CrowdStrike Signal Delivers the Next Evolution of AI-Powered Threat Detection

Now GA, new self-learning detection engines surface threats undetectable for others 鈥� connecting subtle activity into prioritized leads to accelerate investigation, hunting, and response

AUSTIN, Texas--(BUSINESS WIRE)-- Black Hat USA 2025, Las Vegas -- (NASDAQ: CRWD) today announced the general availability of CrowdStrike Signal, a new class of AI-powered detection engines that surface the undetectable threats others miss 鈥� before they escalate. Signal uses self-learning models for every host to understand what鈥檚 normal in that environment across time, systems, and users. It pinpoints subtle, early-stage threat activity and connects related behaviors 鈥� before traditional tools act. By identifying weak signals that deviate from the norm and building high-confidence, prioritized leads, Signal accelerates the Falcon庐 platform鈥檚 AI advantage and empowers security teams to investigate, hunt, and stop threats earlier in the kill chain.

Modern attacks often begin with low-signal activity that appears benign in isolation. Traditional rule-based systems ignore these behaviors because they lack the context to tell what鈥檚 suspicious and what鈥檚 just noise. Even newer AI approaches apply scoring only after a detection has occurred.

Signal learns what鈥檚 normal across the environment and continuously updates its understanding of standard activity as conditions change 鈥� identifying what deviates and linking early-stage behaviors with downstream activity. By analyzing behavior earlier in the threat lifecycle and correlating subtle activity across time, CrowdStrike turns fragmented signals into a small number of prioritized, AI-generated leads that expose threats buried in the noise and jumpstart response. Born on the endpoint, Signal lays the foundation for next-generation detection across identity, cloud, and third-party data.

鈥淐rowdStrike pioneered AI-native cybersecurity, and continues to deliver the innovation driving the industry forward. Signal is our latest breakthrough, built to detect how modern adversaries actually operate,鈥� said Elia Zaitsev, chief technology officer, CrowdStrike. 鈥淭oday鈥檚 attackers spread subtle signals over time to stay under the radar. Signal is designed to catch what others overlook, connecting the dots across systems and time to paint the full picture.鈥�

Signal Through the Noise
Behind Signal is a new family of statistical time series models that analyze billions of daily events within each customer鈥檚 environment. By linking signals across time and systems, Signal filters out repetitive activity and surfaces what鈥檚 truly unusual. This correlation builds high-confidence patterns that reveal stealthy attacker behavior before others can, giving defenders a clear starting point to act.

• Self-learning AI to Understand the Customer Environment: Signal continuously models behavior for each user, host, and process, adapting over time to surface meaningful deviations. Unlike static rules or pre-trained models, it delivers early-stage detection without manual configuration or constant adjustment.
• AG真人官方-time Detection of Stealthy Tradecraft Others Miss: Signal links subtle behaviors often used by attackers 鈥� but also commonly seen on benign hosts 鈥� such as the use of living-off-the-land tools for reconnaissance or applications running from temporary directories. This low-signal activity may appear benign in isolation, but analyzed earlier, over time and context, it reveals attacker activity that would otherwise go unnoticed.
• High-confidence Leads Reduce Alert Volume, Accelerate Response: Signal condenses a vast number of behaviors and detections into a small set of high-fidelity leads. It surfaces early indicators of compromise, reduces false positives, and groups related activity into a single starting point to eliminate manual triage and speed investigation, hunting, and response.
