ATLANTA, GA — December 7, 2021—IRONSCALES, a leading provider of AI-powered email security solutions, announced today that it has raised $64 million in a Series C funding round led by PSG, a leading growth equity firm partnering with middle-market software and technology-enabled services companies, with participation from existing investors K1 Investment Management and Jump Capital.

IRONSCALES’ cloud-native, API-based email security software platform is self-learning to continuously detect and remediate advanced threats, such as business email compromise, credential harvesting and account takeover in companies’ mailboxes. The platform reduces identification of suspicious mail to seconds at scale across organizations. To complement its phishing detection and incident response capabilities, IRONSCALES’ platform includes a phishing simulation and training module to educate employees and further bolster resiliency against cyber threats. Founded in 2014, IRONSCALES serves over 5,000 organizations globally of all sizes and across industries. The company plans to use the new funding to expand its international footprint and continue to grow its platform’s capabilities.
