FlowCrypt vs OpenText Core Email Message Privacy

FlowCrypt is an email encryption service that lets users send encrypted messages to OpenPGP users and password-protected messages to other recipients. Recipients can reply securely without installing a plugin. It is offered as a Chrome extension, with other platforms and a mobile application also listed. Gmail and Outlook integration are listed, along with message expiry and password-based recipient verification. The free plan is for fewer than 100 users and lists a 5 MB attachment threshold, while product details say free users can add attachments up to 25 MB. Enterprise supports domains with more than 100 users, and administrators can set domain-wide controls and enforce rules for passphrases, keys, and signing. Enterprise also supports SSO through Google, OIDC providers, and delegated identity providers, and can connect with public key servers, HSMs, and internal systems. Enterprise commercial-use pricing requires contacting FlowCrypt. Its enterprise data processing agreement is described as GDPR-compliant, and enterprise support includes an SLA for availability and response times for fixes and patches.

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.
