AppRiver Announces Acquisition of Roaring Penguin Software

The Ottowa-based anti-virus and anti-spam solution provider Roaring Penguin has been acquired by cloud-based cybersecurity firm AppRiver.

AppRiver was founded in 2002 primarily to provide email security solutions to help businesses block the barrage of spam and malicious messages and help to keep inboxes and networks malware free. Over the past 16 years, AppRiver has expanded its range of cybersecurity solutions to include a host of malware protection solutions, in addition to an email encryption service, email archiving solution, and email continuity services.

AppRiver is also one of the world’s largest providers of Office 365 and Secure Hosted Exchange. Today, more than 60,000 companies around the world use AppRiver products to secure their email systems and protect against cyberattacks.

The company is focused on increasing its customer base and becoming the go-to company for cloud cybersecurity and productivity solutions for the SMB market and channel partners serving SMBs, as well as increasing its Office 365 business. The acquisition will certainly help with the latter. AppRiver has previously been restricted to the US, but the physical base in Canada will allow the firm to grow its Office 365 business north of the border.

Roaring Penguin has built up a significant customer base in Canada, North America, and Europe and provides anti-spam and anti-virus protection to a broad range of companies, including universities, commercial businesses, ISPs, managed service providers, and government organizations.

The incorporation of Roaring Penguin’s machine driven anti-spam technology into the AppRiver’s SecureTide platform will improve performance and make AppRiver’s MessageSniffer engine more effective. Similarly, the inclusion of AppRiver’s human cognition into the Roaring Penguin platform will enhance its capabilities.

“The result will be spam and virus protection that is more effective than either could be individually or even deployed in-line. The whole really is greater than the sum of the parts,” said Joel Smith, co-founder and CTPO of AppRiver.

The acquisition is expected to be completed by in the summer of 2018.
