Email security startup Greathorn nets $13m in funding

GreatHorn, an email security platform protecting organisations before, during and after attacks, has netted $13m in its new funding round.

US-based venture capital firms RRE Ventures and .406 Ventures co-led the investment. Participations also came from existing Greathorn backers Techstars Ventures, V1.VC and Uncork Capital.

The funding comes after a third consecutive year of triple-digit revenue growth and rapid expansion, it claims. Proceeds from the round will be used to strengthen its place within the email security market.

GreatHorn offers an entirely cloud-native platform dedicated to comprehensive email threat protection, threat detection and response services. Its software can protect an organisation from threats such as individual and brand impersonations, credential theft attempts, malware, ransomware, and other advanced social engineering-based phishing attacks.

The cybersecurity company secures an enterprise at every endpoint from inline pre-inbox analysis through to time of delivery, and post-delivery incident response and continuous analysis.

RRE Ventures general partner Raju Rishi said, “Despite decades of experience and billions of dollars spent, the email security industry is no closer to making email safe for businesses. By rethinking how we approach email security, GreatHorn has delivered a platform that comprehensively protects enterprises against the rising sophistication of today’s threats.

“We’re excited to support GreatHorn as the company continues to build upon its current innovation and grow in the enterprise space.”

Last year, RRE Ventures closed its seventh venture fund on $265m with an eye on the financial services, space and robotics, media and 3D printing, markets, among others.

Earlier in the month, fellow email security platform Vade Secure closed a €70m venture round led by General Catalyst. The cyber company utilises threat intelligence to detect targeted email attacks and unknown signature-less threats.
