TL;DR

Prompt Security (part of SentinelOne) is a platform designed for mid-sized and large enterprises that enables secure AI adoption without risking data leakage, compliance violations, or losing visibility into what employees share with public AI models.

The platform protects four key areas: employees using AI tools in their daily work, developers relying on coding assistants such as Copilot and Cursor, internally developed LLM-based applications, and autonomous AI agents. It operates in real time, stopping threats before sensitive data leaves the organization rather than reacting after an incident occurs. Deployment is fast, and the entire environment can be managed through a single centralized platform.

In today’s rapidly evolving business landscape, Generative AI (GenAI) has become impossible to ignore. From marketing and finance to human resources and software development, AI is now present in virtually every department of a modern organization. However, alongside its tremendous potential for innovation and growth comes a new category of cyber risks that keeps security leaders awake at night.

How can organizations empower employees to use cutting-edge AI tools without risking the exposure of trade secrets or losing control over sensitive data? The answer is Prompt Security (A SentinelOne Company) — a platform specifically designed to ensure that AI adoption does not compromise organizational security.

New Horizons, New Risks

Traditional security solutions are often insufficient when facing the unique threats associated with Large Language Models (LLMs). Employee use of AI and the development of AI-powered systems introduce a broad spectrum of risks affecting security, compliance, and trust.

The most significant challenges organizations face today include:

Shadow AI

Employees frequently use unapproved AI tools without the knowledge or oversight of IT teams, creating blind spots in the organization's security strategy.

Prompt Injection

Attacks that manipulate AI model inputs to bypass safeguards and force the model to perform malicious or unintended actions.

Sensitive Data Exposure

The risk that confidential information, source code, or personal data may be submitted to public AI models during everyday work activities.

Harmful LLM Responses

AI-generated content may be inappropriate, harmful, inaccurate, or inconsistent with a company's brand image, potentially causing reputational damage.

Unsecured AI Agents

A relatively new risk category involving autonomous AI agents capable of performing unauthorized actions within corporate environments.

Prompt Security: A Comprehensive Approach to Enterprise AI Security

Prompt Security integrates with an organization's existing environment to secure every interaction with AI — from simple employee prompts to complex custom applications powered by LLMs. The platform is built around four pillars of protection, each addressing different enterprise requirements.

Secure Workforce AI Adoption

This capability allows employees to freely use AI tools without compromising data privacy or regulatory compliance.

Key capabilities include:

• Observability: Discovery and monitoring of all AI tools used across the organization, helping eliminate Shadow AI risks.
• Data Privacy: Automatic data anonymization and enforcement of controls governing what information can leave the organization.
• Employee Education: Real-time, non-intrusive guidance that helps users adopt AI securely and responsibly.

AI Code Assistants

Assistants such as GitHub Copilot and Cursor are transforming software development but can also become sources of API key exposure, intellectual property leakage, and privacy risks. Prompt Security enables organizations to:

• Protect Secrets and PII: Automatically sanitize code and remove sensitive information before it is submitted to AI coding assistants.
• Gain Full Visibility and Control: Track AI usage throughout software development lifecycles and detect privacy violations.
• Leverage Broad Compatibility: Integrate with thousands of tools and support nearly 30 programming languages.

Homegrown AI Applications

For organizations building their own AI-powered applications, Prompt Security provides critical guardrails that enable them to:

• Block Attacks: Protect applications from prompt injection, jailbreak attempts, and Denial-of-Wallet attacks.
• Moderate Content: Prevent users from being exposed to harmful, inappropriate, or unsafe AI-generated content.
• Ensure Privacy: Filter and mask sensitive data when communicating with external LLMs and vector databases.

Agentic AI Usage

As autonomous AI agents become increasingly common, Prompt Security provides governance and oversight of agent behavior. This includes risk assessments based on permissions and activities, as well as enforcement of least-privilege controls before agents perform actions in CRM systems, databases, or other enterprise environments.

Why Choose Prompt Security?

Many AI security solutions are available on the market, but Prompt Security stands out through its unique approach and effectiveness. It is a modular and scalable platform designed to evolve alongside the rapidly changing AI technology stack, whether an organization is just beginning its AI journey or has already deeply integrated AI into its operations.

Key differentiators include:

Broadest Coverage

Prompt Security is one of the few platforms capable of protecting employees, AI applications, coding assistants, and AI agents within a single solution. Instead of patching security gaps with multiple disconnected tools, organizations gain a unified security layer managed from a centralized platform.

Real-Time Protection

Prompt Security stops threats at the moment they occur without slowing innovation or disrupting daily workflows. This represents a significant advantage over reactive solutions that analyze incidents after the fact. Intervention occurs before sensitive data leaves the organization.

Fast Time to Value

The platform is known for simple integration with existing IT environments and rapid business value delivery. For security teams, this means moving from purchase to effective protection without lengthy implementation projects.

Trusted by Industry Leaders

More than 75 enterprises, including Fortune 500 companies, already rely on Prompt Security. In addition, Gartner has recognized Prompt Security as a Representative Vendor in the AI TRiSM (AI Trust, Risk and Security Management) market, a category expected to become a standard requirement for mature organizations adopting AI technologies.

Which Organizations Benefit Most from Prompt Security?

The platform is available to organizations with at least 700 endpoints, making it particularly suitable for medium-sized and large enterprises with established IT infrastructures.

Regulated Industries

Banking, financial services, insurance, healthcare, and the public sector. In these industries, uncontrolled sharing of information with external AI models can lead not only to data breaches but also to serious legal, regulatory, and financial consequences.

Software Development Organizations and IT Teams

Organizations where developers routinely use coding assistants such as GitHub Copilot and Cursor. These environments face elevated risks of exposing API keys, authorization tokens, and proprietary source code, potentially resulting in financial losses or loss of competitive advantage.

Large Enterprises with Distributed Teams

The larger and more geographically distributed an organization becomes, the more difficult it is to centrally manage which AI tools employees are using. The phenomenon of Shadow AI has become particularly common in large enterprises.

Prompt Security provides security teams with complete visibility into which AI applications and models employees use, enabling informed risk management rather than risk ignorance.

Organizations Handling Sensitive Information

Law firms, consulting companies, R&D teams, and financial institutions—any environment where employees routinely work with privileged documents, client information, or valuable intellectual property.

In such organizations, a single accidental upload of confidential information to a public AI model can result in severe reputational, legal, and financial consequences.

AI Should Be an Enabler, Not a Source of Fear

Prompt Security’s mission is to help organizations confidently embrace the next era of technology.

Rather than restricting AI access out of fear of the unknown, businesses can build trust among customers and employees while ensuring their data remains protected.

Unified Governance transforms AI from a potential risk into a competitive advantage. Through real-time visibility and precise policy enforcement, Chief Information Security Officers (CISOs) and Chief Technology Officers (CTOs) can focus on what matters most: innovation that drives business growth.

Introducing AI into an organization is not merely a technology decision—it is fundamentally a security and governance challenge. As part of the SentinelOne ecosystem, Prompt Security provides the capabilities required to ensure that AI transformation happens safely and responsibly.
