smartlockr testimonial

"I noticed VKP employees were quick to adopt Smartlockr. When I check the portal, I can see it’s used a lot. I’m also happy to see two factor authentication being used avidly, for instance to send files securely to external parties. Smartlockr strikes a good balance between user friendliness and security."

This is what makes third party services for sharing your files insecure

You may have also used it yourself: a service with which you can exchange large files. Files up to 20G can be sent via the website, after which the recipient will receive an email with the files. Simple? Yes. Fast? Also. Safe? Not necessarily.


This is why:

  • There is no possibility to send files securely, with strong encryption such as zero-knowledge end-to-end encryption.
  • Files cannot be sent extra secured, through two-factor authentication.
  • No check on files before sending, so any incorrectly selected files would not be noticed.
  • Wrongly sent files can no longer be blocked afterwards.
