CloudMask End-to-End Encryption for Healthcare is an encryption solution designed to protect sensitive healthcare data — including PII and ePHI — in emails, files, and cloud applications. The product operates by generating encryption keys that reside solely on the user's devices. These keys are never transmitted or shared, meaning that only authorized senders and recipients can decrypt data. Even cloud providers, third-party services, and CloudMask itself cannot access the protected content. CloudMask integrates with existing applications without requiring users to change their workflows. Users activate encryption by clicking a "CloudMask Lock" interface element within their current apps. The solution supports on-premises and cloud-hosted applications. The product is oriented toward healthcare compliance requirements, including HIPAA, CMS, ASTM, and ICH standards, and is intended to reduce liability related to data breaches and data privacy regulations. CloudMask's end-to-end encryption implementation has received Common Criteria certification, recognized by 26 cybersecurity agencies worldwide. The solution targets healthcare organizations that need to protect communications and stored data shared among physicians, technicians, and patients.
