Exaforce raises $125 million Series B to combat AI-powered cyber threats with real-time detection

Exaforce Secures $125 Million Series B Funding to Scale AI Security Platform

Exaforce has closed a $125 million Series B funding round, marking one of the largest investments in the emerging AI security operations center market. The round valued the three-year-old agentic SOC startup at $725 million and attracted participation from HarbourVest, Peak XV, Mayfield, Khosla Ventures, Seligman Ventures, and AICONIC1

. Coming just one year after its $75 million Series A, the new capital brings Exaforce's total funding to $200 million, underscoring both the high cost of building AI-enabled cybersecurity solutions and the massive market opportunity investors see as AI for cyberattacks becomes increasingly sophisticated1

How Exaforce's AI-Native Security Operations Platform Works

Exaforce has built what it calls an agentic security operations platform that fundamentally differs from conventional AI-enabled security information and event management tools. The company uses AI agents called Exabots powered by a real-time knowledge graph that connects security events, identities, permissions, configurations, code, files, and cloud activity as they arrive2

. According to CEO Ankur Singla, the mission is straightforward: "Apply AI to catch and stop threats as they happen," though he acknowledges it's "very complex to execute"1

. While most AI SOC triage tools force agents to reconstruct context during security investigations by querying logs and calling APIs—sometimes requiring hundreds of queries per investigation—Exaforce builds and maintains its security knowledge graph at ingest, allowing its agents to answer investigative questions in under a minute, a 10x reduction in time and a significant reduction in tokens per investigation2

Real-Time Security Reasoning Tackles False Positives and AI-Powered Cyber Threats

The real challenge for security teams is that the vast majority of threat alerts are false positives. Umesh Padval, a managing partner at Seligman Ventures, compared the work of security teams to looking for a needle in a haystack, noting that "a security operations person gets hundreds of alerts"1

. Exaforce claims its AI security platform can reduce manual, time-consuming tasks by as much as 90%1

1

. The architecture improves threat reasoning quality because every event is chained to its identity and every resource is linked to its readers, writers, and permissions, meaning agents follow real relationships rather than inferring them on demand from fragmented logs2

2

. The company recently introduced vibe hunting, a feature that lets security teams query its platform with natural language to investigate potential attacks based on simple hunches. "With vibe hunting, you can ask a very simple hypothesis like, 'Did we get any new attacks from Iran?'" Singla explained1

Customer Momentum and Market Expansion Plans

Exaforce officially brought its product to market in the fourth quarter of last year, following two years of testing with design partners. The startup has since added 20 customers, including notable names like Replit and Guardant Health, and expects to reach 40 to 50 customers by year's end due to the rise in cyberattacks1

1

. In the past year, the company grew to over 130 employees and processed millions of investigations across its growing customer base2

2

. Patrick McKinney, Vice President of Security at Invisible, noted that Exaforce "feels less like a vendor and more like a true security partner," highlighting the platform's ability to unlock the full value of security data from enriched event ingestion to detection, response, and automation2

. The Series B funding will help Exaforce advance its core platform, including multi-model AI development, and expand its go-to-market presence in Japan and Europe3

Investor Conviction in Flipping Security Economics

Vinod Khosla, founder of Khosla Ventures, articulated the broader vision behind the investment: "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"2

2

. High-profile attacks have "supercharged our ability to get to customers, because the customers now don't ask, 'why do I need this?'" Singla said, adding that the question he hears more often now is "How do I operationalize it?"1

. The global expansion into Japan and Europe signals Exaforce's intent to address the worldwide demand for real-time security reasoning capabilities as AI-driven attack methods accelerate and zero-day threats proliferate2
