What’s yours is yours.

What’s shared should be yours to control. SuperFile wraps any file — PDFs, spreadsheets, presentations, videos, drawings and maps — in key-separated encryption your organization controls for life. Share with confidence, see exactly who has opened it, and revoke access at any time, even for copies already downloaded to a laptop or an external drive.

A regular file vs. a SuperFile.

Usually when a file leaves your hands, it's out of your control. With SuperFile, you stay in control for the entire life of the file.

report.pdf Regular file
  • Anyone it reaches can open it — forever
  • Every forward and copy escapes your reach
  • No idea who opened it, or where
  • You can't pull it back once it's out
  • A stolen copy opens like the original
  • Screenshots and screen recordings copy it freely
report.pdfs SuperFile
  • Only the people, teams and devices you name can open it
  • Access is checked live on every open, and every 6 seconds while it is open
  • Every open is logged — who, from where, when, and who was refused
  • Revoke in one click: web viewers go dark in about 300 ms, the Mac viewer within 6 seconds
  • A stolen copy is ciphertext — the key never travels with the file
  • Screenshots black on Mac and Windows hardware viewers; refused elsewhere
