Announcing our research preview of Runtime Memory Protection (RMP)

Ensuring your endpoints are secure even when attacks are novel by default

Prelude is building the next-generation endpoint security platform, designed to monitor that existing defenses are performing as expected—and to catch the threats they can’t.

Platform

When 90% of successful cyberattacks start at the endpoint, something has to give

While there is no shortage of technology built to secure your environment, organizations still grapple with incidents caused by misconfigured tools. Worse yet, those tools aren’t built to detect modern adversaries. Until now.

Maximizing your security tools while minimizing your effort

Unmanaged devices present the best targets for ransomware attacks

Prelude makes it easy to find and fix these coverage gaps with continuous monitoring and validation of your existing security tools and assets, so you can do business with confidence.

The only code that should run on your endpoints is your own

Roughly 75% of all cyberattacks occur exclusively in-memory, never dropping a file to disk

Prelude has unveiled foundational research and technology purpose-built to comprehensively detect the execution of any malicious code on your endpoint devices—all in user mode.

Use cases

Securing your endpoints requires unparalleled visibility

Prelude provides essential, ongoing visibility into your existing tools and devices. From your best-of-breed vulnerability management platform to novel telemetry captured from the hardware of your workstations, Prelude sees it all—so you do too.

Quickly find and fix gaps in your security tools

Achieve ongoing visibility to surface critical gaps in your environment—from outdated vulnerability scans to missing EDR, and more.

Routinely manage your threat exposure

Continuously hone your tools against relevant threat intel, and validate those defenses are working with robust adversary emulation.

Catch adversaries the moment that they compromise an endpoint

Your existing defenses weren’t built to detect in-memory attacks. Comprehensively detect the presence of advanced adversaries, entirely from user mode.
