Prelude Security is a New York City-based endpoint security company that builds software to monitor customers’ existing controls—such as EDR and antivirus—and validate their coverage and configuration. Its platform operates entirely in user mode and now adds runtime memory protection, giving organizations an additional layer of defense against modern attack techniques. By combining continuous control monitoring with an on-device memory-protection agent, Prelude aims to strengthen resilience against commodity malware without requiring kernel-level installations. The company plans to use its latest capital to commercialize the runtime memory-protection capability, expand platform support, and accelerate customer deployments. Prelude has raised a total of $45 million to date, underscoring strong investor confidence despite no public disclosure of revenue or user counts.
