Slack Integration
Protect your Slack workspace from accidental data leaks with real-time PII detection and document scanning.
Ready to protect your Slack workspace?
Add PasteProof to your workspace in just a few clicks.
Overview
The PasteProof Slack app monitors your workspace for sensitive information that could accidentally be shared. When someone attempts to post a message or upload a document containing PII (Personally Identifiable Information), PasteProof immediately alerts them before the data is exposed.
Installation
Add PasteProof to Your Workspace
Visit the PasteProof Integrations page and click the "Add to Slack" button. You'll be redirected to Slack to authorize the app.
Authorize Permissions
Review the permissions PasteProof needs and click "Allow". These permissions let PasteProof monitor messages and files in channels where it's invited.
- • Messages in channels where the bot is a member
- • Files uploaded to those channels
- • User information (for notifications)
Invite PasteProof to Channels
After installation, you'll receive a welcome message with setup instructions. PasteProof can only monitor channels where it's a member, so invite it to the channels you want to protect.
Alternatively, go to Channel Settings → Integrations → Add apps → PasteProof
How to Use
Automatic Message Monitoring
Once installed, PasteProof automatically monitors messages in channels where it's a member. There's nothing you need to do—just type messages normally.
Manual PII Check: /check-pii
Use the /check-pii slash command to manually scan text before posting it. This is useful when you want to double-check something before sharing.
/check-pii {
"level": "error",
"message": "Failed to process transaction for customer_id: 99201",
"context": {
"auth_token": "bearer sk_live_51MzByuL2N0YjR1MjR0ZW5z...",
"request_payload": {
"full_name": "Robert J. Henderson",
"ssn_last_four": "1234",
"ip_address": "192.168.1.45",
"user_agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64)..."
}
}
}- • Shows each PII type with confidence level
- • Only visible to you—not posted publicly
- • Results appear in seconds
- • Review before deciding whether to share
- • Team's custom patterns are also matched. If customer_id was cu_99201 and you had a custom pattern of cu_*, it would detect and alert.
Document Scanning
When you upload a document to a channel where PasteProof is a member, it automatically scans the file for sensitive information.
• TXT, RTF
• ODT
• CSV
• ODS
