HiddenLayer, an Austin-based AI security company, has just announced a $100 million Series B funding round, bringing its total raised to over $155 million. This significant investment will be used to expand the company’s platform and protect enterprises from evolving threats in the rapidly growing field of artificial intelligence (AI).
At the heart of HiddenLayer’s mission is the protection of AI agents, which are software programs that can perform tasks independently, often with little human oversight. These agents are increasingly being used by companies to automate business processes, but they also introduce new security risks. As Chris Sestito, co-founder and CEO of HiddenLayer, explained, “We set out to pioneer trusted, secure use of AI for enterprises, long before most organizations saw the urgency we do today.” With this funding, HiddenLayer plans to invest in agentic runtime security capabilities that cover AI coding agents, providing visibility into how these agents act in production and stopping anomalous behavior.
The company’s platform offers a range of features designed to secure the lifecycle of AI applications, including discovery, AI supply chain security, attack simulation, and runtime protection. This comprehensive approach ensures compliance, safe AI adoption, and intellectual property protection for enterprises. HiddenLayer’s goal is to provide end-to-end AI-native security that can continuously test and prove trust in AI.
The new funding round was led by Delta-v Capital, with additional support from prominent investors such as Booz Allen Ventures, Microsoft’s Venture Fund M12, Morgan Stanley, and Ten Eleven Ventures. This significant investment demonstrates the growing recognition of the importance of AI security and HiddenLayer’s position at the forefront of this field.
As AI continues to transform industries and businesses, it is becoming increasingly clear that traditional security measures are not sufficient to protect against emerging threats. HiddenLayer’s innovative approach to AI security addresses these challenges head-on, providing a much-needed solution for enterprises looking to harness the power of AI while minimizing risks.
For those concerned about AI security, this development serves as a timely reminder of the importance of investing in robust security solutions that can adapt to the evolving landscape of AI-powered threats. As HiddenLayer’s platform expands and becomes more comprehensive, it is likely to set a new standard for AI security, providing a safe and trusted environment for enterprises to deploy AI agents.
In practical terms, this means that companies should prioritize AI security as an essential component of their overall cybersecurity strategy. This may involve conducting thorough risk assessments, implementing robust security measures, and staying up-to-date with the latest developments in AI security. By doing so, organizations can minimize the risks associated with AI adoption and ensure a secure future for their businesses.
