Security forms a fundamental pillar of pCloud's offering. All data transferred between your device and the servers benefits from TLS/SSL encryption. Additionally, once stored, your files are protected by AES 256-bit encryption, considered one of the most secure currently available.
For enhanced protection, pCloud optionally offers the "pCloud Crypto" service. This system provides client-side encryption, meaning your files are encrypted before being sent to pCloud's servers. Consequently, even the pCloud team cannot access your document contents, as you alone possess the decryption key.
In terms of infrastructure, your files are stored on at least three different servers located in highly secure zones. This redundancy ensures your data remains accessible even in the event of hardware failure. In fact, pCloud maintains five copies of each file distributed across multiple servers.
Based in Switzerland, the company is subject to Swiss data protection laws, considered among the world's strictest. Users can choose the geographical location of their data, either in the United States (Texas) or the European Union (Luxembourg). The data centers used by pCloud are certified according to SSAE 18 SOC 2 Type II and SSAE 16 SOC 2 Type II standards.
To complete this security setup, pCloud offers two-factor authentication, adding an extra layer of protection for your account.
Free Storage Offered by pCloud
pCloud's free plan provides access to 10 GB of online storage space. However, this full storage capacity isn't immediately available upon registration. Users start with 4 GB and can unlock the additional 6 GB by completing simple tasks such as email verification, uploading a file, or installing the desktop application.

Free users also enjoy file version history retention for 15 days. This feature proves invaluable when dealing with accidental modifications or unintended deletions. The Rewind function complements this protection by allowing users to restore their account to a specific date and time within the previous 15 days for free accounts.
While the free plan provides access to most essential features, certain advanced sharing options like password protection and expiration dates are exclusive to premium accounts. Nevertheless, pCloud stands as a robust free cloud storage solution, particularly renowned for its multimedia capabilities and strict privacy policies.
Internxt
A pioneer in free online storage with post-quantum protection, Internxt is redefining cloud security standards in 2025. This Spanish service, created with the goal of absolute privacy, incorporates cutting-edge technologies to protect your data against current and future threats.
Internxt Features
Internxt Drive stands out with its user-friendly interface that allows you to efficiently organize your files into folders, rename them, and quickly filter your documents to find what you need. The platform also offers a powerful command-line tool (Internxt CLI) that gives you the ability to access and manage your data through commands and the WebDAV protocol.
To streamline your digital organization, Internxt enables automatic backup of your computer folders, ensuring you always have the most recent versions of your important files. Document sharing is particularly well-designed: you can choose exactly who to share your files with and even limit the number of allowed downloads.
Unlike many cloud services, Internxt's business model isn't based on exploiting your data or advertising, but on trust. Furthermore, its source code is entirely public on GitHub, allowing anyone to examine, audit, and verify it. This complete transparency enhances the service's credibility and reassures privacy-conscious users.
Internxt is also committed to environmental sustainability through its "green cloud computing" approach. Their data centers are powered by 92% renewable energy, contributing to their goal of achieving climate neutrality by 2050.

Internxt positions itself as the first cloud storage service to implement post-quantum cryptography, marking a significant advancement in data security. This revolutionary technology safeguards your information against future threats posed by quantum computers, which theoretically could break traditional encryption methods.
Specifically, Internxt has integrated the Kyber-512 algorithm, selected by the National Institute of Standards and Technology (NIST). This protection level aims to provide security equivalent to AES-128, the security standard used by other cloud providers. However, the fundamental difference lies in its resistance to potential quantum computer attacks.
Additionally, Internxt follows a "zero-knowledge" policy, meaning that even the company cannot access your data. Your files are encrypted on your device before upload, then fragmented and distributed across different servers. This architecture significantly enhances security since no server ever contains a complete file, only an encrypted fragment that only you can decrypt.
As a Spanish company, Internxt stores all data within the European Union and strictly complies with the General Data Protection Regulation (GDPR). This compliance provides additional protection for European businesses and individuals concerned about their information privacy.
Free Internxt Offer
Internxt generously offers up to 10GB of free storage. However, you initially receive only 1GB upon registration. To unlock additional space, you need to complete several simple actions:
Share a file (additional 1GB)
Subscribe to the company newsletter (1GB)
Install the sync client (1GB)
Invite friends to join the service (up to 7GB)
Internxt's free plan provides access to all essential platform features. Users benefit from post-quantum encryption and zero-knowledge architecture, ensuring optimal security for their stored data.
