Agentic security operations startup Exaforce has secured $125 million in Series B funding at a reported $725 million valuation to scale its AI-driven threat detection and reasoning platform.

Key Points

• Exaforce raised $125 million in a Series B round led by investors including HarbourVest Partners, Peak XV Partners, and Khosla Ventures.
• The company’s platform utilizes a real-time security knowledge graph and autonomous "Exabots" to correlate data during ingestion rather than during investigation.
• The architecture aims to reduce investigation times to under one minute, representing a tenfold improvement over traditional query-based security tools.
• Founded in 2023, the startup has grown to over 130 employees and has now raised a total of $200 million in venture capital.
• New funding will support multi-model AI development and international expansion into markets including Japan and Europe.

Why it Matters

This funding highlights the growing investor appetite for agentic AI solutions that aim to reduce the operational costs and manual labor associated with enterprise cybersecurity. By shifting from reactive querying to proactive knowledge graphs, Exaforce seeks to fundamentally change the economics of defense for security operations centers.
