About the Technical Reviewers

Tim Draegen has a long history in the email space. As Agari’s director of technical strategy, Tim is responsible for technical innovate and advocacy. Tim works closely with numerous financial institutions, ISPs, and enterprises to design, develop, and adopt the technologies that enable secure, authentication-based email channels. Tim chairs the OTA Email Authentication Committee and is tasked with making the value of email authentication clear to everyone—not just email gurus or security professionals. Prior to Agari, Tim spent a dozen years as a software engineer and security researcher, including a stint at Cisco/IronPort, where in late 2004, he recognized the importance of email authentication and implemented DomainKeys, setting the stage for enterprise-grade protection of email domains and PayPal’s successful 2007–2008 DMARC prototype.

Benjamin Hartwell started with IronPort Systems in 2002 and remained associated with IronPort/Cisco until the fall of 2011. Ben tested, managed, or was a technical advisor for the ESA from version 2.0 to version 8.0. Ben has been involved in quality assurance for 13 years, testing both consumer and enterprise products. He is currently continuing work in the security space, focusing on web security.
