Onyx Security Raises $113 Million in Series B Funding
Onyx Security has announced a significant milestone, securing $113 million in a Series B funding round. The round was led by Bessemer Venture Partners, with participation from Cyberstarts, TCV, Conviction, FirstMark, Vintage, QuantumLight, and G Squared. This funding aims to bolster Onyx's capabilities in overseeing and securing AI agents across enterprises.
Company Overview
Onyx Security specializes in managing AI agents within enterprise environments. The company provides a platform that not only ensures the security and compliance of these AI systems but also measures their effectiveness. This is increasingly important as enterprises adopt more sophisticated AI technologies that require robust oversight.
Leadership and Vision
Founded by Gil Elbaz, who serves as the Chief AI Officer, and Maxim Bar Kogan, the CEO, Onyx Security is at the forefront of AI management. Bar Kogan noted the growing role of AI agents, stating, "In 2025, less than one percent of actions were made by agents. These new autonomous actors will soon be taking the overwhelming majority of actions, which begs the question – how do we guarantee these actions are legitimate?"
Strategic Use of Funds
The newly acquired capital will primarily be allocated to training the next generation of Onyx's proprietary models. Additionally, the company plans to scale its go-to-market efforts in the United States and potentially expand internationally. This aligns with their strategy to cater to a broader range of industries, including banking, technology, insurance, and energy.
Market Impact and Future Prospects
Onyx Security has experienced rapid growth, quadrupling its revenue since emerging from stealth mode just four months ago. The company's platform is integrated with multiple AI providers, including a recent partnership with Anthropic to secure enterprise AI adoption. Onyx's solutions are already trusted by numerous Fortune 500 companies, highlighting its significant impact on the market.
As enterprises increasingly rely on AI, the need for platforms like Onyx's that ensure AI actions are secure and compliant becomes vital. With the fresh influx of capital, Onyx Security is well-positioned to expand its influence and continue providing essential AI oversight solutions.
