FlowCrypt encrypts Gmail messages with PGP, but that protection ends the moment a recipient decrypts a file. PPAD keeps files encrypted, trackable, and revocable long after they leave your inbox, and recipients never touch a password.
PPAD is built on Digify's ISO27001 certified practices, with SOC 2 compliance packages available on Enterprise. Files are encrypted with AES-256 through a patent-pending layered architecture that keeps working after download. Processing is GDPR-aligned, with data residency, SSO and on-premises deployment on Enterprise. FlowCrypt's own security and HIPAA pages cite Cure53 audits instead, not ISO 27001 or SOC 2, and state the company isn't HIPAA certified.

PPAD is the strongest alternative for teams that need protection to survive past the inbox. FlowCrypt secures a message in transit with PGP, but once a recipient decrypts it the file is fully exposed. PPAD keeps encryption, tracking, and revocation active on the file itself, whether it lives in Gmail, Google Drive, or a shared link.
PPAD and FlowCrypt solve different problems. FlowCrypt is a PGP encryption layer for Gmail messages, with no revocation or analytics once a recipient decrypts. PPAD is built for teams that need to know what happens to a file after it leaves their control: who opened it, when, and the ability to shut off access at any time, even after download.
FlowCrypt's core email encryption is free for organizations with fewer than 100 users, according to their own documentation. Larger deployments require the Enterprise Server, priced only after contacting sales through their request form. Their separate Workspace Key Manager product does list per-seat annual pricing, starting at €799 a year for 10 seats. PPAD publishes its Email plan at $25 per user per month on ppad.io/pricing.
Yes, switching from FlowCrypt to PPAD does not require new infrastructure. PPAD installs as a Gmail plugin with a single toggle to encrypt outgoing messages and attachments, plus a Google Drive extension for files already stored there. Recipients open protected files without a PGP key exchange or a password you have to send separately.
No, FlowCrypt's protection ends once a recipient enters the password and decrypts the message. Their own documentation describes decryption as a one-time action, with no mechanism to revoke access, change permissions, or set a new expiry afterward. PPAD keeps working after download: access can be revoked, permissions changed, and expiry adjusted at any time, even on files a recipient already opened.
Yes. PPAD is built on Digify's ISO/IEC 27001:2022 certified practices, is SOC 2 compliant, and encrypts files with AES-256 through a patent-pending layered architecture. Processing is GDPR aligned.
Not yet, for most teams. FlowCrypt's browser extension covers Gmail on Chrome and Firefox only, though its Android app also supports Outlook, Exchange and generic IMAP or SMTP accounts, while the iOS app works with Gmail alone. PPAD is live in Gmail and Google Drive today, with Microsoft 365 Outlook and SharePoint support publicly marked as coming soon, so neither product is Microsoft-first yet.
No, with FlowCrypt, recipients without the extension read a password-protected message through a web portal, but the sender has to share that password through a separate channel first. PPAD recipients open a file in the browser, install the lightweight PPAD Viewer extension, or verify with a one-time email passcode, and never handle a password at all.
No, not in the standard sense. FlowCrypt publishes its browser extension source on GitHub, but under a custom FlowCrypt License with production and usage restrictions, not a standard open-source or permissive license. That still gives outside researchers more code to inspect than PPAD publishes, though PPAD backs its claims with ISO/IEC 27001:2022 certification and SOC 2 compliance packages that FlowCrypt's own pages do not list.
Switch from FlowCrypt to PPAD and keep control over every file you send, long after it leaves your inbox. Start on the free plan, where recipients need no desktop software, and upgrade whenever you need more.
