Outlook 365 Encryption Features

Send secure Office 365 emails with a single click. The Egress Secure Email and File Transfer Office 365 add-in lets users easily encrypt emails in the familiar Office 365 environment, without interrupting their workflow. The intuitive interface can be set up to prompt users to choose the right level of message encryption or configured to dynamically detect sensitive content and automatically apply policy-based encryption.

Flexible real-time email security. Security risks change all the time, so the Egress Office 365 add-in enables users to apply appropriate security controls and encryption to emails and attachments - even if they have already been sent. Recipients can be added or removed, and access rights given or revoked at any point after the email is sent.

Desktop encryption secures data at rest. Inbox folder data is protected from mailbox compromise with message encryption at rest, securing the email journey from end-to-end.

Why Encrypt Office 365 Emails?

Guard against malicious email data breaches. Cloud-based email is flexible and scalable, but it is also a target for cybercriminals. Organisations that want to reap the benefits of Office 365 must also ensure it is secure. Encrypting emails with Egress protects messages in transit and once they reach the recipient, going beyond native Office 365 encryption to provide added assurance.

Ensure compliance. Regulated companies and organisations need to go further to protect sensitive data exchanged via email. Egress enables automated policy-based Office 365 email encryption to meet compliance requirements and prevent data breaches. Plus, full end-user auditing and analytics enable organisations to track the journey of their secure data to monitor their compliance position and meet GDPR and industry-specific regulations.

I’d like to get more technical

Going beyond Office 365 message encryption. Office 365 encryption relies on Transport Layer Security (TLS) to send unencrypted messages to a central server for storage until they are accessed by the recipient via weblink. Egress overcomes this initial encryption gap by securing messages within the sender’s Outlook environment for truly secure end-to-end encryption. Messages are encrypted with AES 256-bit encryption.

Certified secure. Egress for Office 365 is certified to ISO27001:2013 and is the only email encryption solution that has achieved Commercial Product Assurance (CPA) from the UK Government’s National Cyber Security Centre (NCSC).
