Cloud security platform Echo raises $35M Series A, bringing funding to $50M in 10 months
Founded by serial entrepreneurs and former Unit 8200 veterans, Echo aims to replace standard cloud infrastructure with a streamlined, secure AI-native operating system, already deployed at leading organizations.
Cybersecurity company Echo, which develops secure AI-based software infrastructure, has raised $35 million in a Series A funding round led by N47 Fund, with participation from Notable Capital, Hyperwise Ventures, and SentinelOne. The financing comes just four months after a $15 million Seed round, bringing Echo’s total funding to $50 million less than a year after its founding.
Echo was founded in early 2025 by CEO Eilon Elhadad and CTO Eylam Milner, both veterans of Israel’s elite Unit 8200 and the Ofek intelligence unit, with more than a decade of experience in cybersecurity. The two previously founded Argon in 2020, which was acquired within a year by Aqua Security for $100 million.
The company says its software is already deployed across dozens of organizations, including Vectra AI, EDB, Port, UiPath, and Varonis. Echo has also integrated with a broad ecosystem of security partners, among them Wiz, Orca, Aqua, Mend, and Anchor. The company currently employs 35 people across Israel and New York and plans to use the new capital to expand its workforce, accelerate product development, and scale its commercial operations.
Echo is targeting a structural weakness in modern cloud environments. Most applications today are built on pre-packaged infrastructure components that often contain thousands of known vulnerabilities, exposing organizations to persistent security risks. Rather than repeatedly patching these inherited weaknesses, Echo takes a different approach: rebuilding software infrastructure from the ground up so that it includes only the components that are strictly necessary.
By eliminating unused elements and reducing the attack surface at the infrastructure level, Echo aims to create a fundamentally more secure environment that can replace existing industry standards. For developers, the transition is minimal, often requiring no more than a single line of configuration, yet it immediately alters the security posture of the application.
