Israeli Startup Act Security Raises $60M With "No Patching" Cybersecurity Approach
Israeli cybersecurity startup Act Security has emerged from stealth mode, securing $60 million in funding. The company argues that the traditional approach of patching vulnerabilities is no longer an effective strategy for ensuring security. Act Security launched on Tuesday, according to a report by Calcalist. The startup was founded in 2025 by the same team that previously sold Medigate to Claroty. Their core proposition challenges a long-held industry belief that continuous patching is the primary method for mitigating cyber threats. This new perspective suggests a fundamental shift in how organizations should approach cybersecurity in the face of evolving threats.
Act Security's strategy challenges the established paradigm of vulnerability management, proposing that continuous patching is an unsustainable defense against sophisticated threats. This approach may reflect a growing recognition of the limitations of reactive security measures in an era of rapid software development and zero-day exploits. The significant funding indicates investor confidence in this alternative model. The long-term viability of a 'no patching' strategy will depend on its ability to demonstrably reduce risk and operational overhead compared to traditional methods, potentially by focusing on exploit prevention or rapid, automated containment rather than just vulnerability remediation.
