  "account": "AI security firm HiddenLayer has secured $100 million in Series B funding to bolster its platform. Led by Delta-v Capital, participating investors include Ten Eleven Ventures, Morgan Stanley, M12, and Booz Allen Ventures. This funding comes after a surge in demand for AI security solutions. HiddenLayer's annual recurring revenue surged tenfold within a year, accompanied by the addition of over 50 platform customers spanning finance, healthcare, government, technology, and defense sectors.\n\nThe company's platform safeguards AI applications throughout their lifecycle, addressing new security challenges posed by agentic AI systems. These autonomous agents, capable of making decisions and interacting with external tools, introduce fresh vulnerabilities. HiddenLayer's Agentic Runtime Security and Agent Harness Security solutions provide visibility into AI behavior during production, detecting manipulation, tool misuse, and unauthorized actions.\n\nTraditional security measures fall short in addressing these threats, which include poisoned models, malicious inputs, and prompt injection. To tackle these issues, HiddenLayer focuses on AI-specific security, combining discovery, attack simulation, supply chain protection, and runtime security. The company's research team boasts 39 granted patents and 65 pending patents, covering adversarial detection, model protection, and AI threat analysis. Their Adversarial Prompt Engineering Taxonomy further helps identify vulnerabilities across the AI ecosystem.\n\nHiddenLayer contributes to industry initiatives like CISA, MITRE, NIST, OWASP, and OpenSSF to enhance AI red teaming and security practices. The new funding will fuel the company's expansion into Europe and the EMEA region, where enterprise demand for AI security is expected to grow. Mike Gesnaldo has been appointed as the new chief revenue officer, and the company plans to reinforce channel partnerships while expanding internationally.",
