Marlin portfolio company AppRiver acquires Roaring Penguin

LOS ANGELES, March 26, 2018 – Marlin Equity Partners (“Marlin”) is pleased to announce that it has acquired Roaring Penguin Software Inc. (“Roaring Penguin”), an Ottawa-based provider of email security solutions. The company offers anti-spam and anti-virus email filtering software to a broad base of managed service providers, internet service providers, universities, governments and commercial businesses throughout North America and Europe. The acquisition bolsters AppRiver’s footprint in Canada, further diversifying its global customer base and adding a local presence in a key market from which AppRiver can accelerate sales of its proprietary cybersecurity solutions and its Office 365 franchise.  Roaring Penguin’s intellectual property will be leveraged to enhance SecureTide, AppRiver’s e-mail security solution.

“This acquisition is the first of a series of initiatives aimed at establishing AppRiver as the global go-to cloud cybersecurity and productivity company for SMB customers and the channel partners who serve them,” said Michael Murdoch, AppRiver’s president and CEO. “The combination with Roaring Penguin gives us the ability to establish a leading Office 365 business in Canada, and the integration of Roaring Penguin’s anti-spam technology with SecureTide allows us to further differentiate our product offering. With our enhanced SecureTide product, expanded geographic presence and new Nautical platform, we believe we are well positioned to help our partners succeed in a cloud-centric world.”

“The acquisition of Roaring Penguin reflects our commitment to strategically invest around AppRiver’s core competency in email and expand upon its credentials in cybersecurity,” said Peter Chung, a managing director at Marlin. “Roaring Penguin offers a unique opportunity to add new features and capabilities to SecureTide’s existing technology, while establishing a key foothold in the Canadian SMB market as part of AppRiver’s continued international expansion. We are excited to partner with the Roaring Penguin team and welcome a new set of customers to the AppRiver family.”
