What is FlowCrypt
FlowCrypt is an email encryption product that adds OpenPGP (PGP) encryption and digital signing to common email workflows, primarily through browser extensions and web integrations. It targets individuals and teams that need end-to-end encrypted email while continuing to use existing mail providers (for example, webmail and hosted email). FlowCrypt emphasizes client-side key management and message encryption/decryption in the user’s environment rather than routing mail through a separate encrypted mailbox service. It is commonly used for encrypting sensitive email content and attachments and for exchanging encrypted messages with external recipients.
OpenPGP-based end-to-end encryption
FlowCrypt uses the OpenPGP standard, which supports interoperable encryption and signing with other PGP tools. This makes it suitable for organizations that need standards-based encrypted email rather than a closed ecosystem. It also supports signing to help recipients verify message integrity and sender identity. The approach fits workflows where users must keep their existing email addresses and providers.
Works with existing email providers
FlowCrypt is designed to layer encryption onto existing email services instead of requiring a separate mailbox platform. This can reduce disruption for teams that already use webmail and established identity and access controls. It is particularly relevant for encrypting messages to external parties without migrating domains. Deployment can be as simple as enabling extensions or managed configurations for supported environments.
Client-side key control options
FlowCrypt focuses on encrypting and decrypting content on the client side, aligning with end-to-end encryption expectations. It supports user key generation/import and typical PGP key lifecycle tasks (such as using public keys for recipients). For organizations, this can help keep private keys under user or enterprise control rather than stored by a mail security gateway. This model can be advantageous when compliance requirements favor user-held keys.
PGP usability and key management
PGP-based email encryption introduces operational overhead, including key distribution, verification, rotation, and recovery. Users often need training to avoid common mistakes (wrong recipient key, missing public keys, or sending unencrypted replies). Compared with some email security suites, FlowCrypt’s value depends heavily on correct user behavior and key hygiene. These factors can slow adoption in less technical teams.
Limited gateway-style security controls
FlowCrypt primarily addresses encryption and signing, not the full range of inbound/outbound email security controls. Organizations that need integrated anti-phishing, malware scanning, URL rewriting, quarantine workflows, or broad policy enforcement may require additional tooling. This can increase complexity when compared to consolidated email security platforms. It is better positioned as an encryption layer than as a complete email security stack.
Feature coverage varies by client
Capabilities and user experience can vary depending on the supported email client and deployment method (for example, browser extension vs. other integrations). Some enterprise requirements—such as centralized auditing, eDiscovery alignment, or advanced administrative reporting—may be less comprehensive than products built as full enterprise email platforms. Compatibility constraints can also affect mixed environments. Buyers typically need to validate supported clients and admin features for their specific setup.