Among the additional security features, Internxt implements two-factor authentication (2FA), adding an extra layer of protection to your account. A recovery key is also provided, enabling you to regain access to your data if you forget your password.
If the free plan doesn't meet your storage needs, Internxt offers paid plans with expanded storage capacity (ranging from 20GB to 2TB) at competitive rates. For those seeking long-term solutions, lifetime plans are available with up to 10TB of storage space for a one-time payment, backed by a 30-day money-back guarantee.
NordLocker
A subsidiary of Nord Security, NordLocker has established a strong reputation in the field of free online storage through its privacy-focused approach. This service stands out for its advanced encryption system that protects your data against all forms of intrusion, making it an ideal solution for users particularly concerned about their digital privacy.
NordLocker Features
NordLocker offers an intuitive user experience with essential features for secure file management. The service supports all file types, regardless of their size or format. Thanks to automatic synchronization, your documents stay up-to-date across all your devices, allowing you to access your important data wherever you are.
Secure sharing is one of NordLocker's major strengths. You can share files in two different ways: either by granting direct access to another user or by generating a secure link. In both cases, the process benefits from end-to-end encryption, ensuring that no one can intercept your data during transfer.
Furthermore, NordLocker provides a local encryption feature that allows you to protect your files directly on your device without necessarily sending them to the cloud. This option proves particularly useful if you share your computer with others and wish to keep certain documents confidential.
Automatic cloud backup is another valuable function. Once activated in the settings, each new file on your device will be automatically transferred to a secure "locker." This system greatly facilitates data recovery in case of device loss or theft.
To enhance account security, NordLocker offers multi-factor authentication (MFA) directly integrated into the application. This additional protection supports various authentication methods, including authentication apps, third-party security keys, and one-time backup codes.
NordLocker Client-Side Encryption
The core of NordLocker's offering lies in its zero-knowledge architecture. In practical terms, this means that even the NordLocker team cannot access your data. Your files are encrypted locally on your device before being sent to the servers, using a key derived from your master password. This approach ensures complete privacy and security for all your stored data, making NordLocker a trusted choice for users who prioritize data protection.
NordLocker employs a combination of the market's most robust encryption algorithms: AES-256 for managing files and their names, xChaCha20-Poly1305 for protecting keychain and identity data, and Ed25519 for securing your digital signatures. This multi-layered approach maximizes the security and confidentiality of your files.
Beyond end-to-end encryption, NordLocker implements a dual-lock system to protect your account. Users must first log in with their Nord Account credentials, followed by entering their NordLocker master password. This double protection significantly reduces the risk of unauthorized access to your sensitive data.
Nord Security's confidence in their encryption system is so strong that in 2022, the company offered over €9,500 to anyone who could breach an encrypted "locker" made available for download. Despite more than 700 downloads over 350 days, no one managed to compromise the system.
Free NordLocker Storage
NordLocker's free plan provides access to 3GB of storage space. While this capacity is less than some competitors like pCloud (10GB) or MEGA (20GB), it remains adequate for storing important documents or sensitive files.
With this free plan, you get access to several essential features:
Unlimited end-to-end encryption for all your files
Unlimited local encryption on your device
Simple and intuitive interface
Email customer support
However, it's important to note certain limitations: file access is restricted to a single device, file management capabilities are basic, and group sharing is not available. Additionally, free users don't have access to live chat support, only email support.
If your needs evolve, NordLocker offers premium plans starting at $2.99 per month for 500GB of storage. These plans include additional features such as secure file sharing, 24/7 customer support, and multi-device access. A 30-day "satisfaction or money-back" guarantee allows you to try these plans risk-free.
Google Drive
With over 3 billion users, Google Drive stands as the world's most widely used free online storage service. This popularity is largely attributed to its seamless integration with the Google ecosystem and its pre-installed presence on most Android devices.
Google Drive Features
Google Drive offers a unified experience for managing, viewing, and organizing your files. The tool enables real-time editing of Google documents (Docs, Sheets, Slides), Microsoft Office files, and PDFs. The PDF commenting feature proves particularly useful for collaboration.
Google's powerful search capabilities are integrated into Drive, delivering quick and relevant results through artificial intelligence. The platform also allows you to scan and store receipts, bank statements, and other documents as indexed PDFs directly from the mobile application.
Moreover, integration with third-party applications like Slack, Zoom, Salesforce, and Atlassian optimizes your workflow. Drive naturally integrates with Gmail, making it easy to save and organize attachments without leaving your inbox.
