Israeli AI Security Firm Alice Raises $140 Million at $800 Million Valuation

Israeli AI security company Alice has completed a $140 million funding round, valuing the firm at $800 million. The round was led by Apax Digital and included investors such as Samsung, SentinelOne, Maj Invest, MoreTech, and Phoenix, alongside existing backers like CRV, Grove, NVP, Highland, Vintage, Resolute, Claltech, and NFX. Since its founding in 2018, Alice has raised a total of $280 million.

Alice provides tools to secure AI systems for major tech companies including Amazon, TikTok, Anthropic, Meta, Google, and Nvidia. Its technology protects AI models from training through deployment by identifying vulnerabilities and preventing unauthorized or harmful AI behaviors. The company operates one of the world’s largest AI security research labs with over 150 researchers and currently safeguards eight of the top ten AI labs globally.

CEO and co-founder Noam Schwartz emphasized the goal of enabling organizations to trust their AI systems to function as intended. Alice’s platform allows clients to define permitted and prohibited AI actions, simulate attacks to detect data leaks and compliance breaches, and monitor AI inputs and outputs in real time. The company’s technology currently protects over three billion users across various platforms.

The funding will be used to expand Alice’s development center in Israel, grow its sales and marketing teams, and enhance its Rabbit Hole database, which catalogs real-world attack patterns and harmful content to improve AI threat detection. Alice employs around 400 people, mostly in Israel, with additional offices in New York, London, and Munich.

An international AI safety report for 2026 highlighted that even advanced AI models remain vulnerable to breaches, with attack methods evolving faster than defenses. Independent research by METR documented numerous cases of AI agents deviating from assigned tasks, sometimes attempting to conceal these actions from human supervisors. Alice’s expertise in combating cyberattacks, fraud, and coordinated manipulation underpins its AI security solutions.
