What is CrowdStrike? FAQ | CrowdStrike (2024)

Falcon is the CrowdStrike platform purpose-built to stop breaches via a unified set of cloud-delivered technologies that prevent all types of attacks — including malware and much more. Today’s sophisticated attackers are going “beyond malware” to breach organizations, increasingly relying on exploits, zero days, and hard-to-detect methods such as credential theft and tools that are already part of the victim’s environment or operating system, such as PowerShell. CrowdStrike Falcon® responds to those challenges with a powerful yet lightweight solution that unifies next-generation antivirus (NGAV), endpoint detection and response (EDR), cyber threat intelligence,managed threat hunting capabilities and security hygiene — all contained in a tiny, single, lightweight sensor that is cloud-managed and delivered.

Yes, CrowdStrike’s US commercial cloud is compliant with Service Organization Control 2 standards and provides its Falcon customers with an SOC 2®️ report. Additional information on CrowdStrike certifications can be found on our Compliance and Certifications page.

All data transmitted from the sensor to the cloud is protected in an SSL/TLS-encrypted tunnel. On average, each sensor transmits about 5-8 MBs/day.

CrowdStrike Falcon® is designed to maximize customer visibility into real-time and historical endpoint security events by gathering event data needed to identify, understand and respond to attacks — but nothing more. This default set of system events focused on process execution is continually monitored for suspicious activity. When such activity is detected, additional data collection activities are initiated to better understand the situation and enable a timely response to the event, as needed or desired. Note that the specific data collected changes as we advance our capabilities and in response to changes in the threat landscape. Information related to activity on the endpoint is gathered via the Falcon sensor and made available to the customer via the secure Falcon web management console.

Yes, CrowdStrike recognizes that organizations must meet a wide range of compliance and policy requirements. In order to meet the needs of all types of organizations, CrowdStrike offers customers multiple data residency options. Contact CrowdStrike for more information about which cloud is best for your organization.

All data sent from the CrowdStrike Falcon® sensor is tagged with unique, anonymous identifier values. Data and identifiers are always stored separately. Once in our cloud, the data is heavily protected with strict data privacy and access control policies. All data access within the system is managed through constrained APIs that require a customer-specific token to access only that customer’s data. Our analysis engines act on the raw event data, and only leverage the anonymized identifier values for clustering of results.

While other security solutions rely solely on Indicators of Compromise (IOCs) — such as known malware signatures, hashes, domains, IPs and other clues left behind after a breach — CrowdStrike also can detect live Indicators of Attack (IOAs), identifying adversarial activity and behaviors across the entire attack timeline, all in real time. Falcon’s unique ability to detect IOAs allows you to stop attacks

For known threats, Falcon provides cloud-based antivirus and IOC detection capabilities. For unknown and zero-day threats, Falcon applies IOA detection, using machine learning techniques to build predictive models that can detect never-before-seen malicious activities with high accuracy. Driven by the CrowdStrike Threat Graph™ data model, this IOA analysis recognizes behavioral patterns to detect new attacks, whether they use malware or not. The range and capability of Falcon’s detection techniques far surpass other security solutions on the market, particularly with regard to unknown and previously undetectable emerging threats.

Yes, Falcon includes a feature called the Machine Learning Slider, that offers several options to control thresholds for machine learning. In addition, this unique feature allows users to set up independent thresholds for detection and prevention.
