Forward Deployed Engineer at Prelude. Remote Location: United States. 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. We are a small team of security researchers and software developers working to reinvent the way we protect endpoints in a world where threats are complex, emergent, and accelerating. Backed by Sequoia Capital, Insight Partners, and other leading investors, we are building an advanced security solution to detect in-memory attacks on endpoints.. We are a small team of security researchers and software developers working to reinvent the way we protect endpoints in a world where threats are complex, emergent, and accelerating. Backed by Sequoia Capital, Insight Partners, and other leading investors, we are building an advanced security solution to detect in-memory attacks on endpoints, which is written in Rust and runs exclusively in user mode. It leverages advances in modern edge computing architecture, hardware-level telemetry, and a graph-based understanding of the Windows operating system to catch adversaries the moment that they compromise an endpoint. Rather than endlessly attempting to predict what an adversary might do, trapping adversaries at this universal and unavoidable chokepoint that lies at the center of their operations allows us to focus all of our efforts on what they must do, regardless of their sophistication or how much creativity (or AI) they apply to their tactics.. Our goal is simple: to detect out-of-context execution in a way that remains entirely outside the adversary’s control. Out-of-context execution occurs when an attacker coerces an application to run code paths that were not intended by the original application. This includes in-memory execution techniques such as local and remote injection, exploitation that results in the execution of dynamic code, and fileless malware. Role.
