Use cases

What Slopfence protects against

ChatGPT & Claude

Intercept outgoing messages before they reach any AI model — block or alert on PII, credentials, and confidential content in real time.

File Upload Scanning

Every DOCX, XLSX, PPTX, PDF and text file uploaded to an AI tool is extracted and scanned against your DLP rules before it leaves the browser.

Credential Protection

AWS keys, API tokens, passwords, and secrets are caught by pattern matching before employees accidentally paste them into an AI prompt.

PII & Regulated Data

Social security numbers, credit card numbers, phone numbers, and email addresses are flagged automatically without any custom configuration.

Department Policies

Finance, Legal, and Engineering can each have stricter or looser rulesets. Policies are scoped per department and applied automatically.

Compliance Audit Trail

Every message and file that triggered a rule is logged with the user, platform, timestamp, and matched rule — ready for your next audit.

How it works

Up and running in minutes

01

Install the extension

Deploy the browser extension to your team. Supports Chrome and Edge. Each download is pre-configured for your organisation — no manual setup.

02

Configure your policies

10 standard DLP rules ship automatically. Add custom regex or keyword patterns. Scope stricter rules to specific departments in minutes.

03

Protect in real time

Every prompt and file across ChatGPT, Claude, and Gemini is scanned. Violations are blocked or logged instantly — no VPN, no proxy.

Under the hood

No proxy. No traffic rerouting. Pure browser.

The Chrome extension patches window.fetch and XMLHttpRequest on AI tool pages. When a message is submitted, the extension intercepts it before the network call completes, scans against your DLP rules using pattern matching, and either cancels the request (block) or lets it through (alert + log). No traffic passes through Slopfence servers. Only alert metadata — never full message content — is sent to your dashboard.

Features

Everything you need to secure AI

Real-time interception

Patches fetch and XHR at the browser level — zero latency, zero proxy.

Office doc parsing

Extracts text from Word, Excel, PowerPoint and PDF files via JSZip + pdf-parse.

Block or alert

Per-rule severity — block silently cancels the request; alert logs and continues.

Auto-classification

Detects Confidential, Restricted, Internal and other markers in file content.

10 default policies

Every org starts with SSN, card numbers, AWS keys, PII patterns and more out of the box.

Intel risk scoring

Deduplicates noise and surfaces only genuine threats with a 0–100 risk score.

Pricing

Simple, flat pricing

No per-seat fees. Pay for your org, not per head. All plans include a 14-day free trial.
