## What the models said about IRI FieldShield

- "IRI FieldShield masks structured data across databases and files... offers strong coverage at a mid-market price" (Claude Haiku 4.5, direct prompt, first choice)
- "IRI FieldShield is widely considered the best value option for budget-conscious companies." (Claude Haiku 4.5, budget prompt, first choice)
- "IRI FieldShield is the strongest low-cost commercial option mentioned in the results" (Perplexity Sonar, budget prompt, first choice)

## What the models said about Delphix

- "What to Avoid (Unless You Have Enterprise Budget) ... Excellent but expensive" (Kimi K2, paraphrase prompt, hard negative)
- "Delphix (Perforce) - while it is a comprehensive tool, it focuses on test data management and data virtualization as much as masking itself." (Llama 4 Maverick, negative prompt, soft negative)
- "without the steep learning curve and infrastructure costs associated with enterprise giants like Delphix or IBM InfoSphere" (Qwen 3.7 Flash, paraphrase prompt, soft negative)
- "or Delphix if you have a multi-database environment. Both offer the right balance of features, scalability, and pricing for mid-market needs." (MiniMax M2.5, direct prompt, first choice)
- "Go with Delphix if your bottleneck is database provisioning speed and your infrastructure budget allows for heavy virtualization tooling." (Gemini 3.5 Flash, comparative prompt, first choice)
- "Choose Delphix or Informatica for broad database support + DevOps/test data pipelines with virtualization and policy automation." (Muse Glimmer 30B, comparative prompt, first choice)
