Security in Automations: Best Practices

Automations often process sensitive business data and have access to critical systems. Security of these workflows should therefore be considered from the start.

Why Security Matters in Automations

Automations are often the link between different systems. They have access to CRM data, email accounts, financial systems, and more. A compromised workflow can therefore have far-reaching consequences:

• Data leaks and compliance violations (GDPR)
• Unauthorized access to connected systems
• Manipulation of business processes
• Reputational damage

Credential Management

API keys, passwords, and tokens are the heart of any automation. Here are the most important best practices:

Never Store Credentials in Plain Text

Never store credentials directly in workflows or configuration files. Instead, use your automation platform's credential management or external secret managers like HashiCorp Vault.

Principle of Least Privilege

Grant only the minimum necessary permissions. If an automation only needs to read data, use a read-only token. If only certain resources are needed, restrict access accordingly.

Regular Rotation

Rotate API keys and tokens regularly - ideally every 90 days. Document which credentials are used where to simplify rotation.

Security Checklist for Automations

Use this checklist for every new workflow:

• ☐ Credentials stored securely (not in plain text)
• ☐ Minimum necessary permissions granted
• ☐ Webhook endpoints secured
• ☐ Sensitive data masked in logs
• ☐ Error handling implemented
• ☐ HTTPS for all external connections
• ☐ Data processing agreements reviewed
• ☐ Access rights documented
