Any user of this or that cloud storage can pose a perfectly valid question: ‘Are my documents safe?’ or ‘What measures can I take to protect my sensitive information?’ Our answer to the first question is unconditionally affirmative, and if this is not enough, you can additionally protect your documents with two-factor authentication in your Encrypted folder.
