The strongest open-source defense stack — PromptGuard 2 (small, fast injection classifier), AlignmentCheck (catches goal hijacking mid-agent-trajectory), and CodeShield — free, self-hostable, and purpose-built for the agentic pipelines where indirect injection turns into data exfiltration; the only OSS option engineered for the full injection-to-exfiltration chain rather than single-prompt scoring.
Where LlamaFirewall falls short, per the models
- Claude You own all the glue — tuning thresholds, updates, dashboards, and incident response are yours, and AlignmentCheck needs a capable judge model, adding real latency and cost per agent step.

Top alternatives per the models: Lakera Guard · NVIDIA NeMo Guardrails · LLM Guard · Prompt Security
A focused open-source agent-security layer combining PromptGuard 2, goal-alignment checks for indirect injection and agent hijacking, and CodeShield for dangerous generated code; compelling for teams needing inspectable defenses without a commercial gateway.
Claude The most agent-focused open-source option — PromptGuard 2 lightweight injection classifiers, AlignmentCheck to catch goal-hijacked tool use mid-trajectory, and CodeShield for unsafe generated code, all free and self-hostable with no data leaving your infra.
Where LlamaFirewall falls short, per the models
- GPT It lacks the comprehensive DLP, agent inventory, policy administration, audit, and deployment tooling expected from a full production security platform.
- Claude A component library, not a product — no managed service, dashboards, or support, it demands engineering to assemble, and the small classifiers alone are bypassable without layered defenses.
