Send Sensitive Files Securely: DLP, Watermark, and Encryption

Why Secure File Transfer Matters

In today’s digital workplace, sending sensitive files—financial records, legal documents, or healthcare data—requires more than just email. Breaches and accidental leaks are expensive and can damage a reputation. Secure file transfer ensures that your data is encrypted, monitored, and controlled throughout its lifecycle.

Businesses need to combine multiple layers of protection, including DLP solutions, file encryption, and document watermarking, to mitigate risk. This approach safeguards sensitive information while maintaining compliance with privacy regulations.

Understanding DLP, Watermarking, and Encryption

Data Loss Prevention (DLP)

DLP solutions help organizations detect, monitor, and prevent unauthorized sharing of sensitive files. DLP can flag sensitive content before it leaves your network, ensuring compliance with regulatory requirements such as HIPAA, GDPR, or corporate security policies.

Document Watermarking

Watermarking adds visible or invisible identifiers to documents. It deters unauthorized sharing and provides traceability if a file is leaked. When combined with file encryption, watermarking enhances accountability while protecting sensitive information.

Encryption

File encryption is the backbone of secure data transfer. Encrypted files are unreadable without the correct key, ensuring that even if intercepted, the content remains protected. For businesses handling sensitive client information, an encrypted transfer is essential for both security and compliance.
