Windsurf Security Basics

Overview

Security best practices for Windsurf AI IDE: controlling what code Cascade can see, preventing secrets from leaking into AI context, managing telemetry, and configuring workspace isolation for regulated environments.

Prerequisites

• Windsurf installed
• Understanding of Codeium's data processing model
• Repository with identified sensitive files

Instructions

Step 1: Exclude Secrets from AI Indexing

Create .codeiumignore at project root (gitignore syntax):

# .codeiumignore — files Codeium/Windsurf will NEVER index or read

# Secrets and credentials
.env
.env.*
.env.local
credentials.json
serviceAccountKey.json
*.pem
*.key
*.p12
*.pfx

# Cloud provider configs
.aws/
.gcloud/
.azure/

# Infrastructure secrets
terraform.tfstate
terraform.tfstate.backup
*.tfvars
vault-config.*

# Customer data
data/customers/
exports/
backups/
*.sql.gz

Default exclusions (automatic): Files in .gitignore, node_modules/, hidden directories (. prefix).

Enterprise: Place a global .codeiumignore at ~/.codeium/ for org-wide exclusions.

Step 2: Disable Telemetry (If Required)

// Windsurf Settings (settings.json)
{
  "codeium.enableTelemetry": false,
  "codeium.enableSnippetTelemetry": false,
  "telemetry.telemetryLevel": "off"
}

Step 3: Configure AI Autocomplete Exclusions

Disable Supercomplete for file types that commonly contain secrets:

{
  "codeium.autocomplete.languages": {
    "plaintext":
