AI usage has moved faster than traditional security controls. Employees now use AI in browsers, desktop apps, and copilots—often with sensitive data, customer context, source material, and documents. The security problem is no longer just model security or cloud gateway security. It is interaction security.
Every time someone pastes confidential information into ChatGPT, uploads a document to Claude, or reviews an AI-generated response containing suspicious links, there is an interaction that deserves protection. PromptVigil was built to address exactly this gap.
AI Interaction Security Layer
What PromptVigil Does
PromptVigil sits where users interact with AI. It helps detect and prevent risks before they become incidents:
- Sensitive data leakage — Catch API keys, credentials, PII, and confidential content before submission
- Prompt injection — Detect manipulation attempts hidden in prompts, files, or page content
- Unsafe attached files — Inspect uploads for embedded risks before they reach AI
- Risky AI-generated responses — Flag suspicious outputs, hallucinated content, or unsafe recommendations
- Suspicious links and handoffs — Warn about untrusted URLs in AI responses
- Untrusted copied content — Detect risks in content pasted from websites or documents
From AI usage risk to governed interaction
Common Risks
PromptVigil Controls
Why Browser and Desktop Coverage Matters
Many AI interactions happen outside sanctioned APIs. Teams use browser-based AI tools like ChatGPT and Claude, desktop AI applications, file attachments, copy/paste workflows, and page-review interactions. Traditional API gateways and network proxies miss most of this activity.
PromptVigil starts with browser extensions and desktop agents so protection happens at the point of interaction—before risky content is submitted, not after it has already left the device.
Local-First and Privacy-Preserving
PromptVigil is designed to inspect locally where possible, minimize what is logged, and focus on high-signal security events rather than broad surveillance. We do not capture or store full prompt content by default. Instead, we surface actionable security signals—warnings, blocks, and redactions—without requiring organizations to send all AI activity through a central logging system.
For teams that need audit trails, PromptVigil supports optional logging of security events with configurable retention and export controls.
Who It Is For
PromptVigil is built for security teams, IT administrators, compliance leaders, and AI-forward business teams that want employees to keep using AI while reducing risk. Whether you are a startup with ten people using Claude daily or an enterprise with thousands of employees across ChatGPT, Gemini, and Copilot, PromptVigil provides a practical layer of protection.
Where We Are Going
PromptVigil is just getting started. Our roadmap includes:
- Deeper document security with structured file inspection
- OCR and scanned-document inspection for image-based content
- Expanded desktop app coverage beyond browsers
- Enterprise policy controls with role-based administration
- Optional gateway/API coverage for non-browser AI traffic
