What does email encryption do?

It’s Really Quite Simple

Cloudstar email encryption protects sensitive communications while keeping workflows simple and efficient. The system operates behind the scenes to secure every message, ensuring confidentiality, integrity, and compliance without adding unnecessary steps for users or administrators.

The use of email encryption is an important first step in securing emails against the prying eyes of hackers.

Automatic Policies are Here to Help

At the core of the solution is an intelligent policy engine, designed to detect and secure sensitive emails automatically. By scanning content for specific keywords, patterns, or recipient domains, the system applies appropriate encryption based on organizational rules and regulatory obligations.

This automated approach provides a dependable safety net that aligns with GDPR, HIPAA, GLBA, PCI-DSS, and other global compliance standards. User-level policies can also be tailored for more granular control over individual roles or departments.

Built For the Way You Work

Seamless integration with enterprise platforms like Microsoft 365, Microsoft Exchange, and Google Workspace ensures minimal disruption to existing workflows. As a fully cloud-based service, it deploys quickly and scales effortlessly alongside business growth. Deployment is managed entirely by a dedicated team, allowing organizations to stay focused while implementation is handled end-to-end.
