Bracket

Bracket is Mailprotector's email encryption product for MSPs that need to protect sensitive messages and files across their clients' email environments. It works with any email client on any device. A sender wraps the subject in brackets and sends from the email client they already use. Bracket intercepts the message in transit and encrypts it automatically. The recipient gets a secure link in their inbox and opens the message in any browser without needing a password, creating an account or installing anything. Key capabilities include: One-time sign-in links expire after 15 minutes, work only once, and are locked to the requesting device. All messages and files are encrypted with AES-256 in transit and at rest. Encryption keys are geographically distributed and automatically rotated. Users can add multi-factor authentication at sign-in for an extra layer of identity verification. A personal data key can also be required if a zero-access boundary is needed. Bracket Share is included with every license. Each user gets a personalized file-transfer page for securely exchanging up to 1GB and 25 files per share. Bracket can also trigger automatically through Shield's Email Traffic Control or CloudFilter's SafeSend when sensitive content is detected. Bracket carries the HIPAA Seal of Compliance from the Compliancy Group and is SOC 2 Type 2 certified. Bracket gives MSPs encryption that fits the way clients already work. Sensitive information gets protected without a password-reset queue for technicians. "There's no encryption platform that's easier to use than Bracket. We love the ease of setup and not having extra management steps. And users love the simplicity too." Tim Knarr, The 20 MSP "The best part of Bracket is that it solved our biggest headache with encrypted email. Even our most challenging clients can use it without calling us every time." Dick Borrelli, Newnan Computers "The end user training is literally dummy proof. You simply throw brackets around the subject. We also love that Bracket includes secure file transfer at no cost." Aaron Gurgul, Watchdog Cyber
