Atlas Email Security · Add-On

Go Deeper With Atlas Email Security.

with Sublime

Atlas Email Security adds Sublime as a native engine inside Atlas. Clear threats are remediated automatically. Anything else goes to our SOC. It connects to Microsoft 365 over API with no MX changes, and it’s an add-on to any Atlas Package, with User Reported Phishing included.

Caught on Arrival

Reads intent, sender behavior, links, attachments and QR codes. Clear threats are quarantined, moved to spam or bannered.

Every Verdict Explained

Each flagged email carries its Attack Score and detection logic.

Removed From Every Inbox

Our SOC pulls the message or the whole campaign, including calendar invites, from every mailbox.

Detection and Response for Email

Email is one more signal in the Atlas loop. Our SOC correlates it with the rest of your environment, so a phishing email, the click and the sign-in that followed are worked as one attack.

The Whole Attack, in One Finding.

A phishing email is rarely the whole story. Here's what happens when one reaches an inbox.

  1. It's flagged.

    Your email security raises an alert, or an employee reports the message.

  2. Atlas takes it in.

    The alert lands in Atlas with the rest of your signals, not in a separate console.

  3. Atlas investigates.

    Atlas AI and our analysts look across your endpoint, identity, network and cloud activity for what happened next.

  4. Our SOC acts.

    Respond sthrough your email tool, within your rules, pulling the message or campaign from every mailbox.

  5. You see all of it.

    The alert, evidence and every action in one Atlas Finding.

That's the difference between deleting an email and stopping an attack.

Machine Speed. Human Judgment. Your Rules.

You Set the Rules

Our SOC acts within the response settings you choose. Nothing happens outside them.

See the Evidence

Every alert arrives in Atlas with the evidence behind it, so you can check our work.

Your Admins Keep the Keys

Allow and block lists, exclusions and quarantine release stay with your team.

Experts on the Loop

Our 24/7 analysts own every response and record every action. They never log in to your mailboxes.

Email Detection and Response FAQ

What is email detection and response from eSentire?

It's how eSentire brings email into Atlas as a signal. Atlas takes in alerts and logs from your email security, plus the phishing your employees report. Our 24/7 SOC investigates each one alongside your endpoint, identity, network and cloud activity, and responds. For the deepest coverage, Atlas Email Security adds a native email detection engine inside Atlas.

How does email signal get into Atlas?

Four ways. Atlas Log ingests logs from your email protection tools. User Reported Phishing sends your employees' reports to our SOC. Bi-directional integrations bring Proofpoint alerts into Atlas and send response back through Proofpoint. Atlas Email Security, with Sublime, inspects every message natively inside Atlas.

Do I need to replace my email security?

No. Atlas works with the email security you already run. If you want deeper detection and response, Atlas Email Security runs alongside your gateway or replaces it.

Does Atlas work with Proofpoint?

Yes. Atlas connects to Proofpoint in both directions. Proofpoint alerts land in the same Atlas investigation as the rest of your environment, and our SOC responds back through Proofpoint. The Proofpoint report button also works with User Reported Phishing.

Does Atlas work with Mimecast?

A bi-directional Mimecast integration is coming soon. Atlas can ingest Mimecast logs today through Atlas Log.

What is Atlas Email Security?

Atlas Email Security is an add-on to any Atlas Package for organizations that want our deepest email coverage. It uses Sublime as a native engine inside Atlas to check every message as it lands and automatically remediate clear threats, explain each verdict with its Attack Score and detection logic, and send anything that needs further investigation to our SOC analysts, who can remove a message or whole campaign from every inbox. User Reported Phishing is included.

How does User Reported Phishing work?

Employees report a suspicious email with the report button they already use. Our SOC investigates every report, closes false reports and removes real phishing. It works with the Microsoft 365 and Proofpoint report buttons today.

What does the eSentire SOC do when a malicious email gets through?

It depends on how email reaches Atlas. With Proofpoint, our SOC responds back through Proofpoint. With Atlas Email Security, clear threats are remediated automatically at delivery. Anything that needs further investigation goes to our analysts, who quarantine or trash the message or the whole campaign, and remove calendar invites, from every mailbox. Every action runs within the response settings you choose and is recorded in the Atlas finding.

Do I need to change my MX records?

No. Integrations and Atlas Email Security connect over API, so your mail keeps flowing the way it does today.

Does it work with Google Workspace and Microsoft Defender for Office 365?

Atlas Email Security supports Microsoft 365 today and augments Microsoft Defender for Office 365. Google Workspace support is coming soon.
