Key Security Features
Client-Side Encryption
Data is encrypted locally before it ever touches the network. Comet compresses and encrypts files at the source, ensuring they remain secure during transit and at rest in their storage location. This architecture protects against 'man-in-the-middle attacks' and keeps data unreadable even if the storage destination is compromised.

Immutable Storage
Render ransomware ineffective with Object Lock supported cloud storage. Comet integrates with S3-compatible providers to create immutable backups using WORM (Write Once, Read Many) technology. Even with root access, attackers cannot delete or modify your backup data until the retention period expires.

Zero-Knowledge Privacy
Built on a strictly "Zero-Knowledge" architecture, your encryption keys are derived from your password and never leave your device. This ensures absolute privacy: neither Comet Backup nor your storage provider can ever access, view, or decrypt your file content.

Physical Isolation: Air-Gapped Capabilities
Don't rely on a single point of failure. Comet gives you the flexibility to send backups to local hardware and removable media. By disconnecting these drives after the backup completes (air-gapping), you create a physical barrier that no remote hacker can cross, ensuring you always have a clean copy of your data on hand.

FAQS
No. Because of our Zero-Knowledge design, we do not store your encryption keys. This ensures that no one, not even us, can access your files, but it also means robust password management is essential.
Yes. We recommend Two-Factor Authentication for the Comet Server admin interface to prevent unauthorized access to your backup environment.
Yes. Comet's Self-Hosted solution provides the necessary technical safeguards—including AES-256 encryption, access controls, and immutable storage options—to help you satisfy the data protection mandates of GDPR, HIPAA, and other regulatory frameworks.
Absolutely. Since Comet allows you to bring your own storage, you have complete control over data sovereignty. You can choose a storage region specific to your compliance needs (e.g., keeping EU data within EU borders).
