Abstract Security has raised a $25 million Series A extension co-led by Cheyenne Ventures and Atlantic Vantage Point, bringing the company’s total funding to nearly $50 million. The round follows a year of significant growth, including 380% annual recurring revenue growth, 264% net revenue retention, a tripled customer base and continued expansion into larger enterprise accounts.
The new capital will support broader in-stream threat detection, deeper AI capabilities across security operations workflows and continued go-to-market expansion. Abstract’s streaming-first, composable security operations platform enables organizations to run detections while data is still in motion, route security data across preferred tools and storage destinations and reduce dependence on monolithic SIEM architectures. The company’s approach reflects growing enterprise demand for more flexible, AI-native security operations infrastructure.
