Cybersecurity startup NewCore has exited stealth following a $66 million seed round led by Cyberstarts, with additional participation from Index Ventures and Evolution Equity Partners, establishing a post-money valuation of $300 million. The initiative, co-founded by former Dome9 founder Zohar Alon, ex-Unit 8200 researcher Amihai Neiderman, and former T-Mobile USA CIO Erez Yarkoni, directly addresses a pressing enterprise security challenge: the scaling of artificial intelligence agents as functional workplace participants. As organizations increasingly integrate autonomous AI systems alongside human staff, legacy identity and access management frameworks are proving inadequate. Co-founder and CEO Alon emphasized that decades-old authentication architectures cannot accommodate the volume, complexity, and operational autonomy required for AI-driven workforces. NewCore's platform was engineered from the ground up to treat software agents as first-class identities rather than traditional machine credentials. The system provides centralized lifecycle management, granular permission controls, and automated revocation protocols within a unified environment. To mitigate systemic vulnerabilities, NewCore employs a proprietary split-key architecture that partitions critical authentication credentials between the enterprise and the platform, effectively eliminating single points of compromise. The solution also includes Agentic Skill integration packages compatible with major coding assistants, including Anthropic's Claude Code, OpenAI's Codex, and Cursor, enabling secure, managed network access without manual key distribution. A companion mobile application further establishes a human oversight layer, allowing personnel to approve, audit, and terminate agent permissions in real time. The funding announcement coincides with accelerating enterprise adoption of AI workers. Major firms such as Goldman Sachs and McKinsey have already deployed thousands of AI agents across their operations, while industry executives project that software-driven personnel could soon rival human headcounts in technology sectors. NewCore currently supports fewer than ten commercial clients and over ten design partners, with full monetization scheduled to commence this summer. The startup has expanded to more than fifty engineers and operations staff across the United States and Israel, positioning itself to address what leadership describes as an unavoidable inflection point in enterprise security infrastructure.
