Outbound email is the leading cause of data loss for all organizations. Microsoft 365’s native functionality needs augmenting with intelligent technology to provide data loss prevention (DLP) suitable for modern enterprises.

Misdirected Emails and Files
The impact of email data loss
of organizations experienced client churn
of organizations suffered direct financial losses
of incidents resulted in disciplinary or legal action against the employees involved
Outlook autocomplete is the leading cause of data loss
Misdirected emails and files is the leading cause of data loss incidents reported to regulators. When people are under pressure, tired, or simply not concentrating, they make mistakes – such as choosing the wrong recipient via Outlook autocomplete or attaching the wrong files to an email.
The static data loss prevention (DLP) solutions delivered by Microsoft 365 and secure email gateways (SEG) don’t understand the anomalies in human behavior to detect accidental email data loss, and they can’t scale to deliver effective DLP for today’s enterprise.
Contextual machine learning and social graph technologies that intelligently detect abnormalities in human behavior
Egress Prevent intelligently detects accidental data loss by email. We use supervised and unsupervised machine learning to deeply understand each individual’s behavior when using email, including the individuals and groups they communicate with and the types of content they share. By understanding what normal looks like, Prevent automatically detects unusual signals for abnormal behavior.
Prevent protects your users in Microsoft Outlook and Outlook Web Access, or on any mobile or web-enabled device.

Stop emailing the wrong people
- 1 Recipient analysis. Social graphing and contextual machine learning algorithms deeply understand a user’s relationships to detect any anomalous recipients.
- 2 Domain analysis. Assesses historic domain interactions for authenticity in order to detect deviations from normal behavior or lookalike domains.
- 3 Interactive and customizable feedback. Egress Prevent provides instantaneous feedback as the user composes their message, without negatively impacting their workflow.
- 4 Clear explanation of risk. An interactive threat panel highlights why there’s a risk, augmenting your security awareness and training (SA&T) program.

Share the right content with recipients every time
- 5 Content inspection and analysis for all attachments. DLP policies supervise machine learning algorithms to coach right vs. wrong. By measuring the subject line and message body against the given aliases, Prevent can detect anomalous content specific to the intended recipients and domains.
- 6 Intelligent notifications. An unobtrusive prompt only alerts users to a potential mistake, and our intelligent technology learns behavior for future emails.
- 7 Anomalous content detection inside the attachments. Smart rules work alongside machine learning to scan content buried inside an attachment and detect any unique identifiers that don’t match up with the intended recipients based on previous or similar user behavior.

Prevent misdirected emails at home or on the go
- 8 Immediate notification within the M365 environment. Your email is never diverted to a proprietary cloud, meaning it’s safe from unauthorized access while productivity remains intact in the event of an outage. Should we spot any risk of a misdirected send, our cutting-edge solution pushes a notification email back to the user.
- 9 Simple explanations of security risks. The email explains clearly why there’s a risk to help educate users and drive employee awareness on security best practice.
- 10 Quick approve/reject workflow. Our sophisticated mobile technology allows users to quickly reject emails in the even of a misdirected send; or they can approve, and the machine learns for next time.

Cut through the noise to highlight the risks that matter
Reporting on threats such as misdirected emails and files in your email flows can be manual and slow. Even worse, systems can throw too much unnecessary information at you, making it harder to make timely and effective decisions.
Egress Prevent's intelligence platform provides simplified dashboards and critical insights so that administrators can quickly cut through the noise, identify email security risks and, where necessary, remediate.

Actionable intelligence
Data and analytics should not overwhelm you with information. Updated in real time, our intelligence dashboard offers insights and statistics into email details, risk levels, authentication checks, communication history, and how your people interacted with Prevent prompts.

What our customers say
Hear from companies and organizations who use Egress Prevent to prevent against data breaches caused by misdirected emails & files.
We chose Egress Prevent because its contextual machine learning applies the intelligence required to genuinely detect when data is being put at risk. It’s able to make the connection between users’ habits and relationships, and what they have sent by email in the past, linking with that an intelligent understanding of the sensitivity of data contained in emails and attachments. So it can stop a user accidentally sending something that might have otherwise slipped through the cracks with static rules-based technology.
