What is AI security, and why does it matter?

AI security protects the tools, data, and infrastructure that power AI across your organization. As employees adopt AI assistants, teams build custom AI apps, and autonomous agents take on operational tasks, each creates new attack surfaces. AI security gives you visibility into that activity, enforces policy in real time, and prevents data exposure, prompt injection, and unauthorized access before they become incidents.

How does SentinelOne protect employee AI usage?

SentinelOne's Prompt Security for Employees discovers AI tool usage across your workforce, enforces acceptable-use policies in real time, and applies selective data redaction so sensitive information never reaches third-party models. Real-time coaching guides employees toward safe AI practices without blocking productivity, covering 15,000+ AI tools.

What is AI-SPM, and how does it differ from DSPM?

AI Security Posture Management (AI-SPM) treats AI systems as first-class assets, providing unified inventory, continuous posture assessment, and visibility into misconfigurations across training pipelines, inference endpoints, and managed AI services. Data Security Posture Management (DSPM) focuses on the data layer, discovering and classifying sensitive data and enforcing policies that prevent high-risk datasets from feeding AI pipelines. Together, they secure AI from data to runtime.

How does SentinelOne secure homegrown AI apps and agents?

SentinelOne provides dedicated controls for custom AI applications and agentic workflows. For AI apps, this includes protection against prompt injection, sensitive data exposure, and unsafe interactions. For AI agents, policy-based governance defines what agents can access, retrieve, and execute, so autonomous workflows expand without expanding risk.

What does "Shift Left" mean for AI security?

Shifting AI security left means integrating security into AI development before code reaches production. SentinelOne provides automated code and AI secrets scanning alongside AI red teaming that surfaces prompt injection, data poisoning, and policy bypass risks during development, not after deployment.

Can SentinelOne secure AI across cloud and on-premises environments?

Yes. Singularity™ Platform unifies AI security across cloud workloads, on-premises infrastructure, and hybrid environments. DSPM, AI-SPM, and Prompt Security operate across your full AI footprint, providing consistent visibility and enforcement regardless of where AI is built, trained, or deployed.

Today's Reality

AI is Everywhere. Your Controls Aren’t.

Shadow AI

Employees Use AI Defenders Can’t See

Workforce AI adoption outran security review. Tools, models, and prompts move through endpoints daily. No inventory. No enforcement.

Data Exposure

One Prompt Can Leak Data

Sensitive data lands in third-party AI through everyday prompts. Once it's out, it trains models you don't own. You can't get it back.

Agentic Vulnerability

AI Agents Have Access, But Not Judgment.

Agents access tools, pull data, and trigger actions on behalf of users. One poisoned input turns into a chain of decisions no one approved.

The SentinelOne Advantage

Security for Every AI Interaction

Why SentinelOne?

Built on AI. Built to Protect AI.

SentinelOne delivers Autonomous Security Intelligence across the security lifecycle, combining AI-native protection, human amplification, and an intuitive experience to secure AI without adding complexity.

AI-Native from the Start

SentinelOne was built on AI and machine learning as core principles, not bolted on later. That foundation enables real-time analytics, behavioral understanding, and safe automation at enterprise scale.

Autonomous by Design

SentinelOne uses AI to redefine security operations. Purple AI powers the autonomous SOC by automating triage, investigation, and response so teams can focus on judgment and direction.

Unified Across the Enterprise

Unified visibility across the enterprise starts with unified data. SentinelOne connects endpoint, cloud, identity, and AI telemetry so teams can see risk clearly without stitching tools together.

Powerful Protection. Zero Complexity.

AI security should reduce friction, not add to it. SentinelOne deploys in minutes and uses natural-language policy configuration to keep teams productive while keeping data safe.
