Prelude Security, a next-generation endpoint protection company, has secured a fresh $16m investment led by Brightmind Partners, with participation from Sequoia Capital and Insight Partners. The new round brings its total funding to $45m.
This latest capital injection will be directed towards commercialising Prelude’s runtime memory protection technology, which identifies and halts malicious code at the moment of execution. The company also plans to expand its platform support and customer deployment to meet growing demand.
Cybersecurity experts note that around 75% of advanced attacks now operate entirely in memory, bypassing file and behaviour-based detection systems. Prelude’s runtime memory protection introduces hardware-level telemetry to detect out-of-context code execution in user mode. The technology complements Microsoft’s Windows Resiliency Initiative and promises a structural shift in endpoint defence.
In addition to this new capability, Prelude’s existing services monitor and validate endpoint defences such as EDR and antivirus tools, ensuring proper coverage and configuration against malware. Building on this, its user-mode agent provides an extra layer of defence against memory-resident techniques and ransomware.
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.”
