Painless encrypted email

People hate email encryption, so we decided to make it better.

When developing Bracket, our product team started from scratch by researching and listing all the things people hate about email encryption. It was a pretty long list, but what we found is that people generally don't like to install things that have to be updated, they don't like creating accounts for things they only rarely use, and they especially hate having to remember passwords. People simply want things to work without having to jump through lots of hoops.

With this in mind, we engineered and designed Bracket to be the ideal encryption product. Bracket still lets you securely send encrypted email containing corporate and financial data, personal info, legal docs, medical records, but it's so much easier for people to use. Keep reading to see why you should be excited.


Ultra-secure data encryption

Don't let Bracket's ease of use fool you. The encryption techniques we employ to secure your email data are state of the art. Bracket is built on a distributed, multi-layer AES256 encryption design with automatic key rotation. This means you never have to wonder if your data is safe.

Inbox authentication

Lightning fast sign in without sacrificing security

Securely sign in without a password

Simply request to sign in using your email address, then click the secure link from your inbox (the same way password resets are handled most of the time). Bracket bakes in extra security so it's actually more secure than password logins.

Expiring, one-time-use links

Bracket sign-in links expire 15 minutes after being delivered. In addition, each sign-in link only works once, so you never have to worry about someone rummaging through your inbox and opening old links.

Geolocation of sign in requests

As an addional layer of security, sign-in request notifications also include the requesting device IP and approximate location.


Advanced device fingerprinting



Send from any email client on any OS

Email encryption is usually constrained to a specific operating system or mail client, but Bracket frees you up to send encrypted email from literally any email client. So whether your users prefer iPhone, Android, Windows, Linux, or PC (or maybe they just can't let go of their Blackberry)... it simply doesn't matter with Bracket.

No apps or plugins to install

Most encryption solutions rely on downloading and installing numerous apps and plugins depending on where you're sending from, but Bracket takes a different approach. To send an encrypted email with Bracket, just wrap the subject in brackets and send it on its way. It's really that simple.


Ephemeral message storage

Sensitive data shouldn't default to being kept forever. With Bracket, all data is temporary and there are no mailbox quotas to keep track of. Just send and receive secure messages and go on with your day. By default, messages expire in 1 year, but you can set any message to expire sooner if you wish.

We've also made it easy to securely get your data out of Bracket and back in to the other email systems you use that are designed for retention, discovery, and reporting. Seamless archive integration allows you to automatically have your data securely journaled to an archive. The optional 'Export to Inbox' feature even allows users to instantly and securely transfer the message to their normal email inbox.

Personal data key

A personal data key gives you ultimate control of your encrypted message data. When you enable this feature, all of your messages are encrypted in a way which requires the personal data key in order to decrypt the data. And since this key is never stored in Bracket, only you hold the key to reading your messages. You control the key, you control your data.
