Artemis Security, an Israeli startup focused on protecting artificial intelligence systems, has raised $70 million in a new funding round as investor interest intensifies around the security risks created by rapidly expanding AI deployments. The financing, first reported by Globes in an article titled “AI protection co Artemis Security raises $70m,” underscores a growing conviction in the market that safeguarding AI models and the infrastructure that supports them is becoming a strategic priority for enterprises and governments alike.
The company positions its technology as a defensive layer designed specifically for AI environments, where conventional cybersecurity tools can fall short. As organizations embed generative AI and machine-learning systems into customer service, software development, finance, and critical operations, they are encountering new classes of threats: adversarial inputs that manipulate model outputs, data poisoning that compromises training sets, prompt-injection attacks that exfiltrate sensitive information, and operational risks stemming from opaque model behavior. Security teams are also grappling with a widening attack surface as models are connected to proprietary databases, internal tools, and third-party applications.
Artemis’ fundraising arrives amid heightened scrutiny of AI governance and the security of model supply chains. Regulators in the United States and Europe have pushed for clearer accountability around AI systems, while corporate boards increasingly demand assurances that AI adoption will not introduce material legal, privacy, or business-continuity risks. The emerging “AI security” category includes not only protections against external attackers but also controls that aim to prevent internal misuse, ensure compliance, and provide auditability in environments where models can make consequential decisions.
In the Globes report, the scale of the round signals that investors are betting on specialist vendors rather than expecting incumbent cybersecurity platforms alone to address AI-specific vulnerabilities. The funding environment for cyber startups has been selective over the past two years, but AI-linked security has remained a bright spot, buoyed by the speed of enterprise adoption and the perception that defensive tooling is struggling to keep pace with model innovation.
The backing should help Artemis accelerate product development and expand its go-to-market efforts, as companies worldwide move from AI experimentation to production use and discover the practical challenges of deploying models safely. For many organizations, the question is no longer whether AI introduces new risks, but how quickly they can implement safeguards that match the technology’s impact. In that context, Artemis’ latest financing suggests that the market for AI-native security controls is shifting from early-stage curiosity to a competitive, well-capitalized race.
