Blockchain authentication catches the threats others can’t

CEO Fraud

Emails that impersonate executive emails or even those sent fraudulently from their accounts are detected by verifying any email sent to or from a Cloudphish user at any organization.

Spear Phishing

Emails sent from a trusted source are authenticated flagging spear phishing attacks which impersonate an email address or infiltrate a corporate network to send it from their account.

Clone Phishing and Spoofing

Emails that closely resemble legitimate email accounts or domain names can be easily missed. Cloudphish will catch and alert the user to this type of attack even if the message appears safe.

Beyond Traditional Methods

Sophisticated phishing emails can circumvent email security measures like DMARC, DKIM, SPF and signed certificates because they originate from valid domains and senders, just not where you think.

Real-time alerts, front and center

Our Trusted Sender Authentication Network (TSAN) uses blockchain technology to instantly identify phishing attacks that are otherwise undetectable to traditional email security solutions.

Real-time inbox feedback tells employees if an email is safe or not by verifying the sender's identity.
