Prelude Security, a company developing next-generation endpoint protection, has raised $16m in new funding led by Brightmind Partners, with Sequoia Capital and Insight Partners also joining. This takes its total funding to $45m.
The firm, based in the US, focuses on protecting systems from advanced cyberattacks that evade conventional tools. Its main product, runtime memory protection, detects and blocks malicious code as it executes.
The new funds will be used to commercialise this technology, expand platform support, and scale customer deployment.
Prelude argues that traditional endpoint tools are not designed to stop today’s threats, with about 75% of advanced attacks now operating entirely in memory. Its approach uses hardware-level telemetry to spot out-of-context code execution, aligning with Microsoft’s Windows Resiliency Initiative.
Prelude Security CEO Spencer Thompson said, “As we’ve worked with existing customers to monitor and validate their existing endpoint defenses, we’ve seen first-hand how attackers increasingly live in-memory and evade traditional EDR platforms. This investment enables us to expand and commercialize our ability to detect adversaries at the moment it matters—execution.”
Brightmind Partners general partner Stephen Ward said, “The shift to in-memory attacks represents a fundamental evolution in the threat landscape that traditional endpoint solutions simply weren’t architected to address.
“Prelude’s hardware-level telemetry approach tackles the core problem—attackers must execute code, and that’s exactly where this technology intercepts them. This isn’t incremental innovation; it’s an architectural leap in endpoint security and we believe it’s time for the next generation of endpoint protection and we think this is the team to build it.”
