1. Internxt – Secure Cloud Storage with VPN -------------------------------------------

Internxt offers a secure, open-source platform for cloud storage, file sharing, and collaboration, tailored for both individuals and businesses. Internxt Drive facilitates the uploading, syncing, and backing up of files with robust encryption and security measures.

Unlike services like Google Drive, Internxt encrypts data on your device before it's sent over the internet. This end-to-end encryption safeguards your files from unauthorized access and ensures complete privacy for your sensitive data.

Additionally, Internxt supports secure file sharing, enabling safe exchanges with friends, family, or within teams and departments under business plans.

Internxt's security features include password-protected files, automatic backups, Two-Factor Authentication, and the ability to set expiration dates for shared folders, providing top-tier privacy and security to prevent data loss.

2. Signal – Secure Text Messaging and Video Conferencing

Signal is an open-source messaging app that enables free text and voice messaging, photo, video, GIF, and file sharing. Though not as widely recognized as Telegram or WhatsApp, it's favored by advanced users for its strong emphasis on data privacy.

Its robust security features make it nearly impossible for communications to be intercepted, unlike with other messaging platforms.

Signal employs the Signal Protocol, an end-to-end encryption method developed by Open Whispers Systems, ensuring messages are encrypted on your device and only decrypted upon reaching the recipient's device.

This encryption is applied by default to all messages and calls, unlike Telegram, which only encrypts private chats. Signal also offers a self-destruct feature for messages, settable from 5 seconds to a week, enhancing conversation security.

Signal's open-source nature allows for transparent scrutiny of its code on Github, making it a trusted choice for privacy-conscious users.

Install Signal in Linux

The following steps are for installing Signal on 64-bit Debian-based Linux distributions like Ubuntu and Linux Mint.

<code>$ wget -O- https://updates.signal.org/desktop/apt/keys.asc | gpg --dearmor > signal-desktop-keyring.gpg
$ cat signal-desktop-keyring.gpg | sudo tee -a /usr/share/keyrings/signal-desktop-keyring.gpg > /dev/null
$ echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/signal-desktop-keyring.gpg] https://updates.signal.org/desktop/apt xenial main' |\ sudo tee -a /etc/apt/sources.list.d/signal-xenial.list
$ sudo apt update && sudo apt install signal-desktop</code>

3. Nextcloud – Secure File Sharing

Nextcloud is an open-source platform that allows you to set up a personal server for file sharing and synchronization across various devices and users.

It offers functionalities similar to Google Drive, and extends to features akin to Google Calendar and Google Photos.

The Nextcloud App Store provides numerous applications to enhance your platform, including blogs, maps, multimedia players, SMS synchronizers, office suites, Markdown editors, video conferencing, task managers, notes, password managers, RSS readers, and more.

Nextcloud encrypts files during transit and offers local storage encryption, ensuring that even administrators cannot access user data.

4. Tor Browser – Secure Internet Surfing

For those interested in anonymous and secure internet browsing, the Tor Project is renowned. Tor, or The Onion Router, uses a layered network to enhance privacy and anonymity.

It creates a decentralized network across multiple nodes, making it difficult to trace your internet activity.

The Tor Browser allows easy connection to the Tor network without complex configurations, available for Linux, Windows, macOS, and Android.

It functions similarly to other browsers but isolates each web page to prevent tracking and automatically clears cookies and browsing history upon logout.

When using Tor Browser, your traffic is encrypted three times over the Tor network, ensuring your online activities remain private.

5. Tutanota – Secure Email Messaging

Tutanota, a German web-based email service, focuses on security and privacy with the slogan “Secure email for everyone!”. It features end-to-end encryption, identity protection, and secure communication with users of other email services like Gmail or Outlook.

Upon registration, Tutanota provides a custom email address. It offers various pricing plans starting at $0 per month, with free accounts having limited features and storage.

Tutanota implements multiple encryption methods, including end-to-end encryption between Tutanota users and optional password-protected encryption for emails sent to other services.

While primarily a web app, Tutanota also offers open-source apps for Android, iOS, and desktop clients for Linux, Windows, and macOS.

6. ONLYOFFICE Workspace – Secure Document Collaboration

ONLYOFFICE Workspace is an open-source suite that includes collaborative editors for documents, spreadsheets, and presentations, along with various web apps for document management, projects, CRM, email, calendaring, real-time communication, and social networking.

ONLYOFFICE Workspace uses HTTPS and JSON Web Token for data protection, offering features like two-factor authentication, SSO, and automatic and manual backups.

End-to-end encryption is facilitated through the Private Rooms feature in the Documents module, where documents are encrypted with the AES-256 algorithm. Changes made in these rooms are encrypted locally, transferred securely to the server, and decrypted upon receipt.

Private Rooms are accessible via ONLYOFFICE Desktop Editors, requiring only a connection to your ONLYOFFICE Workspace instance to start editing securely without the need for manual password entry.

Conclusion

Remember, data encryption is merely a tool to help you maintain online safety. It does not ensure complete privacy without adhering to basic security practices, such as securing access to your devices and networks, and using tools like password managers and backup applications.

When used correctly alongside other security measures, data encryption significantly enhances your online security.
