Echoworx

Echoworx is a cloud-based email and message encryption company that has operated for over two decades. The company provides encryption solutions designed to protect sensitive data transmitted via email, mobile, and web channels. Its platform is built on a cloud architecture and is designed to integrate into existing enterprise workflows without requiring significant changes to existing infrastructure. Echoworx serves enterprise customers across industries including banking, financial services, and healthcare. Notable use cases include delivering encrypted communications at scale (over 100 million encrypted communications annually for one customer) and migrating large user populations to cloud-based encryption. The platform supports policy-based encryption, meaning encryption rules can be applied automatically based on content detection — such as keywords, attachment types, or sensitive data patterns like credit card numbers — rather than relying on individual users to manually encrypt messages. The company addresses compliance requirements tied to regulations such as NIS2, DORA, CER, and KRITIS-DachG, positioning its platform as a tool for organizations navigating complex regulatory environments. Features relevant to IT and security teams include S/MIME certificate management, SSO integration, and cloud migration support. Echoworx also offers custom-branded secure messaging experiences and supports sovereign data protection use cases. The company has expanded into markets such as Germany in response to strengthening privacy legislation. It maintains integrations with platforms such as Microsoft Office 365 and Google Workspace, as evidenced by a Google Add-On release in 2024.
