OneDrive is a popular cloud storage service that offers a generous 5GB of free storage to personal users, and businesses can enjoy up to 1TB of storage with a Microsoft 365 subscription.
This free storage is a great starting point for individuals who want to store and access their files from anywhere, but it's also a concern for business users who may have sensitive data to protect.
To mitigate this risk, OneDrive uses a robust set of security features, including two-factor authentication and encryption, which can be enabled for all users.
Two-factor authentication adds an extra layer of security by requiring a second form of verification, such as a code sent to your phone, in addition to your password.
Built-in Security Features
Microsoft has built-in security features to keep your OneDrive data safe. These features include virus scanning on download for known threats.
OneDrive scans documents at download time for content matching an AV signature, updated hourly, using the Windows Defender anti-malware engine. This ensures that your files are protected from malware and other known threats.
Suspicious activity monitoring is another feature that helps prevent unauthorized access to your account. OneDrive will block suspicious sign-in attempts and send you an email notification if it detects unusual activity.
You'll receive an email notification if OneDrive detects an attempt to sign in from a new device or location, for example. This helps you stay on top of any potential security issues.
Ransomware detection and recovery is also a key feature. As an Microsoft 365 subscriber, you'll get alerted if OneDrive detects a ransomware or malicious attack. You can then easily recover your files to a point in time before they were affected, up to 30 days after the attack.
You can also restore your entire OneDrive up to 30 days after a malicious attack or other types of data loss, such as file corruption, or accidental deletes and edits.
Here are some additional security features you can use to keep your OneDrive data safe:
- Virus scanning on download for known threats
- Suspicious activity monitoring
- Ransomware detection and recovery
- Version history for all file types
- Password protected & expiring sharing links
- Mass file deletion notification and recovery
Data Protection
Data Protection is a top priority for OneDrive, with multiple layers of security in place to safeguard your files. OneDrive provides version history for all file types, notification and recovery options when a large number of files are deleted, as well as options to recover files following a ransomware attack.
To protect your data, OneDrive uses Transport Layer Security (TLS) encryption when data transits into the service from clients, and between datacenters. This ensures that your files are encrypted in transit and at rest.
OneDrive also enables you to control the flow of data outside of your organization with Data Loss Prevention (DLP) features. DLP detects confidential information in your OneDrive environment using data classification and machine learning techniques, and allows system administrators to set granular policies based on the type of information being shared.

Protects Your Data
OneDrive provides robust data protection features to safeguard your files. Data recovery is a breeze with OneDrive's version history, notification, and recovery options, even in the event of a ransomware attack.
You can create a strong password to secure your account, but it's just the first step. Check the strength of your password to ensure it meets the required standards.
Two-factor verification is a must-have to protect your account. This feature requires an extra security code whenever you sign in on a device that isn’t trusted, adding an extra layer of security.
OneDrive uses Transport Layer Security (TLS) encryption to protect data in transit. This ensures that hackers can't intercept and read data being transmitted between your systems and Microsoft data centers.
Physical protection is just as important as digital security. Microsoft's datacenters have limited access, with multiple authentication factors, on-premises security officers, motion sensors, and video surveillance to prevent unauthorized access.
Each file in OneDrive is encrypted at rest with a unique AES256 key. These unique keys are encrypted with a set of master keys stored in Azure Key Vault, providing an additional layer of security.
Here are some key features that help protect your data in OneDrive:
- Create a strong password and check its strength.
- Add security info to your Microsoft account.
- Use two-factor verification to add an extra layer of security.
- Enable encryption on your mobile devices.
- Subscribe to Microsoft 365 for advanced protection.
OneDrive's Personal Vault is a protected area that requires strong authentication or a second step of identity verification. This adds an extra layer of security to your locked files, keeping them safe even if someone gains access to your account or device.
Personal Vault also allows you to scan directly into the vault, store sensitive documents, and use BitLocker-encryption for added security.
OneDrive's data loss prevention feature enables you to control the flow of data outside your organization. It detects confidential information using data classification and machine learning techniques, and allows you to set granular policies to prevent data leaks.
Here are some key benefits of using OneDrive's data loss prevention feature:
- Detect and classify sensitive data in OneDrive.
- Set granular policies to prevent data leaks.
- Alert you of unauthorized sharing attempts.
Security Measures
OneDrive provides robust security measures to protect your files. OneDrive for Business is one of the safest cloud storage solutions when paired with good security habits.
To ensure security, OneDrive offers built-in protections, including access control, encryption, and link expiration. You can password-protect specific files and folders, and the OneDrive Personal Vault requires additional authentication methods to access data.
Data loss prevention (DLP) is a key feature of OneDrive for Business, which enables you to control the flow of data outside of your organization to prevent data leaks. DLP systems look for text formatting, metadata, and keywords found in sensitive documents, and you can set granular policies based on the type of information being shared.
OneDrive for Business uses transport layer security (TLS) encryption to protect data in transit, and only permits secure access via HTTPS. This ensures that your files are safe from unauthorized access.
Each file is encrypted at rest with a unique AES256 key, which is encrypted with a set of master keys stored in Azure Key Vault. This provides an additional layer of protection for your sensitive data.

File Sharing and Access
File sharing is a breeze with OneDrive, and it's more secure than sending attachments via email. Users can share files by right-clicking on a file and specifying an email address to share with.
OneDrive also offers flexible access controls, allowing you to restrict which devices can sync files. This is especially useful for organizations that want to ensure employees aren't syncing work files to unauthorized devices.
Here are the three categories of shared link access available in the OneDrive Admin Center:
- Anyone with the link can access the file
- Links are only accessible by users within the organization
- Only specific people the end user permits can access the link
You can also set permissions on how users can interact with a shared file or folder, such as making files read-only by default or enabling editing permissions.
Easy File Sharing
Sharing files with others is a breeze with OneDrive. Simply right-click on a file and specify an email address to share with for a more secure and efficient form of sharing.
You can share files of any size without worrying about size limitations, which is a huge advantage over email attachments. This makes it easy to share large files with colleagues or clients.
OneDrive also provides a feature to set permissions on how users can interact with a shared file or folder. You can make files read-only by default or enable editing permissions, giving you control over who can make changes.
Here's a breakdown of the different permission options:
This level of control gives you peace of mind when sharing sensitive information with others.
Seamless Windows Sync
