1stProtect, founded in 2025 and based in San Francisco, builds the SIGMA engine, which enforces security policy directly at the operating-system level in real time, blocking credential theft, ransomware behavior, and data exfiltration rather than relying on cloud-based detection and response after the fact.
It runs entirely in user space with reported sub-millisecond latency and under 1% CPU overhead, aimed at high-frequency trading and AI training clusters where traditional agents are too heavy. Its founders are CrowdStrike, Symantec, and Cisco veterans; the performance figures are vendor-reported.
Innovation Matrix Assessment
Emerged from stealth with $20M in funding (announced March 2026) from Andra Capital and All Blue Capital shortly after 2025 founding.
Formally launched its platform at RSAC 2026; named enterprise deployments were not identified in coverage reviewed.
Public RSAC 2026 launch alongside the funding announcement targeting North America, Europe, and parts of Asia.
OS-level, user-space runtime enforcement with sub-millisecond latency is a meaningfully different architecture from typical cloud-dependent EDR agents.
Performance figures (latency, CPU overhead) are vendor-published; no independent third-party benchmark was located.
Real-time prevention of credential theft, ransomware, and data exfiltration addresses core, persistent enterprise threats.
Why CISOs Should Care
1stProtect's SIGMA engine enforces security policy directly at the operating-system level in real time -- blocking credential theft, ransomware behavior, and data exfiltration -- rather than relying on cloud-based detection and response after the fact.
What Makes It Different
Runs runtime enforcement entirely in user space with reported sub-millisecond latency and under 1% CPU overhead, positioning it for high-frequency trading and AI training cluster environments where traditional endpoint agents are too heavy.
The Matrix Verdict
42/100 — EMERGING / UNRANKED
Experienced founding team (CrowdStrike, Symantec, Cisco veterans) building a performance-focused runtime enforcement engine; early-stage with vendor-reported performance figures still to be independently validated.
Editorial Note: Claims vs. Verified Findings
Funding and founder-background claims verified via SecurityWeek and PR Newswire. Latency (<0.04ms) and CPU overhead (<1%) figures are vendor-published benchmarks.
