Israeli AI security startup working on protecting AI models has raised $140 million in a funding round. It's one of the biggest investments yet in a niche that barely existed a few years ago.
The company builds tools meant to keep AI systems safe from attacks and misuse, an area that's turning into a priority as AI gets embedded in finance, healthcare, and other sensitive industries.
Why AI is suddenly a priority
The funding round is a strong sign that investors see AI security as a distinct problem from traditional cybersecurity. Standard defenses are built to protect networks and servers. AI models have their own weak spots: they can be tricked with subtle inputs, have their training data poisoned, or be coerced into leaking information. Those don't always fit the old playbook.
So a new wave of companies is building protections from scratch. The money flowing in suggests that this is no longer a side project for a few security researchers. It's becoming a core piece of how AI gets deployed.
What the money will go toward
The startup hasn't given a detailed roadmap for the $140 million. The focus, though, is clear: improve the security of AI models themselves. That includes spotting vulnerabilities before they're exploited, monitoring how a model behaves in the real world, and securing the data used to train it.
More engineers and bigger product offerings are likely on the list. The company is also joining a pack of other AI security firms that have pulled in funding over the last year. Investors are treating AI security as its own category, with its own tools and its own rules.
A shift in how cybersecurity works
The investment could change what cybersecurity looks like in practice. The old model is about putting walls around a system. AI security is different: the system itself is the target, and the threat can be the person using it. The model has to be built so it can't be tricked into doing something it wasn't meant to do.
That's a harder problem, and the startups working on it are still defining the standards. The $140 million is a bet that those standards will become part of the mainstream security landscape.
No timeline has been set for the company's next product announcements. The money itself, though, is a clear statement about where the industry is heading.
