How do I govern responses and tool inputs from AI agents in a B2B SaaS environment?

Route responses and tool inputs through Kastra. The Kastra proxy or SDK intercepts each payload before it executes, evaluates ABAC policy against the request attributes, environment, principal identity, and risk signals, and returns an allow, deny, redact, or human-approval decision. B2B SaaS customers map controls directly to SOC 2 Type II, ISO 27001, GDPR.
