How Does OneDrive Secure Your Data?

OneDrive secures your data with 256-bit encryption for both at-rest files and those in transit. Microsoft also maintains real-time security monitoring, penetration testing, and standard operating procedures for how to deal with privacy breaches.

How Secure is OneDrive File Sharing?

Is Microsoft OneDrive safe for sharing files? Yes, it is safe. However, its file sharing is not completely secure as cybercriminals could obtain the shared link through phishing and keyloggers that intercept copy/paste information. Hackers could also compromise the accounts of people you’ve shared the document with.

How Secure is OneDrive for Business?

So, how safe is OneDrive for Business, Microsoft’s B2B cloud storage offering?

This version of Microsoft’s cloud-sharing platform uses the same encryption protocols as the personal version of the platform. However, those with administrator permissions could pose a risk to your sensitive data’s security.

Best Cloud Storage Alternative to OneDrive

Google Drive and Dropbox are good alternatives as they also use 256-bit encryption. Dropbox even has a native password manager that can help secure your account.

However, both platforms have risks. Malware can be introduced into your system through Google Drive and shared files. Because of their popularity, both Google Drive and Dropbox have been targeted by hackers in the past, although Google has more vulnerabilities than Dropbox.

Final Thoughts

As you can see, OneDrive is a generally safe but not foolproof cloud storage platform. While it uses one of the best encryption levels, cybercriminals can still get access to your data, especially if you share your files. The best way to protect your data is to restrict who you share your files with and enable two-factor authentication.
