What is our primary use case?
I use SentinelOne Singularity AI SIEM for security operations. An AI-powered SIEM uses machine learning, and for us, the primary value is reducing manual investigation effort while improving the detection of threats that traditional rule-based SIEMs may miss. SentinelOne Singularity AI SIEM has Purple AI for that purpose. Analysts can use natural language to investigate security data and generate queries. It also has unified security data analytics, which allows us to analyze endpoints, firewalls, identity, cloud, and third-party security logs from a common platform without switching between tools. If a potentially compromised employee account exists, a traditional SIEM may generate separate alerts for each event. However, SentinelOne Singularity AI SIEM can help correlate the events, summarize the investigation, and identify the relationship between them.
A particular example of my use is creating a detection rule. I used SentinelOne Singularity AI SIEM AI and machine capabilities to develop detection logic, generate a query, and ingest logs. Purple AI helped me build the detection logic, but I still validated and deployed the rule. I wanted to create a custom detection rule for external port scanning activity. I analyzed the available FortiGate firewall logs and identified the source IPs originating from external networks. I grouped events by source IP and destination IP, counted the unique destination ports scanned, and used Purple AI by entering a prompt regarding all of this. I reviewed the generated query and confirmed the fields that match with my FortiGate logs. I executed the query and adjusted the threshold, then created the scheduled detection rule using the validated query. I tested it and performed tuning as required.
I also use SentinelOne Singularity AI SIEM for rule and detection development. I developed detections for repetitive failed VPN login attempts. I analyzed gaps with Purple AI and detected data exfiltration using Purple AI.
How has it helped my organization?
SentinelOne Singularity AI SIEM has the potential to improve my organization's security operations by reducing manual investigation efforts, accelerating threat detection, and improving the efficiency of the SOC. Its AI-powered threat hunting and detection engineering capabilities help us develop better detection rules, identify security threats more effectively, and streamline incident response. This has led to improved operational efficiency and better utilization of our security analysts' time.
I have observed time savings in security investigations and detection rule development. AI-assisted techniques reduce the time spent manually writing queries and analyzing security logs. It helps correlate related events and identify relevant evidence faster, allowing our SOC to investigate incidents more efficiently and focus on critical security activities. An example of time savings I have observed is with AI SIEM threat hunting. AI performed investigation using natural language and quickly identified relevant activity, which reduces the time spent on manual log analysis and allows our SOC to focus on validating findings and responding to threats. It also simplifies detection rule development by generating and refining queries.
I have used automated workflows to streamline repetitive security operations tasks. Automating routine activities such as alert enrichment or event handling and response helps reduce manual intervention and improves operational efficiency. This also reduces alert fatigue, allowing our SOC team to focus more on threat investigation and incident response rather than repetitive administrative tasks.
The automated workflows have the potential to reduce false positives by enriching the alerts with contextual information and filtering. This has reduced unnecessary alert handling and improved SOC efficiency. However, the effectiveness depends on the quality of detection rules and workflow configurations. Continuous tuning and validation will remain necessary to ensure genuine intrusions are not overlooked.
I find SentinelOne Singularity AI SIEM efficient in supporting our SOC operations. Its AI-powered threat hunting and investigation capabilities help reduce the effort of manually analyzing security logs and correlating events. The platform also assists in developing and refining detection queries, improving the efficiency of threat investigations. However, the accuracy of the generated queries and the need for manual validation can affect the overall efficiency, particularly when working with complex or third-party log sources.
I assess SentinelOne Singularity AI SIEM efficiency by measuring how much time it saves in daily SOC operations, how accurately it identifies threats, and how much manual work remains. I also assess the efficiency of SentinelOne Singularity AI SIEM based on security activities done manually for threat hunting, detection, and incidents. For example, investigating external port scanning activity traditionally requires manually filtering firewall logs, correlating events, and calculating investigation reports. Assisted investigation helps simplify this process by identifying relevant events and assisting with query development. This improves detection efficiency, although the generated queries still require analysts' modification.
