data into AI chatbots

Sensitive prompts are slipping through unsecured channels

The launch of ChatGPT marked the beginning of employees routinely using generative AI tools to summarize, analyze, and interact with classified data through unsecured, consumer-grade browsers.

Once sensitive data is entered into AI prompts, it’s unclear how it’s stored, used, or shared. Public leaks of chat logs have exposed proprietary information, API keys, and can enable code injection. Legacy security frameworks like SASE can’t monitor prompt activity, and enterprise browsers fail to protect AI usage on popular consumer browsers.

Obsidian Security closes this gap with real-time prompt controls to locally enforce AI data policies.

Frequently Asked Questions

What is AI prompt security?

AI prompt security is the practice of safeguarding your data from being inputted into generative AI systems outside of corporate policies, either through unintended behavior or insider threat. It focuses on preventing risks such data leakage or exposure by controlling how prompts are  handled by users.

Why does prompt security matter in the enterprise?

Without adequate prompt controls, employees can input corporate or sensitive data into GenAI tools unknowingly, leading to data leaks, compliance violations, or even prompt injection attacks. Legacy security tools like SASE or CASB lack the necessary monitoring capabilities to protect prompt-level interactions.

Do current data loss prevention solutions protect GenAI prompts?

Some solutions like Enterprise Browsers are good policy enforcement tools to put guardrails around what data users input into AI chatbots. However, most organizations struggle with total adoption of these tools, allowing for users to still use popular browsers like Chrome or Edge. Without protections in these browsers, users will not have any controls into the data they can submit to GenAI prompts.

How does Obsidian Security enforce prompt‑level protection?

Obsidian delivers a lightweight, browser‑level enforcement solution for AI data policies through real‑time prompt inspection and keyword recognition. It blocks sensitive data submissions, supports custom rulesets, and integrates with SaaS access controls to secure AI usage across enterprise environments.

Can prompt security stop data leaks even if employees use personal GenAI accounts?

Yes. Obsidian can enforce prompt restrictions and alerts for both managed and unmanaged AI usage, ensuring policy adherence even when GenAI tools are accessed via unmanaged or personal environments.
