Email Security Specialist GreatHorn Locks in $13 Million Investment
Email security specialist GreatHorn has raised $13 million in a funding round led by RRE Ventures and .406 Ventures. Existing investors Techstars Ventures, V1.VC, and Uncork Capital also participated in the round, which boosts the firm’s total capital to $21.8 million.
GreatHorn said it will use the new capital to continue its innovation in the email security space. The company offers organizations a 100%, cloud-native platform designed specifically to defend email systems before, during, and after an attack. The technology’s proactive approach blends integrated threat detection, in-the-moment user education, and comprehensive incident response to combat threats ranging from credential theft and email compromise to ransomware and phishing.
“As we continue to meet customer demand and drive the market,” GreatHorn CEO Kevin O’Brien said, “we remain fundamentally interested in redefining email as a secure system for all users, and ensuring that organizations who have adopted cloud email platforms are not relying on outdated perimeter controls or simple user education to protect their most critical assets.”
GreatHorn’s funding news comes as the company celebrates its third consecutive year of 3x revenue growth, as well as its “rapid expansion into the enterprise market.” RRE Ventures General Partner Raju Rishi praised GreatHorn as being among the “category-defining businesses” the firm prefers to invest in. He credited the company for providing an overhaul in the way that organizations think about protecting their email systems.
“GreatHorn has delivered a platform that comprehensively protects enterprises against the rising sophistication of today’s threats,” Rishi said. “We’re excited to support GreatHorn as the company that continues to build upon its current innovation and grow in the enterprise space.”
Founded in 2015, GreatHorn demonstrated its inbound email security platform at FinovateFall 2017. More recently, the Waltham, Massachusetts-based company was awarded a patent for a new method for detecting email impersonation. GreatHorn began the year with news that its latest version was now enabled to detect credential theft involving Microsoft Office 365 and Google G Suite.