If a Windows endpoint starts communicating with a suspicious external IP, SentinelOne Singularity AI SIEM can correlate firewall logs with endpoint telemetry to help identify the affected system. If the activity is confirmed as malicious, the SOC can isolate the endpoint. SentinelOne Singularity AI SIEM does not directly prevent system downtime. It is entirely dependent on detection quality, response speed, and whether required mitigation and response actions were taken. SentinelOne Singularity AI SIEM can help reduce the potential impact of security events on system availability by improving threat detection and investigation speed.
I believe my organization's security posture has improved with the implementation of SentinelOne Singularity AI SIEM. The platform provides better visibility into security events across multiple data sources and helps identify suspicious activities more efficiently. Its AI-powered threat hunting, event correlation, and investigation capabilities support faster threat identification and improve our ability to detect potential attacks. It also assists in developing and refining detection rules, helping us address detection gaps and strengthen our monitoring capabilities. Overall, the platform has improved our security visibility and investigation efficiency, while continuous detection tuning and analysis remain essential to maintaining an effective security posture.
Consolidating security data from multiple sources into SentinelOne Singularity AI SIEM has helped streamline our SOC operation by providing a centralized view of security events. Instead of switching between different tools to investigate suspicious activities, analysts can correlate and analyze data from multiple sources within a single platform. This improves investigation efficiency, reduces manual effort, and simplifies threat hunting. It helps our team identify relationships between events that might otherwise remain unnoticed.
What is most valuable?
The best features of SentinelOne Singularity AI SIEM are the AI-powered threat hunting and investigation, natural language search, and the ability to query data so I can search with my own language with Purple AI. Custom detection rules and correlation of security events across multiple data sources, real-time threat detection and alerting, integration with SentinelOne EDR and XDR and third-party security products, data normalization and log parsing, historical log analysis for identifying attack patterns, and automated response and orchestration workflows are all valuable.
AI-powered threat hunting using natural language stands out the most to me. It allows me to investigate security data using plain language questions instead of manually writing complex queries. This reduces the time required for threat hunting and makes investigations more accessible for analysts who are less familiar with query languages. I was not that much familiar with the SentinelOne query language before. During the first six months, I was not familiar with the query language, but now I am an expert. However, analysts who are less familiar with query languages can use Purple AI to query SentinelOne data using plain English.
Another standout feature worth mentioning is AI-assisted detection engineering. Unlike simply using AI to summarize events, this focuses on helping me develop, investigate, and refine detection logic. It can make detection engineering more accessible and reduce the manual effort involved in writing and troubleshooting queries. Other features that may stand out are assisted investigation, explainable AI verdicts, and OCSF normalized data. Assisted investigation is a strong feature to mention alongside the features I have mentioned.
What needs improvement?
SentinelOne Singularity AI SIEM can improve in several areas. AI accuracy is one area where the platform can improve the accuracy of AI-generated queries and investigation findings, especially for complex log formats. Detection rule creation should be easier, making it simpler to convert AI-generated queries into production-ready detection rules. False positive reduction is another important area where improved detection tuning is needed to reduce unnecessary alerts and manual triage. For example, SentinelOne Singularity AI SIEM can catch SentinelAgent.exe as a potential threat, but it should not because it is the agent of SentinelOne itself. Third-party integrations should be improved because the platform does not integrate with some Microsoft-related products currently. Expanding out-of-the-box integrations and simplifying the onboarding of non-SentinelOne data sources would be beneficial.
Log parsing should be improved by enhancing automatic extraction and normalization for custom and third-party logs. Investigation transparency should provide clearer explanations of why an event was classified as suspicious or malicious because the AI is constantly classifying SentinelOne agent as suspicious. The platform should support more formats and optimize costs by improving query execution and optimizing data and storage costs.
The accuracy of SentinelOne Singularity AI SIEM is generally useful for threat hunting and security investigations. However, AI-generated queries may require manual validation, particularly when dealing with complex log formats or custom data sources. Sometimes, query results may need refinement to avoid false positives or may miss some relevant events. Improving query accuracy, field mapping, and consistency across third-party observability would make the platform more reliable and reduce the need for manual troubleshooting.
