About Prelude
Prelude Security is building the category leader in Runtime Memory Protection — an endpoint product that detects and blocks in-memory execution, memory zero-day exploitation, and ransomware execution entirely from user mode.

Backed by Sequoia Capital, Insight Partners, and other leading investors, we are building an advanced security solution to detect in-memory attacks on endpoints.
