Activate phishing-resistant MFA with Cloudflare

Thwart phishing scams by enforcing strong authentication

Phishing remains one of the most prevalent kinds of threats—and it is often just the first step in a larger attack. Implementing FIDO2-compliant multi-factor authentication (MFA) as part of a Zero Trust security approach neutralizes the threat posed by multi-channel phishing.

THE CLOUDFLARE DIFFERENCE

Enhance your access management

Augment your identity provider (or multiple providers) with Zero Trust Network Access (ZTNA) to easily enforce FIDO2 MFA across more resources.

Maximize MFA impact

Avoid vulnerabilities of other authentication methods. Unlike one-time PINs, FIDO2 MFA cannot be intercepted by an attacker. Implement MFA broadly — and require it — through Zero Trust policies.

HOW IT WORKS

Defeat phishing with FIDO2 MFA and Cloudflare

Cloudflare’s Zero Trust platform can enforce FIDO2 MFA consistently across SaaS, self-hosted, and non-web resources.

Implement Cloudflare’s ZTNA service to apply strict contextual verification for accessing all your organization’s resources.
Bolster security with FIDO2-compliant MFA that makes it nearly impossible to intercept or steal users’ credentials.
Selectively enforce strong MFA, starting with sensitive apps. Go beyond just supporting FIDO2 MFA and start to require it.
Enable broad deployment. Not all apps support FIDO2 MFA natively. As an aggregation layer, Cloudflare’s ZTNA service helps roll it out to all resources.

Halting an SMS phishing attack on Cloudflare

The Cloudflare security team needed to rapidly address a phishing attack that attempted to harvest and then use Okta login credentials from employees. Though the attackers successfully stole credentials and attempted to log in, they could not overcome the security key login requirement of Cloudflare’s Zero Trust implementation.

Requiring FIDO2-compliant MFA, like security keys, as part of Zero Trust access policies for all users and apps can strengthen the barrier against multichannel phishing attacks.

“While the attacker attempted to log in to our systems with compromised credentials, they could not get past the hard key requirement.”
