To guarantee secure file sharing with remote external partners, I implement strong encryption protocols like TLS for data in transit and ensure files are encrypted at rest. I use secure platforms that support multi-factor authentication (MFA) and enforce access control policies, ensuring only authorized personnel can view or edit files. Regularly auditing file access logs helps identify suspicious activities. I also provide security awareness training to partners on secure sharing practices. Lastly, data loss prevention (DLP) tools are employed to detect and prevent unauthorized sharing or leaks.

- Use a secure file-sharing service like a dedicated SFTP server, SharePoint, OneDrive, Google Drive, or Box, which encrypts data both in transit and at rest. - Ensure end-to-end encryption is enabled. Limit file access based on roles and permissions, applying least privilege and setting expiration dates to avoid prolonged access. -Enforce multi-factor authentication (MFA) for all users, adding security beyond passwords. - Monitor file access through audit logs to detect unauthorized attempts. - Implement data loss prevention (DLP) policies to prevent accidental or malicious sharing of sensitive information and ensure compliance with regulations.

To ensure secure file sharing with external partners, use encrypted file transfer protocols such as SFTP or secure cloud storage services that offer end-to-end encryption. Implement access controls, granting only necessary permissions based on the principle of least privilege. Use secure password management solutions to share credentials safely. Establish a shared workspace with audit logs to track access and changes. Additionally, require multi-factor authentication for both your team and external partners. Regularly review and update security policies to address emerging threats and ensure compliance with relevant regulations.

✔Use Encrypted Platforms: Choose services with end-to-end encryption. ✔Access Controls: Limit file access with role-based permissions. ✔Regular Audits: Monitor access logs and conduct security audits. ✔Data Classification: Apply security measures based on data sensitivity. ✔Secure Password Practices: Use strong, unique passwords and update regularly.

In addition to the obvious requirement for TLS/MFA, you should really share sensitive files using your own infrastructure (sftp is generally an easy and good way). You never know what could happen without you knowing with public services like onedrive, dropbox, etc.
