- Runner-up
- Guardrails AI · 8.21/10
Scores higher than the pick on: Price / performance, Lock-in risk (higher = worse).
- When not to use the pick
- Programmable validators/rails in your own code — Guardrails AI or NVIDIA NeMo Guardrails; enterprise network-level AI security suite — Prisma AIRS.
- Lock-in / migration
- Runner-up Guardrails AI has lower stored lock-in risk (3 vs 5.5, 0–10, higher = more lock-in).
- Sourced price (no comparable unit)
Pick: no sourced price in this job's unit (no_sourced_price).
No cheapest SKU (no_comparable_unit_for_job). No price was invented.
- Free option
- No free resource lists this job. A cheap paid SKU is not a free option.
- Failure modes to watch
- Observability gap: Alert on a drop in trace ingestion and on certificate expiry for the trace host. Do not treat a missing trace as a successful quiet run.

Top pick (8.32) and #2 runner-up (8.21) are separated by 0.11 points (<= 0.35 weight-sensitivity band). Treat them as co-picks and use the workload tie-breaker rule below rather than the raw composite decimal.
Workload Tie-Breaker Rule: Programmable validators/rails in your own code — Guardrails AI or NVIDIA NeMo Guardrails; enterprise network-level AI security suite — Prisma AIRS.
Lock-in risk: higher = more lock-in (worse). Overall already inverts this dimension.
Depot pick for a dedicated prompt-injection firewall in front of any LLM. NeMo when you need programmable rails; OpenAI Moderation for free taxonomy flags. Check Point acquisition is real — product still has a public API.
