What Agent Firewall is

Definition

SPENVERSE Agent Firewall is a control plane that authorizes agent actions before execution. Boundary: it does not replace your model provider, IAM, or GRC program.

Policy

Policy evaluation is deterministic with no LLM authority over the decision.

Emergency controls can freeze execution paths. This page publishes no latency figure for freeze propagation.

Category comparison

Compared with prompt filters and generic API gateways, Agent Firewall centers identity, authority, policy, approval, and tamper-evident evidence (hash-chained, signed checkpoints). Comparison is descriptive, not a ranking of vendors.
