DataMotion Secure Email Exchange
DataMotion Secure Email Exchange enables organizations to send and receive encrypted email and attachments to protect sensitive information in transit and at rest. Recipients can access secure attachments from their inbox through Clickless SafeTLS without a password, portal login, or decryption step. The service integrates with Microsoft Outlook, Microsoft Teams, Google Workspace, and Power Automate; RESTful APIs can connect its secure email functions to EHR, CRM, and ERP systems, applications, and portals. It tracks messages and attachments sent, received, and opened, with audit trails and delivery records. DataMotion says it uses AES encryption and FIPS 140-2 validated cryptography. Its product page lists support for regulations including HIPAA, GLBA, PCI-DSS, HITECH, GDPR, PIPEDA, FINRA, and CJIS, as well as certifications and credentials including HITRUST CSF, DirectTrust/EHNAC, ONC-Health IT Modular Certification, and SOC 2 for cloud services. The platform runs on Microsoft Azure public cloud infrastructure described by DataMotion as FedRAMP-certified. A free plan and free trial access to Secure Message Center are listed; enterprise pricing is on request, and no trial duration is stated.
gpg4o
gpg4o is a Microsoft Outlook add-in for encrypting, decrypting, signing, and checking messages and attachments. It uses public and private keys under the OpenPGP standard, and supports encrypted HTML email, PGP/MIME, and PGP/Inline. Its key management can synchronize keys, use local or public key servers, and check the Web of Trust; central management requires Enterprise KeyServer. The product also supports terminal servers, Microsoft Policy Manager, automatic key generation, and working groups. When encryption is enabled, it protects message text and attachments, but not the subject line or recipient list. The current feature page lists Outlook 2024 or 365 Classic on Windows 11 and marks Mac OS unsupported. A limited free version is available without a time limit, and a 180-day trial is noted. The listed gpg4o plan costs €99.95 a month. After maintenance expires, users can still send and read encrypted or signed email, but they do not receive further updates.