Google Drive Security and Privacy
Google implements multiple security measures to protect your data. All files are encrypted during transmission and storage. Each file uploaded to Drive is securely stored in state-of-the-art data centers.
However, unlike other services such as Drime, Google maintains control over both the content and encryption keys, which technically enables them to decrypt your data. The service can scan your documents to enhance its products and target advertising, while also reserving the right to share your information with law enforcement authorities when necessary.
To enhance security, Google Drive offers two-factor authentication and customizable access controls for your shared files. By default, all files remain private and inaccessible to other users unless you choose to share them.
Google Drive Free Storage
Google provides 15 GB of free storage space, shared across Drive, Gmail, and Google Photos. Since June 1, 2021, new files created with Docs, Sheets, Slides, or Forms count toward this quota, while existing documents remain exempt if they haven't been modified after this date.
However, certain items don't impact your storage space, including files in the "Shared with me" section and shared Drives, as well as Google Sites files.
When your storage becomes insufficient, several restrictions apply:
Unable to send or receive emails in Gmail
Cannot sync or upload new files to Drive
Cannot create new files in Google applications
No one can modify or copy your files
If you exceed your quota for two years or more, Google reserves the right to delete all your content after multiple warnings. To increase your capacity, you can subscribe to Google One, with options ranging from 100 GB to 30 TB.

Two-way synchronization ensures that any file modification is automatically reflected in the cloud. Furthermore, Icedrive maintains version history and deleted files without time limitations, making it simple to restore documents to their previous states.
Icedrive Security and Encryption
Icedrive's distinguishing feature lies in its use of the Twofish algorithm rather than standard AES, which the platform considers more secure. For paid accounts, the service offers an "Encrypted" folder where all elements are client-side encrypted, including file and folder names. This means even Icedrive cannot access your data, as the decryption key remains under your exclusive control.
However, it's worth noting that the servers are located in the United Kingdom, a region that has implemented various digital surveillance laws, although the service strictly adheres to GDPR compliance.
Icedrive Free Plan
The Icedrive free plan offers 10 GB of permanent storage space, with no special conditions beyond creating an account. While free users don't have access to client-side encryption or advanced link sharing options, all essential features remain available, allowing users to effectively evaluate the service before considering a paid subscription.

Post-quantum Security Internxt
Internxt positions itself as the first cloud storage service to implement post-quantum cryptography, marking a significant advancement in data security. This revolutionary technology safeguards your information against future threats posed by quantum computers, which theoretically could break traditional encryption methods.
Specifically, Internxt has integrated the Kyber-512 algorithm, selected by the National Institute of Standards and Technology (NIST). This protection level aims to provide security equivalent to AES-128, the security standard used by other cloud providers. However, the fundamental difference lies in its resistance to potential quantum computer attacks.
Additionally, Internxt follows a "zero-knowledge" policy, meaning that even the company cannot access your data. Your files are encrypted on your device before upload, then fragmented and distributed across different servers. This architecture significantly enhances security since no server ever contains a complete file, only an encrypted fragment that only you can decrypt.
As a Spanish company, Internxt stores all data within the European Union and strictly complies with the General Data Protection Regulation (GDPR). This compliance provides additional protection for European businesses and individuals concerned about their information privacy.
Free Internxt Offer
Internxt generously offers up to 10GB of free storage. However, you initially receive only 1GB upon registration. To unlock additional space, you need to complete several simple actions:
Share a file (additional 1GB)
Subscribe to the company newsletter (1GB)
Install the sync client (1GB)
Invite friends to join the service (up to 7GB)
Internxt's free plan provides access to all essential platform features. Users benefit from post-quantum encryption and zero-knowledge architecture, ensuring optimal security for their stored data.
Among the additional security features, Internxt implements two-factor authentication (2FA), adding an extra layer of protection to your account. A recovery key is also provided, enabling you to regain access to your data if you forget your password.
If the free plan doesn't meet your storage needs, Internxt offers paid plans with expanded storage capacity (ranging from 20GB to 2TB) at competitive rates. For those seeking long-term solutions, lifetime plans are available with up to 10TB of storage space for a one-time payment, backed by a 30-day money-back guarantee.
NordLocker
A subsidiary of Nord Security, NordLocker has established a strong reputation in the field of free online storage through its privacy-focused approach. This service stands out for its advanced encryption system that protects your data against all forms of intrusion, making it an ideal solution for users particularly concerned about their digital privacy.
