Well i forgot to mention that I am already using dedicated servers provided by my office to access office resources and yes we have also placed different SOPs for communication over such platforms.
As communication is not encrypted but files can, so we place passwords on documents and folders before sharing them, so if they get leaked, then it might not harm us as decryption of those keys is quite a difficult procedure and only professionals can access them.
Plus we are also using Lastpass
for password sharing, so passwords can't be leaked.
But I am bit worried about the zip files, as there are certain files and folders that takes more spaces so we share them by converting them to zip files and password protect them by using the procedure provided in this guide on how to password protect a zip file
, but are these only methods reliable?
Or is there any other alternative way to send big data encrypted?
