5 Best Ways To Securely Share Your Business Big Files

5 Best Ways for secure file sharing

With cybersecurity threats rising, securing and sharing large, sensitive business files is more crucial than ever. The best methods for secure file sharing leverage encryption, access controls, and file compression to keep data safe.

Top techniques for secure file sharing include using client-side encryption services like Tresorit that keep files encrypted until the recipient decrypts them, deploying remote access tools like Citrix ShareFile that allow granular control over file access, sending files through secure email platforms like Virtru that encrypt attachments, transferring files peer-to-peer with blockchain-powered systems like Filen, and compressing files with Zip formats before sending to reduce transfer times and chances of data corruption.

The most secure services for secure file sharing provide zero-knowledge encryption where only the sender and recipient have the keys without the platform storing them. Some also offer remote wipe capabilities to revoke access if files fall into the wrong hands.

With cyberattacks and data leaks accelerating, lockdown file sharing across devices, email, cloud drives, and networks is essential for protecting IP, financial data, customer information, and other sensitive materials. The best approaches allow businesses to collaborate efficiently while keeping proprietary files under lock and key.

Best Practices for Securing Large Business Files

Best Practices for Securing Large Business Files

Securing large, sensitive business files is crucial to protecting proprietary information, financial data, customer details, and other critical materials. With rising cyber threats, companies must take proactive steps to safeguard files. The following is an extensive note on the best practices for securing large business files:

Use Encryption

Encryption converts data into coded form so only authorized parties can access it. Encrypt files containing sensitive information, both at rest and in transit between systems. This ensures files remain secured if intercepted. Services like Tresorit provide zero-knowledge encryption where only the sender and recipient have the keys.

Control Access 

Implement access controls restricting file availability to only personnel who need it for their role. This follows the principle of least privilege. Tools like Citrix ShareFile allow admins to customize user permissions.

Compress Large Files

Compress Large Files

Big files strain networks and are more prone to corruption. Compressing with Zip formats before transfers reduces size. This cuts transfer times and boosts reliability.

Train Employees 

Human error causes many data breaches. Train staff on your file-sharing system and security policies. Establish proper vs. improper sharing habits. Stress the impact of lapses like exposing customer data.

Support Secure Protocols

Legacy protocols like FTP transmit files unencrypted. Use modern versions like SFTP that leverage SSH encryption and two-factor authentication. Integrate secure transfers with your workflows.  

Audit Access and Activity

Log user file interactions so you can trace incidents. Monitoring for suspicious activity lets you rapidly respond to potential threats. Some systems also notify admins about anomalies.  

Back-Up Sensitive Data

Maintain file backups you can restore if ransomware encrypts your files, ensuring secure file sharing. Keep regular copies both onsite and cloud-based in case of disruption to corporate systems. Test restoration periodically for secure file sharing practices.

The security best practices reduce the risk of mistakes, data leaks, unauthorized access, and malicious attacks that lead to legal, financial, and reputational damages.
