Blast-Radius Isolation & Circuit Breakers
Agents are segmented with separate credentials and quotas, messages are validated, and breakers halt fan-out when error or anomaly rates spike.
Open in the interactive atlas →Impact
Stops one failing or compromised agent from taking the rest down with it.
Why this severity
Guardrails take the highest severity of the risks they mitigate: No Isolation Between Agents (High), Cascading Multi-Agent Failure (High).
Method: OWASP Risk Rating Methodology

Mitigates
- No Isolation Between Agents Vulnerability · High severity
- Cascading Multi-Agent Failure Threat · High severity
Builds on
- Agent Workload Identity & Signed Tasks Guardrail · Fixes medium risks
Remediation
- Segment agents by function and trust level.
- Trip breakers on error rate, cost spikes, or repeated identical actions.
- Escalate to a human when a breaker opens.
How to verify
- Breakers open within target time in fault-injection drills.
- Each agent's credentials are scoped and unique.
