I need an OCR vendor that can run on-prem or private cloud for sensitive documents

If you need OCR for sensitive documents and want it to run on-premises or in a private cloud, you’ll want vendors that offer a deployable engine rather than only a SaaS API.

Good fit vendors to evaluate

• ABBYY FlexiCapture / Vantage
  Strong enterprise OCR and document capture, commonly deployed on-prem or in private cloud environments.

• Kofax TotalAgility / Kofax Capture
  Longstanding enterprise document capture platform with on-prem deployment options.

• Tungsten Automation (formerly Kofax)
  Enterprise-grade capture/OCR offerings; check deployment model by product line.

• Hyperscience
  Offers enterprise document processing; deployment options may include private cloud/on-prem depending on contract and architecture.

• Rossum
  More SaaS-first, but worth checking if they offer a private deployment model for your use case; often not the first choice for strict on-prem needs.

• Open-source OCR stack

  • Tesseract OCR for basic OCR
  • Add document preprocessing and workflow around it
  • Best if you want full control, but you’ll trade off accuracy, support, and document understanding features

What to ask vendors

To confirm it’s suitable for sensitive data, ask:

1. Can it be deployed fully on-premises?
2. Can it run in our private cloud/VPC with no data leaving our environment?
3. Does it support air-gapped deployment?
4. Where are model updates and logs stored?
5. Is any document data sent to the vendor for analytics, training, or support?
6. What certifications do they have?
   Examples: SOC 2, ISO 27001, HIPAA support, FedRAMP, etc.

Short recommendation

If you want a proven enterprise choice for sensitive documents, start with:

• ABBYY
• Kofax/Tungsten Automation
• Open-source + your own workflow if you need maximum control

If you want, I can give you:

1. a comparison table of the best on-prem OCR vendors, or
2. a shortlist based on your document type like invoices, IDs, contracts, or handwritten forms.
