Marlin portfolio company AppRiver acquires Total Defense

LOS ANGELES, October 10, 2018 – Marlin Equity Partners (“Marlin”) is pleased to announce that it has acquired Total Defense, Inc. (“Total Defense”), a leading provider of subscription-based endpoint security software, including virus and malware protection, for consumers and small businesses. Total Defense will be merged with AppRiver, a Marlin portfolio company, further strengthening AppRiver’s suite of cloud-based security and productivity services.

“Our focus in 2018 has been expanding our capabilities to become the channel’s most trusted provider of SMB security solutions.” said Kevin Hatch, AppRiver’s CFO. “Our partners have consistently told us they prefer the simplicity of dealing with one vendor and the high value that our award-winning Phenomenal Care® customer service and powerful security services provide.”

The integration of AppRiver’s threat intelligence and analysis foundation into an endpoint security solution provides another powerful layer of cyber-defense for small and mid-size businesses. In the rapidly evolving IT channel, partners are searching for more effective security solutions and new sources of recurring revenue, while aiming to minimize the uncertainty and complexity that result from using multiple providers.  With the acquisition of Total Defense, and the acquisition of Roaring Penguin in March, AppRiver has positioned itself as a one-stop provider with comprehensive security capabilities and extensive channel experience.

“Total Defense’s endpoint protection is highly complementary to AppRiver’s existing suite of security products and we are excited to leverage these capabilities to provide a best-in-class solution to AppRiver’s global customer and partner base,” said Peter Chung, a managing director at Marlin. “We remain committed to driving growth through additional acquisitions that enhance AppRiver’s technology portfolio and continue to deepen the company’s value proposition to its SMB customers.”
