Cloudflare Area 1 Email Security

Protect your organization from modern attacks against your #1 business application — email.

Don’t trust your inbox. Defend against evolving threats and gain insights into bad actors’ next moves, with Cloudflare Area 1.

Preemptively block phishing, Business Email Compromise attacks, malware-less fraud, and other targeted email threats. And enhance your cloud suite protection with our seamless Microsoft 365 and Google integrations.

The Cloudflare Area 1 Difference

Stop attacks days before launch

Area 1 preemptively hunts for phishing infrastructure, sources, and delivery mechanisms to block campaigns at the onset.

Extend Zero Trust to email security

Comprehensively block campaigns across different attack vectors, even when messages are from “trusted” senders or domains.

Save IT time and resources

Replace ineffective SEGs with cloud-native, API-first email security, with nothing to install or endlessly “tune.”

Simplify threat defense

Get end-to-end phishing triage and response, plus seamless integration with SIEMs and other security tools.

Slide 1 of 3

Preemptively block phishing attacks

  • Uncover new tactics used by malicious actors to block phishing in real-time, versus waiting days or weeks for signature updates.
  • Neutralize multi-channel phishing attacks that span email and web delivery, by turning on Area 1's integration with Cloudflare Browser Isolation.
  • Accurately detect and contain low-volume targeted phish without requiring large attack sample volumes.
  • Get visibility into compromised accounts and domains, as well as new, lookalike, and proximity domains impersonating your brand.


Stop Business Email Compromise attacks — including ‘long con’ invoice fraud

  • Sentiment analysis looks at message intent, tone, sender relationships, and other attack signals.
  • Uncover sophisticated BEC and supplier account takeovers through sender trust graphs and entire thread analysis.
  • Automatically block, quarantine, and escalate fraudulent financial communications.

Learn how to detect and block BEC — a $43 billion global problem — with six advanced techniques.


Secure your cloud email

  • Replace redundant SEGs — which we often see miss over 30% of phishing emails — with best-in-class cloud-native email security.
  • Proactively discover and block socially-engineered phish that bypass Google Workspace and Microsoft 365 with ATP.
  • Eliminate the need for hardware and “tuning” to keep up with new threats.

Seamlessly fits into any email security stack

  • Deploy in minutes without any hardware, agents, or appliances.
  • Choose the deployment option best for your organization — inline, API, or multi-mode.
  • Extend email protection to your chosen vendors and partners.
  • Expedite SOC investigations with post-delivery message retractions and integrations with SIEM/SOAR platforms.

Why Zero Trust + Email Security?

Simplify the way you protect SaaS applications

Protect users and data with a Zero Trust approach

The traditional tools used to connect employees to corporate apps grant excessive trust, increasing your cyber risk.

The Cloudflare Zero Trust platform replaces legacy security perimeters, and ensures that all traffic in and out of a business is verified and authorized.

As part of the Cloudflare Zero Trust portfolio, Area 1 helps increase visibility, eliminate complexity, and reduce risks for remote and office users alike.
