EMAIL

Email Security

Stop phishing and BEC before the inbox, then find and retract campaigns after delivery.

Protect the inbox you already use

Microsoft 365 remains your mail provider.

Cloudflare adds inspection and response around the existing mail flow. Users keep Outlook, their mailboxes, and normal collaboration workflows.

Choose the inspection point

Prevent before delivery, contain after delivery, or combine both.

The deployment determines when Cloudflare sees a message and which actions are available. “Email Security” does not imply every customer must change MX records.

Message anatomy scanner

One email becomes many independent signals—and one final disposition.

Cloudflare evaluates who sent it, how it is written, where links lead, what attachments contain, and whether authentication agrees with the visible identity.

Campaign response loop

Turn one reported phish into campaign-wide containment.

The value is not only the verdict. Analysts need to understand the message, find related copies, remove exposure, and retain an action trail.

Planned Microsoft 365 proof

Start without changing mail flow; earn the inline deployment later.

This is a proposed proof path—not a configured account claim. Use a synthetic demo tenant and harmless fixtures; never send live malware or real employee data.

Say the deployment out loud

The protection claim must match the inspection path.
