"Amazed at how Key&Box cleaned up our inboxes, it isn't until you check properly you realise there's stuff in your inbox that probably shouldn't be there... no more, it's all handled in Key&Box now and I know it destroys itself when I no longer need it!"

"As a paralegal I often have to send confidential information to third-parties. Using Key&Box makes this super simple, I upload the file, grab the link and send it to the person. Knowing nobody can access it except the person I sent it to. Even better I know Key&Box can't even see it"

"I used to have people send me copies of bank statements on whatsapp. But it annoyed me it always saved to my camera reel, there were like 4 copies in the end in different places. I've completely eradicated this with Key&Box, and the fact I can easily export a PDF to upload to my CRM is fantastic"
