Why Biffer beats
both extremes
Manual tools are slow. Cloud LLMs ship your documents to unknown servers. Biffer gives you both speed and control.
| Capability | Manual / Adobe | Cloud LLMs | Biffer recommended |
|---|---|---|---|
| Speed | Slow | Fast | Fast |
| PII accuracy | Medium | High | High |
| Data leaves org | No | Yes — always | Never |
| On-premise deploy | Yes | No | Yes |
| GDPR / HIPAA safe | Risky | Risk of breach | Full control |
| Bulk processing | Manual only | Yes | Yes |
| Air-gap support | Yes | No | Yes |
