CAPABILITIES

What does CrowdStrike Falcon do?

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 protection and response (EDR), managed threat hunting capabilities and security hygiene — all contained in a tiny 20MB sensor that is cloud-managed and delivered.

The Falcon web-based management console provides an intuitive and informative view of your complete environment.

Does the Falcon sensor interfere with other endpoint software?

No, Falcon was designed to interoperate without obstructing other endpoint security solutions, including third-party AV and malware detection systems.

How do I integrate with the Falcon Platform?

Falcon Connect has been created to fully leverage the power of Falcon Platform. Falcon Connect provides the APIs, resources and tools needed by customers and partners to develop, integrate and extend the use of the Falcon Platform itself, and to provide interoperability with other security platforms and tools. Find out more about the Falcon APIs:Falcon Connect and APIs.

Does CrowdStrike Falcon integrate with my SIEM?

Yes, Falcon offers two points of integration with SIEM solutions:

  • Customers can import IOCs (Indicator of Compromise) from their SIEM into the Falcon Platform, using an API.
  • Customers can forward CrowdStrike Falcon events to their SIEM using the Falcon SIEM Connector. The Falcon SIEM Connector enables integration with most SIEM offerings, such as HP ArcSight, IBM QRadar, and Splunk. Additionally, the Falcon Streaming API is available to customers who wish to build their own custom integration.

DEPLOYMENT

How long does it take to get started with CrowdStrike Falcon?

Literally minutes — a lightweight sensor (<20MB) is deployed to your endpoints as you monitor and manage your environment via a web console. With CrowdStrike Falcon there are no controllers to be installed, configured, updated or maintained: there is no on-premises equipment.

Is the Falcon sensor another agent? Will it slow down my endpoints?

The Falcon sensor’s design makes it extremely lightweight (consuming 1% or less of CPU) and unobtrusive: there’s no UI, no pop-ups, no reboots, and all updates are performed silently and automatically.

CLOUD

Is CrowdStrike Falcon cloud-based or on-premises?

CrowdStrike Falcon is a 100 percent cloud-based solution, offering Security as a Service (SaaS) to customers. Falcon requires no servers or controllers to be installed, freeing you from the cost and hassle of managing, maintaining and updating on-premises software or equipment.

Is Falcon SOC2 compliant?

Yes,CrowdStrike is compliant with Service Organization Control 2 standards and provides its Falcon customers with an SOC 2® report. Additionally, we also are TRUSTe compliant.

How does the Falcon sensor talk to the cloud and how much data does it send?

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.

What data is sent to the CrowdStrike Cloud?

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.

How do you separate and safeguard data sent to your cloud?

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.

PROTECTION

What is an IOA?

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 attacksbeforea damaging breach occurs.

What detection capabilities does CrowdStrike Falcon have?

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.

Does Falcon provide malware prevention?

Falcon Prevent stops known and unknown malware by using an array of complementary methods:

  • Machine learning
  • Custom blocking (whitelisting and blacklisting)
  • Exploit blocking
  • IOA (Indicators of Attack) prevention
  • Additional protection specific to ransomware

Customers can control and configure all of the prevention capabilities of Falcon within the configuration interface.

Is Falcon’s machine learning feature configurable?

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.

Does Falcon Prevent protect against ransomware?

Falcon Prevent uses an array of complementary prevention and detection methods to protect against ransomware:

  • Blocking of known ransomware
  • Exploit blocking to stop the execution and spread of ransomware via unpatched vulnerabilities
  • Machine learning for detection of previously unknown “zero-day” ransomware
  • Indicators of Attack (IOAs) to identify and block additional unknown ransomware, as well as new categories of ransomware that do not use files to encrypt victims’ data

Can CrowdStrike Falcon detect in-memory attacks?

CrowdStrike Falcon is equally effective against attacks occurring on-disk or in-memory. The platform continuously watches for suspicious processes, events and activities, wherever they may occur.
