Zero migration stress with our patented file migration technology

Data migration is usually the single biggest roadblock. Years of files that need to move without breaking anything. For most organizations, this is where timelines explode and costs spiral.

Qsentinel’s patented migration technology moves entire environments exactly as they are:

  • Full folder hierarchies
  • Permissions
  • Shares
  • Tags
  • Metadata

And we do it fast. No downtime, no disruption, no consultants draining budgets.

“If you’re in government, law, healthcare, or just someone who still believes in user freedom, data privacy, and decentralization, Qsentinel is what you should be looking at.”

Private AI that shatters the competition in confidentiality and performance

  • Choose from leading open-source models like Mistral and Llama.
  • Your data is never used to train any model. Period.
  • Process thousands of files at once and extract insights no public AI can deliver.

Private AI that shatters the competition in confidentiality and performance

Public AI platforms impose strict upload limits, break your workflow, and quietly feed your data back into their training pipelines. With QSentinel, none of that applies. You upload without limits, analyze entire document sets at once, and your files are never used to train any model. You keep full control.
