Comparison
aigis vs prismor
Verdict
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; pick prismor if prismor is a runtime firewall that safeguards AI frameworks against security breaches like prompt injection attacks and secret leaks. It supports Claude Code and Codex.
