Endpoint security has a new problem: the endpoint itself is no longer a single device but a swirling ecosystem of AI agents, unknown extensions, and on-device data. Bloom Security just raised $20.0M in seed funding to build the control plane for that chaos.
The company’s pitch is that traditional endpoint tools were built for a pre-AI world, where the threat surface was files and processes. Bloom instead offers an end-to-end platform-visibility, analysis, prevention, and response-unified for what it calls the "AI-native endpoint." The round’s backers weren’t disclosed, but the size of a seed at this stage signals serious conviction that the security market’s next battleground is the software that runs alongside your AI agents, not just the ones you install yourself.
