Shadow AI detection

Shadow AI — unsanctioned use of AI tools by employees — is the fastest-growing blind spot in enterprise security. Without detection, security teams cannot assess or mitigate the risk. PromptWall provides discovery, classification, and governance for every AI interaction.

The scope of the problem

Enterprise employees use an average of 3–5 different AI tools without IT approval. ChatGPT, Claude, Gemini, Perplexity, Copilot, and dozens of AI browser extensions create unmonitored data exfiltration channels. Each interaction is a potential data leak — and security teams have zero visibility.

The challenge is not that employees are acting maliciously. Most shadow AI usage improves productivity. The problem is that sensitive data in AI prompts — customer PII, source code, credentials, and internal documents — leaves the organization without any security inspection.

Discovery and classification

PromptWall discovers AI usage across three surfaces:

• Browser — Chrome extension monitors interactions with web-based AI tools (ChatGPT, Claude, Gemini, Perplexity, and custom web apps).
• Editor — VS Code and Cursor integrations capture Copilot, inline completions, and AI-assisted coding workflows.
• CLI / API — Local proxy captures curl requests, Python scripts, and any programmatic AI API usage.

Each interaction is classified by AI provider, data sensitivity, user identity, and policy compliance.

From detection to governance

Discovery is step one. The real value is governance — moving from "we don't know what's happening" to "every AI interaction is inspected and governed." PromptWall enables a graduated response:

1. Discover — Identify all AI tools in use, usage patterns, and data sensitivity profiles.
2. Assess — Classify usage by risk level. Quantify data exposure with PII detection metrics.
3. Govern — Approve low-risk tools with inspection. Apply DLP controls for medium-risk. Restrict or block high-risk usage.
4. Monitor — Continuous monitoring with SOC integration ensures governance stays effective over time.

What security teams see

The shadow AI dashboard provides real-time visibility into:

• Total AI interactions by provider (ChatGPT, Copilot, Claude, etc.)
• Sensitive data exposure rate (percentage of prompts containing PII)
• Top users by interaction volume and risk level
• Unapproved AI tools detected in the organization
• Policy violation trends over time
• Compliance posture for audit requirements
