Exaforce, an AI-native security operations platform and pioneer in agentic security, has closed a $125m Series B funding round — one of the largest raises to date in the emerging AI SOC market.
The round drew participation from HarbourVest, Peak XV, Mayfield, Khosla Ventures, Seligman Ventures and AICONIC. Arriving just twelve months after a $75m Series A, the new investment brings the company’s total funding to $200m. Proceeds will be directed towards scaling the platform, strengthening its real-time reasoning capabilities, and supporting international expansion.
Exaforce’s architecture sets it apart from conventional AI security approaches. Where many AI-enabled SIEMs and SOC triage tools reconstruct context during an investigation — querying logs, calling APIs and correlating signals after the fact — Exaforce builds and maintains a real-time security knowledge graph at the point of data ingestion.
By connecting security events, identities, permissions, configurations, code, files and cloud activity as they arrive, the platform enables agents to complete the same investigative queries in under a minute, representing a tenfold reduction in time and a significant decrease in tokens per investigation. The company argues that correlating signals at ingest, rather than at query time, is the only architecture capable of supporting both real-time triage and proactive detection.
The approach also carries implications for reasoning quality. Because every event is linked to its identity and every resource connected to its associated permissions, the platform’s agents navigate real relationships rather than inferring them from fragmented data sources. The company says this translates to fewer false positives, higher-fidelity detections and response recommendations that security teams can act on with greater confidence.
Over the past year, Exaforce grew its headcount to more than 130 employees and processed millions of investigations across its expanding customer base. Recent product developments include Vibe Hunting, with the company reporting measurable outcomes across detection, investigation and response workstreams.
The Series B will fund continued development of the core platform, including multi-model AI capabilities and the real-time knowledge graph, as well as go-to-market expansion into key regions including Japan and Europe. Exaforce also plans to invest in customer success, research, managed detection and response (MDR) oversight, and support functions.
Exaforce chief executive officer Ankur Singla said, “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.”
Khosla Ventures founder Vinod Khosla said, “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.”
Linx Security, an identity security and governance platform, recently raised $50m in a Series B funding round led by global software investor Insight Partners, with continued participation from existing backers Cyberstarts and Index Ventures.
