Agentic security operations startup Exaforce Inc. today announced that it has raised $125 million in new funding to scale up its AI-driven security operations platform and expand its real-time threat reasoning capabilities.

Though not confirmed directly by Exaforce, TechCrunch reports that the round was raised at a valuation of $725 million.

Founded in 2023, Exaforce sells what it calls an agentic security operations platform. The product combines a real-time security knowledge graph with AI agents the company calls Exabots and is supported by a managed detection and response service that monitors customer environments around the clock.

The company argues that conventional AI-enabled security information and event management tools, along with newer AI SOC triage products, force agents to reconstruct context every time an alert fires. That process involves querying logs, calling application programming interfaces and correlating signals after the fact, sometimes requiring hundreds of queries per investigation. Exaforce instead builds a security knowledge graph at the point of data ingestion, linking events, identities, permissions, configurations, code, files and cloud activity as they arrive.

The company claims its agents can answer investigative questions in under a minute, a 10-times reduction over query-time approaches, while consuming fewer tokens per investigation. The architecture also produces fewer false positives because agents follow real relationships between events rather than inferring them on demand.

“We built Exaforce to be the platform defenders actually work in, not just an AI layer on top of existing tools,” Chief Executive Ankur Singla said in a statement. “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.”

Exaforce has seen strong growth and has increased its headcount to more than 130 employees over the past year and has processed millions of investigations across its customer base.

The Series B round was backed by HarbourVest Partners, Peak XV Partners, Mayfield Fund, Khosla Ventures, Seligman Ventures and AICONIC. Exaforce plans to use the funds to advance its core platform, including multi-model AI development and to expand its go-to-market presence in Japan and Europe.

“The biggest opportunity in enterprise security is flipping the economics so that defenders, not attackers, hold the leverage,” said Vinod Khosla, founder of Khosla Ventures. “When the cost of defense drops by an order of magnitude, the entire calculus of security changes.”

The round was described by Exaforce as one of the largest ever in the emerging AI security operations center market and comes just over a year after Exaforce raised $75 million Series A. Including the new round today, the company has now raised $200 million in funding.
