Agari Raises $22 Million to Expand Email Protection Platform

Agari, a provider security solutions that help detect email-based cyberattacks, today announced that it has raised $22 million in a Series D funding round, bringing the total raised by the company to $44.7 million. The company previously raised $15 million in a Series C funding round back in September 2014. 

Agari says that its email security platform uses behavioral trust models to help protect enterprises and their customers from email-based data breaches, financial theft, malware delivery, credential theft and ransomware.

The company offers its Agari Enterprise Protect solution, which helps organizations protect themselves from spear phishing attacks. It also offers its Agari Customer Protect solution, which protects consumers from email attacks that spoof brands.

San Mateo, Calif.-based Agari played a key part in the investigation and operation led by Microsoft Microsoft that successfully disrupted more than 1,000 botnets using the Citadel malware back in June 2013. The investigation began in early 2012, during which FS-ISAC performed forensics analysis on terabytes of email data collected by Agari.

As a founding member of DMARC.org in 2012 and contributing author of the open standard DMARC (Domain-based Message Authentication, Reporting and Conformance) that underlies Agari’s solutions, Agari helps companies gain visibility into the legitimate and fraudulent use of their domains and email channel, enabling them to protect their customers, employees, and brands from email-based cybercrime.

The company claims that its Trust Platform protects more than 85 percent of consumer mailboxes in the United States and analyzes more than 10 billion messages per day. Overall, the company says that its platform prevented 3.5 billion fraudulent emails from being delivered in 2015.    

Norwest Venture Partners led the funding, with all existing investors contributing to the round, including Alloy Ventures, Battery Ventures, First Round Capital, Greylock Partners, and Scale Venture Partners.
