AI security startup 7AI secures 187.2 billion KRW in Series A funding... Threat response time reduced by 90%

Cybersecurity startup 7AI has successfully raised $130 million (approximately 187.2 billion KRW) in a Series A round to upgrade its AI-based threat detection technology. The round was led by Index Ventures, with participation from Blackstone Innovations Investments, Greylock, CRV, Spark, and others. These investors, who also took part in 7AI’s $36 million seed round last June, have reinvested, reflecting high expectations for the company.

Headquartered in Boston, USA, 7AI provides a cybersecurity platform based on AI agents. The platform consists of over 40 AI agents, each responsible for different roles such as vulnerability detection, malicious behavior analysis, threat response, and device diagnostics. It analyzes data automatically based on integrations with existing security solutions, without requiring administrators to collect and transfer data separately.

Additionally, the platform visualizes issues as a to-do list in card form, prioritizes them based on threat severity, and describes each incident in natural language. For example, when a phishing email containing a malicious link is detected, it summarizes the relevant details and assists in taking appropriate countermeasures. Users can also issue commands for further actions. The platform also includes features for comparing suspicious malware files with a database or analyzing suspicious file behavior.

Enterprise customers can set their own security rules and create exceptions for specific users or departments. A paid premium version, “7AI Platform + PLAID,” is also available, which includes professional services. This product supports customized integrations for security tools that do not have general API integration.

According to 7AI, their platform can reduce the average investigation time for cybersecurity incidents by 30 minutes to 2.5 hours and can filter out up to 99% of false positives. This helps security leaders avoid being overwhelmed by a surge of notifications and alerts, enabling them to respond quickly to real attacks.

CEO Lior Div emphasized: “Threats are growing exponentially, and there are limits to how many alerts humans can handle. Our AI agents can process tasks faster, more accurately, and more consistently than humans.” With this round of funding, 7AI plans to focus on expanding its AI engineering team and sales team for customer acquisition.

This investment demonstrates that the emerging trend of “agent-based security” is drawing attention from both investors and the market. As AI shifts from being a mere alerting tool to an active response partner, 7AI has laid the foundation to take the lead at the forefront of this trend.
