Our company

Bringing active security intelligence, everywhere.

Prelude is a technology company that helps organizations proactively ask questions of their security systems to advance their defenses. Built around the notion of visibility, our products conduct continuous probing that elicits answers to questions that range from basic health checks to vulnerability to latest threats - across all environments.

By translating obscure definitions of security into concrete questions, Prelude provides holistic internal intelligence with which customers can identify, prioritize and take action seamlessly without any unknowns.
