Comparison
openfirma vs aigis
Verdict
Pick openfirma if openfirma is a policy-enforcing sidecar for AI agents that uses Cedar policies to gate outbound calls, built in Rust under the GPL-3.0 license; pick aigis if aigis is a deterministic zero-dependency Python firewall for AI agents offering protection against threats like memory poisoning and prompt injection with no external dependencies or complex configurations.
