What is Prompt Security?

Prompt Security is an enterprise-grade AI defense platform, now part of SentinelOne, that secures the use of Generative AI by preventing data leaks, blocking threats, and governing AI usage.

How does it handle Shadow AI?

The platform automatically discovers and monitors any AI tools being used by employees, allowing IT teams to gain visibility into unmanaged AI sprawl and enforce acceptable use policies.

Does it slow down AI application performance?

The platform is designed for minimal latency, using efficient inspection layers like browser extensions and endpoint sensors to secure interactions without disrupting the user experience.

Can it protect against prompt injection?

Yes, it features advanced algorithms to detect and block prompt injection, jailbreaks, and other adversarial attempts to manipulate LLM behavior.

Does it support local LLMs and agents?

Yes, it provides a dedicated endpoint AI security agent that can monitor local LLMs, autonomous agents, and MCP server communications that bypass traditional network proxies.

How do I get started?

Interested organizations can book a demo through the SentinelOne website to see the platform in action and receive a tailored quote.
