Increased Threat Visibility

With visibility spanning ISPs and mobile carriers, Cloudmark correlates email threat telemetry data into its Global Threat Network, including intelligence derived from malware campaigns and targeted attacks like spear phishing and email fraud.

By combining the threat intelligence from Cloudmark with the Proofpoint Nexus platform, we can better protect all our customers – both enterprises and ISPs – from today’s rapidly evolving threats.

Cloudmark’s Global Threat Network data will be incorporated into Proofpoint Nexus, including:

  • Messaging threat telemetry from billions of daily emails.
  • Threat intelligence around malicious domains that will complement Proofpoint’s Email Fraud Defense (EFD) and Domain Defense products.
  • Visibility into fraudulent and malicious SMS messages directed to mobile carriers worldwide.

Cloudmark and Proofpoint customers will benefit from increased effectiveness across the product suite. Proofpoint plans to continue Cloudmark’s service provider products with an ongoing roadmap leveraging the combined capabilities of both companies.