NordLocker Features
NordLocker offers an intuitive user experience with essential features for secure file management. The service supports all file types, regardless of their size or format. Thanks to automatic synchronization, your documents stay up-to-date across all your devices, allowing you to access your important data wherever you are.
Secure sharing is one of NordLocker's major strengths. You can share files in two different ways: either by granting direct access to another user or by generating a secure link. In both cases, the process benefits from end-to-end encryption, ensuring that no one can intercept your data during transfer.
Furthermore, NordLocker provides a local encryption feature that allows you to protect your files directly on your device without necessarily sending them to the cloud. This option proves particularly useful if you share your computer with others and wish to keep certain documents confidential.
Automatic cloud backup is another valuable function. Once activated in the settings, each new file on your device will be automatically transferred to a secure "locker." This system greatly facilitates data recovery in case of device loss or theft.
To enhance account security, NordLocker offers multi-factor authentication (MFA) directly integrated into the application. This additional protection supports various authentication methods, including authentication apps, third-party security keys, and one-time backup codes.
NordLocker Client-Side Encryption
The core of NordLocker's offering lies in its zero-knowledge architecture. In practical terms, this means that even the NordLocker team cannot access your data. Your files are encrypted locally on your device before being sent to the servers, using a key derived from your master password. This approach ensures complete privacy and security for all your stored data, making NordLocker a trusted choice for users who prioritize data protection.
NordLocker employs a combination of the market's most robust encryption algorithms: AES-256 for managing files and their names, xChaCha20-Poly1305 for protecting keychain and identity data, and Ed25519 for securing your digital signatures. This multi-layered approach maximizes the security and confidentiality of your files.
Beyond end-to-end encryption, NordLocker implements a dual-lock system to protect your account. Users must first log in with their Nord Account credentials, followed by entering their NordLocker master password. This double protection significantly reduces the risk of unauthorized access to your sensitive data.
Nord Security's confidence in their encryption system is so strong that in 2022, the company offered over €9,500 to anyone who could breach an encrypted "locker" made available for download. Despite more than 700 downloads over 350 days, no one managed to compromise the system.
Free NordLocker Storage
NordLocker's free plan provides access to 3GB of storage space. While this capacity is less than some competitors like pCloud (10GB) or MEGA (20GB), it remains adequate for storing important documents or sensitive files.
With this free plan, you get access to several essential features:
Unlimited end-to-end encryption for all your files
Unlimited local encryption on your device
Simple and intuitive interface
Email customer support
However, it's important to note certain limitations: file access is restricted to a single device, file management capabilities are basic, and group sharing is not available. Additionally, free users don't have access to live chat support, only email support.
If your needs evolve, NordLocker offers premium plans starting at $2.99 per month for 500GB of storage. These plans include additional features such as secure file sharing, 24/7 customer support, and multi-device access. A 30-day "satisfaction or money-back" guarantee allows you to try these plans risk-free.
Google Drive
With over 3 billion users, Google Drive stands as the world's most widely used free online storage service. This popularity is largely attributed to its seamless integration with the Google ecosystem and its pre-installed presence on most Android devices.
Google Drive Features
Google Drive offers a unified experience for managing, viewing, and organizing your files. The tool enables real-time editing of Google documents (Docs, Sheets, Slides), Microsoft Office files, and PDFs. The PDF commenting feature proves particularly useful for collaboration.
Google's powerful search capabilities are integrated into Drive, delivering quick and relevant results through artificial intelligence. The platform also allows you to scan and store receipts, bank statements, and other documents as indexed PDFs directly from the mobile application.
Moreover, integration with third-party applications like Slack, Zoom, Salesforce, and Atlassian optimizes your workflow. Drive naturally integrates with Gmail, making it easy to save and organize attachments without leaving your inbox.
Google Drive Security and Privacy
Google implements multiple security measures to protect your data. All files are encrypted during transmission and storage. Each file uploaded to Drive is securely stored in state-of-the-art data centers.
However, unlike other services such as Drime, Google maintains control over both the content and encryption keys, which technically enables them to decrypt your data. The service can scan your documents to enhance its products and target advertising, while also reserving the right to share your information with law enforcement authorities when necessary.
To enhance security, Google Drive offers two-factor authentication and customizable access controls for your shared files. By default, all files remain private and inaccessible to other users unless you choose to share them.
Google Drive Free Storage
Google provides 15 GB of free storage space, shared across Drive, Gmail, and Google Photos. Since June 1, 2021, new files created with Docs, Sheets, Slides, or Forms count toward this quota, while existing documents remain exempt if they haven't been modified after this date.
