How Internxt protects your account
Internxt protects your data and account from hackers in various ways to ensure your files remain secure and accessible only to you.
Internxt security for your accounts focuses on the following methods:
- Secure password: Internxt offers a free strong password generator and password checker to set up your account with a password that is protected from brute force or dictionary attacks that could breach your account.
- Two-Factor authentication: Once you create your account, you can add additional security by connecting Internxt to your preferred 2FA app.
- Backup recovery key: Internxt’s zero-knowledge encryption means we cannot reset your password or decrypt your files because only you have the keys needed to access them, so you must download your Internxt backup key to avoid losing your files if you forget your password.
- Password hashing: A password salt is a random piece of data that is added to your password before it is hashed. This makes every password hash unique, even if two users choose the same password.
How Internxt protects your files
Internxt Drive has the following features to protect your files in the cloud.
Backups
All Internxt paid plans include cloud storage backups to protect from ransomware or if your original files are lost, deleted, or corrupted. In this case, you can recover your data from your backups via the Internxt desktop apps, available for Windows, Mac, Linux, Rclone, WebDAV, or NAS devices.
To ensure your backups are up to date, you can schedule your files to be backed up every hour and up to every 24 hours.
Antivirus
Internxt Antivirus is included with all Internxt plans and protects your files by detecting, blocking, and removing malicious software before it can infect your device.
The best antivirus software prevents malware from stealing, encrypting, corrupting, or deleting your files, helping keep your data safe from common cyber threats.
File versioning
Internxt Premium and Ultimate plans offer additional protection and security for your files to ensure you always have access to the copy of the file you want in case accidental changes are made.
If you accidentally edit, overwrite, delete, or corrupt a file, Internxt lets you restore an earlier version instead of losing your work.
Secure file sharing
Internxt Drive allows you to share large files privately and protected with zero-knowledge encryption, so your files are encrypted and secure before they leave your device. You can also add a password to protect shared files, and monitor and revoke access to files once they are shared.
You can send files via a secure link or email, allowing you to share large videos or other files easily via email or messaging apps.
Internxt also offers Internxt Send, a free file sharing service with the same zero-knowledge encryption for files up to 5GB.
Internxt encryption
Internxt released post-quantum encryption for its cloud storage in 2025, making it the first cloud storage with Kyber-512 and AES-256 encryption.
The U.S. National Institute of Standards and Technology (NIST) mandates that all traditional encryption systems (like RSA and ECC) be completely phased out and replaced with Post-Quantum Cryptography (PQC) algorithms by 2035.
By storing your files with Internxt Drive, you get post-quantum and zero-knowledge encryption for all plans. All files stored or shared with Internxt are encrypted on your device so only you can access your files.
Even if requested by law enforcement or other agencies, neither Internxt nor anyone else can access your files, as encryption keys are managed on your device.
Internxt’s advanced encryption therefore makes it the best encrypted cloud storage for all your files.
File sharding
Once Internxt encrypts your data, the file is divided into smaller pieces and distributed across multiple servers or storage nodes.
As no single server stores a complete copy of your encrypted file, it makes it significantly harder and close to impossible for an attacker to access or reconstruct your data, as they can only access a small piece of an encrypted file.
Data redundancy
Internxt’s cloud data centers are based in Europe, and multiple encrypted copies of these files are stored in different data centers for additional data redundancy and security.
This means if anything happens to one data center, such as a fire or power failure, your files are still accessible and available in the cloud.
How Internxt protects your data
European privacy laws
Internxt is based in Spain and therefore complies with GDPR, which is known as one of the best privacy laws to protect your personal information in the following ways:
- Gives users control over their data by allowing them to access, correct, delete, and transfer their personal information.
- Requires clear consent before collecting or processing personal data.
- Limits data collection so organizations only gather information that is necessary for a specific purpose.
- Requires organizations to protect personal data with appropriate security measures, such as encryption and access controls.
- Mandates data breach notifications so affected users and regulators are informed if personal data is compromised.
- Holds organizations accountable through strict compliance requirements and significant fines for GDPR violations.
Compliance
Aside from offering GDPR compliant cloud storage, Internxt offers multiple compliance certifications for businesses, healthcare, and enterprises because it meets the following compliance standards:
- ISO 27001: Covers information security management, helping organizations protect data through risk management, security policies, access controls, and continuous monitoring.
- SOC 2: Covers how service providers protect customer data by evaluating security, availability, processing integrity, confidentiality, and privacy controls.
- HIPAA: Covers the protection of sensitive health information by requiring safeguards for the privacy, security, and confidentiality of medical data.
So whether you need personal or enterprise cloud storage, Internxt offers a broad range of data protection for all industries and data.

Frequently asked questions
How does Internxt encrypt my files?
Internxt encrypts your files on your device before they are uploaded using end-to-end, zero-knowledge Kyber-512 and AES-256 encryption, ensuring only you have access to the encryption keys.
Each file is assigned a unique encryption key, split into encrypted segments, and uploaded securely to the cloud. When you access your files, the encrypted segments are downloaded, reassembled, and decrypted locally on your device, so your data remains encrypted throughout the entire process.
Where is Internxt based?
Internxt is based and operates in Valencia, Spain, and is GDPR compliant and follows strict European privacy laws to protect its users' personal information and content in the cloud.
What jurisdiction is Internxt under?
Internxt is subject to Spanish and European Union (EU) jurisdiction.
Headquartered in Valencia, Spain, Internxt operates under Spanish law and must comply with the General Data Protection Regulation (GDPR).
Spain is considered a privacy-friendly jurisdiction, with strong data protection laws and independent judicial oversight, making it a more privacy-focused alternative to providers based in countries subject to broader government surveillance laws.

Can Internxt see my files?
No.
Internxt can never see or access your files because it uses zero-knowledge encryption.
Your files are encrypted on your device before they're uploaded, and only you hold the encryption keys needed to decrypt them. This means Internxt cannot access, read, or view the contents of your stored files.
