Privio is your own platform where you can share your films privately and securely. It is really your own plateform with your own company logo.
Privio is just a technical interface with layered security you can manage without difficulty.
You can easily share content with your partners, in particular watermarqued files. You just need to send your content to Privio, Privio will then step in and deliver your file for a given time period and a list of viewers you can define beforehand.
This is called a Private Preview or Privio.