However, certain items don't impact your storage space, including files in the "Shared with me" section and shared Drives, as well as Google Sites files.
When your storage becomes insufficient, several restrictions apply:
Unable to send or receive emails in Gmail
Cannot sync or upload new files to Drive
Cannot create new files in Google applications
No one can modify or copy your files
If you exceed your quota for two years or more, Google reserves the right to delete all your content after multiple warnings. To increase your capacity, you can subscribe to Google One, with options ranging from 100 GB to 30 TB.
MEGA
Known for its generosity, MEGA has established itself as one of the most attractive free online storage services in 2025. With over 300 million registered users, this platform founded by Kim Dotcom offers a privacy-focused approach that particularly appeals to users concerned about their digital privacy.
MEGA Features
MEGA offers a comprehensive ecosystem integrating storage, sharing, and communication within a single interface. Its transfer manager, available in the desktop application, enables extremely high-speed downloads and uploads. The platform stands out for its support of unlimited file sizes, a particularly useful feature for professionals who regularly handle large content.
Real-time automatic synchronization ensures your files stay up-to-date across all your devices. Additionally, MEGA expanded its offering in 2024 with the integration of an encrypted password manager (MEGA Pass) and a VPN service included in all paid subscriptions.
File sharing benefits from a flexible approach. You can share direct links or entire folders with other MEGA users, precisely defining access permissions. Furthermore, MEGA offers a secure messaging function allowing users to chat and share files directly from the application.
MEGA Encryption and Security
Security forms the cornerstone of MEGA's infrastructure. The platform implements zero-knowledge encryption, meaning that you alone possess the keys to decrypt your data. This end-to-end encryption occurs directly on your device before files are transferred to the servers.
In practice, all your files are encrypted using keys generated from your master password. Each item has a unique decryption key, thereby strengthening the overall system security. For additional protection, MEGA offers two-factor authentication (2FA) through an authentication app.
The platform also provides protection against ransomware attacks through its robust versioning system. In case of infection, you can recover previous versions of your files that haven't been encrypted by the malicious software.
MEGA Free Storage Volume
MEGA generously offers 20 GB of permanent storage space in its free plan, positioning the platform among the most generous in the market. This volume can be significantly increased through the achievement program:
Installing MEGAsync (desktop application): Additional 5 GB
Installing the mobile application: Additional 5 GB
Phone number verification: Additional 5 GB
Referring friends: 5 GB per invited friend
These bonuses, totaling up to 15 GB additional storage, remain valid for 365 days. However, note that free accounts are subject to transfer quotas, typically reset every 24 hours. These limits are determined by your IP address but can be bypassed using a VPN.
If you need more space, MEGA offers several paid plans up to 16 TB, as well as flexible options where you only pay for the additional space used.
Icedrive
Launched in 2019, Icedrive has quickly established itself as an innovative player in the free online storage space thanks to its clean interface and strong focus on data privacy. While relatively new compared to solutions like Drime which offers a complete suite of collaborative tools, this British service has managed to differentiate itself through its unique approach to cloud storage.
Icedrive Features
Icedrive offers a modern and intuitive interface that makes it easy to manage all types of files without size restrictions. The desktop application creates a virtual drive directly accessible from Windows Explorer, functioning like an external hard drive without taking up space on your computer. Additionally, the online preview feature for numerous formats (documents, images, videos) eliminates unnecessary downloads, even including a mini-player for enjoying audio files on smartphones.
Two-way synchronization ensures that any file modification is automatically reflected in the cloud. Furthermore, Icedrive maintains version history and deleted files without time limitations, making it simple to restore documents to their previous states.
Icedrive Security and Encryption
Icedrive's distinguishing feature lies in its use of the Twofish algorithm rather than standard AES, which the platform considers more secure. For paid accounts, the service offers an "Encrypted" folder where all elements are client-side encrypted, including file and folder names. This means even Icedrive cannot access your data, as the decryption key remains under your exclusive control.
However, it's worth noting that the servers are located in the United Kingdom, a region that has implemented various digital surveillance laws, although the service strictly adheres to GDPR compliance.
Icedrive Free Plan
The Icedrive free plan offers 10 GB of permanent storage space, with no special conditions beyond creating an account. While free users don't have access to client-side encryption or advanced link sharing options, all essential features remain available, allowing users to effectively evaluate the service before considering a paid subscription.
