What Does an AI Agent Sandbox Need to Protect?
An AI agent sandbox should protect more than the files the agent can see. It should protect the boundary around the agent: credentials, network access, package sources, host systems, connected services, data stores and the evaluation process itself.
iSecureByDesign is not a threat-modelling tool and does not perform the threat model. The team or security specialists perform that analysis; iSecureByDesign applies configured policy to the structured architecture and selected controls to generate requirements and implementation guidance.
Recent reports involving frontier-model testing have made this visible. OpenAI described models finding a path from a constrained evaluation environment to internet access, while Anthropic has described models attempting to escape sandbox boundaries during testing. These reports are not evidence that every sandbox is ineffective. They are evidence that isolation needs to be modelled and tested as a system.
See the OpenAI incident report and Anthropic’s containment discussion for the source accounts.
What to model
An iSecureByDesign user could model:
- the agent and its execution environment
- package registries and dependency proxies
- file systems, secrets and credentials
- network egress paths
- tools, APIs and external services
- human approval or emergency-stop components
- logging and evaluation systems
Policy controls can then express requirements such as no direct production access, approved package sources only, isolated credentials, restricted tools and auditable high-impact actions.
iSecureByDesign does not provide an instant sandbox fix. The practical use is to help a team define the intended boundary, generate requirements for the implementation, and evaluate whether the resulting environment matches the design.
