Cybersecurity startup Exaforce has raised $125 million in one of the largest fundings in the emerging AI-SOC (security operations centre) space, as enterprises look to counter AI-powered cyberattacks.
The round saw participation from HarbourVest, Peak XV, Mayfield, Khosla Ventures, Seligman Ventures, and AICONIC. This comes just a year after its $75 million raise and takes the company’s total funding to $200 million.
The Bay Area-headquartered company said the fresh capital will be used to scale its security operations platform, improve its real-time reasoning capabilities, and expand globally, including in Japan and Europe.
“We built Exaforce to be the platform defenders actually work in, not just an AI layer on top of existing tools,” said Ankur Singla, chief executive of Exaforce. “It starts with a real-time knowledge graph that gives agents complete context from the start, and extends into rich investigation and visualisation experiences that put security engineers and AI agents on the same page.”
The company is betting on what it calls a “real-time security knowledge graph”, which correlates identities, permissions, files, cloud activity, and security events. The company said it doesn't reconstruct the context later during investigations.
Exaforce said this architecture allows its AI agents to complete investigations in under a minute, reducing time and token consumption compared with conventional AI-SOC tools that rely on repeated queries across fragmented systems.
“The biggest opportunity in enterprise security is flipping the economics, so that defenders, not attackers, hold the leverage,” said Vinod Khosla. “When the cost of defence drops by an order of magnitude, the entire calculus of security changes,” he added.
The company said it has grown to more than 130 employees over the past year and processed millions of investigations across enterprise customers in sectors such as healthcare, financial services, and technology.
Customers like Guardant Health and Invisible are using the platform for threat detection, investigation, and response workflows.
“As a biotech company, safeguarding highly sensitive data is a constant priority, especially in a landscape shaped by faster, AI-driven attacks,” said Steve Mancini, chief security officer at Guardant. “With Exaforce's Exabots, we've accelerated detection, threat hunting, response, and investigations while expanding coverage without adding headcount.”
The startup competes with AI-native startups such as Dropzone AI, Prophet Security, 7ai, and established security players such as Palo Alto Networks and CrowdStrike.
