## What is CloudMask End-to-End Encryption?

CloudMask End-to-End Encryption (E2EE) is a data protection solution designed for the financial services sector, enabling encryption of emails, files, and cloud-hosted application data. The product ensures that only the sender and intended recipient can access plaintext data — cloud providers, third parties, governments, and the vendor itself cannot decrypt user content.

Key operational model:
- Encryption keys are generated and stored exclusively on the user's devices; they are never transmitted or shared with any external party.
- Users activate encryption via a "CloudMask Lock" button within their existing applications, requiring minimal workflow changes.
- The product integrates with existing SaaS applications such as Gmail and Google Drive without requiring application replacement.

Compliance coverage:
- Supports adherence to SOX, GLBA, FTC, CFPB, and GDPR requirements for data privacy and breach notification.

Security scope:
- Addresses threats including compromised credentials, hijacked accounts, cloud provider breaches, insider threats, and government surveillance.

The product has achieved Common Criteria certification, recognized by 26 cybersecurity agencies worldwide. It is marketed toward financial services organizations but also serves legal, healthcare, and education sectors. CloudMask reports over 100,000 users protected. The solution is available as a free trial with paid subscription plans.
