What happened
Echo, a cloud security startup, raised $35 million in Series A funding led by N47 Fund, with participation from Notable Capital, Hyperwise Ventures, and SentinelOne. The round brings Echo’s total funding to $50 million less than a year after the company launched. Echo builds AI-native secure infrastructure designed to remove unnecessary cloud components and reduce exploitable vulnerabilities.
Who is affected
The platform is already in use by companies including Vectra AI, UiPath, Varonis, EDB, and Port. Cloud-native enterprises, SaaS providers, and security teams managing complex cloud environments are the primary audience for this type of infrastructure approach.
Why CISOs should care
Cloud environments often inherit services and components that expand the attack surface. Echo’s approach reflects a broader shift toward designing security into infrastructure from the start, rather than relying on patching and detection after deployment. For CISOs, this signals growing momentum around attack surface reduction as a core cloud security strategy.
3 practical actions
-
Review current cloud architectures to identify unused or high-risk components.
-
Evaluate infrastructure models that minimize default services and dependencies.
-
Work with engineering teams to align secure-by-design platforms with existing DevOps workflows.
