Email monitoring

Once you have chosen a domain to scan, Email Security allows you to monitor the traffic scanned from your email inboxes.

To monitor your inbox:

1. Log in to Zero Trust ↗.
2. Select Email Security.
3. Under Email Security, select Monitoring.

The dashboard will display the following metrics:

• Email activity
• Disposition evaluation
• Detection details
• Impersonations
• Phish submissions
• Auto-move events
• Detection settings metrics

Email activity

Email activity aggregates statistics about emails scanned and dispositions assigned (the number of email flagged due to a detection) within a given timeframe.

To view the live number of email scanned and dispositions scanned, enable Live mode.

Disposition evaluation

Email traffic that flows through Email Security is given a final disposition, which represents Email Security’s evaluation of that specific message.

Disposition evaluation displays the following dispositions:

• Malicious: Traffic invoked multiple phishing verdict triggers, met thresholds for bad behavior, and is associated with active campaigns.
• Spoof: Traffic associated with phishing campaigns that is either non-compliant with your email authentication policies (SPF ↗, DKIM ↗, DMARC ↗) or has mismatching Envelope From and Header From values.
• Suspicious: Traffic associated with phishing campaigns (and is under further analysis by our automated systems).
• Spam: Traffic associated with non-malicious, commercial campaigns.
• Bulk: Traffic associated with Graymail ↗, that fall in between the definitions of spam and suspicious. For example, a marketing email that intentionally obscures its unsubscribe link.

Detection details

Detection details displays information about:

• Malicious disposition:
  • Email threat types: Top malicious threat types, and their number relative to the total amount of malicious threats received.
  • Targeted users: Top number of emails targeted, and their number relative to the total amount of malicious targets.
  • Malicious links: A graph displaying the total number of malicious links and their distribution throughout the month.
  • Malicious attachments: Number of malicious attachments, and the top types of malicious files received.
• Suspicious disposition:
  • Suspicious threat types: Top suspicious threat types, and their number relative to the total amount of threats received.
  • Suspicious targets: Top number of emails targeted, and their number relative to the total amount of malicious targets.
  • Suspicious links: A graph displaying the total number of suspicious links and their distribution throughout the month.
• Spoof disposition:
  • Spoof users (impersonated names): Top number of impersonated names, and their number relative to the total number of detection received.
  • Spoof targets: Top number of targeted emails.
  • Sender v. envelope mismatch: This field indicates the number of mismatches between the email address the message was sent from, and the email address the message was actually sent from.

Impersonations

Impersonations are a form of phishing attack where the actor pretends to be someone else to steal sensitive information.

Impersonations displays the number of targeted users, and a chart describing the total number of impersonation attempts.

• To view all targeted users, select View all targeted users.
• To view all impersonation emails, select View all impersonation emails.
• To view impersonated users, select View impersonated users.

Refer to Trusted domains to add a trusted domain, and Impersonation registry to add a user to the impersonation registry.

Phish submissions

Phishing is a type of attack that involves stealing sensitive information with the aim of using and selling the information.

A phish submission happens when a user or an administrator reports a phishing attack. Refer to Phish submissions to learn how to submit a phish.

Phish submissions displays the following information:

• All submissions: The total number of phish submissions.
• User submissions: The number of phish submissions reported by your users.
• Admin submissions: The number of phish submissions reported by an administrator.

Select Review submissions to review a filtered list of phish submissions reported by your team.

Auto-move events

Auto-move events are emails moved to different inboxes based on the disposition Email Security assigned.

This panel shows you the total number of auto-moves and the source folder from which these retractions are originating from.

Refer to Auto-moves to configure auto-move events.

Detection settings metrics

Detection settings metric displays information about:

• Allowed traffic: Traffic that Email Security will exempt emails that match certain patterns from normal detection scanning. Allowed traffic shows metrics on emails that were allowed to go through user inboxes.
• Blocked traffic: Traffic that Email Security automatically blocks from senders. Blocked traffic shows metrics on emails that were blocked from user inboxes.
• Domain age: The number of days since domain registration.

Select Configure to configure policy and rules for allowed traffic, blocked traffic and domain age.
