What's New
The following new features are now available in TMCAS:
- Suspicious sender detection based on newly observed email addresses
For Exchange Online, TMCAS supports detecting an external sender as suspicious when the sender has not sent any email in at least the past 30 days. Newly observed addresses might be a sign of a threat as they are often used by malicious actors to launch attacks.
- Quarantined email preview
For Exchange Online (Inline Mode), TMCAS allows administrators to preview quarantined emails in the management console and end users to preview their quarantined emails in the TMCAS add-in for Outlook. This helps administrators and end users determine further actions to take without downloading the emails.
- Inline Protection for Gmail inbound messages (preview)
For Gmail, TMCAS provides Inline Protection to scan inbound emails before they reach their destinations, with no MX record change required. This protection mode blocks threats before they can reach your users' mailboxes.
- "Risky User Detection" dashboard in new console (preview)
In the new management console, TMCAS provides a dashboard tab for a centralized view of risky users in your organization, including top users distributing or receiving malicious content, top users triggering high-risk events, and the overall user risk trends.
