In a bold move that challenges long-standing cybersecurity norms, Act Security, an Israeli startup, has emerged from stealth with a $60 million funding round. The company’s core premise is both provocative and timely: in the age of AI, traditional patching methods are no longer sufficient to protect against evolving threats. This argument has been largely ignored by the cybersecurity industry for decades, but Act Security is betting that the future of security lies not in fixing vulnerabilities after they’re discovered, but in preventing them in the first place.
Reimagining Security in the AI Era
The company was founded in 2025 by the team behind Medigate, which was acquired by Claroty in a move that signaled the growing importance of AI-driven security solutions. Act Security’s approach centers on cloud access AI agents—intelligent systems designed to monitor and manage access to cloud environments in real time. By leveraging AI to detect and neutralize threats before they can exploit system weaknesses, the startup aims to shift the security paradigm from reactive to proactive.
Why Patching Isn’t Enough
As cyber threats become increasingly sophisticated, the traditional model of identifying vulnerabilities and then patching them is proving inadequate. With AI-powered attacks capable of exploiting flaws in milliseconds, the window for traditional response mechanisms is shrinking. Act Security’s solution is to embed intelligence directly into access control systems, enabling them to adapt and respond to threats in real time. This approach aligns with a broader industry trend toward zero-trust architecture and AI-driven threat detection, but Act Security is pushing the envelope by integrating AI agents at the access layer itself.
What’s Next for Act Security
The company’s leadership believes that the next evolution in cybersecurity will be defined by systems that don’t just react to threats, but anticipate them. With $60 million in funding, Act Security is poised to disrupt the market by offering a new model for securing cloud environments. As AI continues to reshape the digital landscape, the startup’s strategy may well become the industry standard, challenging legacy security models that have dominated the field for years.
