SentinelOne Singularity platform demo covering alert triage, investigation, threat hunting, and remediation using AI-assisted endpoint and cloud defense.

Open alerts are accessible from the left side menu. Selecting a ransomware alert for GPAgentInstaller.exe shows a natural language summary generated by Purple AI. Static AI identifies a ransomware file on user JeanLuc's desktop. The Graph view displays related entities, alerts, and misconfigurations, revealing that the endpoint TheBorg has multiple related alerts including a Lateral Movement alert. Purple AI summarizes the Lateral Movement alert, noting suspicious file manipulation, execution of malicious shellcode, and correlation to multiple MITRE ATT&CK indicators with severity tags.

The Storyline view organizes all atomic endpoint events into a single narrative describing the full chain of events on an endpoint. Nodes in Storyline can be expanded to show details such as command line arguments and network connections. Alert details include the detection engine that generated the alert, first-seen and last-updated timestamps, and an Alert Footprint showing how many times the malware has been seen across the organization. In this case the malware was first seen in 2024 and has impacted over 2,600 machines.

Singularity Threat Intelligence, an optional add-on, integrates Google Threat Intelligence context. Over 8,000 events were scanned with potential indicators found at 100 risk scores. The RACCOON malware family is identified as data-mining malware targeting Windows, with associated malware families and targeted industries listed. Searching for RACCOON indicators by hash in the Singularity Data Lake returns over 6,700 matching records including behavior indicators, network actions, and registry changes. Purple AI analyzes event properties and generates a summary identifying 9 defense evasion indicators.

Purple AI includes Quick Starts with pre-populated threat hunts and common support questions. Purple AI for Support is an always-on agent trained on SentinelOne technical documentation to answer administration questions. Selecting a hunt for MITRE ATT&CK T1140 (Deobfuscate/Decode Files), Purple AI automatically translates natural language into structured PowerQueries. The query returns 48 matching results in the Singularity Data Lake within the last 72 hours. Purple AI summarizes a selected event, identifying obfuscated PowerShell commands used to execute malicious code while evading detection. Purple AI also provides follow-up question recommendations to continue the hunt. A follow-up query for common T1140 indicators returns 4 results, the most common being suspicious shellcode followed by the obfuscated PowerShell command. Purple AI can generate an email summary of the hunt and supports full multilingual translation for globally dispersed SOC teams. Hunt findings can be saved as a named Notebook and shared with team members for collaborative review.

For remediation, multiple mitigation options are available and can be automated via policy to reduce attacker dwell time. The Kill action stops all running processes associated with the threat. The Quarantine action encrypts and moves threat executables to prevent further infection. The Remediate action deletes all system and file changes including persistence mechanisms. SentinelOne's 1-click Rollback restores files and configurations altered by the attacker, including files encrypted during a ransomware event. Mitigation is applied within milliseconds. Singularity Hyperautomation extends mitigation to third-party tools via customizable automation workflows with over 100 pre-built integrations for SaaS applications.

Alerts can be grouped into Incidents, either automatically through built-in correlation or manually. Incidents provide a higher-level view of all related alerts within an attack campaign and include related artifacts, assets, and all observed MITRE ATT&CK tactics. Incident names are generated automatically upon creation.
