Additionally, sample scenarios are supported with MITRE mappings and application recommendations.

SentinelOne Singularity Platform Architecture and Security Components Link to heading

SentinelOne Singularity Platform offers a multi-layered security architecture, combining not only endpoint protection but also threat detection and response. The “single agent — multi-engine” architecture increases business efficiency by delivering all these security functions through a single agent. The lightweight SentinelOne agent runs at the operating system kernel level and monitors file system, process and memory activities in real time.

On this platform, two basic artificial intelligence engines, such as Static Artificial Intelligence (AI) engine and Behavioral Artificial Intelligence engine, work in an integrated manner. The static engine blocks threats in advance by evaluating the file’s structure and code properties without considering its signature or hash. The behavioral AI engine detects abnormal behavior by monitoring interactions such as inter-process relationships, API calls and network connections. These structures provide critical protection, especially against zero-day threats and unsigned attacks.

Autonomous Decision Capability: SentinelOne can make autonomous decisions to analyze and respond to threats. Agents can detect and block threats even without an internet connection. This is especially important for isolated networks or critical infrastructures.

Centralized Management Console and Scalability: SentinelOne’s centralized management console can be configured as cloud-based or on-premise. Thanks to its multi-tenant architecture, role-based access controls can be defined for different teams. Additionally, it has an elastic infrastructure that can manage more than 500,000 agents.

Threat Detection and In-Depth Visibility Link to heading

SentinelOne Singularity Platform provides comprehensive protection against known and advanced threats with a multi-layered threat detection architecture. This architecture analyzes files and processes in both phases:

  1. On-Write Static Analysis: Before the file is written to the disk, its structure and code features are evaluated and threats are prevented in advance.
  2. On-Execute Behavioral Analysis: When the file is executed, abnormal behavior is detected by monitoring transactions within the application, API calls, network connections and changes in the system.

This approach offers a critical advantage, especially for zero-day threats (0-day) and unsigned attacks. SentinelOne also allows security teams to perform deeper analysis by visualizing the contextual timeline of events with its Deep Visibility module.

Deep Visibility module transforms SentinelOne from a classic prevention tool into a full-fledged security operations platform that enables contextual understanding of events and rapid response.

MITRE ATT&CK Mappings and Storyline Technology: SentinelOne is directly related to the MITRE ATT&CK framework and threats are visualized in the context of the timeline. Storyline technology allows analysts to review events more quickly and accurately by tagging each event with a “Storyline ID.”

Incident Response and Security Automation Link to heading

SentinelOne provides advanced incident response and security automation for fast and accurate response to cyber threats. These features ensure that threats are quickly neutralized and installations are easily rolled back.

Isolate Device: When critical threats are detected, the device is isolated from the network, providing access only to the management console. This prevents lateral movement and data exfiltration attempts.

Agents; It constantly records events such as processes, file operations, network connections, sessions and memory activities. This data is stored for 14–90 days depending on the license package and can be analyzed with SentinelOne’s simplified query language S1QL. Thanks to this language, which does not require technical knowledge, processes that have run the “net user” command in the last 180 days can be easily listed, for example:

SELECT Timestamp, DeviceName, ProcessName, CommandLine  
FROM ProcessActivities  
WHERE LOWER(CommandLine) LIKE '%net user%' AND Timestamp > NOW()-180d;

1-Click Remediation & Rollback: After threats such as ransomware, files and system settings can be quickly restored. The platform stores file versions prior to the attack, ensuring secure retrieval of data immediately after the threat.

The Automation / RemoteOps tab on the console allows running batch or scheduled commands on endpoints at the time of an incident or during routine operations. For example, operations such as service shutdown, log collection, or memory dumping for forensic analysis can be applied to hundreds of devices simultaneously.

Additionally, thanks to API-based integrations, SentinelOne can trigger automatic actions with other security and IT systems. For example, when a SIEM rule detects a suspicious account lockout, SentinelOne can find and automatically isolate the devices to which that account is connected via the API.

Policy Management and Security Configuration Link to heading

SentinelOne offers policies that can be customized according to the different needs of organizations. These policies provide granular controls over devices and network segments, allowing different security levels to be defined. Policies can operate in two main modes:

  • Detect-Only: In this mode, threats are detected but not intervened. Only warning is generated.
  • Protect: Threats are detected and blocked automatically.

The main types of policies that can be defined in the SentinelOne console are:

  • Threat Protection: Static and behavioral AI thresholds, automatic response behaviors.
  • Device & Firewall Control: Blocking USB devices, port-based access restrictions.
  • Network Control (Ranger): Agents detect devices that do not have agents installed by reconnaissance in network segments.
  • Exclusions: File, directory or hash based exception definitions. This area should be used with caution; Excessive exception definitions can create security blind spots.

Policies can be governed by hierarchical inheritance; Rules defined at the top level can be customized in subgroups. It can also be exported and version controlled in JSON format, making it easy to track and roll back changes.

Licensing, Packages and Deployment Options Link to heading

SentinelOne offers a flexible licensing model based on corporate needs. Different packages can be configured according to the scale and security requirements of organizations:

  • Core: Basic NGAV and limited EDR features.
  • Control: Includes management capabilities such as device and network control (USB, firewall).
