Organizations around the globe are rapidly adopting AI and embracing accelerated creativity and output, but with this vast opportunity come enormous challenges: visibility, compliance, security, control. From the growth of AI tool usage outside IT and infosec to the emergence of autonomous AI agents and agentic workflows, the undeniable benefits of AI often open the door to novel cyber threats and data privacy concerns, but even more often, to misuse and leakage of sensitive information.
SentinelOne pioneered AI Cybersecurity beginning at the endpoint and this strategy has rapidly evolved to the cloud, AI SIEM, and generative and agentic AI to protect every aspect of enterprise security. Now, we’re taking that strategy a step further, signing a definitive agreement to acquire Prompt Security – a rapidly growing company empowering and enabling organizations to use AI and AI agents securely – today. The immediate visibility and control Prompt Security delivers to all employee use of GenAI applications in the work environment is unparalleled.
Embrace AI without compromising visibility, security, or control
Prompt Security CEO Itamar Golan and his team were early champions of AI as a force for productivity, innovation, and transformation. As a cybersecurity veteran of Orca and Checkpoint, Golan was quick to realize that security risks would be the single biggest blocker to widespread AI adoption. This need is what has driven Prompt Security’s approach from the start – providing companies with the ability to encourage and deploy employee AI usage without compromise.
Prompt Security’s technology helps organizations by integrating across browsers, desktop applications, and API’s. This includes real-time visibility into how AI tools are accessed, what data is being stored, and automated enforcement to prevent prompt injections, sensitive data leakage, and misuse.
This design and approach is highly complementary to SentinelOne’s AI strategy and the Singularity Platform; creating a unique, integrated layer for securing AI in the enterprise – protecting tools where and how they are used, and creating customer value in a way no other solution in the market can match.
The Prompt Security Difference
Prompt Security enables organizations and users to confidently leverage tools like ChatGPT, Gemini, Claude, Cursor, and other custom LLMs by providing IT and security teams visibility, security, and real-time control – even over unmanaged AI use.
Real-Time AI Visibility
Prompt Security’s lightweight agent and browser extensions automatically discover both sanctioned GenAI apps and unsanctioned Shadow AI wherever employees work. This includes browsers, desktop IDEs, terminal-based assistants, APIs, and custom workflows. The platform maintains a live inventory of usage across thousands of AI tools and assistants. Every prompt and response is captured with full context, giving security teams searchable logs for audit and compliance. This is a great complement to our existing presence on the endpoint, and will enable us to accelerate our GenAI DLP capabilities.
Policy-Based Controls
Granular, policy-driven rules let teams redact or tokenize sensitive data on the fly, block high-risk prompts, and deliver inline coaching that helps users learn safe AI practices without losing productivity.
AI Attack Prevention
The platform inspects every interaction in real time to stop prompt injection, jailbreak attempts, malicious output manipulation, and prompt leaks. It is designed to maintain low latency so users experience no disruption.
Model Agnostic Coverage
Safeguards apply uniformly across all major LLM providers including OpenAI, Anthropic, and Google, as well as self-hosted or on-prem models. The fully provider-independent architecture fits into any stack, whether SaaS or self-hosted.
MCP Gateway Security
Prompt Security’s MCP Gateway sits between AI applications and more than 13,000 known MCP servers, intercepting every call, prompt template, and response. Each server receives a dynamic risk score, and the system enforces allow, block, filter, or redact actions.
The Future of AI Security
AI is the most transformative force in the world today, but without security, it becomes a liability. SentinelOne has long set the standard on how AI can transform cybersecurity. This acquisition unlocks a new frontier of platform expansion for SentinelOne and represents a step forward in our AI strategy – from AI for security to security for AI. It cements SentinelOne’s leadership in securing the modern AI-powered enterprise, and it also puts in the center the main thing that acquisitions are about- solving real customer problems, improving security, and creating tangible value for security teams- allowing them to lead their business safely and responsibly to the AI age.
Protecting the usage of AI tools without compromising safety or inhibiting productivity is critical to their continued adoption and together, SentinelOne and Prompt Security provide the tools and confidence to make that a reality.
The ink may still be drying but the next chapter of SentinelOne’s growth story has officially begun. On behalf of all Sentinels, our partners, and our customers, I couldn’t be happier to welcome the Prompt Security team to SentinelOne!
