SendSafely is the encryption layer that lives inside MS Outlook and Gmail. Your team composes email the way they always have — SendSafely silently encrypts the sensitive message body and attachments. Recipients click, verify, and decrypt. No accounts. No recipient signups. No retraining.
Your team already sends sensitive files over email — that's where customers, partners, and vendors want them. Most organizations choose between standard attachments and traditional secure email. Both involve trade-offs when sharing highly sensitive information.
A typical attachment crosses third-party mail servers, is available to anyone with access to the recipient's inbox, can persist indefinitely, and is copied into backup and archive solutions downstream. TLS between hops is not end-to-end encryption. And Outlook and Gmail cap attachment size, so users route around them with consumer file-share links.
Traditional secure email often asks recipients to create an account, remember a password or passphrase, or switch to a separate portal. Every additional step adds friction, slows communication, and reduces adoption. Security only works when people actually use it.
The sender composes email exactly the way they always have. SendSafely handles the encryption between Outlook or Gmail and the recipient's browser — and the recipient never has to sign up for anything.

— Sent encrypted via SendSafely. Click the link to decrypt in your browser.
From Outlook or Gmail, your user writes the email and attaches a file the way they always do. The SendSafely plugin transparently encrypts the file in the browser and swaps the attachment for a secure link before the message is sent.
The recipient gets a normal email with a SendSafely link. They click, verify identity with a one-time code sent to their email or phone, and the file decrypts in their browser. No signup, no client, no shared password.
Files are end-to-end encrypted and our split-key architecture ensures only the intended recipient—not SendSafely or your email provider—can decrypt the contents. Every message open is logged for your audit trail.
Install from the Microsoft 365 admin center or Google Workspace Marketplace. The plugin lives in the compose window — no second inbox, no behaviour change for senders.
An Outlook add-in that lets your team send end-to-end encrypted files and messages with one click — from Outlook desktop, Outlook on the web, and the Microsoft 365 mobile apps.
A Chrome extension that integrates SendSafely directly into the Gmail compose window. Encrypt the whole message body or just attachments — without leaving Gmail or copying links between tabs.
For organizations that need enterprise-wide coverage and automated protection, the Serverless Email Gateway runs inside your own AWS account and encrypts email automatically based on policy rules you define.
A policy-based encryption gateway powered by AWS Lambda that automatically protects email before it reaches any recipient. Configure rules to encrypt attachments, message bodies, or both — every sender on every device is covered from a single deployment.
Security, IT, and compliance get the controls they need. Senders keep their workflow. Recipients keep their inbox. Everyone uses email the way they already do.
External recipients click the link, verify identity, and decrypt in any modern browser. No signup, no client install, no pre-shared keys, no passwords forwarded in a second email.
Both the file and the message text are encrypted before they leave the sender's device. All encrypted content sent via SendSafely can be configured to automatically expire and be deleted on your prescribed schedule.
Outlook and Gmail cap attachments at 25 MB. SendSafely handles files up to 100 GB with chunked, resumable uploads — so teams stop routing around encryption with consumer file-share links just to move a large file.
Who opened it, when, from where, and how many times. Identity-verification events, downloads, and link expirations stream into your SIEM or compliance reporting pipeline through webhooks and the REST API.
