About Sync cloud storage
Sync cloud storage is based in Canada and has been in the cloud storage market since 2011.
The company provides online storage for individuals and businesses to securely save, access, and share their files across multiple devices.

Is Sync Cloud secure?
Sync Cloud has security features included in its free plan to ensure your account is protected. It also includes other security features for paid plans, should you need extra security for your team or personal files.
However, Sync is not open source. This is a major drawback for users who care about security and privacy, as Sync’s platform cannot be verified for its security, so you have to trust the company that it protects your data.
Free security features
- Zero-knowledge encryption: Sync cannot access your files, as everything is encrypted on your device. This differs from other companies, such as Google Drive, and other companies like Icedrive or pCloud, where zero-knowledge encryption is a paid feature.
- Two-factor authentication: 2FA reduces the risk of your account being breached if your password has leaked online or someone attempts to hack your account.
- Password-protected sharing: Shared links can be locked with a password so only approved users can access them. However, there are restrictions on the number of downloads and transfers.
- Remote device and session control: Log out devices or sessions if you suspect someone else has access.

Paid features
- Extended file versioning and recovery: Increases the recovery window of changed files to several months, giving stronger protection against accidental changes or deletion.
- Account rewind: Allows you to restore your entire account to an earlier state after incidents like ransomware or accidental deletion.
- Administrative controls for teams: Enable role-based access and user management to control who can access what to avoid unauthorized access to sensitive files.
- Compliance support: Sync is based in Canada, so it mostly follows Canadian regulations, but if you’re from Europe, then GDPR regulations apply. Sync also has SOC and HIPAA compliance, with the latter being a paid feature.
Advantages:
- Free zero-knowledge encryption
- Includes basic security for free plans
Disadvantages:
- Advanced security features are locked behind a paid plan.
- Security features are limited to cloud storage only.
- Cannot verify security claims, as Sync is not open source.
