O365 is not enough

The intelligent solution for improving security in O365

With the continued, rapid adoption of O365, many organizations are looking to overlay additional technologies to enhance protection of shared data. Find out why - download Why Your Company Needs Third-Party Solutions for Office 365 by Michael Osterman.

Egress offers easy-to-use, intelligent email security tools that prevent breaches and protect data as emails are sent from O365. This includes content analysis and anomaly detection to stop accidental and intentional data breaches, and message-level encryption and sophisticated controls to secure sensitive information.

Egress also provides granular reporting for organizations’ admins to monitor the data being shared within their email networks for compliance purposes.

Prevent data breaches

Using machine learning and content analysis, Egress prevents emails and attachments being sent to the wrong people from within O365. This includes detecting when recipients have been added accidentally via Outlook autocomplete, the wrong files have been attached to an email, or content within an attachment hasn’t been redacted or removed by the sender.

This anomaly detection can also be used to detect occasions where staff may be exfiltrating information from within an organization.

Protect regulated data

Egress offers enhanced message-level encryption and control for shared data, including email recall, watermarking, and blocking actions such as forwarding emails and attachments. Egress can also enforce ethical walls and dynamically update recipient whitelists as senders’ behavior changes.

These advanced DLP features support compliance with data privacy regulations like GDPR, HIPAA and the upcoming CCPA.

Make it easy

Egress’ email security tools have been designed to simplify users’ experiences. For senders, this includes dynamic prompts to tell them when emails and attachments should be encrypted. For recipients, we provide flexible authentication that makes it easier for trusted users to access content but raises appropriate barriers for untrusted users.
