Exaforce has announced a $125 million Series B financing round, one of the largest ever in the emerging AI security operations center space, bringing the San Francisco-based company’s total funding to $200 million. The round includes participation from HarbourVest, Peak XV, Mayfield, Khosla Ventures, Seligman Ventures, and AICONIC. The capital will be used to scale the company’s AI-native security operations platform, deepen its real-time reasoning capabilities, and expand globally, including into Japan and Europe. The raise comes just one year after Exaforce’s $75 million Series A.
Exaforce takes a fundamentally different architectural approach from most AI security operations products on the market. While many tools focus on triaging alerts after they trigger — requiring agents to reconstruct context during an investigation through hundreds of queries across logs, APIs, and signals — Exaforce builds and maintains a real-time security knowledge graph at ingest, connecting security events, identities, permissions, configurations, code, files, and cloud activity as they arrive. The company said its agents can answer investigative questions in under a minute, representing a tenfold reduction in time and a significant reduction in computing cost per investigation, because relevant context is retrieved rather than reconstructed on demand. The result, the company said, is fewer false positives, higher-fidelity detections, and response recommendations that security teams can act on with confidence.
In the past year, Exaforce grew to more than 130 employees and processed millions of investigations across its customer base, which spans healthcare, technology, financial services, and other high-target industries. The company also launched products including Vibe Hunting and expanded its managed detection and response service providing 24/7 expert coverage alongside the platform. The funding will also support continued investment in customer success, research, MDR oversight, and support to help customers improve response speed and resilience across critical environments.
KEY QUOTES:
“We built Exaforce to be the platform defenders actually work in, not just an AI layer on top of existing tools. It starts with a real-time knowledge graph that gives agents complete context from the start, and extends into rich investigation and visualization experiences that put security engineers and AI agents on the same page. This funding lets us deepen that platform and bring it to security teams on a global scale.”
Ankur Singla, CEO, Exaforce
“The biggest opportunity in enterprise security is flipping the economics, so that defenders, not attackers, hold the leverage. When the cost of defense drops by an order of magnitude, the entire calculus of security changes. Exaforce is the architecture that makes that possible.”
Vinod Khosla, Founder, Khosla Ventures
