## 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 Oracle Data Masking and Subsetting

- "Oracle Data Masking and Subsetting is native to Oracle Enterprise Manager and only sensible if your estate is Oracle. Using it outside Oracle adds integration risk and limited coverage." (Muse Glimmer 30B, negative prompt, soft negative)
- "Best only if you're already an Oracle shop; not flexible for non-Oracle databases" (DeepSeek V4 Flash, negative prompt, soft negative)
- "Great if locked-in, but can't handle hybrid/multi-cloud without extras." (Grok 4.1 Fast, negative prompt, soft negative)
- "I'd suggest starting with Oracle Data Masking and Subsetting if you're in an Oracle environment, or Delphix if you have a multi-database environment" (MiniMax M2.5, direct prompt, first choice)
- "Oracle Data Masking and Subsetting is the best pick from these results for a typical mid-market B2B company" (Perplexity Sonar, direct prompt, first choice)
- "Start with Oracle Data Masking if you're in an Oracle ecosystem—explicitly called best for mid-size enterprises" (Grok 4.1 Fast, direct prompt, first choice)
