We recommend you re-visit your strategy if you use cloud based storage systems without 2FA in place to store files containing confidential or personal data. It’s a cloud based system.
As part of our compliance review we look at secure file sharing systems that mean you send the recipient an email link to access the file and this link can’t be shared with other contacts. Livedrive is an easy to use and very cost effective system (can be cheaper than other popular systems) with a large storage capacity.
