Encryptomatic OpenPGP vs OpenText Core Email Message Privacy

Encryptomatic OpenPGP is a Windows application for encrypting and signing messages and files, with Outlook integration. Encryption happens locally on the PC, and messages remain protected end-to-end from sender to recipient; recipients need OpenPGP software to decrypt them. Files can also be encrypted or signed from the Windows right-click context menu. The software supports Windows 10 and 11, plus listed Classic Outlook versions from 2013 through Microsoft 365 in 32-bit or 64-bit editions. PGP key-server support covers key sharing, discovery, and revocation, including MIT.EDU. Administrators can customize the interface and deploy through MSI silent installation and registration; some shared environments can use activation-free enterprise versions. Personal users, nonprofits, activists, and individual journalists can use it free, while for-profit business domains require a license. Business and free editions have identical encryption capabilities. Business pricing starts at $29.99 a year for one license; Mac is not supported.

OpenText Core Email Message Privacy secures sensitive messages and files while allowing senders to control access throughout a message’s lifecycle. Through Outlook or a secure portal, users can send attachments up to 100 GB per message. Digital-rights controls can restrict viewing, replies, forwarding, and expiration, while senders can later adjust or revoke rights. Recipients open secure messages through browser or mobile web links without installing software or a native app. Delivery, opens, downloads, and signatures are tracked in real time for auditability. Messages and files uploaded to the portal are encrypted at rest with AES 256. The service supports legally binding electronic signatures, Outlook and Single Sign-On integrations, and corporate branding. It is delivered as SaaS without additional infrastructure and works with hosted, on-premises, and hybrid email systems. OpenText describes it for managed service providers protecting small and medium-sized businesses. Pricing is on request; there is no free plan, and only professional users consume licenses while guest recipients are free.
