SentinelOne Expands AI Security Platform With New Data Protection Tools

SentinelOne has introduced new Data Security Posture Management (DSPM) capabilities to its AI Security Platform, focusing on protecting AI systems from data ingestion through runtime execution. The development is part of the company’s ongoing efforts to address risks associated with AI data pipelines and enhance overall platform security.

The DSPM features, announced in February 2026, are intended to prevent sensitive or high-risk data from being incorporated into AI pipelines. According to SentinelOne, these measures are designed to address issues such as data memorization and pipeline poisoning before the training phase begins.

These new capabilities build on SentinelOne’s existing offerings, which include cloud infrastructure posture management, AI security posture management, runtime workload protection, employee GenAI security, and agent security. The company has positioned these tools as components of a unified AI Security Platform.

SentinelOne previously launched its AI Security Posture Management (AI-SPM) in November 2024. The AI-SPM provides organizations with visibility into both known and shadow AI services, detection of misconfigurations and vulnerabilities in AI applications, and visualization of potential attack paths.

What the numbers show

• DSPM expansion was announced on February 6, 2026
• AI-SPM was introduced in November 2024
• Prompt Security was acquired by SentinelOne in August 2025
• Observo AI integration occurred at OneCon 2025

In August 2025, SentinelOne acquired Prompt Security as part of its strategy to strengthen GenAI and agent security. The acquisition aimed to provide real-time oversight and control over AI usage, with the goal of preventing data leakage and prompt injection attacks.

At OneCon 2025, SentinelOne integrated Observo AI into its Singularity AI SIEM, enabling AI-native data pipelines for optimized streaming data ingestion and analytics. This integration supports autonomous threat detection and response within the platform.

During the same event, SentinelOne introduced Prompt Security offerings for employees, AI code assistants, and AI applications, with general availability for most features and a beta release for Prompt Security for Agentic AI. These offerings are designed to enhance visibility and control over generative AI usage and to secure AI agents.

SentinelOne’s approach to AI security has involved combining multiple technologies and recent acquisitions to address evolving risks in AI environments. The company continues to develop its platform to provide end-to-end protection for organizations deploying AI systems.
