around it.

Each run should have a clear execution context: the deployment version, runner, inputs, available tools, scoped knowledge, active skills, injected secrets, and workspace boundaries.

Run workspace

├─ inputs

├─ temporary files

├─ tool outputs

├─ generated artifacts

└─ logs + trace events

Keep useful outputs without leaking the workspace.

Agents often produce files, logs, summaries, reports, patches, or intermediate outputs. sypho helps separate retained artifacts from temporary execution state and records artifact activity in the run trace.

Why teams sandbox agents through sypho.

Safer execution

Limit file, network, tool, and secret access per run.

Cleaner boundaries

Separate temporary workspace state from retained artifacts.

Environment control

Apply different sandbox rules across local, production, customer cloud, or on-prem.

Traceable outputs

Record generated artifacts and workspace activity in run traces.

Production confidence

Let agents work with real systems without giving them unrestricted access.

Sandboxing protects execution.

Give agents room to work — with production boundaries.
