Prelude Security, the next generation endpoint protection platform, today announced an additional $16 million investment led by Brightmind Partners, with participation from existing investors Sequoia Capital and Insight Partners, bringing total funding to $45 million. Prelude will use the capital to commercialize runtime memory protection—technology that can detect and stop malicious code at execution—and to expand platform support and customer deployment.
Today’s security teams face an escalating challenge: approximately 75% of advanced cyberattacks now operate exclusively in-memory. These attacks evade traditional file and behavior-based detection methods highlighting the gap in today’s suite of endpoint security platforms. Prelude’s announcement of runtime memory protection fundamentally restructures endpoint protection by leveraging novel, hardware-level telemetry to detect out-of-context code execution, entirely in user mode. This aligns closely with Microsoft’s Windows Resiliency Initiative.

Prelude’s existing monitoring and validation capabilities help customers ensure the coverage and configuration of endpoint security tools like EDR and antivirus to strengthen resilience against commodity malware. Building off these capabilities, Prelude’s introduction of runtime memory protection via a user mode agent provides an innovative, robust layer of defense against the methods of a modern attacker to augment existing defenses.
These attackers increasingly exploit memory-resident techniques, process injection, and “living-off-the-land” tactics to bypass current endpoint security tools. Prelude’s capabilities focus on what attackers must do—execute code—making it possible to stop ransomware and hands-on-keyboard activity faster than current defensive tools.
Prelude Security is a next generation endpoint security company built to monitor existing controls and provide runtime memory protection, entirely in user mode. Backed by Sequoia Capital, Insight Partners, and other leading investors, Prelude is 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.
