About Zivver

Zivver is an email security platform that integrates with existing email clients like Microsoft 365 and Google Workspace to provide enhanced protection for sensitive communications. The platform focuses on securing email content and attachments through encryption and data loss prevention capabilities. Built primarily for organizations handling sensitive data, Zivver adds security layers on top of standard email infrastructure without requiring recipients to create accounts or install software.

What does Zivver do?

The platform employs multiple security approaches to protect email communications. At its core, Zivver uses zero-access encryption, meaning neither Zivver nor third parties can access encrypted message content - only senders and intended recipients hold decryption keys. The system analyzes email content and attachments in real-time using machine learning to identify sensitive information and potential security risks before messages are sent. When risks are detected, it can enforce security measures like multi-factor authentication for message access.

Beyond encryption, Zivver provides data loss prevention capabilities designed to prevent common causes of breaches. The platform includes features to catch potential errors like incorrect recipients, accidental BCC exposure, and unintended sharing of sensitive data in spreadsheet tabs. For large file transfers, Zivver allows secure sharing of files up to 5TB directly through email rather than requiring separate file transfer services.

What makes Zivver different?

A key technical differentiator is Zivver's implementation of zero-access encryption architecture. While many email security tools rely on transport layer security (TLS) encryption alone, Zivver adds additional encryption layers that remain active after delivery. The platform maintains security even when recipient systems don't support TLS, addressing a common vulnerability where emails default to unencrypted delivery when security protocols don't match.

The platform's integration approach also sets it apart. Rather than requiring users to adopt new workflows or recipients to create accounts, Zivver embeds into existing email clients. Recipients can access secure messages through a web interface using multi-factor authentication methods like SMS codes or time-based passwords. This maintains security without creating significant friction in communication processes.

Use cases and industries

Zivver targets industries handling sensitive data subject to regulatory requirements. Healthcare organizations use it to securely share patient information while maintaining HIPAA compliance. Legal firms rely on it to protect client communications and confidential case documents. Government agencies and financial institutions implement it to secure communications containing personal data subject to GDPR and other privacy regulations.

The platform addresses specific industry compliance needs through features like automated logging of email access and delivery status, which supports audit requirements. Advanced encryption capabilities help organizations meet standards like NTA 7516 for healthcare communications. While primarily focused on email security, Zivver's large file transfer capabilities make it relevant for organizations regularly sharing sensitive documents that exceed normal email size limits.
