AI interaction security

The runtime security layer for AI interactions

PromptVigil protects prompts, pasted content, file uploads, risky AI responses, suspicious links, and indirect prompt injection across the AI tools people already use.

AI risk lives in the interaction layer

The biggest operational AI failures usually happen at the moment people paste, upload, trust, or act — not only inside the model itself.

Sensitive data gets pasted too easily

Users often share customer data, secrets, payment details, or internal notes before anyone realizes what left the page.

Files can carry hidden risk

Documents, spreadsheets, and copied snippets can contain unsafe instructions, metadata, or embedded content that changes what the AI is asked to do.

AI responses can still steer unsafe action

A risky answer can push a user to click, sign in, reveal a code, transfer data, or trust a fake verification flow.

Model safety is not enough

Even strong model guardrails do not solve the cross-app interaction problem when users work across multiple AI tools and browser workflows.

What makes PromptVigil different

Most alternatives solve one slice of the problem. PromptVigil is built to protect the full AI interaction path.

More than prompt privacy

PromptVigil protects prompts, pasted content, file uploads, risky responses, and suspicious links — not only obvious oversharing.

More than one AI ecosystem

It works across major AI apps instead of being limited to a single model vendor or browser ecosystem.

More than logging

PromptVigil warns, blocks, redacts, and creates safer remediation paths instead of only telling users something risky happened.

More than governance dashboards

It sits inline at the exact point where risky AI interactions happen, then connects that protection to team policy and audit controls.

Protect the full interaction path

PromptVigil is designed around the real places AI workflows break down.

Prompt and paste protection

Catch sensitive or risky content before it leaves the prompt box.

File upload scanning

Inspect documents before upload and offer safer redacted-copy workflows where supported.

Risky response detection

Warn when AI-generated guidance appears manipulative, unsafe, or operationally risky.

Suspicious-link interception

Flag risky destinations before the browser opens them.

Indirect prompt injection detection

Detect instruction-like content hidden in webpages, copied snippets, files, and low-visibility structures.

Team policy and audit controls

Extend user-side protection into rollout, policy, audit, and admin review flows.

Protect against hidden instructions, not just sensitive text

PromptVigil helps detect instruction-like content embedded in webpages, pasted snippets, uploaded files, hidden document structures, and risky AI responses that try to override the user's intent.

Built for real AI workflows

PromptVigil is designed to protect how people actually use AI today: typing prompts, pasting snippets, uploading documents, reviewing responses, and following links.

Block before send

PromptVigil warns or blocks risky prompt content before it reaches the model.

Create safer file copies

For supported file flows, PromptVigil can generate redacted copies instead of forcing users to start over manually.

Catch risky responses

PromptVigil flags unsafe guidance, suspicious requests, and manipulative response patterns after the model answers.

Review hidden instructions

PromptVigil can detect hidden or low-visibility instruction-like content in page-review and indirect prompt injection flows.

See protection history

Users and teams can review high-signal activity, outcomes, and current protection posture from the workspace and admin views.

Beyond prompt privacy

PromptVigil is broader than privacy-only extensions and more inline than governance-only tools.
